This day in history: Doc Brown invents time travel

45 mph gust so far 💨 💨 Between 9pm-3 am there a good chance of cracking 50

East winds returning right on schedule. Already had a gust to 35 mph at ext. 32 I90 at 5 am. Winds due to an even stronger offshore Low (975 mb) than Saturday, but this one will stay further away, curling up well into BC. Expect about this intensity all day, until ~8pm.

Nice iridescent cloud over Lake WA this afternoon

First smoke sun of the season Sugarloaf fires near Wenathchee have really expanded AQ not expected to significantly improve until onshore flow and cooler moist air returns this weekend

Consecutive days at or above 90° after August 15th From previous records available at Snoqualmie Falls (records stopped in 2008) 1 8/22-26 2025 5 (days) 2 8/15-17 1927 3 3 8/24-26 1916 3 4 8/19-20 2004 2 5 9/2-9/3 1988 2

Update from WSDOT 1:45p "CANCELED: The five-day closure of State Route 18 scheduled for May 15-21 has been cancelled due to forecast rain. It will be rescheduled to a later date. " @wsdot.wa.gov

Looks like around 7pm things are going to get wild

The risk is low for >1" hail, but that risk is not zero Main timing for the convective outbreak to move northward to the Puget Sound region still looks to be ~6-8pm #wawx #convectiveoutbreak

Aircraft taking off to the north today. That means at least one more nice day. Uhh..make that exactly one more day. Rain returns Sunday. Enjoy the early spring while it lasts!😎

Felt that one! #waquakes

I90/SR18 station recorded 47 mph gust this am Our 9th windstorm (8 of 9 E winds) with a gust >=40 mph this fall/winter season, par for the course, but our 4th major power disruption which I believe is on the high side. First storm having southerly winds that strong this season.

Not out of woods yet. Peak gust potential remains through ~ noon. We've had max gust 37 mph at I90/SR18 xchange, and same out at ext 32 in North Bend, thus far relatively unscathed Out west, Boeing Field clocked a 60 mph gust. Outage map says it all re: strongest winds

Send in those weather station wind gust reports tonight/tomorrow am! #wawx

Another 3.5" (13" since last Sunday). This has been a perfect setup out here, nothing that buries us, but a good shot each day with no east winds drying out the air and knocking the beautiful snow off the trees.

Another 3" at HQ (~800ft.). 10" since Sun, surpassing last year's 5-yr low of 7" for the entirety of the 2023-24 season. Measurable snow before midnight Fri would be 6 days in a row, a new record since I started writing this stuff down in 2018.

Morning

Nice flakes, heavier wet snowfall

Well this is a good start! ❄️

😎

Cold and beautiful

That makes three!

Feel that?

Another windy night, should be past peak now 45 mph - North Bend (Ext 32 I90) 37 mph - Snoqualmie (Ext 25) 34 mph - Snoqualmie (MSHS)

In the near-term we have these east winds picking up strength Friday morning, peaking ~30-40 mph around 7 am. Ho-hum weather outlook otherwise. We're likely to remain above normal temperatures for this time of year.

No lowland snow for December. But all is not lost for snow fans. Jan and Feb can really deliver out here. #HappyNewYear2025

The wind threat has now turned from out of the south with brief surges of gusts ~50 mph possible through ~ 1 pm Overnight we had a max gust of 44 mph in North Bend and 41 mph in Snoqualmie

Rain increasing with one-two punch of howling winds tonight/early Thurs. Peak gusts, first out of east 35-45 mph overnight, then turning southerly after 7 am, those gusts to 50 mph possible until ~noon, but more likely that strong out on the Sound. Shouldn’t get any worse the rest of the year😉

If this isn't enough for you, winds are about to pick up a notch (~9pm-1am winds will be peaking) Top gust readings so far (9 pm): 50 mph - WSDOT Ext 32 (NB near River Bend) 48 mph - MSHS

Tomorrow's bomb cyclone shouldn't be quite the impact as the Nov edition: gust mph a bit lower, mountain wave chance lower, and trees been stress tested. New construction has not:( I hope everyone keeps their power. East wind potential 40+ mph even out to Bellevue. Not common.

