Heavy rain is on the way.
Flooding potential remains high in areas in and around the Watch area. Here’s the official text of the Watch:
Rainfall will be heavy. Forecast soundings show all time high precipitable water values for Christmas Day: 1.7″. Think of precipitable water like this. If you stuffed a towel in a giant tube, sent the tube straight up in the air through the atmosphere and let it soak up the moisture, then squeezed it out, you’d get 1.7″ of water.

NWS-Nashville’s Area Forecast Discussion this morning led off with:
The cold front that triggered last night’s severe weather has come and gone. It cleared the clouds and sucked out the humidity (dew point has dropped 14° since last night), but the warm temps remain.
Current Radar
Active weather remains a concern Friday and Monday or Tuesday of next week, although likely not nearly as worrisome as it has been today.
Anyway, I’m exhausted, no energy to update the forecast here on the website.

Severe Weather Risk Increases
The NOAA Storm Prediction Center has upgraded our risk from Enhanced to Moderate – level 4 of 5 on the scale of risks for severe weather. Updates to their outlook include adding wording for long track tornadoes. They are calling this a potential outbreak of severe thunderstorms. Nothing major has changed in terms of thunderstorm timing, but they believe that the threat for severe weather has increased.

Well folks, I’m your special guest blogger (Kelton Halbert) from the University of Oklahoma School of Meteorology. I’m back home in Nashville for the holidays and was asked to lend a hand – so don’t blame David if I butcher this!

There’s nothing on our radar right now, and the HRRR model isn’t too impressed by our overnight rain chances:
We may see a few light showers squeeze out in the middle of the night while the bulk of the rain passes to our SE, clearing out the SE US for tomorrow’s event.
Current Radar
We have plenty of information for you on tomorrow’s thunderstorms, but first…let’s get you through today.
We’ll catch a break from the rain today, as the bulk of it moves east.

HRRR expects rain to continue tonight, gradually tapering off in time for the morning rush-hour:
We expect a few weak thunderstorms embedded in the rain, posing no strong or severe concerns. Some downpours should be heavy, but overall, just a gross night, nothing more.
