An upper-level low slipping southeast from the Ohio Valley will likely trigger widespread showers and thunderstorms today, especially from the Roanoke Valley westward. The atmosphere is pretty thick with moisture, so locally heavy rain will be possible, as will gusty winds and some hail in the stronger storms, especially with a pool of cold air aloft that these storms may be able to bubble up into. The best chance of hail or high winds is over far Southwest Virginia no farther east than Wytheville, and not enough to rate a slight risk of severe weather (only a "See Text") by the Storm Prediction Center.
The coastal low is still there, though more offshore and weaker. Nonetheless, it is likely to affect our weather Thursday and Friday, as it meanders a bit back to the west, by pulling cooler air from the northeast into our area. Though the forecast for Thursday now is for highs in the 70s, it might not get out of the 60s if a thick bank of moisture, fog and clouds develops.
Speaking of the coastal low, David Sobotta, who goes back and forth between homes on a mountain overlooking the Roanoke Valley and the Crystal Coast of North Carolina (he has a local blog, View from the Mountain), measured 8.3 inches of rain on Labor Day from the coastal low. Here is a blog post he made about that.
The good news is that the National Hurricane Center no longer considers this low even a slight tropical development risk ... and distant Hurricane Fred is not going to get close to any significant land mass before sputtering out in the high-shear upper winds that are killing Atlantic tropical systems left and right this season.
