Mesoscale Discussion 1270
NWS Storm Prediction Center Norman OK
1238 PM CDT Fri Jun 13 2025
Areas affected...Central Tennessee and Kentucky...northeastern
Mississippi...and northwestern Alabama
Concerning...Severe potential...Watch unlikely
Valid 131738Z - 131945Z
Probability of Watch Issuance...20 percent
SUMMARY...Thunderstorm coverage will continue to increase across the
TN Valley through this afternoon. Damaging wind gusts will be
possible.
DISCUSSION...A few clusters of thunderstorms, and new rapid
development via visible satellite imagery, are being observed from
far northeastern MS into middle TN and central KY. This convection
is blooming in a low to moderately unstable air mass, with surface
dewpoints/temperatures in the mid 70s to low 80s under a relatively
cooler pocket of air aloft, east of a mid-level cyclone centered
near the MO/AR border. Based on the latest VAD profiles around the
region, mid-level southwesterly flow continues to slowly increase.
Some organization into line segments will be possible through this
afternoon given ~35 kt of effective deep layer shear, with
precipitation loading aiding in a threat of locally damaging wind
gusts. However, a lack of persistent, stronger mid-level flow later
today should limit the overall severe weather threat and a weather
watch is not anticipated at this time.
