Temperatures are expected to continue to rise into the lower 70s in some areas by Wednesday afternoon with the high temperature forecast for 71 degrees, according to National Weather Service forecasters.
A strong arctic cold front is expected to push across Middle Tennessee on Thursday, which will likely interact with a moist southwest flow of air in the upper atmosphere and produce an extended period of rainfall, some of which may be heavy locally. Rainfall totals Thursday through Friday night are expected to be between 2-3 inches over most of Middle Tennessee.
As arctic air pushes deeper into Middle Tennessee late this week, a wintry mix could develop. Temperatures are expected to tumble after the cold front passes, and by Friday afternoon, will reach the lower and middle 30s over about the northwest half of Middle Tennessee.
Rain is expected to change to a mix of snow and sleet Friday afternoon in areas north and west of Nashville, including Wilson County, and change over to snow and sleet early Friday night.
Forecasters said it is increasingly likely an accumulating snow will take place Friday night and into early Saturday morning. Another episode of wintry weather is forecast for Saturday night and early Sunday with freezing rain expected.
