Today expected to be hottest day of year with excessive heat warning in effect

CHARLESTON, SC (WCSC) -

Wednesday morning is already starting steamy and muggy with temperatures in the upper 70's and low 80's.

An excessive heat warning will go into effect at 11 a.m. and go until 9 p.m. tonight. A mix of sun and clouds will accompany the high humidity making it feel more like 112 to 120 degrees through the hottest part of the afternoon and evening.

Wednesday's heat will be dangerous for everyone, even if you are outside every day and used to dealing with the high temperatures. Heat exhaustion and heat stroke can happen very quickly on days like today and can lead to some serious health problems. Even at the beach and around the pool the heat can take its toll so drink plenty of water, stay in the shade or if possible take breaks inside in the A/C when you can.

A breeze from the South is also bringing smoke up into the Lowcountry from Georgia wildfires.

There will be a few pop up storms later this afternoon as the sea-breeze makes its way inland. With a very unstable atmosphere, some of the storms could be strong to severe with hail and gusty winds.

By this evening, storms should begin to fade away slowly as the sun sets but the heat will be slow to decrease with the heat index not dropping below 100 until after 8 or 9 p.m. Overnight, a few clouds may linger and winds will stay light out of the south. Lows are back in the upper 70's to near 80.

On Thursday, the heat will break just a bit as we are looking for a few more clouds and scattered storms that should help block a bit more of the sunshine but it will again be hot with highs back in the mid 90's and heat index values as high as 110 so look for another heat advisory.

By Friday and the weekend, better rain chances are on the map with highs falling back below normal in the upper 80's thanks to thicker clouds and hopefully some widespread showers.
