VALID 172205Z - 172330Z

ISOLATED SEVERE POTENTIAL MAY CONTINUE FOR A COUPLE MORE HOURS

LATEST OBJECTIVE ANALYSIS REVEALS MODEST /AOB 1000 J/KG/ MIXED-LAYER
CAPE ACROSS THE MID MS VALLEY REGION...WHERE ISOLATED THUNDERSTORMS
CONTINUE.  ONE STRONGER CELL -- NOW MOVING ACROSS NWRN TN -- IS
OCCURRING JUST SOUTHEAST OF A SMALL MID-LEVEL VORT MAX NOW CROSSING

IMAGERY.  THIS STORM APPEARS CAPABLE OF PRODUCING DAMAGING WINDS

MARGINAL SEVERE WEATHER IN THE NEXT HOUR OR TWO.

OVERALL HOWEVER...EXPECT SEVERE POTENTIAL TO BEGIN TO DIMINISH THIS
EVENING...AS BOUNDARY-LAYER COOLING YIELDS AND OVERALL DECREASE IN
AVAILABLE INSTABILITY -- AND THUS SEVERE POTENTIAL.
