Severe thunderstorms possible again today
Posted Jun23, 2008 at 10:06 AM
The
Storm Prediction Center has placed
all of Virginia under a slight risk of severe weather today. By afternoon, as heat builds, it will push moist updrafts into cooler air aloft, which could trigger thunderstorms. The best chance for severe weather, with large hail and high winds, is likely to be be east of the Blue Ridge, where wind conditions through the atmosphere, instability and moisture are more conducive to thunderstorm development. But a cold front hanging to our west could be another trigger for thunderstorms, and cold air will be even lower in the atmosphere there, so storms could have a better chance of producing hail. Daytime heating, the mountainous terrain, and any leftover outflow boundaries from storms during the evening can also help storms develop today. It's a rather complicated situation that could yield some more reports of hail and strong winds, though it appears now that the coverage of storms may be less than Sunday. After today, drier weather will move in for a few days, with temperatures warming back to near normal by late in the week (upper 80s for highs, lower 60s for lows in Roanoke).
