Dangerous Heat & Humidity

Posted: Updated:

Good morning - and happy Friday Eve!  The big weather story today is going to be high heat and high humidity.  Temperatures will approach records this afternoon - in fact, we'll be within a degree or two of our records in both the Upstate and Mountains. 

The GSP record is 99 degrees, and I'm calling for a high of 98 degrees at the airport this afternoon.  Asheville's record is 94 degrees, while my forecast high there is 92°.  Even if we don't make the record books, it will FEEL like we did - because high humidity will make it feel even hotter.

Dewpoints will be in the upper 60s, even near 70 degrees - and that puts us in "oppressive" territory.  Be prepared for heat index values in the mid (perhaps even upper) 90s in WNC, while Upstate "feels like" temperatures will range from 100 to 105° in most spots.

Southern and eastern counties are under a Heat Advisory from noon until 7 PM.  In these areas, heat index values will range from 105 to 107 degrees (air temperatures may hit triple-digits during the afternoon in these southern and eastern areas).  The following counties in our viewing area are included within the advisory: Elbert, Abbeville, Greenwood, Union and Laurens.

Most of us will stay dry today under partly cloudy skies, but we can't rule out a pop-up shower or storm during the afternoon.  With that said, any storm activity will be isolated at best.  Tomorrow will bring a higher storm chance as a cold front approaches.  The main storm chance will be in the Mountains - I don't expect too much storminess in the Upstate.

Tomorrow will remain very hot and humid - in fact, temperatures and dewpoints will be nearly the same as today's numbers.  Another round of Heat Advisories are possible during Friday afternoon.  The weekend will bring lower temps and dewpoints - but it will still be very warm and muggy on Saturday and Sunday.
