A photo from a walk I took this morning, as Masons Knob in southern Roanoke County pokes above low clouds and fog. Gradually, the cold-air wedge will break today — locations that get more sun may shoot into the 50s, while others hang stubbornly in the 40s (or even 30s, where there is ice and thick clouds remain, mainly higher slopes of the Blue Ridge). Sunday looks to be a nice day, with sunshine and many highs in the 50s. A new storm system approaches late Monday into Tuesday, and there may be just enough cold air wedging down the east slopes of the Appalachians again for some patchy snow, sleet or freezing rain at the start. It appears the southerly flow around this low will be strong enough to sweep warm, moist air in for mostly rain — and perhaps a substantial amount of it, near an inch or so. Behind this low, cold northwest winds will resume for mid to late week, and a blocking pattern of high pressure in northern Canada and a trapped upper low in southeast Canada will keep unseasonably cold air circulating into our region for several days. It’s unclear if there will be widespread snow chances during this time, but almost certainly northwest winds will lead to a period when upslope snow squalls may occur intermittently for several days in the regions that see them most (West Virginia’s mountains, ridgetops near the Virginia-West Virginia line, areas west of I-77, and sometimes bleeding eastward into the New River Valley.) A cold and windy start to March appears very likely.
