Heat Advisories Up Again: Record Highs Possible, Wind Advisories & Relief Coming

追加: 2026-05-12

[00:00:00]Meteorologist Bill Martin. It is May 12th. It's a Tuesday. There's more heat in the offing as we go through the day today. Cools off after that. There's a chance of some showers, believe it or not, for part of California, clearly the northern part. We'll look at that as well. Uh records possible again today uh in parts of the desert southwest especially. We'll take a peek at Polarmo, California. What's the story there? We'll look at Willows. Little backstory on Willows, California. Then we'll take a look at nature snacks. We also do a move where we go right to the computer models right off the top and we'll take the latest computer models and run you through what is expected over the next 24 48 to 72 hours and beyond including the chances our next chances for that rain that I mentioned.

[00:00:45]Then we go California north to south Mount Shastas all the way south to San Diego area. We look at forecast highs today tomorrow for the nation and California and then we do surf reports.

[00:00:57]So, we got a lot to do. And we also, last but not least, take a look at the birds. The baby birds up at Big Bear Lake, the Eagles. This is the system right here. It's going to bring a chance of a few sprinkles as we go into tonight and tomorrow morning. Well, look at that. This system is enough to cool us down, but it's not doing it right now.

[00:01:17]Right now, the ridge of high pressure is doing something like this. You can kind of see it, the ridge, and then it drops out here. So, this ridge is still dominant in this area. That's why the big heat is in this zone. This ridge has created a situation where we have fog along the coast and you can see it here.

[00:01:33]Fog from Cape Menescino all the way south to Insanada basically and a lot of fog pushing well inland. Not so much in the north. So, I suspect today in the next 6 hours or so from about Marin County north, the fog's going to start to clear out and that's because of this low pressure center pushing in. The low has the ability to increase the inversion. Doesn't mix out like the fog.

[00:02:01]The low is mixed out the fog here, right? Because inversions ex vertically mix the air. Fog can't really exist.

[00:02:08]It's doing the same thing as it erodess fog on the north coast. But as you get south of Ukaya area, you start to see the fog. It's not strong enough this low to mix it out all the way. So you get it deeper. And when it gets deeper, it ends up into Santa Rosa. It ends up out into Napa, uh, all the way into Liverour Valley out trying to get into the central valley and then fogged south all the way to Gilroy, um, and down towards Selenus Valley, working its way to King City. So that's a the function of a deep marine layer which is a function of this low pressure center right here that is weakening the whole system. So this heat wave that we've just experienced is winding down. This is the extreme heat warning uh for the desert southwest. As a matter of fact, today we're going to look at weather center headlines. These are the different weather service offices throughout California. We're going to go right to the computer models after that and we're going to look at the latest changes, the latest updates on the models. How's warms it going to get? Winds are going to get warmer. When is this opportunity for rain? Then we go look at live cameras. Sort of an esoteric look at California and weather and live. So this is Mount Shasta as it looks right now with that low pressure sitting offshore.

[00:03:25]So you can make the connection between right between oh that's what it looks like and this is what it it looks like on the satellite image. So we go all the way to Southern California. We look at air quality as well. We look at surf reports. We look at Ocean Beach San Francisco and then we go right to nature snacks where we look at the Eagles uh at Big Bear Lake and we go to Venice to wind down. But there's lots of interesting stuff in between. Hope you stick around. The extreme heat warning, like I said, records again possible today in parts of California. This is the heat advisory. This is for the area out of Sacramento weather service and they're saying look heat advisory again today with temperatures possible especially south of Modesto into the upper 90s low 100s. Uh the weather service out of Bakersfield or out of Fresno saying yeah we got another chance for records today. And again just highlighting what's on these guys' mind, right? So you have these weather service offices. They they um they are responsible for different regions throughout California from the north and Eureka to Sacramento to San Francisco or Monterey if you will to Oxnar to LA to um San Diego. And so they just go this is what's important the record heat and the record warmth. And that's awesome because the wind is or not the wind that's this is the choppy lake situation up in Reno. They're saying, "Yeah, we got wind advisories up around northeast California." That's in relationship to that low coming in. So, what I was going to say is, yeah, bonus, this heat wave is done after today. Not done, but it's winding down. And that's good because heat waves are do their most damage with with people. I had a woman um and this is the model, the GFS. We're going to look right at it. But I had a a nice lady email me the other day and she said, "Listen, you know, I talk about heat, how it exacerbates pre-existing conditions and her son has epilepsy, right?" And she goes, "Yeah, the heat triggers his epilepsy." So, see, there's there's lots of touch points like that, pre-existing conditions, respiratory conditions, epilepsy, which I never thought about, but it really it just it it it exacerbates and it can cause lots of problems. And the heat when it goes on numerous days, the problems compound.

