WEEKLY SOUTH CAROLINA WEATHER 2017
October 2, 2017 - October 8, 2017
A broad ridge of high pressure fixed over the U.S. east coast kept warm and very dry conditions across the state through on Friday. High temperatures reached 92 degrees at the Barnwell COOP stations on Saturday. Coastal CoCoRaHS stations reported meager rainfall amounts during the week. The Bluffton 2.9 ENE CoCoRaHS site reported a 24-hour rainfall total, ending Tuesday morning, of 0.15 inches. A coastal trough developed just offshore on Saturday and produced 0.70 inches of rain at Georgetown.
High pressure weakened and drifted east starting on Friday allowing a moist southerly flow of subtropical air over the state for the weekend. Friday's coastal trough rotated inland early on Saturday bringing a line of light rain and drizzle across the state before noon. The Columbia Metro Airport reported 0.52 inches of rain and a Saturday high temperature of 88 degrees.
Early on Sunday, Hurricane Nate made landfall near Biloxi, Mississippi. With the subtropical high displaced to the east, the remnants of Nate were steered north, then northeast into the Ohio River Valley on Sunday. Although the center of circulation was well west of South Carolina, Nate's expansive cloud shield covered the state. Embedded severe storms crossed over the Upstate and northern Midlands on Sunday afternoon and produced five tornadoes (see table below). The tornadoes produced widespread tree damage along their paths. Numerous homes and outbuildings were also damaged by the tornadoes. Despite persistent cloud cover on Sunday, Summerville observed the state's high temperature of 90 degrees. The Jocassee COOP observer reported a 24-hour rainfall amount of 7.05 inches attributable to the remnants of Hurricane Nate. The Greenville-Spartanburg Airport received 2.42 inches of rainfall Sunday while the Charleston Air Force Base received only one one-hundredth of an inch.
