AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MELBOURNE FL
1000 AM EST WED JAN 22 2014

.DISCUSSION...

...MUCH COOLER TODAY WITH FREEZING TEMPERATURES LIKELY TONIGHT...

STRONG COLD AND DRY AIR ADVECTION GOING IN EARNEST ACROSS THE
CENTRAL FLORIDA PENINSULA UNDER 10 TO 15 MPH NORTHWEST WINDS.

DESPITE FULL SUN UNDER CLEAR SKIES (EXCEPT FOR COLD AIR STRATOCU
OVER THE OPEN ATLANTIC)...THE COLD AIR ADVECTION WILL WIN OUT
KEEPING DAYTIME HIGHS IN THE 50S FOR MOST LOCATIONS. THE TREASURE
COAST AND OKEECHOBEE COUNTY WILL BE AMONG THE FEW THAT CLIMB INTO
THE LOW 60S THIS AFTERNOON.

TONIGHT...THE MAIN FORECAST CHALLENGE TONIGHT WILL CONTINUE TO BE
THE FREEZE POTENTIAL ACROSS THE REGION.

SURFACE HIGH MOVING INTO THE GULF OF MEXICO THIS AFTERNOON WILL
WEAKEN AS IT MOVES OVER THE PENINSULA TONIGHT...BUT WE WILL STILL BE
UNDER THE INFLUENCE OF THE RIDGE AXIS ALLOWING WINDS TO BECOME CALM
(OR NEARLY SO) QUICKLY AFTER SUNSET. HOWEVER MODELS ARE SHOWING THE
CIRRUS CURRENTLY BACK OVER THE SW US STREAMING ACROSS THE STATE LATE
TONIGHT. THE DEPICTIONS RANGE FROM THE MORE ROBUST 00Z GFS TO THE
ALMOST NON-EXISTENT 12Z NAM. IT APPEARS THAT WE MAY HAVE A CASE
WHERE TEMPERATURES DROP RAPIDLY AFTER SUNSET...AND THEN STABILIZE AS
SOME DEGREE OF CIRRUS MOVES OVERHEAD.

GIVEN THE MOS GUIDANCE FROM PREVIOUS RUNS ARE RIGHT AROUND FREEZING
AND THE UNCERTAINTY OF CLOUD COVER WILL MEAN A FEW DEGREES EITHER
WAY...WILL HOLD OFF UNTIL THE 12Z GUIDANCE COMES IN AROUND MIDDAY TO
MAKE THE FINAL DECISION ABOUT UPGRADES TO A FREEZE WARNING AND ITS
EXTENT.

REGARDLESS OF WHETHER OR NOT A WARNING IS IN PLACE...LOWS IN THE
LOW/MID 30S WILL ALLOW FOR FROST DEVELOP OVER MUCH OF THE REGION AND
AT LEAST A FEW LOCATIONS WILL REACH FREEZING.

&&

.AVIATION...VFR CONDS NEXT 24 HOURS. NW WINDS AROUND 10-15 KTS WILL
BECOME W/NW AND DECREASE TO 5 KNOTS OR LESS TONIGHT.

&&

.MARINE...C-MAN OBSERVATIONS ALONG THE COAST INDICATE THAT THE
NEARSHORE WINDS HAVE DROPPED BELOW ADVISORY CRITERIA THIS MORNING
ALONG WITH THE WEAKENING MODEL TRENDS...POINT TO WINDS AROUND
15-20KTS THIS MORNING BECOMING 10-15KTS THIS AFTERNOON.
OFFSHORE...OBSERVATIONS STILL SHOW ADVISORY CRITERIA WITH WINDS
20-25KTS...WHICH WILL DROP OFF LATER THIS AFTERNOON TO 15-20 KNOTS.

SEAS UP TO 7-9 FEET OFFSHORE INITIALLY WILL ALSO DECREASE TO 6-7
FEET LATE TODAY. WILL DROP ADVISORY OVER THE NEARSHORE WATERS IN
FAVOR OF A CAUTIONARY STATEMENT BUT KEEP IT IN PLACE FOR THE
OFFSHORE WATERS THROUGH THIS AFTERNOON.

&&

.FIRE WEATHER...A MUCH DRIER AIRMASS IN PLACE OVER THE AREA TODAY
BEHIND THE COLD FRONT WITH MIN RH VALUES IN THE 20S TO LOW 30S
ACROSS THE REGION FROM LATE MORNING THROUGH THIS AFTERNOON. HOWEVER
20FT WIND SPEEDS LESS THAN 15 MPH AND ERC VALUES BELOW CRITICAL
THRESHOLDS WILL PRECLUDE THE ISSUANCE OF A RED FLAG WARNING TODAY.
