Flakes are HUGE here...the mixing is near. 

 

Smaller flakes but no audible sleet yet (just stuck my head outside) here in Centerville even though correlation coefficient indicates changeover any second now. Temp continues to drop slowly from today's high of 28 @ 1130. Down to 25.7.

I hope not Maryland OBS are still reporting snow and the radar looks good as the mix line at least right now isn't making it north over the PA line. Going South and east. 

First pings of the day have commenced in the historic district. I'd say 80/20 in favor of snow. (snow has gotten clumpy)

Storm developing as expected w/ heavy snow now falling in Hagerstown, MD...so that will arrive here ~4pm or so. However, a deep near-freezing layer (3k'-7k') will arrive over southern PA this evening--so I remain convinced of an extended period of sleet, esp south of Route 30.

 

Just wanted to point out that looking at current KDOX radar, the CC < 1 appears to be from 3k' to 7k'

 

This is why I follow Horst, and why his retirement is so "painful" to LSV weather enthusiasts (no offense meant to Mag, Allweather, or any other mets here, just can't beat decades of local experience)
