Troup County may escape the worst of a storm that is bringing a wintry mix of precipitation to much of the Southeast, but tonight will be the test.
Rain, which began about midnight Monday, has continued, with the total standing at 3 inches at 6 a.m. today in downtown LaGrange. Tonight’s forecast calls for a low of 30 with a mix of rain, snow and sleet until 1 a.m., then a brief period of snow and sleet, followed by just snow after 2 a.m. Snow should end by 9 a.m. Thursday. Any accumulation of snow and sleet should be less than a half-inch.
Other parts of the state could see much worse conditions. The National Weather Service has issued an ice storm warning that is in effect until 1 p.m. Thursday. Troup County is on the southern edge of the affected area, which is on both sides of a line from Franklin to Newnan and Peachtree City to Warrenton.
The southern portion, including LaGrange and Macon, could see a tenth to a quarter of an inch of ice overnight.
However, areas near Interstate 20 face ice accumulations of three-quarters to an inch thick. The Weather Service said that could cause a catastrophe, making travel impossible and causing widespread and extended power outages as ice accumulates on trees and power lines, then brings them down. Power may be out in some areas for several days or up to a week. Warmer temperatures Thursday will melt some of the ice, but it will refreeze overnight, creating patches of black ice on roads Friday.
As the storm moves out, the mercury in Troup County is expected to reach the mid-40s Thursday, then drop to about 32 Thursday night.
There is a slight chance of rain Friday, with a daytime high of 58 and a low of 32. Sunny to mostly sunny skies with highs in the upper 50s and lows in the mid-30s are on tap for the weekend.
