UPDATE 12:30 PM: Radar filling in dry slot rapidly and new bands are forming, including one with heavy snow and possibly thunder moving north out of Henry County. Rumors of this snow’s demise are greatly exaggerated! I don’t expect a lot of 6-plus totals but I still think a lot of folks are going to get 2-4 inches and maybe more in some spots with some periods of VERY heavy snow. END UPDATE
UPDATE NOON: Let me clarify since I seemed to have confused some people. Additional snow bands are continuing to develop south of Roanoke and move north and northwest, pivoting around the upper low to the south. Intermittent snow will continue this afternoon, with 2-3 inches possible in the immediate Roanoke area (I have about a half-inch where I’m at just south of the city now). Amounts overall will probably be toward the lower end of forecasts across much of the area — closer to 3 than to 6 or 7 — but the snow isn’t over yet, so we need to monitor trends. Most places that haven’t changed over probably will soon. Some light rain, drizzle or sleet is still possible between the heavier precipitation bands. END UPDATE
The number of comments has been overwhelming, thank you for your support. I’m running well behind just approving comments and probably won’t be able to answer too many individual questions today.
Looking at radar trends — we are still actually on the “warm” side of the upper low, where precipitation is moving from the south. There is a “dry slot” of sorts south of Roanoke — some bands actually redeveloping within it, so not totally dry — and then the colder side of the storm to the west. As the low moves south of us today, some of that western shield should also slowly develop eastward into the New River and Roanoke valleys for additional snow. The bulk of the heaviest snow is likely to occur north and west of Roanoke as the low pivots this afternoon and early evening.
