More Thunderstorms Expected Monday


More thunderstorms are expected in much of Central Virginia from lunchtime through Monday evening. Afternoon dewpoint temperatures are expected to remain in the upper 60's and low 70's, indicating ample low-level moisture, and air temperatures should climb into the mid- to upper-80's this afternoon. The warmth and humidity will combine as fuel for afternoon thunderstorms as the lower atmosphere destabilizes.
Most of the storms should remain below severe limits, but still be strong with wind gusts to 40mph, small hail, frequent lightning, and heavy rain that can lead to flash flooding. A few of these storms may become marginally severe with hail up to the size of pennies or nickels, and damaging wind gusts above 60mph. This threat does warrant a slight risk area for much of Central and Eastern Virginia this afternoon and evening.
