The National Weather Service's Storm Prediction Center has issued a Severe Thunderstorm Watch in effect until 9 p.m. for the entire metro region (that's in addition to the Flash Flood Watch issued for 5 p.m. through late tonight). Here are excerpts from the watch text:
HAIL TO 2 INCHES IN DIAMETER...THUNDERSTORM WIND GUSTS TO 70 MPH...AND DANGEROUS LIGHTNING ARE POSSIBLE IN THESE AREAS.
REMEMBER...A SEVERE THUNDERSTORM WATCH MEANS CONDITIONS ARE FAVORABLE FOR SEVERE THUNDERSTORMS IN AND CLOSE TO THE WATCH AREA. PERSONS IN THESE AREAS SHOULD BE ON THE LOOKOUT FOR THREATENING WEATHER CONDITIONS AND LISTEN FOR LATER STATEMENTS AND POSSIBLE WARNINGS. SEVERE THUNDERSTORMS CAN AND OCCASIONALLY DO PRODUCE TORNADOES.
We think the best chance for showers and storms, severe or otherwise, in the metro area starts around 5 p.m. and continues on through the evening. See our latest full forecast here, and check back for PM Update between 3 and 3:30 this afternoon.
