Tornado Watch Until 10 AM

A Tornado Watch is in effect until 10AM for much of central Virginia, where conditions are favorable for severe thunderstorms this morning. Ample moisture has been surging northward into the Mid-Atlantic for a couple days, making our atmosphere unseasonably warm and humid. While a large, intense low pressure system spins over the Great Lakes region, ample lift will be provided for storm development today and tonight in our region. The cold front associated with this low pressure system will begin moving into the Commonwealth today, triggering more storms. It looks like we'll have several rounds of thunderstorms, first this morning, another late afternoon, and a final round overnight into early Thursday morning. Threats include isolated tornadoes, damaging wind gusts to 70 mph, and large hail. Torrential downpours and frequent lightning can accompany these storms as well.