[00:05:38]So, this heat wave is dying down. This is what's killing it right here. We'll take a look at that blue area. See that little knob coming in? Just tweaks to the north. This is the chance for a few sprinkles as we go into tonight and tomorrow morning in Northeast California. You see the ridge. And by the way, if you've been with me any amount of time, you're you're seeing a weather pattern or a weather map that looks like a weather map should look this time of year. Not like the last month. the last month these the blue was under the orange, right? A lot of it a lot of those lows were undercutting coming in through Southern California across the plains causing severe weather. This is more typical where the jetream lies up here divides the warm air from the cold air. It's not always that way, but it was really getting to be an unusual pattern. Now, this is more typical. So, this tweaks through and brings a chance of showers late tonight, early tomorrow morning for parts of Northern California. most likely a drizzle event.

[00:06:34]And then we look at um as we go into Wednesday, kind of warms up and those oranges, that light orange is still a few degrees above average. So temperatures will still be in the 80s in the Central Valley, not in the 100s. And then we go into Thursday and then kind of back to a normal temperature footprint for the weekend. When I say normal, that white or that light blue is typical weather for this time of year.

[00:06:58]Again, this is in the upper air, but we're making the assumption that the cooler air mass is bleeding down to the surface. And in fact, it is. So, this is interesting pattern here. This is on Saturday and Sunday. That'll keep things that's a little below average on Sunday most certainly. And then a ridge builds briefly. And then that's the pattern.

[00:07:18]Okay. So, that is at 500 millibars. This is at 8 850 millibars or at 5,000 ft.

[00:07:24]And I want you to see how the heat, the oranges, which are 10 to 15 to 20 degrees above average, the really dark oranges mostly. Well, not 15, more like 10. Looking at the scale right now, probably about 10 degrees above average on the 10 to 12. And look how quickly it comes out. This is this afternoon. The blue comes in. This is at 5,000 ft.

[00:07:46]again with the assumption that the temperatures are at 5,000 ft are bleeding down to to where we are and in fact they are. And then this is that Saturday thing with the cooler than average temperatures. So what we can do here is we'll look at daytime highs.

[00:08:02]This is actually this is um that rain chance for tonight. HR. So we go into tonight. This is Washington, Oregon, but you can see you can see at 1:00 today.

[00:08:12]You can see the low, the greens coming off of that low. And then there's it kisses the coast tomorrow, tonight and tomorrow morning around midnight to 2 in the morning. And that's it. And that's enough to slow the heat wave down. And you'll see that here in the um HR forecast maximums. So let's go right to this afternoon. And you can see right about here, this is the high from the highs from today, 93. in Reading or up in Chico. That's that's pretty darn warm. Still pretty warm along the coast.

[00:08:47]You can see where the heat is. You see the desert southwest 106, 107 in Vegas.

[00:08:53]That's today. So today's another hot day, right? That's why the heat advisories still. Um and then we're not seeing any extreme heat warnings, though. And then we go to That's today.

[00:09:02]Now we go to tomorrow. And tomorrow should be noticeably cooler. Not not cold, but noticeably cooler. In fact, there we are. So, and you see temperatures in the central valley in the low 80s up in Reading, uh mid upper 70s in Sacramento with a Delta breeze, uh and even cooler in the desert southwest. So, this is your footprint, your temperature footprint for um Wednesday. So, that's that's the impact of that low pressure center. So, you got it all. And these clouds represent these Well, let me come in a little closer.

