[html]MD 0917 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR MIDDLE TENNESSEE AND FAR NORTHERN ALABAMA
Mesoscale Discussion 0917
NWS Storm Prediction Center Norman OK
0503 PM CDT Wed May 25 2022
Areas affected...Middle Tennessee and far northern Alabama
Concerning...Severe potential...Watch unlikely
Valid 252203Z - 260000Z
Probability of Watch Issuance...5 percent
SUMMARY...A line of storms may produce strong wind gusts over the
next 1-2 hours, but a general weakening trend is expected this
evening.
DISCUSSION...A bowing line of storms continues to move
north/northeast across northern AL and into Middle Tennessee where a
moist air mass remains in place. MLCAPE is only around 500-750
J/kg, but PWAT is approaching 1.75" which is aiding rejuvenation
along the outflow. Southerly winds at 850 mb around 40 kt may also
be aiding storm speed and outflow.
Objective analysis indicates that storms will eventually near the
eastern gradient of instability, with MLCAPE at or below 250 J/kg
over eastern Middle Tennessee. As such, while an isolated severe
gust may occur in the short term, the threat should diminish 23-00Z.
