@PrinceFrederickWx Lovin' it! I'd be very curious to see these same graphs over the past 100+ years... or since record keeping began at the local airports.

Is anyone going to try and see whether two dead satellites collide over Pittsburgh at 6:39pm est tonight? The chances of a collision are very low (1/20-1/100) but still... maybe we may see something if they do collide. They will be 560mi above Pittsburgh so you'd have to look up high.

That storm had a super deathband with crazy rates early in the morning of the 13th. Probably comparable to the Feb 1983 storm... nah that storm had 5"/hr rates according to some and the Feb 1979 storm had 4"-6"/hr rates.

@mappy I see that you're a @WxUSAF now.

A very cool story. Thank you for sharing. How was the Jan 25, 1985 whiteout at your location?... How much lightning and wind was there with that event?

He isn't. 49/40 with rain approaching.

Which of those rides most reminded you about storm-chasing?

You'll be forgiven and then some if you can bring us our Category 5 up the Potomac.

Close indeed. Just get a slightly stronger push of warm and humid air and it could be a nice high shear/low cape convective event for some. Still have over a week for it to trend better..... or worse.

I feel..... young-ish? I guess because I'm still fairly young-ish (early 20's) I get this preconceived notion that everyone who I haven't seen in person yet or who's general age I don't know is fairly close to my age. I think there are just two posters that I know of on here (from what they've said) who are actually younger than me. *shrugs* I know there are probably more people on here who are aob my age who just don't post much. Happy Martin Luther King Jr. Day.

Maybe we get our dues all at once? ...

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.

Total snow and sleet accumulations of up to one inch and ice accumulations of up to one tenth of an inch. * WHERE...Portions of central Maryland, northern and northwest Virginia and eastern West Virginia. * WHEN...From 7 AM to 7 PM EST Saturday. Precipitation will begin as snow before transitioning to sleet and freezing rain. Precipitation will change to rain late in the day. * IMPACTS...Plan on slippery road conditions. PRECAUTIONARY/PREPAREDNESS ACTIONS... Slow down and use caution while traveling. When venturing outside, watch your first few steps taken on steps, sidewalks, and driveways, which could be icy and slippery, increasing your risk of a fall and injury. && $$ Hope that helps.

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.
