Strong storms in Tennessee Monday evening

This is an archived article and the information in the article may be outdated. Please look at the time stamp on the story to see when it was last updated.

A complex of heavy storms in Middle Tennessee will kick off additional storms farther south this evening, and some of those could impact North Alabama and Southern Middle Tennessee through 10 PM. While most of us won’t get a drop of rain, isolated heavy storms (those in progress and any other that develop) could produce over an inch of rain, gusty winds, and frequent lightning.

There are no plans for a Severe Thunderstorm Watch at this time, but the Storm Prediction Center is monitoring the region (see below).

Storm Prediction Center Mesoscale Discussion on Monday evening

AREAS AFFECTED…PORTIONS OF WRN/MIDDLE TN AND NRN AL

CONCERNING…SEVERE POTENTIAL…WATCH UNLIKELY

VALID 012220Z – 020015Z

PROBABILITY OF WATCH ISSUANCE…5 PERCENT

SUMMARY…A STRONG TO LOCALLY DAMAGING WIND RISK SHOULD CONTINUE FOR
THE NEXT SEVERAL HOURS. WW ISSUANCE IS NOT EXPECTED.

DISCUSSION…OUTFLOW FROM A CLUSTER OF THUNDERSTORMS IN SRN KY HAS
SURGED SWD AND INTERACTED WITH A SECOND BROKEN LINE OF THUNDERSTORMS
OVER PARTS OF WRN/MIDDLE TN OVER THE PAST 30 MINUTES. THE AIRMASS
DOWNSTREAM WILL LIKELY REMAIN HOT/MOIST FOR THE NEXT SEVERAL
HOURS…WITH 22Z RAP MESOANALYSIS INDICATING MLCAPE RANGES FROM
1500-2500 J/KG ALONG AND S OF ONGOING CONVECTION. MID-LEVEL FLOW IS
BEING MODESTLY ENHANCED BY A SMALL PERTURBATION APPROACHING THE MID
SOUTH THAT IS EMBEDDED WITHIN LARGE-SCALE TROUGHING OVER THE ERN
CONUS. LATEST VWP/S FROM KNQA AND KOHX SHOW 20-30 KT OF WLY/NWLY
MID-LEVEL FLOW…WHICH SHOULD ENCOURAGE ONGOING THUNDERSTORMS TO
MOVE SEWD ALONG AN INSTABILITY GRADIENT THROUGH THE EARLY EVENING
HOURS. ISOLATED STRONG TO LOCALLY DAMAGING WINDS WILL BE THE MAIN
THREAT WITH THIS ACTIVITY. THE LACK OF EVEN STRONGER MID-LEVEL FLOW
WILL LIKELY LIMIT THE ORGANIZATION OF THIS DEVELOPING LINE OF
THUNDERSTORMS…AND WW ISSUANCE IS NOT CURRENTLY EXPECTED.
