Thunderstorm cloud tops rising nearly 10 miles above ground level fueled convection and heavy rains Monday evening. A USGS rain gage located near the Lake Murray Dam measured 3.91 inches of rain between 8:00 and 9:00 PM. Afternoon high temperatures in the upper 90's were observed Wednesday through Friday. At 1:00 PM Thursday, McEntire AP near Eastover was reporting 95 degrees while Myrtle Beach with a 15 mph southeasterly seabreeze noted 86 degrees. Localized thunderstorms during the hours of peak heating produced golf-ball sized hail on Mt. Pleasant Wednesday and in both Hampton and Calhoun counties on Friday. Friday's high winds downed trees along Interstate 26 in Laurens, temporarily closing both lanes. Large oaks and pines were toppled in western sections of the city of Florence. Saturday's severe weather included gusting winds that damaged watercraft along Bonneau Beach on Lake Moultrie. A weak boundary neared the state on Saturday with increased clouds, some moderation in the heat and passing thundershowers.
