Pacific NW Weather May 30th Update!

Hinzugefügt: 2026-06-01

[00:00:00]Hey everybody, Michael Snyder, Pacific Northwest Weather Watch. Today is May 30th and right now we are looking at the infrared/visible satellite imagery. I've stopped at about where we are here this morning. You can see there are kind of a mixed bag of clouds out there and we do have a system that's going to be setting up over Montana out there. It might try to wrap some moisture back around into Washington and maybe another system as we go on in through next week. But we are going to have a warm up in between that as well and we're going to get some nice days here across some of the region. We'll dive in all those details.

[00:00:31]We'll take a look at that extended forecast as we go through the video here this morning. And again, the visible satellite imagery. There are some active thunderstorms going on right now across some portions of South Central Montana as we speak. And a pretty nice state unfolding here for some of the region.

[00:00:48]Again, some nice sunny skies even for the Washington, some of a little bit of the Oregon coast here this morning also.

[00:00:54]Now, taking a look at where we are right about now, as of actually, let me update this. That has not been updated here today. It did not look right. And there we go. There's that upper level low that brought us our severe thunderstorm activity across some of the Pacific Northwest. And that is going to drift off towards the plains. It's also going to kind of hang out here. This upper level low is going to sit right over Montana. But you can also see we're building this ridge as we go on in through the early portion of next week.

[00:01:17]And we're going to get a a couple nice warm days here for some locations. Then we got another very weak system. You can kind of see that trough out across the Gulf of Alaska kind of lowering heights, returning the onshore flow, bringing back Mother Nature's air conditioning into the Pacific Northwest and then we'll see what's going to happen after that as you can kind of see the lowered heights off to our north and kind of a westerly zonal flow back into the region here. So, something to watch over the next few days. Now, take a look at precipitation and some of its timing.

[00:01:46]I'll put this into motion. And you can see again that upper level low not low is going to be hanging out for Montana pretty persistent and it's going to bring some nice precipitation amounts and you can see Washington, Oregon, British Columbia. Not too much going on here the next couple of days. But then it starts to wrap back around a little bit there as we go through the day on Monday. Trying to clip portions of eastern Washington, some of Idaho here as well as we warm up here through Tuesday. Then another very weak system moves through the area there as we go through next week. and we'll be watching that one coming up. Now, this is looking at just off the surface about 925 millibars or 2500 ft off the surface.

[00:02:23]And we got the onore flow ongoing here as we go through the day today.

[00:02:27]Tomorrow, we're now going through Sunday here. And then you'll notice we start to turn things offshore as we go through the day on Monday. Kind of see that northeasterly flow start to come across Pacific Northwest. You can see it become northerly across British Columbia, eastern Washington, Oregon, and then it even gets a bit more easterly after that. We're going to get some compressional heating, some warming as we go through the day Tuesday. And we'll show you the next slide. It'll kind of explain that a little bit better. And then you see the next week system out here start to try to swing through and kick the flow back onshore as we go on in through uh next week as well. So, this is about 5,000 ft, 850 mibars. If I put this into motion, this is below normal temperatures is what we're dealing with here today and tomorrow.

[00:03:11]And then we start to switch things up a little bit here as we go through Monday.

[00:03:16]You can see the offshore flow starting to return. And you can see the above normal temperatures at about 5,000 ft there. And as we go through Tuesday, you can see probably the maximum warmth there for places like Seattle, Portland, the lower mainland of British Columbia here on the day Tuesday as that upper low continues to spin just on the Canadian uh USA border there up into Alberta. And then we'll worry about that next system trying to slide in here and kicking our air conditioning back on. So this is hot off the press is the RRFS.

[00:03:47]So, if we look through the day today, again, you can see where the precipitation is over portions of Montana, some of eastern Idaho there as well. And as we go on in through the day tomorrow, looks like maybe a stray shower kind of clip in northeast Washington. But as we go through Monday, it starts to wrap back around towards northeast Washington a little bit. Might even kick off some showers towards the Cascades as we go through the day on Monday. So, we'll have to watch that one a little bit closer as we go through tomorrow as well. And then you can see the upper level low continuing to spin in right at the end of the run. 84 hours out. You can see our next system way off to the west there. Now this is the high temperatures here for today. But there is some sunshine peeking out there. So a pretty nice day here. Pretty comfortable. You know, mid60s for Seattle. There's some 70s out there, maybe 75 for Boise. If we put that into motion for Sunday, you can see slow gradual warmup. Monday even warmer.

