Severe Storms Possible Monday Afternoon

The upper-level storm system spinning into the Ohio Valley region Monday will provide a chance for strong to severe thunderstorms in much of the Commonwealth Monday afternoon and early evening. The green area in the map below indicates the region likely to have strong storms. Risks will include large hail and damaging winds, but there is also a threat for isolated tornadoes, particularly in the Eastern half of Virginia.

The severe risk will be enhanced this afternoon with any breaks in the clouds we get to allow extra daytime heating, whereas the risk will remain more marginal with overcast skies. However, several other factors will aid storm development, including a deepening upper-storm system, lower-level wind shear, ample lift and surface convergence, and instability developing in the afternoon.

We'll be watching this situation very closely today!

It was one year ago, today that we had a brief tornado in eastern Hanover county. I hope today is not a repeat.
