AREAS AFFECTED...PORTIONS OF THE MID-TENNESSEE RIVER VALLEY
CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE
VALID 141843Z - 142015Z
PROBABILITY OF WATCH ISSUANCE...40 PERCENT
SUMMARY...SCATTERED THUNDERSTORMS WILL POSE A RISK FOR DAMAGING WIND
GUSTS THIS AFTERNOON ACROSS PORTIONS OF THE MID-TENNESSEE RIVER
VALLEY
DISCUSSION...AN UPTICK IN CONVECTIVE COVERAGE HAS BEEN NOTED ACROSS
PORTIONS OF THE MID-TENNESSEE RIVER VALLEY OVER THE PAST 30-60
MINUTES WITH A BROKEN BROKEN BAND OF DEVELOPING THUNDERSTORMS NOTED
PER REGIONAL RADAR IMAGERY. THIS ACTIVITY IS OCCURRING ALONG A
REMNANT OUTFLOW BOUNDARY FROM OVERNIGHT CONVECTION IMMEDIATELY
DOWNSTREAM OF A SUBTLE MID-LEVEL MCV. MODESTLY ENHANCED MID-LEVEL
WESTERLY FLOW (30+ KTS SAMPLED ABOVE 1.5-2 KM AGL BY THE HTX VWP AND
40+ KTS SAMPLED BY OHX) IS CONTRIBUTING TO 20-30 KTS OF EFFECTIVE
SHEAR. COUPLED WITH A MODERATELY UNSTABLE ENVIRONMENT IN PLACE AHEAD
OF THESE STORMS, SOME POTENTIAL EXISTS FOR A MARGINALLY MORE
ORGANIZED MULTICELL CLUSTER/BAND TO EVOLVE EASTWARD THIS AFTERNOON,
WITH AN ATTENDANT RISK FOR DAMAGING WIND GUSTS. WATCH ISSUANCE
REMAINS UNCERTAIN AT THIS TIME, BUT A TARGETED SEVERE THUNDERSTORM
WATCH MAY BE CONSIDERED SHOULD A CORRIDOR OF GREATER SEVERE
POTENTIAL BECOME EVIDENT.
