California Weather: June 15th Update!

[00:00:00]Hey everybody, Michael Snyder, California weather watch. Today is June 15th. It's the first day of monsoon season here in the southwest USA. And we in fact do have some monsoon moisture up across portions of Arizona. So you may hear me mention this at times when it's affecting the state of California, especially over the next few months. It goes on through about September 30th.

[00:00:20]And it's generally a seasonal reversal and atmospheric low-level circulations.

[00:00:25]So when you got this ridge out here, the the flow is clockwise around this ridge of high pressure here. As you can imagine, you bring up more of a southerntherly flow back up into the southwest USA around that ridge. That's just one aspect of the monsoon there.

[00:00:39]And yeah, we will be talking about this over the next few months as it does affect portions of California, especially as I mentioned. Now, taking a look here, you can see that we do have some thunderstorms ongoing. Some of those up into Baja there as well. And we've got some above normal moisture into portions of southeast California.

[00:00:55]So if you feel a little bit muggy out there, that's probably the reason why.

[00:00:58]And if we scroll back through yesterday, I also want to mention here that I've been talking about this the last couple of days that some of the thunderstorms across the Sierra Nevada and we did have a pretty active day yesterday. Look at all those hundreds of lightning strikes there. And then we go through sunset and then they die off. The dal heating, you know, starts to fade away there as we go through the evening hours and come back out towards this morning. And again, there's some of that monsoon moisture bubbling down towards Arizona. Now, as of right now, you can see we got a pretty intrusive marine there up into Monterey Bay, the Bay Area, all the way up the coastline there as well. But once you get inland, we are pretty cloud-free across much of the state. So, looking at our overall pattern here, 500 millibars, approximately 18,000 ft up in our atmosphere, mid- levels of our atmosphere, gives us a good idea of where troughs and ridges are. You see this trough way out here, south of the Illutian Islands, we got this ridge kind of extended up into the Pacific Northwest off our coastline. We'll put that into motion. And as you can see, we don't have much in the way here through Tuesday. As far as troughs are concerned, the ridge is still out there.

[00:01:55]Things do start to change a little bit here as we go towards the end of the week. We do get a trough kind of swinging through here. And you can see that lowers the heights and that'll cool us down here along the west coast of North America. So, we'll be watching that one. I'll show you some of the temperatures on that here in a moment.

[00:02:08]And then you can kind of see another ridge trying to sneak in there as we go through the end of the weekend. So, I mentioned that monsoon moisture as well, precipitable water anomaly. Again, you can kind of see how it is above normal right now across some of the southwest.

[00:02:21]Not full-fledged monsoon season stuff yet, but again, it officially starts here on June 15th today. And as we scroll through towards the end of the week, you'll notice that trough kind of swing through there and then some drier than normal air starts to kick any of that monsoon moisture back down towards the Sierra Madre and off to the east.

[00:02:39]Now looking at the RRFS high resolution model, I've got the clouds overlaid here as well. And so if we scroll to where we are right about now, what is it right there? And you can see the marine layer along the coastline. And again, those thunderstorms is picking up on those pretty good across portions of Arizona.

[00:02:54]We'll scroll through the day today. You can see we do get a couple of storms pop off. Maybe the central Sierra Nevada here as well down into Baja. And I can't tell. Yeah, it does look like a few showers do pop off. Maybe San Louis Bispo County here, maybe Nevada down towards St. George and Utah and portions of Arizona. Then you can kind of see that move through as we go through tomorrow. Let's see what tomorrow brings. It does kick a couple of showers off here. The peninsula range down into Baja there also. And let's see the Sierra Nevada maybe just a stray stray shower. Looks like lesser coverage versus yesterday and probably what's going to happen there today. So if you guys want your own affordable home weather stations, got a lightning detection system with it here. So when the monsoon thunderstorms get going, you'll know just how far away they are from your house. Got a haptic rain gauge, ultrasonic animometer, all kinds of stuff here. Very fun weather station.

[00:03:42]Click on that link down below to save 10%. So taking a look around uh Sacramento Valley here, you can see again another very hot day here today.

[00:03:50]Look at Reading 109. A little bit of a cool down tomorrow, but you'll start to feel that especially as we get towards the end of the week as that trough swings through. Temperatures dropping up perhaps 20°. Sacramento dropping down as well. So much more comfortable there Friday and Saturday versus the heat we are still getting. You can see Sacramento at 95, Stockton 95 there as well. But Vakavville by the time we get towards Friday, 79° and also I wanted to mention this. This has been extended through Thursday morning. The beach hazard statements, watch out for those increased risk of sneaker waves and rip currents out there. Don't turn your back on the ocean. Be careful. I know a lot of people are at the coastline here this time of year. So again, that goes through Thursday morning. Same thing for Los Angeles National Weather Service, especially combined with the high tides here and some of this elevated wave action. Be careful. I mean, you got so many people down at the coastline. Not everybody's going to get the message here, but hopefully enough people do that where we can keep people out of trouble. Uh, nothing going on here across the Northeast Pacific Ocean as of right now. Just a slight chance of tropical cycle formation that is no threat to the Southwest USA at this point. Now, daily 2 meter maximum temperature. This is Monday, June 15th.

[00:04:56]This is today. And again, we're probably topping out 115 or so for Death Valley.

[00:05:01]And very warm temperatures out there, mainly the salt and sea, 110°. We're talking about Palm Springs, probably 108 or something like that. And then you've got some pretty warm temperatures once you get away from the coastline for Southern California, the Bay Area as well. And again, Sacramento Valley towards Reading topping out 108, 109 today. And some of the interior valleys once you get away from the immediate coast up into Northern California as well. Very hot here today. Now, we cool down slightly tomorrow and even a bit more Wednesday. And then Thursday, look at that, dropping the temperatures down by the time we get towards Friday.

[00:05:30]Again, dropping down quite a bit here.

[00:05:32]So, much more comfortable conditions and that trough swings through and then maybe starting to bounce back there as we go through next week, but not quite as hot as what we've been dealing with here the last few days. Uh, this is a running 7-day total of temperatures. And we're just going to kind of scroll through this. You can see interior portions some of the Sacramento Valley and Sacramento and actually below normal here, but much of the state still kind of engulfed in this above normal temperature uh regime here as we go on in towards the end of the month here.

[00:05:58]Coastal areas kind of staying much closer towards normal there. And again, the Bay Area kind of right at or below normal for many locations. Uh total precipitation in inches. I wish I had more something funner to show on this, but this kind of that thunderstorm regime across the Sierra Nevada as we go through this month and not much else here showing up for the state of California. And we'll continue to watch that. That can still change of course when you're looking this far out in the forecast. There's the 6 to 10 day above normal temperatures here up and down the west coast and the below normal conditions. It's kind of clipping Northern California there as well. This goes to June 24th.
