NATIONAL WEATHER SERVICE MELBOURNE FL
920 AM EST WED FEB 4 2009

.DISCUSSION...

...A HARD FREEZE EXPECTED ACROSS MOST OF EAST CENTRAL FLORIDA
TONIGHT...
...DANGEROUSLY COLD WIND CHILLS OVERNIGHT AND EARLY THURSDAY...

ARCTIC AIR SPILLING SOUTHWARD INTO THE STATE WITH UPSTREAM AIRMASS
VERY DRY ON MORNING SOUNDINGS. FULL MIXING BY LATE THIS MORNING WILL
PRODUCE GUSTY WINDS THROUGH THE AFTERNOON. TEMPERATURES WILL REMAIN
ONLY IN THE 40S ACROSS NORTH LAKE AND VOLUSIA COUNTIES AND LOWER TO
MID 50S ACROSS AREA.

FORECAST REMAINS ON TRACK AND WILL EVALUATE WIND AND VERY LOW TEMP
COMBINATIONS EXPECTED TONIGHT. TONIGHTS COLD WILL BE AGGRAVATED BY
THE CONTINUATION OF WIND WHICH WILL PRODUCE SELDOM EXPERIENCED WIND
CHILL READINGS FOR THIS AREA.

** PREV DISC**

TONIGHT...STRONG COLD AIR ADVECTION WILL CONTINUE TONIGHT...925 MB
FREEZING LINE PUSHES SOUTH OF LAKE OKEECHOBEE BY DAYBREAK. SINCE
THIS WILL BE AN ADVECTIVE FREEZE...HAVE GONE 1-2 DEGREES HIGHER
THAN GFS MOS ON TEMPS SINCE MOS TENDS TO BE TOO COLD IN THESE
SITUATIONS. BUT THIS STILL FORECASTS A HARD FREEZE ACROSS MUCH OF
EC FL...WITH MIN TEMPS IN THE MID TO UPPER 20S. HAVE POSTED A HARD
FREEZE WARNING ALL AREAS...WITH THE EXCEPTION OF BARRIER ISLANDS
FROM BREVARD COUNTY SOUTHWARD TO MARTIN COUNTY (WHERE A FREEZE
WARNING IS IN EFFECT). MIN TEMPS ALONG THE TREASURE COAST WILL BE
IN THE LOWER 30S.

NW GRADIENT WIND WILL SUPPORT 10-15 MPH WINDS OVERNIGHT WHICH...
COMBINED WITH SUCH COLD TEMPS...COULD PRODUCE DANGEROUSLY COLD
WIND CHILLS IN THE TEENS ACROSS MUCH OF THE AREA LATE TONIGHT AND
EARLY THURS. HAVE THEREFORE RAISED A WIND CHILL WATCH ALL
COUNTIES. THIS WATCH WILL EITHER BE UPGRADED TO A WIND CHILL
WARNING LATER TODAY OR REPLACED BY A WIND CHILL ADVISORY.

THU-THU NIGHT...A COLD DAY IN STORE AS HIGH TEMPERATURES WILL ONLY
TOP OUT IN THE LOWER 50S NORTH AND UPPER 50S SOUTH. HIGH PRESSURE
WILL CONTINUE TO GRADUALLY BUILD INTO THE SOUTHEAST U.S. WITH A
SLOWLY DIMINISHING PRESSURE GRADIENT. NORTHERLY WINDS WILL STILL BE
10-15 MPH OVER THE INTERIOR AND AROUND 15 MPH ALONG THE EAST COAST.
A FAVORABLE NIGHT FOR RADIATIONAL COOLING WILL BE SET AS SKIES
REMAIN CLEAR...WINDS BECOME LIGHT NORTHERLY 5 MPH OR LESS AND
TEMPERATURES FALL INTO THE UPPER 20S ACROSS INLAND VOLUSIA AND LAKE
COUNTIES AND NEAR TO JUST BELOW FREEZING ALONG AND SLIGHTLY SOUTH OF
THE I-4 CORRIDOR. LOWER TO MIDDLE 30S EXPECTED SOUTH THROUGH
OKEECHOBEE AND INTERIOR COASTAL COUNTIES THROUGH INDIAN RIVER AND
ST. LUCIE. MARTIN COUNTY SHOULD REMAIN IN THE UPPER 30S INTERIOR TO
MIDDLE 40S NEAR THE COAST. AS A RESULT EXPECT AREAS OF FROST TO
DEVELOP OVER MUCH OF EAST CENTRAL FLORIDA. A FREEZE WATCH WILL
LIKELY BE NECESSARY MAINLY ALONG AND NORTH OF THE I-4 CORRIDOR FOR
THU NIGHT/EARLY FRI MORNING.

