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. 

Thanks bud. Wasn’t sure. I’d take .8” sleet with a couple inches on top.
You think you’ll get to 18”?  From mesos I think you’ll be right close.

How is the surface low track looking in real time?
How soon could the LSV go back to snow as the coastal low further develops & heads northeast?

Mesoanalysis has the low roughly on the southern tip of the Delmarva currently. So track doesn't look to end up as far NW as some models had it but the models like the Euro and especially NAM got the stronger warm nose aloft correct. I was def thinking mix in southern York/Lancaster but didn't think it'd get as far north as it did. That tremendous 850mb fetch likely had a big hand in that. 

I'd say things will probably get changed over once heavier precip starts shifting back into the Sus Valley (and also comes up from the SW by looks of the LWX radar). Likely within the next couple hours.

About the big accident:. I see at Weather.com that there's a headline about it and some other accidents.  

"Pennsylvania State Police spokesman Cpl. Brent Miller said the incident happened around 3:05 p.m. on Interstate 80 westbound near mile marker 183 in Clinton County.

“It involved 30 to 60 vehicles with multiple injuries and right now there are two fatalities," Miller told weather.com in a phone interview at around 7:30 p.m. EST.

Rescuers were still on the scene and Miller said the number of casualties could rise."

Nice! I lived in DuBois for several years and still go back several times a year to visit family and friends. It has been quite some time since Clearfield/Jefferson counties have been hit really well.

Before the weenie suicides start, keep in mind this is a mid-december storm -- certainly atypical. At least over the past few decades when big storms tended to happen Mid-Jan to early March

No suicide weenie here. This is and will be better than last year already. We aren't the MA forum so no worries. We just have the good passion.
