AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL
644 AM EST MON DEC 13 2010

.AVIATION...
MOSTLY VFR CONDITIONS EXPECTED THROUGH THE FORECAST PERIOD. MAIN
THING TODAY WILL BE BREEZY AND GUSTY CONDITIONS AT TIMES AS WINDS
PICK UP BEHIND THE FRONT. BUT OVERALL WINDS FORECAST TO REMAIN
STEADY AROUND 300 DEGREES WITH WIND SPEEDS TODAY IN THE 15 TO 20
KNOTS RANGE AND GUSTY ACROSS MOST TERMINALS. WINDS ARE EXPECTED TO
DIMINISH TO THE 10 TO 15 KNOTS RANGE BY EARLY TONIGHT.

&&

.PREV DISCUSSION... /ISSUED 527 AM EST MON DEC 13 2010/

DISCUSSION...
THERE ARE NO SIGNIFICANT CHANGES TO THE FORECAST REASONING THIS
MORNING...WITH LATEST WATER VAPOR ANIMATION CONTINUING TO SHOW A
HIGHLY AMPLIFIED UPPER-LEVEL PATTERN IN PLACE ACROSS THE CONUS...
WITH A BROAD MID-LEVEL ANTICYCLONE POSITIONED ACROSS THE WESTERN
HALF OF THE U.S. AND A SHARP UPPER TROUGH CENTERED ACROSS THE
GREAT LAKES REGION. AT THE SURFACE...THE STRONG COLD FRONT WHICH
PASSED ACROSS SOUTH FLORIDA LATE SUNDAY EVENING CONTINUES TO
SPREAD EASTWARD AND IS CROSSING THE CENTRAL BAHAMAS AS OF THIS
WRITING. HOWEVER...THE TRUE ARCTIC AIR MASS -- CHARACTERIZED
PRIMARILY BY DEW POINT TEMPERATURES -- REMAINS CONFINED TO NORTH
FLORIDA AND POINTS FURTHER NORTH ACROSS THE SOUTHEASTERN U.S. ALL
GLOBAL MODELS INDICATE THAT THE HIGHLY DYNAMIC NATURE OF THIS
SYSTEM WILL CONTINUE TO RESULT IN VERY STRONG/GUSTY WEST-
NORTHWESTERLY WINDS TODAY...WHICH SHOULD LIMIT SIGNIFICANT
SOUTHWARD ADVECTION OF THE TRUE ARCTIC AIR TO THE NORTH. A
SCATTERED TO BROKEN DECK OF MARINE LAYER STRATOCU SPREADING
EASTWARD ACROSS THE PENINSULA FROM THE GULF WILL LIKELY HAVE THE
MOST SIGNIFICANT IMPACT ON HIGH TEMPS TODAY...WITH MOST LOCATIONS
LIKELY STRUGGLING TO MAKE IT OUT OF THE 50S. A FEW VERY LIGHT
SHOWERS WILL BE POSSIBLE AS WELL...MAINLY FOR THE GULF WATERS AND
IMMEDIATE GULF COAST BEACH AREAS.