[00:04:41]Pretty nice day there. Look at Portland.

[00:04:43]mid 80s, maybe an 80 degree reading across western Washington up into British Columbia. And then we go through Tuesday, probably the warmest day west of the Cascades. Look at that 90 maybe for Portland, Seattle, mid80s, maybe a 90°ree reading for Western Washington.

[00:04:57]And then we go through Wednesday, the onshore flow starts to return and we cool things down. Still a nice day here across the region. Overall, generally speaking, I mean, we're into the early portion of June. Our temperatures become much more comfortable at this time of year. And then we go through Friday, Saturday, Sunday. And again, we'll see how that works out there as we go through the extended. Now, this takes into account the recent rain we've received here. And we did bump up a few areas here. Some places didn't get much rainfall during this severe weather, like Ritzville, Washington, for example, didn't get any rainfall out of that, the dryland farmers out there. Um, but some areas did. And it is beneficial here, but it's not snow. And this is not really going to, you know, help out a lot as far as the drought is concerned, generally speaking. But it is a nice little reprieve here. And so far for the month of May, we're still kind of below normal here or actually fairly well below normal so far for the month of May and above normal in temperature. Uh this is the Palmer drought severity index here as well. This is through May 20th.

[00:05:56]So, we'll see if any of this recent precipitation kind of puts a dent in some of this, but you can see the Pacific Northwest largely speaking has been in uh very dry conditions. Now, the 15-day precipitation anomaly, kind of a mixed bag here. Oregon, Idaho versus Washington, and of course, Alberta and Montana. That system that's going to be spinning over them here over the next couple days is really going to, you know, bump up these anomalies here over the next 15 days. So there's a European artificial intelligence ensemble mean and maybe showing some of these systems trying to creep in here as we go through the first half of June. Here is the actual artificial intelligence control run. The initial conditions best we understand them driven out 15 days and you can kind of see that below normal signal kind of looming here as well. Now looking at the the European artificial intelligence. So we build that ridge as we go through next week. Then we start to try to bring that weak system through there and now this upper level low wants to drop down. Man, I hope this happens.

[00:06:50]This would be quite glorious. June 6th, but about the timing, June 5th or 6th.

[00:06:55]So, maybe some more active weather as we go through the first week of June. No promises just yet, but we'll continue to check back that on on that on a daily basis. And then a ridge tries to build after that. Who knows about that? We're looking a little bit too far out to get concerned about that just yet. But if we look at the European extended, this goes all the way through July 14th now. And you can clearly see this below normal signal kind of plaguing the Pacific Northwest. That's kind of what it's been showing here. And you know, we're almost into meteorological summer, which actually starts on June 1st. Just a couple more days to go before we are there. And looking at the temperature, this kind of a running 30-day outlook here. Uh 2 m temperature anomaly. You can see above normal across a lot of the inner mountain west extended into the Pacific Northwest a bit and below normal across some portions of British Columbia. If I extend that 30-day outlook all the way out into July, you can see that above normal substantially so there east of the mountains as well and some of western Washington. Now, this is the seasonal temperature outlook. This was issued May 21st, the latest from the Climate Prediction Center. You can see a pretty strong signal for above normal. This goes all the way through the summer on in through next fall and next winter with the the looming strong El Nino that will be most likely in place there across the equatorial Pacific Ocean. We are looking at above normal temperatures and the below normal signal is likely to be with us here across the Pacific Northwest.

[00:08:20]You might look at that and say, "What the heck is that thing here across the southwest USA and up into Utah and even kind of clipping some Idaho?" This is the the look of quite an active monsoon season here across some of the desert southwest. So, there you go. Below normal up here in that monsoon season.

[00:08:35]Maybe we'll get some a little bit of a taste of that monsoon moisture at some point as we go through this summer and bring some thunderstorms up here. Who knows? Um, check me out on Patreon.
