AREAS AFFECTED...MIDDLE TENNESSEE INTO NORTHERN ALABAMA
CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE
VALID 021716Z - 021945Z
PROBABILITY OF WATCH ISSUANCE...40 PERCENT
SUMMARY...A SEVERE THUNDERSTORM WATCH IS BEING CONSIDERED FOR MIDDLE
TENNESSEE INTO PORTIONS OF NORTHERN ALABAMA THIS AFTERNOON IN
ANTICIPATION OF THUNDERSTORMS CAPABLE OF DAMAGING WIND GUSTS.
DISCUSSION...BASED ON THE 12Z OHX SOUNDING AND CURRENT SURFACE
OBSERVATIONS, SURFACE HEATING IS BEGINNING TO REACH AND EXCEED
CONVECTIVE TEMPERATURES ACROSS MUCH OF THE SOUTHEAST. VISIBLE
SATELLITE TRENDS SHOW A CUMULUS FIELD INCREASING IN BOTH EXTENT AND
DEPTH, AND HRRR-BASED MESOANALYSIS SHOWS MLCINH EFFECTIVELY GONE
ACROSS MUCH OF MIDDLE TENNESSEE INTO NORTHERN ALABAMA. WHILE
CONVECTIVE ACTIVITY HAS YET TO DEVELOP, THE EXPECTATION IS THAT
CONVECTIVE INITIATION SHOULD OCCUR BY MID-AFTERNOON. GIVEN STEEP
MID-LEVEL LAPSE RATES FROM THE 12Z OHX SOUNDING (A NEW DAILY MAX
RECORD OF 7.5 C/KM), MODEST PRECIPITABLE WATER CONTENT OF 1.72 IN,
AND GENERALLY WEAK FLOW ALOFT, THUNDERSTORMS WILL BE CAPABLE OF
INTENSE DOWNDRAFTS WITH STRONG TO SEVERE WIND GUSTS. WHILE THE UPPER
FLOW GENERALLY DOESN'T SUPPORT CONVECTIVE ORGANIZATION, STORMS MAY
ORGANIZE ALONG OUTFLOW BOUNDARIES THAT WILL POSE LOCALLY HIGHER
RISKS FOR DAMAGING WINDS. CONDITIONS WILL CONTINUE TO BE MONITORED
FOR A SEVERE THUNDERSTORM WATCH THIS AFTERNOON.
