Strong Wind, Heavy Rain Possible Late Thursday

A strong cold front will bring the threat of severe weather into the Carolinas late Thursday. The Storm Prediction Center has highlighted a level 1 (out of 5) severe threat for our region. Time is on our side as this line will likely lose steam and fall apart as it crosses over the Appalachians and into the WCCB viewing area overnight. However, an isolated severe storm cannot be ruled out. The primary threats will be damaging wind and localized flooding.

Spotty showers will begin Thursday afternoon for the mountains, but the mainline with the heaviest rain will not arrive until late Thursday. The good news is, it will be moving quickly, which will limit rainfall totals for the majority of the area to less than .5″. However, 1-1.5″ of rainfall will still be possible for the mountains which could lead to localized flooding.
