Sunday Feb 22 Snow Event (Or Nothing Event, Who Knows?)

[Anonymous]

I’m in Boston where they’re now forecasting blizzard conditions with 12-24” and 60mph+ wind gusts. Typically, scenarios like this aren’t kind to snow lovers in the DC area. I’d guess something like 1-2” for DC and west, with roads fully clear by Monday AM.

OP here.

I know, right? The temperature is the biggest uncertainty. It's impossible to predict accurately when the temp is marginal and hovering between freezing and above freezing. If temps stay above freezing, we'll get no accumulation. If temps dip just a smidge, and the inverted trough is positioned just so, then we can get as much as much as 8-10 inches in parts of the region. It's one of those storms...

Temps like that create ice/sleet and not snow. This could be snow-crete part 2

No and no. If ground temps are above freezing, the snow just melts on contact. There will be no snowcrete under any circumstance for this storm.

It's weird you don't understand that the last time we got snowcrete, it was because the ground and the air were well below freezing BEFORE AND AFTER the storm, and that the storm had hours of sleet because there was a warm layer sandwiched inside the cold airmass. The sleet froze rapidly on contact with the ground. It was wild, and has never happened in the 20+ years I've been living in the DC area. It's not likely to happen again any time soon since you need very unusual conditions, which usually do not verify for us.

Again. No snowcrete.

So what’s the forecast??? All rain?

Forecast is still all over the goddamned place.

1. All rain during the day, that's for nearly sure.

2. Then accumulating snow in the evening and throughout the night. It's anything from 2 inches to 7 inches. There's a coastal low, an inverted trough thingie from the west, and energy from Canada, and it's all mixing in unpredictable ways. The main thing is that it gives a nor'easter for NY and Boston, and the coast. And the DC area might or might not get pasted with heavy wet snow in the night of Sunday to Monday.

3. Which means, given there's accumulating snow during the night, and thus not enough time for plows to get to school properties, at least a delay on Monday, if not a closure.

Thanks for that! I assume any attempted pretreatment would just get washed away by hours of rain as well.

It’s Sunday morning and I’m not seeing more definite predictions for here. But I’m gathering it will be regular snow 6 inches or under? Still enough to stop things on Monday.

Forever. lets just stop all adulting. No work at the office, no errands, no doctors appts none of it.

Let’s let the robots do all the work. Wouldn’t it be great if we could each have our own robot and train it to be POA for everything we normally would do

While I typically hate the idea of AI and robots you're on to something here. If only they could do our medical appointments though.

The temps that create sleet are the ones up higher in the atmosphere, not at ground level.

Snueing hard. Grass and cars are white. My road was just treated and is fine.

lolol! gigantic nothing burger here in Alexandria.

I’m reporting 5 inches in my backyard in Olney

[Anonymous]

I’ve got 2-ish inches in Arlington, but it’s very wet and heavy and all the trees are bowing down. The risk for this one is trees coming down throughout the day.

Barely an inch here in Fairfax.
