WEEKLY SOUTH CAROLINA WEATHER 2017

November 6, 2017 - November 12, 2017

WEATHER SUMMARY:

Patchy dense fog began the week's weather on Monday morning. Zero visibility was reported at airports in Laurens, Colleton, and Marlboro counties. CoCoRaHS observers in Union, Sumter, and Horry counties also reported very foggy conditions. After the fog cleared, high pressure and a southwesterly surface wind helped push afternoon temperatures into the mid-80s on Monday. The high temperature at the Charleston Air Force Base reached 82 degrees on Monday. A weak cold front sagged slowly southwards over the state Tuesday evening bringing cooler temperatures and scattered showers. The COOP observer at the Cleveland 3S site reported a rainfall amount of 0.73 inches falling during a 24-hour period ending Wednesday morning. Wednesday's high temperature reached 74 degrees at the Beaufort Marine Corp Air Station.

An area of low pressure developed over the Upstate on Thursday and interacted with an offshore cold front. This offshore front provided abundant moisture for a day-long Thursday rain event. The Greenwood County Airport's high temperature only reached 51 degrees on Thursday. Thursday's rain totaled to 1.35 inches at the Orangeburg 2 COOP site. Clear skies on Friday allowed the temperature to rise to 70 degrees at the Orangeburg 2 COOP site. Friday and Saturday were dry.

A cold front ahead of a large, cold, dry Canadian air mass passed over the state Friday night. Temperatures dropped rapidly behind the front. The state's lowest Saturday morning was 27.5 degrees on Sassafras Mountain. Cool high pressure settled over the state for the weekend. Caesars Head reported morning low temperatures of 28 and 29 degrees on Saturday and Sunday respectively. A weak upper level disturbance brought scattered showers to the Upstate Sunday afternoon. The Rock Hill-York County Airport received 0.35 inches of rain on Sunday.
