AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MELBOURNE FL
325 AM EST THU JAN 22 2009

.DISCUSSION...

...FREEZING TEMPS FOR MUCH OF THE AREA AGAIN TONIGHT ALONG WITH
WIDESPREAD FROST...

CURRENTLY...HIGH PRESSURE CONTINUES TO BUILD IN FROM THE WEST AND
MOST OF THE AREA HAS HAD TEMPS BELOW FREEZING. FAWN OBSERVATIONS
SHOW WIDESPREAD MID 20S ACROSS THE NORTH. WHILE WINDS OVERALL ARE
VERY LIGHT...SOME SLIGHT BOUNDARY LAYER FLOW HAS LED TO TEMPS
OSCILLATING UP AND DOWN.

TODAY-TONIGHT...THERE HAS BEEN LITTLE CHANGE WITH THE MODELS
SHOWING A HIGH PRESSURE CENTER SETTLING OVER THE CENTRAL
PENINSULA. THE AIR MASS WILL GRADUALLY MODIFY AND MAX TEMPS SHOULD
BE 5-10 DEGREES WARMER THAN YESTERDAY...BUT STILL WELL BELOW
NORMAL IN THE UPPER 50S NORTH TO MID 60S FAR SOUTH.

EXPECT EVEN BETTER RADIATIONAL COOLING CONDITIONS TONIGHT WITH
LITTLE/NO BOUNDARY LAYER FLOW AND CONTINUED CLEAR SKIES. MOS
CONTINUES TO SHOW MINS IN THE UPPER 20S ACROSS THE NORTH.
THEREFORE THE PREVIOUS FREEZE WATCH WILL BE UPGRADED TO A FREEZE
WARNING.

ADDITIONALLY...GUIDANCE IS SHOWING A PORTION OF THE SOUTH WITH
MIN TEMPS AROUND 30 TO THE LOWER 30S. SINCE THE SURFACE HIGH WILL
BE PERCHED OVER OUR AREA...HAVE OPTED TO EXTEND THE FREEZE
WARNING SOUTHWARD TO OKEECHOBEE...INCLUDING THE SPACE COAST AND
PORTIONS OF THE TREASURE COAST. THE FREEZING TEMPS ALONG THESE
COASTS WILL BE INLAND.

MOS IS SHOWING HIGHER RH VALUES TONIGHT...SO MORE WIDESPREAD FROST
IS ANTICIPATED. A LIGHT ONSHORE WIND COMPONENT SHOULD DEVELOP NEAR
THE COAST THIS AFTERNOON...WHICH WILL RAISE DEW POINTS...SO THE
WIDESPREAD INLAND FROST MIGHT EXTEND ALL THE WAY BACK TO THE
INTRACOASTAL.

FRI-SAT...HIGH PRESSURE WILL REMAIN CENTERED OVER THE PENINSULA.
GOOD RADIATIONAL COOLING FORECAST EACH NIGHT WITH NEAR CALM WIND
AND FEW CLOUDS. TEMPS ALTHOUGH ABNORMALLY COLD SHOULD REMAIN ABOVE
FREEZING FRI NIGHT OVER ALL OF THE AREA WITH PATCHY FROST AND
CLOSER TO SEASON NORMS BY SATURDAY. RIDGE FORECAST TO BREAK DOWN
BY SATURDAY NIGHT IN RESPONSE TO FALLING HEIGHTS NORTH OF THE
AREA.

SUN-WED...LIGHT WINDS SUNDAY AS A WEAK COLD FRONT MOVES TOWARD
THE STATE. QUESTIONABLE MOISTURE RETURN AHD OF THIS FEATURE KEEPS
ANY MENTIONABLE POPS OUT OF THE FORECAST FOR NOW WITH FRONT SHOWN
ONLY MAKING LIMITED PROGRESS INTO THE AREA. WEAK LOW DEVELOPMENT
EAST OF STATE INDICATED BY GFS/ECM EARLY MON AND INTO TUE MAY
PRODUCE A SHOWER CHC MAINLY OVER THE MARINE AREA SUN/MON. STABLE
NE FLOW EARLY IN THE WEEK WL PRODUCE LITTLE SIG WEATHER.

&&

.AVIATION...VFR.

&&

.MARINE...THROUGH TONIGHT THE WINDS WILL BE LIGHT. AN EAST/NORTHEAST
SWELL AT 11-12 SECONDS WILL KEEP SEAS 3-5 FEET OFFSHORE.

WITH HIGH PRESSURE SETTLING OVER THE AREA SEAS WL SHOW CONTINUED
IMPROVEMENT FRIDAY THROUGH THE WEEKEND. NE FETCH EARLY NEXT WEEK
WILL INCREASE SEA HEIGHTS AND HEADLINES MAY BE REQUIRED OVER THE
OUTER WATERS.

&&

.FIRE WEATHER...HIGHER TEMPS TODAY WILL OFFSET A SLIGHT RISE IN
DEW POINTS SO MIN RH VALUES SHOULD FALL INTO THE 20S FOR MOST OF
THE AREA...AND A FEW SPOTS AGAIN SHOULD FALL BELOW 20 PERCENT. SO
LONG DURATIONS OF LOW RH WILL EASILY VERIFY RED FLAG WARNING.

CRITICALLY DRY AFTERNOON CONDITIONS WILL CONTINUE FRIDAY WITH LONG
DURATION OF LOW AFTERNOON RH. INCREASING DEW POINTS EXPECTED
SATURDAY AND WITH APPROACH OF FRONT BY SUNDAY INTO EARLY NEXT
WEEK.