Morning

Bomb Cyclone [December edition - sub 970mb] still on track for afternoon on the 23rd/early am 24th. Maybe 60+ mph in the foothills, 40+ mph Eastside

Another day, no shortage of wind Strong SE gusts are shifting to SW after ~6 am. Looking at the models, I would extend the wind advisory through noon. Scattered showers through morning, then we should dry out Wed afternoon, and maybe even eke out a dry Thurs(day) before showers return Thurs night.

Stormy Tuesday on tap. An atmospheric river slides into W. WA but rain totals looks to keep to around ~1" out here in the central foothills Wind and rain on the increase through the day. Peak easterly gusts 30-40 mph possible afternoon through early am Wednesday.

Frontal system will move in before the Monday am commute with lowered snow levels to ~1200-1500 ft. Be mindful if traveling over Tiger Mtn that could see some wet accumulations before drying out Monday afternoon. That system will briefly kick up the gap winds 25-35 mph Mon am.

Fri night wind: ~40 mph E gusts possible (~4pm to midnight, before tapering rapidly). S/SW winds Saturday am would be ~10 am-2pm, 25-35 mph. Rain on the increase tonight, and expect off and on showers through the first part of Sunday. The lower mountain passes should get some much needed snow.

E gusts 25-35 mph cont to ~6 am Thurs. Friday's east winds ~3pm - 3 am, max gusts a bit stronger ~30-40 mph. Not a lot of rain with either of these events. Similar pattern next week Looking further out to Christmas, not seeing much chance of lowland snow

Strong front inland overnight brings rainy and breezy most of weekend to lowlands. Also rainy at the Pass Saturday, but changing over to much needed snow Sunday, possibly enough to issue an advisory. We then build in a high pressure ridge again, for dry weather Monday through at least Tuesday

Change coming

This fair weather temperature inversion starting to take a toll on air quality in the lower elevations out west. Set to end late Friday for the weekend ☔️

Colorful lightning this afternoon #wawx

At 7:15 am Friday we're just about at peak E gusts, windy conditions expected through ~11 am. Peak gusts: MSHS 42 mph Ext 32 (North Bend) 40 mph Ext 25/SR18 (Snoq) 38 mph Covington 37 mph Enumclaw 42 mph (the epicenter of gap winds, hit 74 mph Tuesday)

Still good consensus round 2 remains well offshore and won't pose bigger problems. Thankfully, not looking like a repeat of Tuesday night.

NWS issued a Wind Advisory (lower threat than Warning) for 10 pm Thursday-10 am Friday, but as of now the stronger east winds (~40 mph Snoq-50 mph NB) look to be after 2-3 am. Not a repeat of Tuesday night.

At least it's easy breezy in the weather dept. for the remainder of today and Thursday. Another round of gaps winds in wee hours of Fri (peak gusts ~40 mph) but hopeful won't cause add'l issues. Further out, models back toying with idea of much colder air the weekend after Thanksgiving.

Power outages= some stale anemometers around here. Me thinks we breached 60 mph in the last hr tho. Peak gusts readings so far: Snoq. Ridge 55 mph (pws) I90/SR18 52 mph MSHS 49 mph (stale) Enumclaw 74 mph (down) Covington 54 mph Peak gusts between now and midnight, with a gradual taper to dawn.

Peak gusts so far (7:00p): Ext 32 (North Bend) 51 mph MSHS 49 mph Snoq. Ridge 46 mph Others locations: Enumclaw 74 mph! Covington 48 mph Not getting that big pull up here, still probably 2-4 hours to the worst of it though

Surprisingly not the wide swaths of outages out here yet.

Peak gusts so far (4:40p): MSHS 49 mph Snoq. Ridge 40 mph Ext 32 (North Bend) 40 mph Others locations: Enumclaw 49 mph Covington 42 mph We have so far to go😬

Mount Si HS --> 32 mph so far, just getting warmed up!
