ATTN...WFO...HUN...OHX...MEG...LMK...

12:30 p.m.– Not a whole lot has changed. Waiting on the “cape” to lift over Middle Tennessee to allow all this instability to interact ahead of the front. Still expecting some pop-up cells this afternoon and then a solid line around drive-time. Straight-line winds and hail seem to still be of immediate concern. Later flooding and strong, gusty winds will cause havoc through the overnight. Still think we will see a Wind Advisory and based upon the watching this since this morning a Tornado Watch to be issued at some point this afternoon for our area. We will update should that happen

A very slow-moving front will bring a chance of strong to severe weather to Middle Tennessee today.

  • High winds will come ahead of the front, expect a Wind Advisory to be issued later this morning.
  • Temperatures will reach the mid-80s and may break records.
  • With the high temps, expect multiple rounds of strong storms ahead of the main front later this afternoon
  • Part of our viewing area ( Nashville, Franklin, Columbia and points West) are under a level 3 of 5 for severe weather. Level 2 for those East.
  • Winds, hail and flooding seem to be the main concern. A tornado or 2 is not out of the question.
  • Looking to the west this morning pretty much the whole state of Arkansas is under a tornado watch.
  • TIMING: Here is where it gets a little harder to project. Basically, looking at 4:00 p.m. into mid-evening for the real severe storms, however, this front is a real slow mover, and more storms could pop up in clusters afterward.
  • WEDNESDAY NIGHT into THURSDAY: The gusty winds will stick around and we will become more concerned with heavy rains and flooding possibilities overnight.

This is a forecast that will be tweaked throughout the day and we will post as things change.
