NASHVILLE, Tenn. (WKRN) – We will need to be on the lookout for severe weather in the form of damaging winds, hail, and possibly tornadoes over the next two days.
The timing for Monday appears to likely be the late afternoon and evening, and although severe weather is possible in all of Middle Tennessee, the threat will be higher from Nashville and I-65 eastward.
On Monday, The Storm Prediction Center puts northern and eastern Middle TN in the “Enhanced Risk” category (a new one between Slight and Moderate), with a 30% chance for 58 mph or higher winds in that area. The rest of Middle TN is in the Slight Risk category (deceiving term, it still means strong storms are possible).
Tuesday, that Enhanced Risk is from Nashville eastward with the Slight Risk elsewhere. The timing on Tuesday could be both early morning and evening.
We certainly have the heat and humidity for storms to work with, but the wind dynamics will be unusually strong for July.
Strong “bow echoes” (lines of storms on radar that are shaped like an archer’s bow due to strong winds bending the line) are possible with 58-75 mph winds in them.
It is possible that a “Derecho” (a large bow echo that can sweep across several states) could drop southeast out of the Ohio Valley/Great Lakes region into parts of the mid-south. Derechos can cause damaging winds, localized flooding, and occasionally tornadoes.
