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.

Aaaaaaaand I slept through the squall line because I chose the best time to have a throbbing migraine. 62/42 at IAD now.

Currently 70/57 at KIAD.

@losetoa6 Record Highs for January 11th: DCA: 75F / 1975 BWI: 73F / 1975 And in case you're curious... IAD: 71F / 1975

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?

The BEST time ... It should be back shortly. ETA: Around 12:00pm cst according to them via twitter.

Flurries started 5 minutes ago in Herndon, VA.

IYBY?! Are any pigs flying yet? In all seriousness congrats. Currently 40/23 at IAD at 10:57am est on Tuesday, January 7th, 2020.

Good point. Meanwhile 31/22 at IAD as of 8:27am est on Tuesday January 7th (not 8th!), 2020.

What is the estimated diameter of the flakes IYBY you'd say?

Let me see... I'd be very happy with a quick hitting 20" storm with extreme snowfall rates with lightning/thunder. I'd also be very happy to have 10 snow squalls that quickly drop 2" each within a half-hour with lightning/thunder and strong gusty winds. Even better would be a Quebec polar vortex/ strongly +PNA pattern bringing 4 particularly intense snow squalls that each drop 5" in a very short amount of time... with lightning/thunder and severe wind gusts.

Over 3"/hr liquid equivalent rates meaning snowfall rates of as much as 30"+/hr?! Me thinks this will have RDMs glacier experience beat bigly! I'm so far in that I'm actually now trapped inside and don't even know whether I can get back out. It's strange and dark in here with faint clouds of what look like memories or hypothetical fantasies of Armaggeddon-like storms crushing my neighborhood? Should I call 911? Will they even be able to reach me here? I've heard of a strange phenomenon that can sometimes occur when snowfall rates get very heavy. People say that the sky will flash (kind of like a camera flash) with either the color white, pink or sometimes even blue. They will then hear a crashing noise usually a couple seconds later... but in some cases within that second and loud. I hear of this happening quite a bit with lake-effect snow squalls from the Great Lakes. I've never experienced this phenomenon in person but it certainly sounds cool and unique. What exactly do you call this phenomenon and do we at least have the slightest chance ( at least a 1 in 100 chance) of seeing this phenomenon occur somewhere within this region if we can get strong enough lift tomorrow?

Funny... I had a similar conversation with my friend last night about Tuesday.
