WEEKLY SOUTH CAROLINA WEATHER 2018
April 9, 2018 - April 15, 2018
Low pressure west of the state produced overcast conditions and light rain during the morning of April 9. North Myrtle Beach reported receiving 0.47 inches of rain while Charleston reported only 0.16 inches. The morning low temperature was 32 degrees at Jocassee and the stubborn overcast prevented Orangeburg from warming above 62 degrees. High pressure built in from the west on April 10. Cedar Creek began the day with a low temperature of 38 degrees and the USC COOP observer in Columbia reported an afternoon high temperature of 70 degrees.
High pressure dominated the remaining week's weather until Sunday, April 15. On Wednesday, April 11, Columbia and Greer began the day with a low temperature of 46 degrees.

Santuck reached an afternoon high of 77 degrees. Warming continued on April 13 with USC reaching 84 degrees. Sandy Springs began the weekend with a morning low temperature of 42 degrees on April 14. Sunny skies and a warm, brisk southwest wind helped Columbia and Florence warm to 85 degrees.
On April 15, a sprawling, deepening low pressure system threatened the state with a strong cold front and a squally, pre-frontal trough. Before the frontal passage, Clemson and Greenwood reported a morning low temperature of 47 degrees. The Charleston Airport reached 82 degrees. The pre-frontal trough produced numerous strong thunderstorms, periods of blinding torrential rain and strong wind gusts as it thundered across the state. Columbia Metro Airport observed a 74 mph wind gust at 2:24 PM. Sustained winds reached 33 mph. The Charleston Airport reported 36 mph winds gusting to 50 mph later that afternoon during a strong thunderstorm. Strong thunderstorm cells in the trough produced five tornadoes (table below). The five tornadoes and straight-line wind gusts uprooted numerous trees, damaged structures and vehicles, and knocked out power to 50,000 SCE&G customers. Florence reported a rainfall total of 2.48 inches. The National Weather Service in Greer reported a rainfall total of 2.31 inches
