Severe weather possible Thursday evening

Severe storm risk exists Thursday evening / night, as of now more so for areas south and east of Mebane - evolving situation

A large dew point drop of around 70F to the upper 50s coincides with strong upper level winds Thursday night, especially for areas south of highway 54, and east of Chapel Hill

A cold front / large dew point drop looks to hang at or about the Virginia / NC border to about 7 p.m; before that strong southerly winds associated with the remnants of tropical cyclone zeta and a low pressure in the vicinity of NW NC will pump up rich moist air from the southern Atlantic / gulf into our area

As the cold front / low / wind convergence zone drops south it’ll push the higher wind field south and east before dew points drop significantly just after midnight

Before the dew point drop, especially in the areas above mentioned a severe storm risk cannot be ruled out, including a risk for an isolated tornado

The dew point drop at or about midnight ends any severe threat (earlier north, later south-southeast)

Much more stable cooler conditions follow Friday into the weekend
