I plotted it out graphically. Ouch. N 125 Mean 21.4 Median 21.7 Std. Dev 4.1

Assume no snow until overwhelming evidence proves otherwise is my mantra. 60 percent of the time... it works... every-time.

Got a sudden and rude awakening by the WEA from my NYE stupor. My guess is that there are going to be many an upset person after that one. Thankfully it didn’t awaken the wife. Patiently awaiting the squall.

Up-slope with diving mid-continent polar air masses are putting in the work. Pick the highest latitude / altitude combo.

Sugar grain snow? Doesn't look like dendrites.

The snow squall on Thursday pre-sunrise looks legit. Might have to set up an alarm for that one.

It's not in Thurmont. The station is at Camp David which is at nearly the highest point in the Catoctins. https://www.weather.gov/wrh/timeseries?site=KRSP

The front is fun. 10 deg drop in 8 min and a gust to 42 at Thurmont currently.

Yes, the hodographs, as taken by themselves, are prime tornadic hodographs. However, the reason why they are like that is due to the surface inversion. If the surface inversion was mixed out then the 0-1 length would be shorter, but still capable of causing trouble.

LWX is confident too much sfc stability, but I’m not so sure we don’t get some sort of dynamics that could break through. Won’t be widespread.

I have a sneaking suspicion looking at satellite that places in N Baltimore and higher elevations of Harford co are plummeting right now.

Snowing at about 6kft above DC/Baltimore:

Out at Bacon Ridge, love that area. And yes, the snow line can be very pronounced. I've seen Trace to 2" within 30 feet vertical.
