AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL
629 AM EST THU DEC 20 2012

.AVIATION...
WEAK SFC HIGH PRESSURE OVER SOUTH FLORIDA KEEPING FAIR CONDITIONS
ACROSS THE AREA WITH VFR CONDITIONS TO PREVAIL THROUGH THIS
EVENING. STILL COULD SEE A BRIEF VSBY REDUCTION AT KAPF AND KTMB
DUE TO FOG EARLY THIS MORNING, BUT WINDOW OF TIME IS RUNNING OUT
AS WE APPROACH 12Z. PREVAILING SE FLOW TODAY EXCEPT GRADUALLY
VEERING TO S-SW AT KAPF AROUND 19Z. STRONG COLD FRONT WILL MOVE
INTO SOUTH FLORIDA AT TAIL-END OF THIS FORECAST PERIOD, WITH A
BROKEN AND WEAK BAND OF SHOWERS. CEILINGS COULD BECOME AN ISSUE
ALONG AND IMMEDIATELY BEHIND THE FRONT, ALONG WITH SHIFT TO GUSTY
NORTH WINDS. SUBSEQUENT FORECASTS TODAY WILL FINE-TUNE TIMING AND
CONDITIONS ASSOCIATED WITH THE FRONT. /MOLLEDA

&&

.PREV DISCUSSION... /ISSUED 342 AM EST THU DEC 20 2012/

..TURNING MUCH COLDER FRIDAY THROUGH THE WEEKEND...
..HAZARDOUS MARINE CONDITIONS OVER LOCAL WATERS LATE TONIGHT THROUGH SATURDAY...

SHORT TERM (TODAY THROUGH SATURDAY)...
WATER VAPOR IMAGERY AND NAM ANALYSIS FROM THIS MORNING SHOWED AN
UPPER LEVEL RIDGE OVER THE EASTERN CONUS AND THE FLORIDA
PENINSULA...A SHORTWAVE TROUGH OVER THE CENTRAL PLAINS AND ANOTHER
RIDGE OVER THE ROCKIES. VERY DRY MID LEVEL AIR WAS ALSO LOCATED
OVER THE REGION. AT THE SURFACE...HIGH PRESSURE WAS LOCATED OVER
THE WESTERN ATLANTIC...PROVIDING A LIGHT EAST TO SOUTHEAST FLOW
OVER SOUTH FLORIDA. LOW PRESSURE WAS DEVELOPING OVER SOUTHERN
MISSOURI...AND STRONG HIGH PRESSURE WAS LOCATED OVER UTAH AND
COLORADO.

LOW PRESSURE WILL CONTINUE TO DEEPEN AS IT MOVES NORTHEAST INTO
ILLINOIS AND THEN SOUTHERN MICHIGAN. TODAY WILL BE THE LAST WARM
DAY THIS WEEK FOR SOUTH FLORIDA. HIGH TEMPS IN THE LOWER 80S
THIS AFTERNOON WILL BE SEVERAL DEGREES ABOVE NORMAL. A STRONG COLD
FRONT WILL MOVE INTO NORTH FLORIDA BY THIS EVENING...WITH SURFACE
WINDS ACROSS THE REGION BEGINNING TO VEER TO THE SOUTH AND
SOUTHWEST. THE MOISTURE ALONG THE FRONT WILL STRETCH AND THIN OUT
AS IT APPROACHES SOUTH FLORIDA...AND THE BEST DYNAMICS WILL REMAIN
WELL TO THE NORTH. WITH THE THINNING MOISTURE FIELD...VEERING WIND
PROFILE AND THE FRONT EXPECTED TO PASS THROUGH THE REGION
OVERNIGHT INTO THE MID MORNING HOURS FRIDAY...ONLY EXPECT A DYING
LINE OF SHOWERS TO MOVE THROUGH SOUTH FLORIDA. THE BEST CHANCE OF
RAIN WILL BE ACROSS THE GULF COAST AND NORTHWEST INTERIOR...WITH
LOWER CHANCES SOUTH AND EAST. THE FRONT SHOULD COMPLETELY CLEAR
THE REGION BEFORE NOON ON FRIDAY.

STRONG COLD AIR ADVECTION WILL OCCUR IN THE WAKE OF THE
FRONT...WITH DAYTIME TEMPERATURES RISING IN THE MORNING AND THEN
REMAINING STEADY OR EVEN FALLING DURING THE AFTERNOON.
TEMPERATURES WILL REMAIN IN THE MID 60S ACROSS THE NORTHERN HALF
OF THE REGION...WITH LOW 70S ELSEWHERE. COLD AIR ADVECTION WILL
CONTINUE FRIDAY NIGHT WITH NORTH TO NORTHWESTERLY WINDS AS HIGH
PRESSURE MOVES EAST ALONG THE NORTHERN GULF COAST. 1000-850MB
THICKNESS VALUES WILL ONLY BE AROUND 1348-1358 DECAMETERS BY
SATURDAY MORNING...WHICH IS USUALLY NOT THAT IMPRESSIVE. THE HIGH
ITSELF IS ALSO NOT STRONG ENOUGH TO ALLOW FOR AN ADVECTION FREEZE.
HOWEVER...THE AIRMASS WILL BE INCREDIBLY DRY BEHIND THE
FRONT...WITH PRECIPITABLE WATER VALUES FALLING BELOW A QUARTER OF
AN INCH...AND POSSIBLY LESS THAN ONE TENTH OF AN INCH ACROSS THE
NORTHWEST INTERIOR. THIS WILL ALLOW DEWPOINTS TO PLUMMET
THROUGHOUT THE DAY ON FRIDAY AND INTO THE NIGHT. TEMPERATURES WILL
FOLLOW SUIT...WITH LOWS IN THE MID 30S WEST OF LAKE
OKEECHOBEE...LOW 40S FOR THE WEST PALM BEACH AND NAPLES
REGIONS...AND MID 40S TO AROUND 50 DEGREES FOR THE FORT LAUDERDALE
AND MIAMI REGION. IF WINDS DECOUPLE NEAR THE LAKE...SOME OF THE
NORMALLY COLDER LOCATIONS COULD POSSIBLY SEE TEMPERATURES AT OR
BELOW FREEZING. AT THIS TIME...GUIDANCE KEEPS WINDS UP ENOUGH THAT
TEMPERATURES WOULD REMAIN JUST ABOVE THE FREEZING MARK...BUT WIND
CHILLS WOULD BE IN THE UPPER 20S. SO WILL NOT ISSUE A FREEZE WATCH
AT THIS TIME. WINDS OF 10-15 MPH ARE EXPECTED NEAR THE COASTS. SO
TEMPERATURES WILL FEEL MUCH COLDER THAN THE AIR TEMPERATURE.
APPARENT TEMPERATURES IN THE UPPER 20S TO LOW 30S ARE POSSIBLE FOR
A LARGE AREA OF INLAND SOUTH FLORIDA...INCLUDING GLADES AND HENDRY
COUNTIES...INLAND COLLIER AND INLAND PALM BEACH COUNTY. APPARENT
TEMPERATURES IN THE MID 30S TO MID 40S ARE POSSIBLE
ELSEWHERE..HIGHEST FOR THE METRO AND COASTAL AREAS OF MIAMI DADE
COUNTY.
