Outdoor plans this weekend? I think you’ll be safe, but if you have any outdoor plans early next week…
Thursday – High 83°F, Low 61°F; Quite a bit warmer than anticipated, but who’s complaining? Mostly clear skies all day, with winds picking up late morning.
Friday – High 82°F; Mostly clear with a few extra clouds here and there. Wind has been mostly calm as well, picking up a little in the afternoon.
WARNINGS – Just a couple things for this batch. We have a Small Craft Advisory in effect for the Strait, and in the Cascades we have a Flash Flood Watch due to the thunderstorms moving in tonight. For more info, please see here.
Warm air will continue to dominate the skies, with the jet stream keeping the low to the north at bay. By Saturday it looks like the jet stream to the south (yes, there are multiple jet streams) will shift north a little, keeping the air warm, but that’s not what I’m keeping an eye on. There is a low out over the Pacific that looks to be on course to pay us a visit. By Sunday evening it will split off into two lows, with the southern one swinging in overnight. We’ll have a better idea of the timing below in the other models.
Pressure will stay fairly consistent through the weekend, staying on the high side of average. There will be a little bit of a pressure drop later on Sunday as the lows move in, but you can’t really see anything timing-wise. I will be skipping this model for today.
The mountains look to be getting a break now, as all of Saturday is staying dry. Sunday will be mostly dry as well, with a few showers popping up in the evening over the Olympics. You can’t really see the low on this model during the forecast period, but looking ahead, it looks like we won’t see rain until late Monday morning. I won’t be posting the model past the normal forecast time, but remember this: Monday is 3 days out from now, so the model can still change its mind on the timing. But it will rain on Monday. Even though there isn’t a whole lot of precipitation, I will still post the model because it looks like there’s a decent amount of CAPE Sunday evening. The showers in the Olympics could produce some thunder, but I doubt it.
No snow once again. After this week, the snow model will take the back seat until fall.
We’ll have some slightly increased cloud cover overnight, with some fog rolling Saturday morning. This should all clear out by late morning/early afternoon, and from there we’ll have mostly clear skies for the rest of the day. Sunday won’t have morning fog (and if it did, it’ll be very scattered), but we will see some high clouds for most of the day. Should still be sunny out though. Just a little hazy up high.
I won’t be posting the 24hr precipitation image because the Sunday showers in the Olympics occur after those images. So that should give you an idea of the timing.
Winds will continue to be about the same as the past few days. Calm for the first part of the day, picking up a little for the second half, with stronger speeds by and over the water. The only difference is on Sunday, where the stronger winds over the Sound will spread out a little more.
Temperatures won’t be as high as we’ve been seeing, but it will still be warmer than average. Highs on Saturday will be in the mid 70s, warmer to the south and cooler closer to the water. Lows will be in the mid 50s. Sunday will see the same temperatures, with mid to high 70s throughout the Sound this time.
TL;DR: Enjoy the sunny and warm weekend, because rain is on its way!
