Another Blast Of Wintry Weather Expected Tonight, Wednesday



Low pressure will develop over the Southern Plains and track east toward Tennessee on Wednesday. Moisture will be drawn northward ahead of the low beginning Tuesday night, and with very cold air in place across the mid-state another round of wintry precipitation is expected.

The precipitation is expected to begin as areas of light snow late Tuesday night or early Wednesday. As warmer air moves in aloft any snow will gradually change over to freezing rain during the day Wednesday. A period of sleet is also possible during the transition. The potential for freezing rain will continue into the evening hours Wednesday before warmer air works in changing the precipitation to all rain by late Wednesday night.

The best chance for any significant accumulations of snow and ice will be to the north and east of Nashville where cold air will linger the longest. Regardless, hazardous travel conditions will be possible throughout the midstate beginning late Tuesday night. Stay tuned to your favorite source for weather information for the latest.
