UPDATE 5:30 PM: A new line of storms moving out of West Virginia will likely cross part or all of Southwest Virginia this evening. With temperatures having recovered into the 80s with some sunshine, there may be enough instability for a few strong to severe storms, with locally severe wind gusts as the major threat. Brief torrential rain is also possible. Keep an eye on the radar. END UPDATE
Forecast models seemed to have had a pretty good handle on this morning’s cluster of rain and thunderstorms, sliding southeast out of West Virginia. Southwest Virginia will be be on the western side of the area of rain and storms, with heavier rainfall amounts likely north and east of Roanoke. The morning arrival of the storm cluster will likely lead to clouds and atmospheric stabilization that will deter the renewed development of potentially strong and locally severe storms later today, but any return of sunshine later in the day will offset that at least somewhat. Chances of severe weather — mainly some localized damaging winds — will be greater east and south of Roanoke (and perhaps west of I-77, too), but this does not appear to be a large-scale threat, and as of this writing, had not led to even a slight risk zone being issued by the Storm Prediction Center, though this may change later in the day especially south and east of Roanoke.
Heading into Labor Day weekend, we’ll have warm, sticky days with some chances of showers and storms. A significant cold front is expected to push through early next week that could bring substantially cooler, drier weather to start September.
