MYRTLE BEACH, SC (WMBF) A Severe Thunderstorm Watch has been issued for the Grand Strand and Pee Dee areas until 10 p.m. Sunday night.
A watch means conditions are favorable for severe weather to develop. The heat and humidity have helped the atmosphere become very unstable this afternoon.
The main threats from any thunderstorms that do develop could produce large hail and damaging winds.
The Excessive Heat Warning has been canceled for Sunday night. The heat index values have ranged anywhere from 105 to 115° this afternoon.
Monday it will be hot again, we may see the heat warning extended one more day. Then Tuesday through the rest of the week, temps will start to lower little by little which will take us back to normal for this time of the year.
