UPDATE: March 25, 2:25pm

NWS Update:

“The earlier showers and storms have obviously moved out of the area and we are left with some partial sunshine and relatively mild air. This is helping to destabilize the atmosphere for additional storms later on. At this time, the short-range models are showing storms moving northeastward into Middle Tennessee from northern Mississippi and Alabama after 3 p.m. and then spreading across the remainder of the mid state during the next several hours. So be on the lookout for an additional Tornado Watch for Middle Tennessee should one be forthcoming.”

UPDATE: March 25, 12:30pm

NWS has updated the timing of the storm (see graphic below).

Again, the main threats are damaging winds, flash flooding and tornadoes.

Original Story

Severe weather, including the potential for tornadoes, golf ball-sized hail, damaging winds in excess of 60mph and flash flooding, is expected in the middle Tennessee area Thursday afternoon and evening.

Currently, a Flash Flood Watch is in effect through 1 am Friday and Wind Advisory is in effect from 4pm Thursday until 4 am Friday

Here’s What You Need to Know

*updates from NWS

  • Non-severe showers and thunderstorms have already moved into southern portions of Middle TN.
  • Most of middle Tennessee is in the “Moderate Risk”
  • Two rounds of severe weather is expected – The first starts this afternoon around 1 pm, west of I-65. These storms could contain strong, long-track tornadoes, large hail and could produce flash flooding.
  • This first round hinges on whether the rains last longer than expected. If they stick around until mid-afternoon (which we don’t expect), this will reduce the likelihood of afternoon severe weather. However, if they end and the sun comes out, this will only act to enhance the severe weather threat between 1 pm and about 6 pm this afternoon. If these storms start to develop, this is when we could see the stronger, long-track tornadoes occur. The best location for this to occur is south of I-40 and west of I-65. Large hail and localized flash flooding is also possible.
  • The second round is expected between 6 pm and 11 pm CDT. This would consist of a broken line of intense thunderstorms that will present the possibility of damaging straight line winds (65+ mph), multiple tornadoes and flash flooding and these threats will be for ALL of Middle TN
