THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH
76...77...CONTINUES.

SUMMARY...DISCRETE SUPERCELL ALONG THE BORDER OF WW/S 76/77 SHOULD
CONTINUE TO RAPIDLY WEAKEN WITH RE-INTENSIFICATION NOT EXPECTED.

DISCUSSION...A PREVIOUSLY INTENSE SUPERCELL WITH A HISTORY OF
PRODUCING VERY LARGE HAIL HAS WEAKENED SUBSTANTIALLY IN THE PAST
20-30 MINUTES. THIS IS LIKELY OWING TO RAPIDLY INCREASING MLCIN /AS
SAMPLED BY 00Z CRP AND BRO RAOBS/ AND INFERRED BY GROUND CLUTTER
PATTERN FROM BRO RADAR. SUCH A STRONG CAPPING INVERSION IN THE
ABSENCE OF LARGER-SCALE ASCENT SHOULD RESULT IN RAPID DEMISE OF THIS
SUPERCELL BETWEEN 03-04Z.
