A few showers will linger overnight, with some morning fog and drizzle on Thursday. Amounts will be light, with somewhat heavier amounts, as during the day Wednesday, near the North Carolina line and west of Interstate 77. We’ve seen a cool wedge of air with much drier air aloft hang in, and the trajectory of the storm and its moisture feed hasn’t been sufficient to overwhelm that dry air with thick Gulf of Mexico moisture. So, as expected, this has been more of a dribble than a real rain for the New River and Roanoke valleys northeastward.
We’re basically going to resume the slide into fall after this system goes by, with highs in the mid 60s to mid 70s and lows in the 40s and lower half of the 50s likely most days over the next week, maybe two. A cold front arriving Monday (weather map for Monday morning at left) will reinforce the seasonable temperatures and dryness, possibly squeezing out a few showers or — maybe — an isolated storm ahead of it. There was some online weather geek excitement about the possibility of a nor’easter-type low forming near Cape Hatteras and moving north along the East Coast toward New England, but newer guidance is coming into line suggesting this storm system will be farther offshore (also shown in the inset weather map). It may ultimately become a powerhouse low up near Newfoundland, which could help pull down some pretty chilly air next week. This low does NOT appear likely to be any kind of substantial weather maker for Southwest Virginia or even, at this point, the coastal regions nearest us.