[00:09:35]So, these clouds right here.

[00:09:38]Hopefully, this will load up for us.

[00:09:39]Sometimes it doesn't do it right away.

[00:09:41]So this clouds right here.

[00:09:44]So this is a satellite live satellite image and we go find Reading and we find Mount Shasta Rica. Not Mount Shasta is in here. Here's Lake Shasta. And you see, oh, okay. That's what high cirrus clouds look like out front of a low pressure center. And that's what it looks like in Mount Shassa or up in the This is actually from Hu Rica. Let me get a hit of coffee real quick.

[00:10:12]Notice the flow. It's coming from right to left. So that's the low, right? The south the the low is rotating counterclockwise and it's pulling the air up. That's why south winds are associated with weather. In fact, that's what you're seeing. You're seeing a south wind here in this environment. So that's what we can pick out from that.

[00:10:30]This is Crescent City. Crescent City today. Oh, hang on a sec. I'm going to get grab my temperatures. Hold on.

[00:10:37]I forgot to pick them off.

[00:10:43]Sorry for that. In the old days in TV, that would have been a major blunder.

[00:10:48]Um, temperature today in Crescent City, 63°.

[00:10:52]I keep them down. Just make sure I got him there. And then reading it today should go 93, but you know, it's 63. The fog should clear a little bit. And it should clear because of these high cirrus clouds that are up here that not because of them but be that that that those are a symptom of the low that is out there breaking up the inversion. And this inversion is going to lift right out in the next few hours I suspect. So Crescent City today again 63 degrees.

[00:11:18]This is up in northeast California.

[00:11:21]They're still throwing some big numbers around like 85 degrees. This is kind of out by Wica but you're looking towards the north. You're in the northeast.

[00:11:29]You're more towards all tourists, I guess. Just high desert. Looks like Idaho. I think this might be part of that debris field from the landslide off Mount Shassa, the ancient landslide that created all the homocks. Um, because Hua would be I think Hua's kind of over here. So, we're kind of looking I think we're looking at the back side of Mount Shassa's slide. You can correct me if you want. This is Polmo. Used to grow up in this area. I grew up in this area.

[00:11:55]Palmo was named after the Polarmo in Sicily. Early Italian immigrants said this Orville area by the dam and that's that's Highway 70 right out front, but it was named after um Sicily. Um the Sicily area and because it was so hot and plumber does get ridiculously hot, it just sits and bakes. Um they grow olives, oranges, and almonds, grapes, hot in the summer, mild in the winter.

[00:12:22]Classic Mediterranean climate. Italian immigrants named this in the 1880s. Um, in highway 70, if you ever run up through Orville on your way up to But Creek or the Feather River Canyon, this is the road you would take. And I believe that must be the Sutter Butes, huh? Yeah. Setter bees out in the distance. The Central Valley. And you know what's funny? I got to tell you, Palmo hasn't changed much at all. I mean, I grew up up there in the 60s. Pls about the same. I know. It's interesting. I think I pull Orville in here, too. Let's see if I go here. Yeah, you're looking towards Orville. There's 70. That's that intersection.

[00:12:59]Um, yeah, Orville's be nice little setting, isn't it? Then you got the tabletop mountains. These tabletops.

[00:13:05]These were lava flows. These are tabletops are awesome. These are lava flows that that um followed the contours of a river, the lava, and then it that's why it's so flat. It got drained into the rivers and then it dried and then bu thousands hundreds of thousands years later the land around the lava cap eroded to below it. So now this this is basically the bottom of the river up at the top because it the lava doesn't erode as easily. It's more aggressively stays it's more robust and the sediments and the rock around the right just erode away. So you get these really awesome features. Tabletop Mountains.

