CHARLESTON, SC (WCSC) - Another warm and sticky day starts Tuesday off as high humidity has already created a muggy morning and it will only get worse as the day goes on.
After setting an-all time record high of 102 degrees Monday, temperatures will be back at or maybe even above that mark later Tuesday. Winds are light Monday morning and some smoke from Georgia and Florida wildfires has worked back up the coast during the pre-dawn hours, but it should dissipate as the sun mixes things up by late in the morning.
This afternoon the combination of heat, humidity and the sea-breeze will create another dangerously hot day. Temperatures will reach 99-103 degrees away from the beaches. Combine that with dew points in the mid 70's and that brings the heat index to 105-112 degrees for several hours along the coastal counties.
A heat advisory again is in effect from noon to 8 p.m. due to these high temperatures. Be careful outside today and take plenty of breaks, drink lots of water and if you get too hot call for help. Don't forget to check on the pets to make sure they have water and shade and also check on any older folks that you know may need some help keeping cool.
The heat will begin to break as the sun sets and temps fall back into the lower 80's this evening. Overnight lows fall back into the upper 70's inland and lower 80's near the beaches. Some smoke may again return along the coast by Wednesday morning.
Another hot one is on tap Wednesday, but temps may stay just below 100 degrees.
Tuesday marks the longest day of the year for Summer Solstice. Tuesday has the most daylight hours as summer starts on the calendar at 1:16 p.m. Tuesday afternoon. Starting Wednesday, we begin to lose a little bit of daylight each evening as the days start to get shorter until we reach the Winter Solstice on December 22.