MODELS SUGGEST THAT AS THE UPPER TROUGH OVER NEW ENGLAND BEGINS TO
DEEPEN AND LIFT OUT TO THE NORTHEAST LATE TODAY AND INTO
TONIGHT...GRADIENT WINDS THROUGHOUT THE LOWER TROPOSPHERE WILL
VEER TO THE NORTHWEST...ALLOWING FOR A MUCH STRONGER SOUTHWARD
PLUNGE OF THE TRUE ARCTIC AIR MASS CURRENTLY ENCOMPASSING THE
SOUTHEASTERN STATES. WINDS WILL REMAIN ELEVATED ACROSS THE ENTIRE
AREA OVERNIGHT...AS DEEP MIXING WILL BE ENHANCED BY VERY STRONG
MID-LEVEL SUBSIDENCE OVERSPREADING THE AREA IN THE WAKE OF THE
DEPARTING UPPER LOW...AND THE PRESSURE GRADIENT WILL REMAIN
SUFFICIENTLY STRONG...WITH THE CENTER OF THE ARCTIC SURFACE HIGH
EXPECTED TO REMAIN POSITIONED ACROSS THE MISSISSIPPI VALLEY. THE
LOW-LEVEL THERMODYNAMIC PROFILE ACROSS SOUTH FLORIDA BY SUNRISE
TUESDAY SHOULD BE CHARACTERIZED BY 1000-850 MB THICKNESS VALUES
RANGING FROM 1295-1300 M NEAR THE LAKE TO 1310-1315 M ACROSS FAR
SOUTH MIAMI-DADE COUNTY...WITH DEW POINTS RANGING FROM 10-15 F
ACROSS MUCH OF THE INTERIOR TO 25-30 F ALONG BOTH THE ATLANTIC AND
GULF COAST BEACHES. GIVEN THESE VALUES...THE POTENTIAL DOES EXIST
FOR A WIDESPREAD FREEZE OF HISTORICAL PROPORTIONS...WHICH MAY
EASILY BE MORE SIGNIFICANT THAN THE FREEZE FROM JANUARY 9-11 2010.
THE AMAZING THING TO NOTE IS THAT THIS WILL BE LIKELY BE A PURELY
ADVECTIVE FREEZE. DANGEROUSLY LOW WIND CHILLS ARE A SLAM DUNK FOR
EVERYONE TONIGHT...AND WILL BE UPGRADING TO A WIND CHILL WARNING
FOR ALL ZONES. WILL ALSO BE UPGRADING HARD FREEZE WATCH TO HARD
FREEZE WARNING...AND FREEZE WATCH TO FREEZE WARNING...AND EXPAND
FREEZE WARNING TO INCLUDE EVERY ZONE INCLUDING COASTAL
COLLIER/BROWARD/MIAMI-DADE. DESPITE ABUNDANT SUNSHINE...HIGH
TEMPERATURES WILL BE SLIGHTLY COLDER ON TUESDAY...GIVEN A COLD
START TO THE DAY AND PERSISTENT BUT WEAKER COLD ADVECTION.
ALTHOUGH TEMPERATURES MAY WARM A COUPLE OF DEGREE ALONG THE
IMMEDIATE ATLANTIC COAST ON TUESDAY NIGHT...CONDITIONS APPEAR
FAVORABLE FOR A SIGNIFICANT RADIATION FREEZE FOR MUCH OF THE
INTERIOR AND GULF COAST...AS SURFACE RIDGE BEGINS TO SETTLE ACROSS
NORTH FLORIDA. A SLOW WARMING TREND WILL BEGIN ON WEDNESDAY...BUT
WITH RIDGE POSITIONED NORTH OF THE LOCAL AREA AND LIGHT NORTH
WINDS CONTINUING...DECIDED TO UNDERCUT MOS HIGH TEMPERATURES BY
SEVERAL DEGREES. RECORD LOW MINIMUM AND MAXIMUM TEMPERATURES ARE
FOR THE ENTIRE AREA FOR THE NEXT 4 FORECAST PERIODS...BUT DUE TO
NUMBER OF HEADLINES ALREADY PRESENT...WILL NOT MENTION THIS IN
ZFPMFL.

WILL BE MAKING NO MAJOR CHANGES TO THE EXTENDED PORTION OF THE
FORECAST THIS MORNING...AS IT STILL APPEARS AS IF A WARMING
TREND WILL BECOME MORE ESTABLISHED FROM THURSDAY THROUGH AT LEAST
THE FIRST HALF OF THE WEEKEND. GIVEN PROXIMITY OF SURFACE RIDGE ON
WEDNESDAY NIGHT AND RESIDUAL DRY AIR...TEMPERATURES MAY ONCE AGAIN
COME CLOSE TO FREEZING IN THE LAKE REGION AND THIS WILL HAVE TO BE
WATCHED CAREFULLY. MEDIUM RANGE GUIDANCE FROM THE GFS/ECMWF BOTH
SUGGEST THE RAPID EASTWARD PASSAGE OF A SOUTHERN STREAM VORT MAX
ACROSS THE GULF AND FLORIDA PENINSULA NEXT WEEKEND...WHICH SHOULD
INDUCE CYCLOGENESIS AND RESULT IN A STRONGER NORTHWARD ADVECTION
OF WARM/MOIST AIR ACROSS SOUTH FLORIDA. SHOWER CHANCES WILL
INCREASE FROM FRIDAY INTO SATURDAY AS THIS OCCURS...WITH ANOTHER
STRONG COLD FRONT EXPECTED BY THE END OF NEXT WEEKEND.

MARINE...
GALE WARNING HAS BEEN EXPANDED TO INCLUDE ALL NEAR SHORE &
OFFSHORE ATLANTIC AND GULF MARINE ZONES...WITH SCA NOW ONLY
POSTED FOR LAKE AND BAY. WILL LET GALE EXPIRE BY 12Z TUESDAY AS
NORTHWEST FLOW DIMINISHES TO SCA CRITERIA FOR ALL WATERS. WIND
WILL CONTINUE TO DIMINISH BY LATE TUESDAY...WITH SCA REMAINING
ONLY FOR RESIDUAL HIGH SEAS IN THE GULF STREAM. LIGHT WINDS WILL
LEAD TO IMPROVING CONDITIONS ON ALL WATERS BY MID-WEEK.

FIRE WEATHER...
A VERY DRY ARCTIC AIR MASS WILL SPREAD RAPIDLY INTO SOUTH FLORIDA
OVERNIGHT WITH CRITICAL FIRE WEATHER CONDITIONS A GUARANTEE FOR
ALL AREAS TOMORROW. FIRE WEATHER WATCH WILL NEED TO BE UPGRADED TO
RED FLAG WARNING LATER TODAY. A GRADUAL MODIFICATION IN MOISTURE
WILL BEGIN BY MID-WEEK...ALTHOUGH CRITICAL RH VALUES MAY BE
ACHIEVED IN THE LAKE REGION ONCE AGAIN ON WEDNESDAY AFTERNOON.
