MYRTLE BEACH, SC (WMBF) - The first heat wave of the year will send temperatures soaring to record levels at times through the weekend.


Record high temperatures are likely on Thursday as the first heat wave of the season brings temperatures into the 90s. Morning temperatures in the 60s to near 70 will quickly climb into the upper 90s to near 100 inland and to near 90 along the Grand Strand. The forecast high temperature of 90 in Myrtle Beach will be the first 90 of the year and hot enough to tie the old record of 90 set in 2001. In Florence, the previous record of 98 set way back in 1962 is in jeopardy with a forecast high temperature of 99.

Storm chances are very small on Thursday with such high heat and humidity, a few storms may develop by the afternoon. We’ll have blazing heat that will make the atmosphere very unstable. We’ll also have a lid or cap on the atmosphere. The two work to somewhat cancel each other out meaning IF (big IF) storms develop, they could be quite nasty. The forecast right now is for just a 20% chance of a few storms, but the one or two storms that develop could be strong to severe and LEVEL 2 risk is in place.

One or two isolated severe storms will be possible on Thursday.

For the Grand Strand, Thursday will be the hottest day as an active sea breeze will tend to keep temperatures cooler near the beaches. High temperatures on Friday will be in the upper 80s with temperatures dropping into the lower to middle 80s by the weekend. A few showers and storms will be possible especially on Sunday.

Hot through the weekend.

Inland areas will not benefit from the sea breeze and will continue to see scorching temperatures. Afternoon highs will reach near 100 again on Friday and remain in the lower to middle 90s through the weekend.

Some relief arrives next week as better chances of showers and storms returns.