[00:13:50]This is a place uh this is looking towards Willows. This is Elk Creek and this is the sto Stony Gorge Reservoir and Willows got started because all the willow trees 1880s big migratory bird route as you know they grow a lot of rice out there. Um what do we got there? Oh, they have the Thunder Hill Raceway, which I'd heard of, but I didn't realize it was such a big deal. It's a big deal. It's like one of the best racetracks on the West Coast for a certain kind of racing. This is not the raceway. This is the Stony Gorge Reservoir, but uh that's Elk Creek that bleeds into that. And we are looking kind of towards the north and the east.

[00:14:31]Um that's it's not far from the sites reservoir. So that's Willows. And it makes sense. It was named for the willow trees. It was Willows was as a lot of the towns which I really didn't understand as well because I always think of the railroads as coming from east to west. But when the Southern Pacific Railroad came in, which I believe went from Texas into California, the Southern Pacific, and went up California, that created this because most of the, you know, the, you know, like um the towns were founded on the big road, the east west railroads, but the southern railroad went in and that lot of little towns, I think it was in the late 1800s, a lot of little towns popped up and Willows was one of them.

[00:15:12]Willows one. Southern Pacific get gets a lot of heat for being kind of part of that the octopus thing or a main part of it. Uh in terms of just crushing farmers and and and being unfair, I guess. This is Mount Diablo looking towards San Francisco. San Francisco today 62.

[00:15:32]Uh the fog I don't think it's going to it's going to get back to the coast, but it doesn't look like it's we're far enough south that that lows should keep the fog. the the low should shouldn't have too much of an impact on the inversion. So the inversion will stay in place. Further north, the inversion is being lifted, right? And that's why the fog's eroding, but down in this area, the inversion is being increased. So that's San Francisco today. San Francisco Bay area. Today is going to be lots of mid 80s, upper 80s and some low low maybe some low 90s out in conquered and Walnut Creek. Yeah, probably some low 90s. Sites Reservoir just cool landscape. Um looking towards out towards Willows Maxwell area. Uh and then air quality check. Air quality.

[00:16:16]What are you going to think? You know, it's it's not going to be that great further south, right? But you got enough of that low in this area that the the inversion a little bit deeper. And the deeper inversion promotes better air quality because you're not right. You're not breathing this thing I showed you here. All this oops sorry.

[00:16:38]all this lifted and it's not the it doesn't save you completely, but that's a deep marine layer. You can tell because it's so far inland. Well, that that this is when in tight inversion the there's that's how much air you got to release emittance and pollutants into.

[00:16:52]And so, you're kind of breathing it. But when you do that like this, it's the deeper marine layer and still intact.

[00:16:58]You still have not great air quality, but you're mixing it. There's there is some mixing. There's more room for the junk to spread out, so it's not as concentrated. if that is a okay explanation and you can see here that would represent that this is out towards um where we're kind of out towards fire looking towards fireball actually we're looking a little bit towards the north so that would be up more closer to Modesto area but the central valley classic central valley and you can see the cirrus clouds they're kind of out of the mix today this is Bakersfield we put a loop on it and you can see that haze that comes up in the mornings often in times. Get another hit of coffee.

[00:17:45]That's kind of cool. I love classic that classic valley landscape.

[00:17:50]Camera's moving a little bit. So, there's a little bit of wind. We do have wind advisories in Northeast California.

[00:17:55]Um Fresno today, Bakersville today. 100° 101 degrees. Um yeah, 101 100 101 degrees is what they're calling down there. So, and let's see how the air quality looks down there. How'd it look to you? Let's see. Let me look at it again. Looks kind of sketched, doesn't it? It's It's not Yeah, not great. Not horrible. LA's got some junk today. Not great, though. Okay.

[00:18:19]And then this is um down towards Santa Barbara. Actually, this is the Channel Islands here kind of above LCAP. If you know that on Highway 1, LCAP's down in here somewhere. That's again showing the inversion. kind of a little bit shallower. We're at uh how high up are we? We're at 4,000 ft. So, the inversions around Yeah, it's pretty deep. It's 1,800 feet or so, but that's a Channel Islands out here. Um Santa Barbara down here and huge aggressive marine layer right there. This is Pasadena with a pole in the way.

[00:18:55]Pasadena today is going to go well LA today is going to go 69. Pasadena is going to go 77.

