Thanksgiving week in Southwest Virginia will provide little weather excitement — and that is a good thing for anyone traveling or with outdoor plans. We’ll still have the northeast winds in the squeeze play between high pressure to the northeast and the low off the coast of the Carolinas on Monday, so it will likely dawn cloudy and chilly with some patches of drizzle possible. But we’ll see gradually milder weather this week, with highs in the 60s and bright sunshine expected on Thanksgiving Day itself — great weather for the ever-larger Drumstick Dash in downtown Roanoke. A couple of weak disturbances moving through Monday and Tuesday offer only the barest chance of a few sprinkles. Expanding the view nationally (5-day precipitation map linked here), the only really inclement weather through Friday will be the low scraping the eastern Carolinas (heavy rain, gusty winds and some large waves and more beach erosion possible) and repeated heavy rains (and high mountain snows) in the Pacific Northwest, as a slow-moving low spins around off the coast. Some light rain in the central U.S. marks another cold front that will move through our region by Friday or Saturday, possibly entirely dry here. This will turn things breezy and colder for next weekend.
While we may get a shot of breezy cold and perhaps some mountain snow showers by this coming weekend, it’s likely to be a passing shot with a quick recovery. However, there are some growing indications of deep Arctic air banking in central Canada over the next couple of weeks that may, at some point, make a run south. Something to keep an eye on the long-range for a potential early-season cold outbreak, and of course, any wintry precipitation that might develop if storm systems interact with it.
