32F with rain and 0.04" of ice accretion on the trees.

DC, Maryland, Virginia.

Snow started just after 6:05am and became moderate/heavy within ten minutes. Fine small flakes. It's tapering off now. Herndon, VA.

There is the potential for some ice accretion.

IAD just gusted to 44kts.

Yes.

I thought we had a coastal that looked like this in late January 2017 with a very similar setup that did indeed end up being all rain. I may have the year wrong though. Monday January 23, 2017. It was the one year anniversary of the 2016 blizzard and there was moderate to heavy rain with fairly strong winds through the first half of the day. Far NW areas changed over to frozen (mainly sleet iirc) and got some minor accumulations. And also, yeah, I remember a NWS disco out of ME or New England with very "irritated sounding" wording about it being late January that year yet not being able to get much in the way of any snow. ETA: Could have sworn I was in banter... sorry about that.

Yes. Around midnight last night the visibility here in my neighborhood in Herndon, VA dropped to near Valentine's Day 2015 snow squall levels.

Yes. The same thing happened with the early January 2018 ice event right after the coastal scraper and following cold wave that kicked off the year. Ice accretion all over the driveway at 33+F. Quite fascinating indeed.

The run wasn't sufficiently cold.

It’s certainly not as efficient, but it can still be ugly when the antecedent conditions leading in are pretty cold. A lot of the surfaces will remain solidly below freezing despite air temp being at freezing. Urban areas will have a harder time with accretion, but out to the north and west, it’s probably closer to 30 and really ugly Yeap. 0.03" of ice actually managed to accrete on tree branches at 32F with light rain/drizzle IMBY through the afternoon and evening following the nearly 5" of snow earlier in the day. This was the February 20th, 2019 event.

Sorry about that. In all seriousness though: So it's not just me. Good... Well not good but you get what I'm saying.

Yeah. That 2/11-12/2006 storm was a mashed potato boogie woogie.

This. I've noticed that since 2017, January 12th just wants to be near 70F in the region... other than last year's reprieve of course.

Aaaaaaaand I slept through the squall line because I chose the best time to have a throbbing migraine... it was even interfering with me watching 'The Rise of Skywalker' with my brother yesterday evening. It was a good movie though.

I love the farmer just guarding his turf. Farmer: *Points pitch-fork at the tornado* "FREEZE you diseased rhinoceros pizzle!!"

A category 5 hurricane up the Potomac and dead over my house?! Paging @Bob Chill. Oh yeah!! Uh huh!! Oh yeah!! Uh huh!! Oh yeah!!

Over how many minutes did you receive that inch?