[00:19:00]And you can kind of see the I push this this way.

[00:19:05]See what we got. Oh, yeah. And then we're looking down towards uh we're looking south.

[00:19:10]Yeah, there's LA out there. So, that's a pretty, you know, that's a robust marine layer for sure. It's a little deeper than normal, maybe 1,800 ft. We are at 3,000 ft in this shot. Let's see what the air quality looks like in LA. I We already kind of saw it. It's typical morning. really got to realize a lot of this is is smoke and junk from the morning commute. It's kind of stuck in that inversion that lo that basin that Los Angeles basin and this one when the people talk about that's what they're talking about this basin. This this this area that is just ringed by mountains.

[00:19:45]Cool air comes down in the morning. Cool air from the coast and creates an inversion. Cold air under warm air and the junk gets caught in. And this is a large basin. You know, think about you San Francisco Bay Area. A lot of us, everybody's got a not everybody, but a lot of topography, especially in the coastal regions, has have these kinds of basins, but they're small. They're not that big. This thing is massive. And so, it has an opportunity to get a lot of less or a lot more nasty aquatic, not just because of the basin, but because you've got millions and millions of cars driving around. This is uh looking towards Let's see what I got this. Oh, this is down towards San Diego. This is looking to the south towards I believe Oceanside and I can put a loop on it here. This is sort of Let's see what that looks like.

[00:20:38]That's going to be interesting. But you can see so you're looking at the towards kind of towards the coast and you can see the fog kind of go wafting back and forth. Isn't that awesome? Come on.

[00:20:52]Those waves. Isn't that interesting? You wonder what the h I'm going to speculate. I mean, I know what I have an idea what I think it is.

[00:21:02]Okay, so these are the highs from today for today.

[00:21:06]Uh 91 down towards, you know, down towards Bakersfield or 101 in Bakersfield, 91 down towards Gorman, uh in C cassidas. Uh Los Angeles, 69 degrees, 104 in the deserts of California, 62 in San Francisco. Today is another warm day, but not as. And then tomorrow, watch this. Boom. Color.

[00:21:30]Just look at the colors. Today, tomorrow. And that's that low. That's This is weather. This is all weather is you guys. Pattern recognition. So there's the low right there. And that low, even though it's still a day away, is going to have significant impacts on the um temperatures. And that's that's the mechanism right there. Plus that chance of rain. In the winter, this would probably be a potential rain event, but it's not the winter. Okay.

[00:22:01]And then the satellite loop. There we go. And what do you see? Anything? You see the storms down here? This is that's all active weather. We'll see that. And this is an active trough right here. This is our active trough right here. You see you can see all that. See the rotation. So this is all the active weather.

[00:22:22]lows low here.

[00:22:25]There's actually a low down here, too.

[00:22:28]So, that's those are the active weathers when you look at enough of these satellite maps. There's actually something here, too. See the rotation?

[00:22:35]Just a weak rotation. So, um you get used to looking at. So, when you look at a weather map, you go, "Oh, yeah. That's where the stuff is." And you'll see in the east, there's not a lot of severe weather warnings. There's some flood watches and such. This is fire stuff in the Dakotas. This is wind and fire stuff. Wind. A lot of wind. I wonder what the wind why there's wind. I think I know why. Right. Most likely the wind is there's a pressure gradient. This is a low pressure here when we were watching. This is a higher pressure here. So the pressure flows from low to high. So it simply you've got a pressure differential between that low and this high. And that, oh look, all the wind activity. Orange represents heat advisory, wind advisory up in northeast California up by Sierraville and Pyramid Lake area. It doesn't look like the winds are going to be crazy out of control, but it's going to be breezy. As Ocean Beach, foggy, which we would expect when we saw how far inland the fog went. This is the there's the fog footprint.

[00:23:44]And this is what it looks like at the beach.

