Happy Thanksgiving! Weather will just about be perfect on this Thanksgiving, with mostly sunny skies and highs in the 60s. “Black Friday” will be just about the same, until a fast-moving Arctic cold front arrives sometime during the afternoon or early evening. You’ll know when the front arrives because winds will turn the northwest and become gusty. Temperatures won’t plummet immediately with the front’s passage, so it may yet hang in the 60s again, especially Roanoke and eastward. But by Saturday, we’ll have a purely raw, windy, wintry day with highs not making it out of the 30s at many spots west of Roanoke, and barely doing so to the east. As is typically the case with cold northwest-wind flow over the mountains, upslope snow showers may whiten the western slopes over in West Virginia and the parts of Virginia closest to the West Virginia border and west of I-77 — don’t be surprised if a few flakes drift into Lane Stadium for the Hokies-Hoos showdown at midday Saturday (Virginia Tech’s season began with a tropical system threatening rain, and ends with an Arctic front maybe causing flurries). Both Sunday and Monday morning will be in the 20s — deep into the 20s and some teens if the winds can manage to calm down and the skies remain clear one or both of those mornings. But there will be a quick rebound in the temperatures by Tuesday to near the 50s/30s high-low range typical of this time of year, before another Arctic shot arrives mid to late next week. At this time it appears likely that a storm system will form and track too far west along the front next week for a wintry precipitation weather threat in our region, with a new coastal storm, if one forms, likely developing too far north for a significant snow/ice threat in our region, beyond the typical upslope snow squalls. These shots of Arctic air also appear likely to be quick hits, as persistent/redeveloping low-pressure offshore of the Pacific Northwest keeps enough west-southwest wind flow going across the country to move them along quickly. In the short term, it does not appear that a prolonged Arctic air mass will settle in, but the shots of cold will be sufficient in intensity and duration that we will likely average below-normal temperatures both in the 6-10-day and 8-14-day ranges.
