You all realize that any randos from outside the core board group might be reading this thread and think we are going to get a snowstorm today, right?

10z HRRR

A little Sleet mixed in with the rain in Hagerstown

I don't think you got the point he was making.

Set a record high of 81.0 degrees, old mark was 80 degrees from 1990. Crazy temp drop in last 3 hours, 35 degrees! Currently 39.9/35.0 with rain falling here at 8 am with NW winds 12 gusting to 20 mph. 

[dailylurker]

Still hot here. Windows are open. I'm trying to get that heat from yesterday out of the house. Bring on the rain/white rain. We need it.

[WVclimo]

Changeover happening here.  Sleet and some snowflakes mixing in.

[CAPE]

The 'less than a half inch' wording in the NWS forecast is about right- probably too generous in some locations. 

[Terpeast]

44 now

Edit 1 min later: make that 43

55 here at work. Was 70 when I got here 90 mins ago.

[wxdude64]

Looked around on cams, snow at usual places, 'Shoe, Canaan, Highland County, 95% of WV. Looks like snow line is around 1800-2000 feet elevation and falling fast around here.

That's exactly what I've received out here in sw Garrett County. Temp was 60.4 at midnight, now 29.1 - the yoyo party commences. Looks like I picked up nearly 1" of liquid in the past 24 hours which is nice. 

[LeesburgWx]

We still getting a snowstorm today?

Let's go over this for the third day in a row lol.

It's going to snow today. No weather model has any snow depth even in the coldest spots more than an inch or two. Most places will see a half an inch on grassy surfaces etc. maybe. Snow will come out of this sky but it won't amount to much. I just don't understand why there is any other conversation or any other maps.

[mitchnick]

Sleet has started to mix in imby.

EURO quietly had it's best run of the storm this morning. We'll see - even a slushy .1" at DCA would be a win. Good luck!
