Forecast Discussion

An Extreme Heat Warning is still in effect until 8 pm EDT tonight. Please continue to heed caution with the high temperatures and relative humidity. Additionally, NWS Charleston has issued a Heat Advisory from 8 am EDT to 8 pm EDT Friday. While the issued advisory may not seem as severe as the warning, we ask you to please continue to stay hydrated and cool in this heat. Friday’s heat index could reach as high as 104. Thankfully, temperatures will slightly trend downward by the weekend as the persistent high-pressure that has sat over the eastern United States slowly dissipates. While that doesn’t mean we’ll find ourselves back with significantly cooler temperatures sadly, we will begin to see a slight relief to the harsh summer heat as temperatures return to slightly above and near normal by this time next week according to the Climate Prediction Center.

While overall showers and possibly some thunderstorms are possible all around the next few days, the biggest chances for storms will be Saturday and Monday evenings. Currently, these storms are not expected to be severe but may produce locally heavy downpours and gusty winds for brief periods of time.
