The National Weather Service says Nashville area residents should brace themselves for a blast of Arctic air that may bring 2 to 4 inches of snow and the coldest temperatures so far this season to Middle Tennessee.
A “potent winter storm system” is expected to move into the area late Wednesday night through Thursday, according to the NWS.
An upper level disturbance will drop rapidly out of Canada on Wednesday and into the northern Plains and move southeast into the Middle Mississippi valley Wednesday night and across the Ohio and Tennessee valleys during the day Thursday, the NWS said.
The main impact will bring 2 to 4 inches of snow accumulation between 4 a.m. and 6 p.m. Thursday.
A winter storm watch has been issued which means there is a potential for significant snow, sleet or ice accumulation.
The NWS says the snowfall will stick to road surfaces with no melting.
Winter will continue its grip on the Midstate with another surge of Arctic air that will move into the area in the wake of the system and will drive temperatures into the single digits Friday night with wind chill readings below zero.
