Rounds of severe storms possible in Middle TN, Southern KY through early Friday

NASHVILLE, Tenn. (WKRN) — Through Friday morning, there will be a daily chance of strong to severe storms. The unseasonably warm air in our area (temperatures in the 80s) will aid our storm risk in the coming days.

This morning, a line of rain showers and isolated storms are moving across the region. Through 9 AM, these storms will remain below severe limits.

In the 8 AM update, the Storm Prediction Center continues the Marginal Risk (level 1/5) for areas near and east of I-65. The morning storms will clear the Cumberland Plateau by midday. The focus of today’s severe risk is the possibility of isolated storm development this afternoon in the peak heating of the day.

Future Tracker barely develops any storms in the afternoon hours. At this time, the storm chance appears unlikely this afternoon. If a storm occurs, hail & wind would be the primary risk.

Thursday is the day to watch. A widespread risk of severe weather is possible. All of our area is in the Marginal Risk (level 1 out of 5), but far northwest locations (including Henry & Stewart counties in Tennessee, and Christian, Muhlenberg, and Trigg counties in Kentucky) are under the Slight Risk (level 2 out of 5). The threats here are focused on hail & wind gusts.

Temperatures will be VERY WARM on Thursday, reaching the middle to upper 80s (possibly near 90°). Nashville could break the record of 89° set back in 1955. This will be ample fuel for storm development, and storms will become likely as a cold front approaches Thursday afternoon & night.

For Thursday, storms could develop in the heating of the afternoon. Then, as the cold front approaches, storms increase again late Thursday into Friday morning.

When looking at the ingredients for severe weather, the storms that could impact our area on Wednesday lack a trigger (cold front, upper-air support), but have the available moisture, instability, and wind shear.

However, on Thursday the trigger will be an approaching cold front. That combined with very unstable air, Gulf moisture, and decent wind shear will all lead to multiple storms with some turning strong to severe.

Over the next few days, the overall severe threat will be strong gusty winds. Pockets of heavy rain will be likely through Friday morning. The hail and tornado threats are low but not zero.

Temperatures cool down for the weekend with additional rain possible on Sunday. Next week, highs in the 60s to near 70, but chilly mornings in the 40s.
