Really, really lovely cumulonimbus action tonight! I just happened to have my drone in the car and got some solid shots of DT Seattle/Lake Washington/Mercer Island/Bellevue looking north from Skyway. Alas, the focal length of the lens doesn't do the vertical height justice and my WB was off rendering it into semi-gross HDR territory, but still... fun looking weather! It was quite windy- I was flying right at 390 ft and the drone was giving me all sorts of warnings about sustained winds/gusts. 

insta pin. glorious cloud pics!

A most incredible snow storm. At times the snowfall rates have been as heavy or slightly heavier than January 2017. Temp 27.5, Dewpoint: 27.1 with gusty east wind and very heavy snow continuing. I'm at 11 1/2" now! UNBELIEVABLE!!!! This pic does no justice at all.

AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA

NBM is quite an interesting product! Their weighting algorithm is moderately complex and dynamic, though does has some drawbacks as we saw yesterday. For those who don't know, NBM is an attempt by NOAA to create a super probabilistic forecast model that ingests output from all the models above and outputs forecast guidance for local offices that help them to gauge the relative odds of particular weather outcomes. The 'special sauce' is the post-processing, normalization and weighting that they d

WHAT an event. Huge overperformance for us at this location. Measured 5.5" of snow. Just incredible.

Makes me wonder: which Portland has received more snow so far this season? Maine or Oregon?

The one with the lobsters!

Portland, ME is on another level from the big Northeast metros when it comes to snow in the winter. Even though they're only 107 miles north of Boston it seems like a different world a lot of the time there. Kind of like going from PDX to Hood River or something.

Looking at the historic data, 1936-37 is the only winter on record where West Coast Portland beat East Coast Portland.

Trash weather. I’m not remotely acclimated and was sweating like a pig walking around campus the sun (as were many others, lol).

Would be a beautiful day by summer standards, but this simply does not belong in February. Period.

Yeah I’ve been sweating my balls off down here in Alabama. Hit 82 yesterday and Didn’t go below 66 this morning and it’s 77 right now. Dew point is also 71 so it feels like a swamp outside.

My area radiates well, so have had plenty of subfreezing lows locally. But DC proper is often 10+ degrees warmer at night vs this location. 😕 The difference never used to be that much.

Seems to be a pretty persistent theme for much of the Chesapeake region, I'm afraid. Those warming SST's are really doing their thing.

Hopefully you radiate to a decent temp on Saturday morning before the clouds pick up and give you a shot at a little snow.

PDX holding at 29. Probably one of their coldest afternoons on record for this late in the season. 29 here as well with brisk winds and full sunshine.

Fun to think what kind of temps they would have put up if this exact same setup had occurred a month or two ago.

Andrew?

Would be nice, though there could be too much wind to effectively decouple. If there’s any kind of W/NW wind we will remain well mixed.

Definitely true re: Chesapeake SSTs. Those waters regularly get into the 90s in Jul/Aug because they’re so shallow. Dewpoint machine.

Everything stops moving in early March. Impotent zonal momentum transports evident just by watching the loop.

OP is useless that far out.

For specifics of course. I’m looking at the bigger picture which appears (on its face) to be fairly similar across guidance.

How some of y’all drive I swear

 

 

I took this exit over and over again for years for the past 30 years. It's perfectly fine. There are advisory speeds posted everywhere prior to the exit at 30mph then 20mph. Dumb people be plowing through exits like they still on the freeway. 

The only complaint I have is that they can improved lighting under these tunnels.

You know what? **, actually. I flew up here because my mother is dying and she needs my help around the house right now. I am not going to leave my mom at home while I go drive to the other side of town to sit in a snowy Fred Meyer parking lot, what the ****.

I wanted to see some decent snow here because it would be a small silver lining during what is otherwise a very painful and difficult time for me and my family. My mom really likes snow too and I was hoping that this storm would be something that I could look back on fondly as one of the last happy memories I had with my mother. I am so very sorry that my disappointment is upsetting to you.

I'm sorry for that awful situation man, I really am, but how on Earth could he have possibly known that? You're throwing this out like a "gotcha" when in reality it really did look like you came up here for snow. Honestly this is an extremely toxic and unfair thing to say. But I'm sure you're in a lot of pain and didn't mean to cause any harm, I get it. You reached your breaking point... It happens.

Just for reference in case mods cruise through later and decide to ban me based on certain people’s reactions versus what actually happened, this is the truly awful post that caused all the trouble.

      April 2024 Weather in the PNW

      I think their 2" on August 24th 1992 is absoluetly f****** absurd. At least in June there is just enough residual wintertime cold left over at the poles to drop snow levels down to 5k feet should it be displaced south, and enough of a poleward thermal gradient still in tact to spawn strong-ish cutoff lows around the meridian line. Mid-late August is a joke of a time to get a snowstorm, even at their somewhat high elevation. They pretty much combined the strongest weather system possible at that time of year with the coldest air possible... Neither factors being very impressive nonetheless. But enough is enough. The only month I doubt they could pull off a snowstorm at all would be during July, and even then I bet the first week holds some out-there potential in the right setup. July 15-August 15 is off the table though. I think....

      April 24-29 Multi Day Central and Southern Plains Severe Weather Outbreak

      Pi-Day event had its interesting parts. Before the main bout of supercells in IN/OH, there was one lonely supercell that travelled from near Cincinatti all the way to my vicinity a few hours prior, with nothing else picking up on JKL radar around that time. Then all the later night storms developed into an MCS hitting me around 2am. Overall the Feb 28 and April 2 events gave me much more of a uh-oh feeling in the gut. Pi-Day had a ton of large hailers, and a few storms that happened to hold together a stronger tornado. Not to say 3/14 wasn't a good one though, Ohio was a surprise during that one as they weren't exactly bullzeyed at first.

      Polite Politics

      Oh, I think one side is just a bit more guilty of that than the other. Trump has taken the racist nationalist playbook and made it his platform. He is the GOP nominee and has a real chance at being the next president. No sane person can make that claim about the left and Biden (even if he is Netanyahu's little biatch). And I loathe what a lot of the left has become.
