Gravity waves?

Is that good for LSV to get snow rolling again, heavy precip, just some fun looking radar?

I had thunder in that band. It's really impressive!

I mean I hate to say it but doesn't surprise me. People drive like total morons in the snow...they think because they are in an SUV going the speedlimit is perfectly OK.

I can't tell you how many times on our local subreddit you get people complaining about slow drivers in the snow....just slow down and don't kill anyone. 

[Hoar_Frost]

Snow intensity is starting to increase again here.  

[Blizzard of 93]

The 23z HRRR has another 6 or 7 inches of snow tonight for the Harrisburg, Lancaster, & York areas, with even a little more in Cumberland & Perry counties.

Especially with the hospitals almost to complete capacity.

I agree just a matter of patience right now......between 1am and 4am rates should be heavy. I want this to change now, just gotta wait.

Oh I know I was one of the "assholes" driving 20-30mph on the way home from Carlisle today. Had plenty of people in pickup trucks swing out and pass me at 40-60 and then almost spin out as they hit drifts/piles from plows.

Checkout some of the SWPA penndot cams. First two cams I looked at one dude was spinning out off the road...another one a guy was stuck in the middle of an uphill bridge. The guy that was spinning out almost got hit by a pick up flying by him.

I'm impressed in how far the sleet got north. Looks like it's reached Route 22.

You and I both. Sleetin sideways over here. 

[Voyager]

According to my drone app, the temperature at 5,000ft dropped 2 degrees back to 30. Perhaps I may have dodged the sleet bullet?

Wonder how well it does with factoring sleet in? 

[paweather]

Sleetfest....Let's go column cool back down. 

[MAG5035]

7.6" and moderate snow. Waiting for that deform band to shift over just a little bit more. 

[Blizzard of 93]

@Eskimo Joe 

I just read some of your analysis in the Mid Atlantic thread on the possibility of changing back to snow in northern MD.

What are your thoughts for southern PA?

[2001kx]

Up to 10" now

[anotherman]

Looks like pixie dust here.

[jm1220]

State College with 9.5" from what I saw? Could be some really big amounts there with the band shifting east again. 18+ I'm thinking.

Didn't even think of that. A massive crash with 50 people needing to go to the hospital, especially in Clearfield county would collapse the system.

[basehore]

wowzer, haven't seen snow like this in my 4 years of living here....

up to 9 inches sn+ 19 degrees

Sorry, just saw a tweet from the PA state troopers about it, no article. I’d see if the State College media has anything - it was at the 180 interchange.

[paweather]

Band down in DC with the rotation over PA get ready for round 2.

WeatherBell doesn't include sleet in it's snow map like TT does. There's a separate accumulation map for sleet (using a 3:1) map. 

Which brings the question, does anyone have any noteworthy sleet accumulations to report? Typically I'll measure and clear when a transition occurs and measure the sleet separately.
