BIMODAL ASCENT PLUMES ARE CONVERGING ON THE FL PENINSULA THIS
AFTERNOON.  MAIN UPSTREAM BAROCLINIC ZONE IS SHIFTING EWD ACROSS THE
FL PANHANDLE WITH A NARROW BAND OF BROKEN CONVECTION...AND ISOLATED
THUNDERSTORMS ALONG THE GA/AL BORDER.  THIS ACTIVITY TRAILS INTO THE
NERN GULF WHERE NEW THUNDERSTORMS MAY YET DEVELOP OVER THE NEXT FEW
HOURS.

SECONDARY HIGHER MOISTURE CONTENT PLUME OF ASCENT IS RESPONSIBLE FOR
CONSIDERABLE AMOUNT OF CONVECTION AND SCATTERED THUNDERSTORMS FROM
THE SRN HALF OF THE FL PENINSULA...SWWD INTO THE FL STRAITS.  HIGHER
INSTABILITY IS NOTED ACROSS THIS REGION...HOWEVER WEAK LAPSE RATE
ENVIRONMENT AND MARGINAL DEEP LAYER SHEAR WILL PREVENT ANY
MEANINGFUL THREAT FOR SEVERE THUNDERSTORMS THIS PERIOD.  NRN
PORTIONS OF THIS CONVECTION MAY EXPAND IN AREAL COVERAGE AS UPSTREAM
TROUGH AFFECTS NRN FL LATE IN THE PERIOD.

...PACIFIC NW...

ISOLATED THUNDERSTORMS MAY YET DEVELOP ALONG THE WA/ORE COAST AS
UPPER RIDGE SHIFTS INLAND AND SECONDARY ZONE OF LOW LEVEL
CONVERGENCE APPROACHES THE AREA.  THIS ACTIVITY WILL REMAIN WEAK AND
SHALLOW...HEAVILY INFLUENCED BY MARINE LAYER INSTABILITY.
