AREAS AFFECTED...CENTRAL GULF COAST

CONCERNING...SEVERE THUNDERSTORM WATCH 81...

VALID 150000Z - 150100Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 81
CONTINUES.

SUMMARY...ISOLATED SEVERE THREAT CONTINUES ALONG THE CENTRAL GULF
COAST.  NEW WW MAY BE CONSIDERED ALONG THE CNTRL GULF COAST IF
CONVECTIVE TRENDS INCREASE WITHIN FAVORABLE AIR MASS.

DISCUSSION...OUTFLOW FROM EARLIER CONVECTION HAS PROGRESSED OFFSHORE
ALONG THE MS/AL COAST.  WITH AN EXPANSIVE AREA OF PRECIPITATION NOW
NOTED ACROSS INTERIOR MS/SRN AL THERE IS LITTLE REASON TO BELIEVE
THIS BOUNDARY WILL RETURN APPRECIABLY NWD...AT LEAST WEST OF THE FL
PANHANDLE.  DOWNSTREAM...MARITIME TROPICAL AIR MASS WILL GRADUALLY
ADVANCE NWD ACROSS THE FL PANHANDLE WITH NEAR 70 SFC DEW POINTS
EXPECTED TO SPREAD SLOWLY NWD AHEAD OF APPROACHING MCS.  AT TIMES
VARIOUS SHEAR COUPLETS HAVE FORMED IN ASSOCIATION WITH SMALL
SUPERCELLS OFFSHORE BUT UPDRAFTS HAVE STRUGGLED TO MAINTAIN THEIR
STRUCTURES AS THEY LIFT NORTH OF THE BARRIER ISLANDS.  WILL CONTINUE
TO MONITOR THERMODYNAMIC CHANGES ALONG THE COAST AND UNTIL MORE
BUOYANT AIR MASS CAN SPREAD INLAND SEVERE THREAT SHOULD REMAIN
ISOLATED.
