From Thursday morning’s 11:15 AM National Weather Service Forecaster Discussion:

As is common across our County Warning Area…the rain/snow line will set up across
the County Warning Area…but exactly where it sets up and/or how it moves during
the storm is yet to be determined. This will will dictate who gets
how much of what precipitation type. Regardless…quantitative precipitation forecast is forecast to
be Bountiful with this storm. In addition…at least a portion of
our County Warning Area will receive wintry precipitation. Therefore…this storm
has the potential to be a high impact event across the County Warning Area.
The most
likely scenario based on climatology…experience and GFS/ECMWF/sref
blends is for snow (or snow/sleet) at the onset…then for areas
west of the Blue Ridge to remain mostly snow for the duration while
other places experience a messy wintry mix that would include
freezing rain. The best chance of a total changeover to rain would
occur across lower southern Maryland and the Middle Bay. As the storm
re-develops of the middle Atlantic coast…mixed precipitation would
likely transition back to snow toward the end of the event Sunday
morning.

Because of a potential major winter storm headed our way, we’re foregoing weather pictures We’ve been talking about a developing winter storm over the weekend for the past day or so with lots of changing weather in between, so let’s get right into it shall we! First, how about Wednesday, wow, what a nice day, but a really warm one. Here at NCL-Nelson County Life Magazine in Greenfield we reached an afternoon high of 80° at 12:46 PM. Upon the mountain at NCL-Wintergreen Nature Foundation at Devil’s Knob, the afternoon high made it to a mild 62° at 10:43 AM. Other reporting NCL Weathernet stations were in the upper 70’s to near 80 as well. We can say good-bye to those temperatures and by this weekend we will be back in the deep freeze into early next week.

In the graphic above you can see we have the shot at some wintry weather this weekend. Early models show much of the energy concentrating to the NE of Virginia, but as the models continue to run we’ll have to see. It still looks like Central Virginia has the chance for a significant winter weather event. Unfortunately, the valley may actually see an icing event in addition to snow. Upon the mountains you have a better chance of seeing just plain snow. Though a little change in the warm air layer above could make it ice on the mountains as well. It’s way to soon to know right now, you just can’t predict this far out, but a 1-3 inch probability of snow is a good bet. BUT, a slight variation in the track of the storm could mean double or even triple that amount, or none. It’s why you always hear me laugh about these extended predictions, it just changes way too much to be accurate more than 12-24 hours out. As we get closer to the weekend I will more closely examine the snow / ice potential.

The mountains will have a shot at some wintry weather even as early as tonight. Some areas even saw some frozen precip last night, but nothing major. As colder air works in the area a snow / rain mix may occur on the mountains at places like Wintergreen Thursday night, again this won’t be much, but the weekend is a much different picture. Colder air already started filtering in last night, we get very cold by Saturday, Sunday into Monday.

As I said I’ll be watching this much more closely now as we get to within 48 hours of the possible storm event, check here often for updates.