FRI-FRI NIGHT...NOT MUCH HAS CHANGED OVER THE LAST 24 HOURS FOR THIS
PERIOD AS HIGH PRESSURE GRADUALLY MOVES OFF OF THE SOUTHEAST U.S.
COAST WITH RIDGE AXIS EXTENDING WESTWARD ACROSS SOUTHERN GA &
NORTHERN FL. AN ONSHORE COMPONENT OF WIND WILL DEVELOP WITH
TEMPERATURES AND DEWPOINT READINGS MODERATING BACK UP. STILL EXPECT
MOSTLY SUNNY SKIES DURING THIS TIME. HIGHS MAINLY IN THE LOWER TO
MIDDLE 60S WITH A FEW UPPER 60S POSSIBLE FAR SOUTH. LOWS FRI
OVERNIGHT COMING IN A BIT COLDER...HOWEVER...WITH UPPER 30S NORTH
AND NORTHWEST INTERIOR AND MAINLY IN THE 40S FURTHER SOUTH EXCEPT
LOWER/MIDDLE 50S ALONG THE IMMEDIATE TREASURE COAST OF ST. LUCIE
AND MARTIN COUNTIES.

SAT-WED...ONSHORE FLOW CONTINUES ACROSS EAST CENTRAL FLORIDA THROUGH
THIS EXTENDED PERIOD AS HIGH PRESSURE SLOWLY BREAKS DOWN AND MOVES
FURTHER INTO THE WESTERN ATLC. ANOTHER COLD FRONT WILL APPROACH THE
SOUTHEASTERN U.S. LATE IN THE PERIOD...THOUGH WILL CONTINUE TO KEEP
CONDITIONS DRY THROUGHOUT. HIGHS/LOWS WILL CONTINUE TO MODERATE BACK
UP WITH NORMAL CLIMO TEMPERATURES EXPECTED BY SUN LASTING INTO WED
OF NEXT WEEK. AS MOISTURE INCREASES THROUGH THIS TIME EXPECT TO SEE
A BIT MORE IN THE WAY OF DAYTIME FAIR WEATHER CLOUDS EACH DAY.

&&

.AVIATION...VFR. GUSTY NW WINDS UP TO 25 KNOTS.

&&

.MARINE...
TODAY...PRES GRAD IS TIGHTENING BACK UP AS EXPECTED AND SOLID
ADVISORY CONDITIONS ARE (RE)OCCURRING ACROSS THE ATLC WATERS...
THOUGH OFFSHORE COMPONENT IS KEEPING SEAS SUPPRESSED NEAR THE
COAST. STRONG COLD ADVECTION WILL OVERSPREAD THE WATERS BEHIND A
COLD FRONT THIS MORNING PRODUCING VERY GUSTY CONDITIONS...WITH
OCCASIONAL GUSTS TO GALE FORCE OFFSHORE.

THU-THU NIGHT...HIGH PRESSURE BUILDS SLOWLY SOUTH AND SETTLES IN
ACROSS SOUTHERN GA & NORTHERN FL. THE PRESSURE GRADIENT WITH
NORTH-NORTHWEST WINDS (OFFSHORE) STILL FORECAST TO DECREASE TO 15-20
KTS BY LATE AFTERNOON AND 10-15 KTS OVERNIGHT. WITH SEAS 6-8 FT
OFFSHORE AND HIGHER IN THE GULF STREAM EXPECT SCA TO CONTINUE FOR
SEAS INTO THU NIGHT.

FRI-SUN...HIGH PRESSURE RIDGING REMAINS SITUATED NORTH AND WILL
GRADUALLY SHIFT OFF THE GA/SC/NORTH FL COASTS LATE IN THE PERIOD
WITH AN ONSHORE COMPONENT OF WIND DEVELOPING AND LASTING THROUGH THE
WEEKEND. A WEAKER PRESSURE GRADIENT IS EXPECTED TO BE IN PLACE WITH
WINDS AROUND 10 KTS OFFSHORE AND SUBSIDING SEAS FOR IMPROVING SMALL
CRAFT BOATING CONDITIONS THROUGH THE WEEKEND.

&&

.FIRE WEATHER...
TODAY...RED FLAG WARNING IS IN EFFECT FOR ALL OF EC FL FOR 6 TO 8
HOURS OF CRITICAL RH WITH SUSTAINED 20 FT WINDS GREATER THAN 15
MPH...GUSTS TO 25 MPH. MIN RH VALUES IN THE TEENS POSSIBLE OSCEOLA

DIVE INTO THE 20S FOR SEVERAL HOURS AGAIN DURING THE AFTERNOON WITH
SOME READINGS IN THE TEENS ACROSS PORTIONS OF INLAND
VOLUSIA...SEMINOLE...LAKE AND POSSIBLY NORTHWEST ORANGE COUNTIES.

FRI-SUN...HIGH PRESSURE OVER SOUTHERN GA/NORTHERN FL EARLY FRI
MORNING WILL DRIFT OFFSHORE INTO THE WESTERN ATLC PROVIDING ONSHORE
FLOW THRU THIS PERIOD. HAVE ISSUED A FIRE WEATHER WATCH FOR FRI
ACROSS INLAND VOLUSIA...LAKE...SEMINOLE...ORANGE AND NORTHWEST
OSCEOLA CTY. WHILE COASTAL AREAS ARE LIKELY TO MODERATE QUICKER WITH
RISING DEWPOINTS/RELATIVE HUMIDITIES...THESE AFOREMENTIONED INLAND
AREAS COULD STILL SEE 3-5 HRS OF RHS FROM 25%-35%. SAT-SUN...RH
VALUES ARE EXPECTED INCREASE AREAWIDE THUS LESSENING THE CHANCES FOR
LONG DURATION LOW RH DUE TO CONTINUED ONSHORE FLOW.
