Record setting heat this week

06-13 Weather Feature

A record setting heat wave is developing over the Mid Atlantic, including over South Carolina, where several days of temperatures in the lower 100s and heat indices near 110 degrees are expected this week. A Heat Advisory is already in effect along and east of the I-95 corridor.

06-13 Heat Advisory

Last week, a strong area of high pressure developed over the Desert Southwest and Northwestern Mexico. This atmospheric feature which serves to increase surface temperatures, has slowly migrated eastward and, as of Monday morning, is sliding east of the Mississippi River. As the week continues, forecast models are in agreement that the mid-level high (or “ridge”) should retain a strong influence over temperatures in the Mid Atlantic and Southeast.

Record or near record high temperatures in the upper 90s and lower 100s are forecasted for the next few days from Greenville-Spartanburg in the Upstate to Charleston in the Low Country. Elevated humidity levels across the state should cause apparent or “feels-like” temperatures to hover near 110° through at least Thursday. The Heat Advisory already in effect over the eastern third of South Carolina is expected to be expanded to include most of the state.

With such stifling temperatures in the forecast, it is important to recall heat safety practices. If you must spend time outside, drink plenty of water, take breaks in the shade or inside, and wear loose fitting and lightly colored clothing. Never leave anyone unattended in the car: this includes pets!

The mid level high responsible for the record heat is forecasted to retreat westward over the weekend. This should allow temperatures to sink to the low 90s by Father’s Day.
