AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL
258 PM EDT THU MAR 18 2010

.DISCUSSION...
RECENT VISIBLE SATELLITE ANIMATION SUGGESTS AN INCREASING TREND IN
THE COVERAGE OF MID AND HIGH-LEVEL CLOUDS ACROSS SOUTH FLORIDA
THIS AFTERNOON...IN ADVANCE OF A POTENT MID-LEVEL VORT MAX
PIVOTING SOUTHEASTWARD AROUND AN UPPER LOW ANCHORED OVER COASTAL
PORTIONS OF SOUTH CAROLINA. THIS FEATURE IS EXPECTED TO RESULT IN
MOSTLY CLOUDY CONDITIONS THROUGH MID TO LATE EVENING...BEFORE IT
EJECTS RAPIDLY EAST-NORTHEASTWARD ACROSS THE ATLANTIC LEAVING A
CLEARING TREND IN ITS WAKE. THE COMBINATION OF CLEARING SKIES AND
SURFACE RIDGE APPROACHING FROM THE WEST WILL ALLOW FOR GOOD
RADIATIONAL COOLING CONDITIONS TONIGHT...WITH LIGHT OFFSHORE
DRAINAGE FLOW LEADING TO A COOL MORNING ALONG BOTH COASTS. ASIDE
FROM ISOLATED LIGHT SHOWER ACTIVITY LATE THIS AFTERNOON AND EARLY
THIS EVENING...EXPECT DRY WEATHER AND A GRADUAL WARMING TREND TO
PREVAIL THROUGH THE REMAINDER OF THE SHORT TERM PERIOD...AS MID-
LEVEL SHORTWAVE RIDGE WILL BUILD OVERHEAD DOWNSTREAM FROM UPPER-
LEVEL TROUGH MOVING FROM THE FOUR CORNERS REGION TO THE SOUTHERN
PLAINS...AND PWAT VALUES WILL REMAIN BELOW 0.75 INCHES. LIGHT
EASTERLY RETURN FLOW WILL BEGIN BY FRIDAY NIGHT...AS SURFACE RIDGE
MOVES EASTWARD INTO THE ATLANTIC. THUS...EXPECT A MORE PRONOUNCED
WARMING TREND TO BEGIN ON SATURDAY...WITH DEEP-LAYER MOISTURE ALSO
INCREASING FROM SATURDAY NIGHT INTO SUNDAY AS SOUTHERLY LOW-LEVEL
JET STRENGTHENS IN ADVANCE OF APPROACHING UPPER LOW.

IN THE EXTENDED FORECAST...WILL MAKE NO CHANGES AT THIS
TIME...WITH RAIN CHANCES STILL APPEARING TO INCREASE ON SUNDAY
AFTERNOON IN STRONG WARM ADVECTION REGIME AHEAD OF APPROACHING
COLD FRONT. THE GFS AND ECMWF CONTINUE TO COME INTO BETTER
AGREEMENT ON TIMING OF THE COLD FRONT...WITH FRONT EXPECT TO PASS
ACROSS THE AREA ON SUNDAY NIGHT OR MONDAY MORNING. SHOWER ACTIVITY
WILL INCREASE IN ADVANCE OF THIS FEATURE...WITH MODELS ALSO
INDICATING A FAIR AMOUNT OF POSTFRONTAL PRECIPITATION AS WELL. DRY
AND WARMER WEATHER EXPECTED FROM TUESDAY THROUGH THURSDAY AS
EASTERLY FLOW RETURN AS THE SURFACE AND NORTHERN PERIPHERY OF
SUBTROPICAL RIDGE BUILDS NORTHWARD ACROSS THE AREA.

.MARINE...
SCA FOR THE ATLANTIC WATERS WILL CONTINUE FOR STRONG/GUSTY WEST
WINDS. NORTHEAST SWELL WILL ALSO CONTINUE TO AFFECT THE ATLANTIC
