Either way, you have to have a layer of cold deep enough for that to happen. So, I would think that for places like here in Winchester, once the layers above start going below freezing, we are going to flip to snow. Link to comment Share on other sites More sharing options...

What we have out here, evidently, is warm, then cold, then warm. Pretty much everything is above freezing but there must be a pretty good slice up there somewhere that is below freezing.

Eskimo Joe Posted January 23, 2017 Share Posted January 23, 2017 Quote 000 FXUS61 KLWX 231901 AFDLWX Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 201 PM EST Mon Jan 23 2017 .SYNOPSIS... Low pressure over southern Virginia will track northeast off the Delmarva tonight. A cold front will pass through the area Wednesday night. An upper-level trough will build overhead for the end of the week into the weekend. && .NEAR TERM /THROUGH TONIGHT/... This has been an extremely challenging forecast given the variety of problems presented by the low...and its interaction with the high pressure over northern Maine. The pressure gradient has caused strong easterly winds which led to the wind advisory over the eastern part of the forecast area...and this easterly fetch led to a strong moisture flow off the Atlantic and areas of moderate/heavy rainfall. Temperatures have turned cold enough at higher elevations to cause the rain to change to snow in the Highlands...and freezing rain in Shenandoah National Park. These same wids are responsible for waters of the Potomac and Ches Bay to rise...and we've even seen a few lightning strikes. In good news the low is tracking to the northeast - slowly, but it is happening. The heaviest precipitation should be coming to an end this evening. Wind advisory and winter weather advisories are in effect until 7 pm. Flood watch for the I-81 corridor until 11 pm. Link to comment Share on other sites More sharing options...

Eskimo Joe Posted January 23, 2017 Share Posted January 23, 2017 Based off the latest SPC mesoanalysis...925mb temps are at or below freezing north of I-70. Wouldn't be surprised if you start seeing more sleet reports there over the next hour as we lose the sun. Link to comment Share on other sites More sharing options...

This winter has been so awful that I'm grasping at straws. Not ruling it out, but even though the NAM precip type is showing snow and sleet overnight, the NAM microphysics output is less enthused. It certainly suggests sleet and maybe snow mixing in, but accumulations would likely be limited to far northern MD. Of course, things seem to be running colder this afternoon than progged, so.....
