In case you missed it, linked here is an amazing time-lapse video of the snow collecting on Virginia Tech’s Drillfield, shot from Burruss Hall. And someone going by the name “Hokie_94″ posted a time-lapse video from Salem on youtube, in which the trees can be seen sagging with the weight of snow.
This weekend can’t match last weekend’s 70s, but after Thursday’s snow and a chilly Friday, it will be fairly mild following Saturday morning’s radiational cooling and snowpack-induced chill in the teens and low 20s (watch out for black ice) . Highs may be able to reach the low 50s in Roanoke and areas to the south and east, especially those with little snowpack, on Saturday. Elsewhere, 40s are likely, with sunshine. Sunday may be similar in temperatures, though an Arctic front will be nearing the region. Melting of the snowpack will continue, though shaded areas and higher elevations and places that got especially deep snow likely keep at least some snowpack until the Arctic blast hits Monday-Wednesday. As it stands now, it appears that blocking high pressure over Greenland will not force the most extreme cold this far south, and that the core of the polar vortex will swing eastward from a prime position to deliver extreme cold, plus the core of the cold will move east quickly. Still, lows in the single digits to mid teens appear likely by Wednesday morning across the region. A moderating trend will begin late in the week. Unlike the wet week we just had, precipitation looks to be scant over the next 5-7 days. Upslope northwest winds over the mountains and, perhaps, a few disturbances caught in the northwest flow may bring some chance of snow showers in the Sunday-Tuesday timeframe. By late week, a stronger low is expected to develop in the central U.S. and track east or northeast, bringing a chance of precipitation next weekend. I think this merits some attention for winter weather potential because, while most forecasts currently point to a storm track to our northwest and enough warming that would more lean to some rain, it is very possible that, after such an Arctic shot, cold air will stubbornly linger banked east of the mountains.
