After a very mild and pleasant Monday, winter will make a preliminary appearance on Tuesday as a strong cold front crosses the region and ushers in a shot of Arctic air. Rain overspreads the region overnight and then changes to a wintry mix then snow from the top down and from west to east across the mountains Tuesday morning. We expect just a dusting to around an inch for the vast majority, although areas along the TN border and higher elevations above 4,000 feet could receive one to three inches. A few lucky spots in the high Smokies might get a bit more than that. Areas east of the mountains could see a few snowflakes before the precipitation ends, but it won’t amount to anything. Rapid temperature falls and gusty northwest winds over 40 mph will generate some single-digit wind chills tomorrow evening in parts of the mountains.
