Severe Storms rocked the region this afternoon, wind damage common...

Good Monday evening…sections of the coverage area are picking up and cleaning up from a severe weather event that occurred during the late afternoon hours. A backdoor front, jet stream energy and sufficient surface instability helped trigger a line of severe thunderstorms that began across the Tennessee Valley during the late morning hours and intensified across the Western Carolinas as we reached peak heating.

 

Today’s severe weather included a total of four Severe Thunderstorm Warnings issued by the National Weather Service. Multiple reports of wind damage was submitted area-wide with the heaviest concentration across the Foothills from Northern Rutherford County northeast to sections of Alexander County.

 

Storms were crossing into the mountains around 3 pm today and encountered high surface instability east of the Blue Ridge. As you can see on the meso-analysis, CAPE (Convective Available Potential Energy) values ranged from 2500-3000 which is more than twice the amount of CAPE needed for thunderstorm development and persistence…

The storms really began to intensify once it tapped into the surface instability and by shortly after 4 pm the first severe weather warnings of the afternoon were issued in the foothills. These storms translated southeast through the evening commute impacting most everyone in the coverage area with some combination of heavy rainfall, damaging winds, hail and deadly lightning. The severe weather threat started to diminish from west to east a couple hours after the initial reports came in and by sunset all that was left was mainly stratiform rainfall east of the mountains.

The severe weather threat has ended for tonight, thankfully…additional storm chances are in the forecast including tomorrow with temperatures remaining near or above late June values…
