Evening severe threat

There are two areas to watch for developing severe weather this afternoon. One is within the severe thunderstorm watch that basically takes in all of Virginia east of the Blue Ridge. The dot I added to this map, from the Storm Prediction Center, depicts the location of Roanoke, just west of the severe thunderstorm watch box (outlined in blue) that includes Bedford, Martinsville and points east. Expect isolated storms and clusters of storms to begin firing in this area the next few areas, with damaging winds the greatest severe weather risk. Shear, or the shifting of winds with height, is only moderately strong today, so severe weather should be scattered in nature and probably not widespread or especially violent.

The second area to watch is the line of storms visible in West Virginia. This line, marking the boundary of a strong cold front cutting into the hot air mass that has dominated weather across the U.S. the past week, will race eastward through the rest of the evening. Expect a fairly brief period of gusty winds and heavy rain as this line zips through later this evening.
