I've got "bright news" and "dim news", kinda like good news / bad news...on the bright side, as of tonight, sunsets are after 9pm until mid-July!! On the dim side, it's gonna be cold and damp the next few days (and nights).

Tomorrow (Friday) looks pretty benign - cloudy, scattered showers, afternoon highs only in the low-60s.

Saturday is shaping up to be a bit of an interesting day, in two noticeable ways: afternoon highs probably won't break out of the upper-50s; and there's a decent chance of thunderstorms midday into the evening. Wherever they pop up, they could bring lightning, heavier downpours, small hail, and gusty winds - get indoors if you hear thunder nearby! They'll be moving roughly west-to-east, so keep an eye on the sky towards Seattle and Bellevue if you're outside.

Sunday, things calm down a bit...afternoon high temps bounce back into the mid-60s, and while we'll stay mostly cloudy, there's only a slight chance of an afternoon shower. Looking a bit further into next week - another system comes through with some showers early in the week, before we look to dry out and warm up by the end of the week.

It's June 1st - today marks the start of meteorological summer! For stats and record-keeping purposes, it's easier to use the first of the month rather than the solstice or equinox dates, which aren't always the same year-to-year.

Tomorrow (Tuesday) will definitely feel like summer - afternoon highs in the upper-80s, though touching 90º isn't completely out of the question. The air will feel pretty dry - not quite Arizona-dry, but let's still call it "nose bleed weather". However, that also means an increase in fire danger across the entire area.

The heat is short-lived - Wednesday and Thursday drop back to the upper-60s to low-70s, before we knock another 10 degrees off Friday and Saturday, closer to 60º both days. Chance of showers return Wednesday, before a better chance in the Friday/Saturday timeframe. On the bright side, we've had worse "June-uary" weather before - I'll take it!

Thursday morning update: A *slight* chance of thunderstorms late this evening across Western Washington...honestly not expecting much activity, aside from some overnight showers - though the rain could be heavier at times, and can't rule out a few lightning strikes. If things changes as the afternoon and evening goes on, I'll keep you posted! Until then, it'll be a pretty gorgeous day - afternoon highs near 80º! Clouds will start to build later this afternoon into the evening, but we'll stay mostly sunny until then.

Normally I wouldn't make a big deal about these types of storm setups, aside from a quick mention - but it *does* look like it might meet "severe storm" criteria in Eastern Washington and Oregon this afternoon and this evening. If you've got friends or family over there, make sure they're aware - main threats looks to be strong winds and decent-sized hail!

Tomorrow (Friday) still looks cool and showery, though no thunderstorm chances. We'll start to bounce back thru the weekend - partly sunny and low- to mid-60s by Saturday, partly- to mostly-sunny and mid- to upper-60s on Sunday.

05/26/2026

It's the last week of May, though today felt a bit like "June-uary" - and the next couple days will too!

After the main band of rain *finally* moved through late this afternoon, it's left us with the chance of scattered showers thru tomorrow (Tuesday). Not expecting more than a few hundredths...enough to wet the ground, if anything. One more day of temps on the chilly side - low-60s tomorrow too.

A temporary bounce back in temps Wednesday and Thursday - back into the low- to mid-70s on Wednesday, and possibly even 80s on Thursday! The warmth is short-lived though, as another system takes a swing at the PNW by Friday...shower chances reappear, and temps look to drop back into the 60s again. This is actually pretty normal for this time of year - we've been spoiled the past several weeks with more summer-like weather!

Monday morning update: plan on a cool, wet, breezy Memorial Day.

The main rain band is already moving across the Olympic Peninsula, and should move towards the Plateau around lunchtime…it’ll be pretty steady rain thru the afternoon and into the evening. Once it moves through, we’ll just have scattered showers thru tomorrow in its wake. It’ll also be a tad breezy thru the afternoon too - nothing too strong, strongest gusts only in the 20mph range. As for temps - we might eke out a couple more degrees this morning, bumping us to the low-60s for our “official high temp” of the day…but once the rain starts falling, so too will the temps, right back down to the mid- to upper-50s.

Back later with a look at the week ahead!

05/22/2026

Like most holiday weekends in the PNW, don’t think we’re gonna get thru the whole time without some rain…but at least it’ll wait until later on Monday!

But first, I want to apologize to everyone for not giving you an advanced notice of the snowfall this week. The cottonwood is *horrible* this year!! We went to Jobo’s for dinner last night, and it felt like we were stepping thru small snowdrifts in the parking lot!

Today (Friday) will probably be the best of the long weekend - mostly sunny, afternoon highs in the mid- to upper-70s! Saturday and Sunday stay dry, but a tad cooler - only low- to mid-70s. They’ll be the “morning clouds, afternoon sun”-kind of days too - and it might take the clouds longer to burn off than normal, so might be “late afternoon sun” instead.

The next weather system arrives on Monday - at this point, it looks like the showers hold off until the afternoon, leaving us with a dry morning…but we’ll see what it’s looking like as it gets closer. What we do know is it’ll be cloudier and much cooler - afternoon highs only around 60° or so.

Enjoy the weekend!

Friday late-morning update: cool, showery, and a chance of afternoon / evening thunderstorms today and tomorrow. Afternoon highs will struggle to make it out of the low-50s - some snow is even expected in the Cascade passes! Down here, it’ll be a drippy couple days, around a half-inch of precip or so…though we could get some heavier showers if a convergence zone sets up. There is a chance of some thunderstorms across Western Washington thru Sunday - though we’ll just have to keep an eye out to see where they pop up!

05/13/2026

Tuesday 9pm update: cells are starting to pop off to our south, moving north towards King County. They’ll fill in over the next few hours - very likely we’ll get some rain overnight (could be heavy at times), though a smaller chance for lightning…but still possible!

Tomorrow (Wednesday) will be roughly 20° cooler than today - might want to break out a sweatshirt!

05/12/2026

Tuesday 12:45pm update: some scattered showers are streaming north! Definitely felt a bit muggier outside recently…this should help!

05/12/2026

As beautiful as the weather's been recently, we've gone a couple weeks without rain...thankfully, that's about to change!

But first, one more warm day. Tuesday will get into the mid-80s by the afternoon! The air might feel a little muggier as the day goes on too - that's the early signal of a system that'll scoot through from the south, bringing some showers late evening into the overnight hours...and a thunderstorm or two isn't out of the question either. I'll be watching it as it develops over Oregon, and post updates tomorrow if it looks interesting!

Showers will continue Wednesday thru Friday - could be as much as 3/4 of an inch by Friday...(I just turned my sprinklers on tonight for the first time this season - I'm thinking that's kinda like getting a car wash...it's pretty much a slam dunk we'll get dumped on now. Sorry!) The other big story will be the noticeable cooldown - afternoon highs only in the low- to mid-60s...actually slightly-below normal for this time of year!

Back tomorrow with more updates!
