TodayGrinch Storm – High 66°

A warm front has moved through Middle Tennessee late this morning, which is giving us a chance for hit/miss showers until tonight’s Grinch Storm (disturbance moving out of the Southern Plains) makes it to Nashville late this afternoon / early evening… Just in time for the Nashville Christmas Parade.

The GFS and Euro models generally agree.

Here’s a regional current radar loop:

Bottom Line

It’s going to rain this afternoon/tonight until tomorrow morning. We may even see a few innocent, no-worry thunderstorms. You will need rain gear, but note: the temp will be in mid-to-low 60°s the whole time. So, not a cold rain.

Saturday – Cold Front; End of Rain – Wake Up & High 57°

A cold front will push through Middle Tennessee early Saturday morning behind the Grinch Storm.The NAM shows the line of showers accompanying the cold front to our SE by 8 AM.

This will usher in a cooler and drier air throughout the day. Our high temperature will be reached during the morning and then temps will drop throughout the day.

From 12 PM to 6 PM temps will drop from the lower 50’s to the lower 40’s.

Sunday – Cool & Mostly Sunny – Wake Up 37°, High 52°

As cooler and drier air continues to filter in, we will become mostly sunny during the afternoon.
