COLUMBIA, S.C. — Election Day across South Carolina started off with some much-needed rain. The Columbia airport had not gotten any measurable rainfall since September 27, but that did change today. More light rain will be possible throughout today. Heavier rainfall is expected late Wednesday and into Thursday.
Monday was mainly cloudy and mild. The Columbia airport reported a high temperature of 77 degrees. On average, we would expect high temperatures closer to 70 degrees this time of the year.
This morning, we did get some measurable rainfall. The Columbia airport got rain for the first time in 38 days. The record longest rainfall drought is 40 days in 1961. The second longest streak is 39 days in 2000.
With abundant moisture streaming in, light showers will continue through this afternoon. Despite the clouds and occasional rain, temperatures are remaining warm, hovering between the mid-70s and 80s, which is above the seasonal average. Expect the rain to ease off tonight, though lingering clouds will keep overnight temperatures in the low to mid-60s.
Tropical Storm Rafael continues to move through the Caribbean. It is expected to reach the Gulf of Mexico by Wednesday. As Rafael moves closer, a surge of moisture will follow, bringing potential for widespread showers and possibly heavy rain from late Wednesday into Thursday.
By Wednesday night, rain chances will rise significantly, with some areas possibly seeing two to three inches of rainfall. Although the last month was dry, there is now a slight risk of localized flooding late Wednesday through Thursday.
The rain moves out late Thursday or early Friday. Dry weather is forecast Friday through Veterans Day. Temperatures will remain above normal.