[00:23:48]So when you go I always tell people because people it's funny I guess now it's not in the old days people didn't know when to go to the beach and I don't know if it's foggy I'm like well pull a visible satellite map you can see it right and that so that's what that that's what this looks like I know it's simple but it's it does bear rem reminding and sometimes I'll do it just to see to refresh myself on satellite footprint this is how it looks okay right it's simple and actual how it looks because satellite footprints are uh and radar footprints too are um they move they they're they they kind of have you have to interpret them based on topography and other things. So there is um San Francisco. This is Halama. I saw a couple guys out earlier. And you can see the fog. We already looked at the fog in Halama, right? Pretty good dose of it as well. The coast is ringed in with fog.

[00:24:44]And then all the way down to Carl's bad.

[00:24:46]Watch out for that dog.

[00:24:50]Dude, what's with the Labberoodles, man?

[00:24:52]Jesus. God. Ever since CO, I think that's a Labradoodle. I They're cool, but there's a lot of Labradoodles.

[00:25:01]It just became the flavor of the month.

[00:25:04]And now my my whole neighborhood's labrious and and I again dad's a vetinarian. I love animals. You love animals. But if you can, and I don't know why you can't adopt an animal like because one of the things we didn't when I was growing up, I worked in the can my dad's kennels and the there's a lot of animals that you know need homes and they're awesome like they know like sometimes bred animals are have a tendency can be not as robust physically because they haven't they don't have all the inputs all the um you natural um stuff to fight off diseases and that's why you see sort of exotic diseases with animals that have a tendency to be bred. Again, that's about as deep as my veterary science goes, but I just and now Labradors are awesome dogs, don't get me wrong, but if you can maybe let's say you got a Labradoodle, maybe you let's get another dog. Okay, next dog. Go to the shelter or go to the shelter and get I've never gotten any.

[00:26:06]I've never had a pet anywhere but from the shelter. And um I uh and they're all Casey, Carl, Sam's a cat, I got Francis now. Um this is Hemet I love this dude. Here's the thing about skating real quick. God, sorry. He skatepark, which I think is unique. Live camera. Temperature in Hemet today is going to be in the in the 80s. Um, I uh what was I gonna say? I lost my train of thought. Pets, Sam, Carl. Lost my train of thought. It was a great thought though. This gu can skate. Oh, I know. I was going to say about skaters. Um, like, see this guy, he's on his own by himself. He's skaters are they get a lot of heat, but they work really hard. When you see a skater do a kick flip, you got to understand that's thousands of hours at what this guy's doing and nobody and he's, you know, nobody cares. Nobody, he's just doing it, doing it, doing it, doing. So, when I see skaters, I see a persistence that's pretty like, see, and he'll go back and try that trick a thousand times. And to me, it's not. Surfing is a little lot different, but skating the skaters and they get a wrap for being just kind of whatever, like, yo, skateboarders kind of does. It's weird.

[00:27:29]always has or not always but and maybe some of it was deserved but in terms of persistence which is what life is about skaters this is um not what I wanted I think this is who are we bore on webcam let's do it anyway I wanted to show you the snow yeah skaters right this is um I think this is snow cam okay I'll try it again tomorrow. These are the birds near the end of the nest. It looks like they're trying to get in a little bit of shade, aren't they? Yeah, I think that's what's going on there. There's a little shade. So, they found the corner.

[00:28:09]There's the hunker down against the corner of the nest. It's breezy down in Big Bear. You can see the tree. If you look really closely, you can see the tree moving. It's going to be hot again.

[00:28:20]So, they're getting ready for another hot day. And it's interesting. You really think about that. You know, I never really thought about the heat in birds, but I don't know how they cool themselves. I could Google it, but I'm not going to. But you will tell me. Um, I imagine they're like dogs, right?

[00:28:35]Because they're not sweating. So, that's why Jackie's mouth open when it gets hot. So, we'll see. Birds are doing pretty good. And then Venice Beach. I see that. We see that guy before riding the bike. I've seen him before. Um, and the chair is not there. There's there's a couple of adopted dogs right there. How do I know? Because I know brother and sister.

[00:29:00]Um yeah, pets. They're awesome. That's the best thing about co is how I'm running out of time. Is how people got into animals, right? And you know, now we all know how awesome they are. Okay, I'll talk to you soon.
