VALID 080826Z - 080930Z

ORGANIZED SEVERE WEATHER THREAT APPEARS TO BE DIMINISHING AND WW 139

AS OF 0810Z...REGIONAL RADAR IMAGERY SHOWED TRAILING PORTION OF
QUASI-LINEAR MCS ORIENTED WSW-ENE ACROSS FAR SRN FL PENINSULA FROM
NEAR MIA TO APPROXIMATELY 60 WSW MIA. THOUGH A FEW BOWING STRUCTURES
HAVE BEEN OBSERVED WITHIN CONVECTIVE LINE OVER THE PAST HOUR OR
SO...SURFACE OBSERVATIONS INDICATE THAT SYSTEM COLD POOL HAS SURGED
AHEAD OF MAIN CONVECTIVE UPDRAFTS BY 10-15 MILES. THIS SUGGESTS THAT
MAJORITY OF ONGOING ACTIVITY IS LIKELY SLIGHTLY ELEVATED ABOVE COLD
POOL...EFFECTIVELY REDUCING DAMAGING WIND THREAT. POTENTIAL FOR
ISOLATED HAIL/DAMAGING WINDS IS EXPECTED TO PERSIST FOR THE NEXT FEW
HOURS AS MCS SHIFTS SWD ACROSS REMAINDER OF S FL AND THE KEYS.
