We are headed into the shadow of the Appalachians for our forecast on this fine September day. Well, let’s see the forecast before we decide whether or not today is all that fine for Blacksburg.
At 1155AM, ET, Blacksburg was reporting a temperature of 60 degrees with overcast skies. On the western slope of the Appalachians, there was a southwesterly flow out of the Gulf, flush with moisture and warm air, leading to the potential for cloudier skies in areas where there was turbidity in the atmosphere. There has been a standing surface trough extending from western Virginia to southeastern Missouri, and its interaction with the moisture rich flow is triggering some showers over southern West Virginia, but will lead to clouds over Blacksburg.
A strong, autumnal wave is moving through the Upper Midwest and will begin to pull the surface trough northeast and shear it apart. While this will lead to some temporary clearing in Blacksburg, it will also introduce a more southeasterly flow off the Bight of Georgia will keep some dammed up moisture over the region, and clouds accompanied by some isolated spots of drizzle will continue to be possible.
