ACTIVITY NOW FIRING RATHER EARLY ALONG GULF COAST AS WCSB PUSHES
ONSHORE...IN FACT SOME OF THE TSTM OVER PINELLAS CNTY WERE HEAVY
ENOUGH TO REQUIRE AN URBAN FLOOD ADVISORY.

OVER THE LAST FEW DAYS I HAVE FAVORED A AVN/NGM BLEND AS MODEL OF
CHOICE. HOWEVER...12Z AVN RUN IS SUSPECT WITH IT'S DEEPENING OF THE
LOW ASSOCIATED WITH EAST COAST COLD FRONT LATE IN THE PD. WILL DROP
BACK TO THE NGM-ETA. BROAD H5 RDG OVER SOUTHERN CONUS SLIDES WEST
AND BUILD OVER THE SOUTHERN PLAINS WITH FLOW ALOFT BACKING FROM NE TO
NORTHERLY ACROSS THE SOUTHEAST U.S. WHICH WILL HELP SLIDE A SURFACE
RIDGE AXIS FROM NORTH FL INTO SOUTH FL THURSDAY AND A WEAK FRONT/
WITH A SFC LOW OVR THE ATLANTIC INTO NORTH FL FRI. AS THE RDG MOVES
OVER THE CWFA WINDS WILL SHIFT FROM VARIABLE TO WESTERLY FOR AREA
BEGINNING THURSDAY AND INTO FRIDAY. IN THIS FLOW PATTERN PCPN WILL
SHIFT FROM AFTERNOON/EARLY EVENING( FOR TODAY) TO MORNING ACTIVITY
ALONG GULF COAST THAT PUSHES INLAND DURING THE DAY. BETWEEN WESTERLY
FLOW AND RDGG ALOFT WOULD EXPECT SLIGHTLY WARMER TEMPS SO WILL BUMP
UP FWC TEMPS( WHICH HAVE BEEN DOING FINE ) 1-2 DEG. PWATS FOR
SOUTH AND CENTRAL AREAS REMAIN IN THE 1 3/4 TO 2 IN RANGE WHILE THE
NORTH WHICH IS IN DRYER AIR( AS NOTED ON THE STLT WATER VAPOR )
INCREASES TO ABOUT 2 IN EARLY FRI AS THE FRONT DROPS IN THE NORTHERN
PART OF THE STATE. THIS WILL SUPPORT SCATTERED PCPN(30-50%) WITH
COVERAGE AS NOTED EARLIER( MORNING COAST MOVING INTERIOR AFTERNOON).

IN THE EXTENDED...LATE SEASON FRONTAL SYSTEM EXPECTED TO MOVE DOWN
THE STATE LATE FRI/EARLY SAT WITH HIGH PRESS BUILDING IN FROM LATE
SAT INTO MON. WILL GENERALLY STAY CLOSE TO MRF AND PREVIOUS SHIFT'S
EXTENDED FCST.

THANKS FOR COORD MLB.
