A light wintry mix falling across Northeast Georgia could continue overnight but isn't expected to result in much accumulation, according to the National Weather Service in Peachtree City.

A developing low-pressure system across the southern Mississippi River Vally is spreading moisture from the Gulf of Mexico into North and Central Georgia, according to a special weather statement from the weather service.

Precipitation is falling as a mix of sleet, snow and rain across Northeast Georgia, with a few reports of light sleet accumulations across Gwinnett and Forsyth counties.

Temperatures will continue to cool through the late evening, but should stay above freezing in most locations.

Minor accumulations of less than half an inch will be possible overnight on grassy areas and other elevated surfaces, mainly north of a line from Gilmer to Gwinnett to Madison counties, according to the weather service.

Drivers are urged to use caution when crossing bridges or overpasses.

Precipitation is expected to taper off Friday morning, switching over to rain.
