Severe Thunderstorms, High Winds in the Forecast; Could Bring Possible Power Outages
Posted at 9:30 a.m.
The National Weather Service (NWS) and county emergency management officials are monitoring the progress of a powerful cold front that is forecast to affect our area this afternoon. With temperatures rising to near 80 degrees there will be an unusual amount of heat energy available for this time of the year to fuel thunderstorms as the cold front passes. The primary threat will be high winds and related power outages. In addition, isolated thunderstorm cells could also bring us hail and wind gusts to 40 mph or greater.
NWS reports scattered severe thunderstorms with damaging winds and large hail are possible this afternoon and evening. The most likely time for severe thunderstorms is between 2 p.m. and 9 p.m.
