Snoqualmie Weather

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

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

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!

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!

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?

That rivals my father-in-law’s ham radio antenna 👍

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.

Ensos have some statistical significance for the mountains, but lowlands are more random. Snoqualmie Pass is actually well ahead of last year (acc. 126" vs 79" through Dec 31)

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

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😉
