Pinpoint Weather: Snow expected Thursday, bitter cold air Friday

Weather Blog

There will be another round of snow this Thursday and the models are all pretty much on the same page. That often is not the case, but it seems that this go-round most are in line with each other. Numerous Advisories and Warnings are in place and can be found by clicking on the weather alert bar at the top of the page. The major difference with this event is that the air is already cold in the region so there won’t be any wasted energy converting the rain to snow during the process.

Here is what we expect but all subject to change as more information arrives:

-The precip will begin as all snow except for a sliver of our SE counties (Halifax, Charlotte and Pittsylvania) where it will begin as rain and quickly become snow.

-The timing of the snow is from 2pm in the Western Mountains, 4pm along 81 and 4:30 in Lynchburg.  Piedmont counties see some snow by 5 pm. The back edge will clear Roanoke just after midnight as it tapers off (or exits) from west to east.

-Amounts are in the 2 – 3” range in the Roanoke region, more like 3” in Lexington and Wytheville. Because Lynchburg has a good deal of snow still on the ground, they may get more like 3 or 4”.  The mountains will get the lion’s share of the snow, so our cameras in Burkes Garden and Lewisburg, Snowshoe, and Lexington will be a nice resource.  Amounts in the mountains may be in line with a 4 – 6” range.

-The real danger, other than the travel, will be the bitter cold air slated to follow on the heels of the snow.  Temps on Friday morning will be in the teens and some single digits and the WNW winds around 20 mph will make it feel sub-zero in some mountain locations in the NRV and Highlands, the single digits along 81.

-Remember to tend to your pets, keep an eye on your neighbors and stay off the roads if you can.  If there is a threat for some icy roads, it will be in Southside along 501 and 58 from Martinsville east.

Friday will be windy and bitter cold to start as mentioned above. I expect to see a decent amount of sunshine both Friday and Saturday and Saturday morning will be even colder than Friday, but with less wind.  Lows or actual temperatures are teens and single digits across the board.

Saturday stays sunny then late day clouds arrive. Warmer air arrives in time for another round of precipitation. Sunday will be much milder as the air ahead of the next round of precip will be in the 40s to 50 so this third round of precip this month should be mostly cold rain, with some snow in the mountains on the back end.
