358 AM EDT MON APR 17 2006

CORRECTED MAXIMUM TEMPERATURE RANGE

...RED FLAG WARNING IN EFFECT FROM 1 PM THIS AFTERNOON TO 7 PM
EDT THIS EVENING...

HIGH PRESSURE RIDGE HAS MOVED A LITTLE FURTHER SOUTH AND WILL PRODUCE
A BIT STRONGER WESTERLY FLOW THAN ON SUNDAY. THIS WILL PREVENT THE
SEA BREEZE FROM PENETRATING INLAND AND WILL BE PINNED ALONG THE
COAST OVER PALM BEACH AND BROWARD COUNTIES THIS AFTERNOON. THEREFORE,
MAXIMUM TEMPERATURES IN THE UPPER 80S COMBINED WITH DEW POINTS IN 
THE UPPER 50S WILL PRODUCE RELATIVE HUMIDITIES AT OR JUST BELOW 35 
PERCENT FOR 4 HOURS OR MORE THIS AFTERNOON THROUGH 7 PM THIS EVENING.

A RED FLAG WARNING MEANS THAT CRITICAL FIRE WEATHER CONDITIONS
ARE EITHER OCCURRING NOW...OR WILL SHORTLY. A COMBINATION OF
STRONG WINDS... LOW RELATIVE HUMIDITY...AND WARM TEMPERATURES WILL
CREATE EXPLOSIVE FIRE GROWTH POTENTIAL.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL
154 AM EDT MON APR 17 2006

.DISCUSSION...SURFACE RIDGE EXTENDS FROM THE CENTRAL BAHAMAS THROUGH SOUTH
FLORIDA...RESULTING IN LIGHT SOUTHWEST FLOW OVER THE AREA. THIS IS
ALSO RESULTING IN ABOVE AVERAGE TEMPERATURES ALONG THE ATLANTIC
COAST WITH HIGHS AGAIN EXPECTED TO REACH THE UPPER 80S IN PLACES
OVER THE NEXT COUPLE OF DAYS. THE WEST COAST WILL SEE HIGHS IN THE
LOWER 80S...AROUND SEASONAL NORMS. THE ATMOSPHERE REMAIN DRY AND
FAIRLY STABLE WITH A PERSISTENT CAP AROUND 5KFT. THUS NOT EXPECTING
ANY RAIN CHANCE THROUGH TUESDAY. FOR THE TEMPERATURE FORECAST...WARM
GUIDANCE TEMPS ON EAST COAST LOOK OKAY...MAY GO A DEGREE ABOVE IN
PLACES. MAV IS TOO WARM ON THE WEST COAST HOWEVER GIVEN ONSHORE
FLOW. FAVOR SLIGHTLY COOLER MET VALUES.

MEANWHILE...THE COMBINATION OF A REX BLOCK OVER THE GREAT LAKES AND
A STRONG SHORT WAVE TROUGH OVER THE OHIO VALLEY WILL HELP DIG A
TROUGH OVER THE WESTERN ATLANTIC OVER THE NEXT COUPLE OF DAYS...PUSHING
A BACKDOOR FRONT INTO LOCAL ATLANTIC WATERS BY WEDNESDAY. THIS WILL
BRING SLIGHTLY MORE MOISTURE AND MODERATE THE WARM TEMPS ON THE EAST
COAST SOMEWHAT...BUT WONT BE ENOUGH TO PRODUCE ANY MUCH NEEDED
RAINFALL. JUST A FEW SPITS ON THE ATLANTIC COAST IF ANYTHING AT ALL.

FOR LATER IN THE WEEK AND NEXT WEEKEND...A WEAK PRESSURE PATTERN
WILL BE IN PLACE WITH DIURNAL SEA BREEZE MECHANISMS THE MAIN
PLAYERS. RIDGE WILL AGAIN MIGRATE OVER THE AREA...DRYING AND WARMING
THURSDAY AND FRIDAY...WITH MODEST RECOVERY BY THE WEEKEND AS THE
RIDGE SHIFTS INTO THE ATLANTIC AND DELIVERS ONSHORE FLOW. IN
SHORT...RAIN CHANCES STILL DONT LOOK TOO GOOD ATTM.

&&

.MARINE...LIGHT TO MODERATE SOUTHWEST TO WEST FLOW WILL VEER MORE
NORTHERLY AND SUBSIDE ON WEDNESDAY AS WEAK FRONT PUSHES INTO
ATLANTIC WATERS. LIGHT FLOW TO PERSIST THROUGH FRIDAY AS HIGH
PRESSURE BUILDS OVER THE AREA. LIGHT TO MODERATE EAST TO SOUTHEAST
FLOW BY SATURDAY AS HIGH PRESSURE BUILDS OVER ATLANTIC.

&&

.FIRE WEATHER...ANOTHER TRICKY FORECAST SETTING UP. GULF MOISTURE WILL
LIKELY KEEP AFTERNOON RELATIVE HUMIDITY THE WESTERN AREAS ABOVE
THRESHOLD. THE EAST COAST COUNTIES ARE MORE OF A QUESTION. THERE
ARE A COUPLE OF INDICATIONS THAT PALM BEACH...BROWARD...AND
MIAMI-DADE MAY DIP BELOW THRESHOLD. FIRST...IT COULD BE A LITTLE
WARMER TODAY THAN YESTERDAY. SECOND...THE SOUTHWEST GRADIENT FLOW
WILL BE A LITTLE STRONGER AS WELL...HOLDING OFF A EAST COAST SEA
BREEZE THAT WOULD COOL TEMPS A LITTLE AND BRING UP DEW POINTS IN THE
AFTERNOON. THE WESTERLY FLOW MAY BRING GULF MOISTURE HOWEVER AND DEW
POINTS MAY NOT DIP QUITE LOW ENOUGH LONG ENOUGH. THIS IS ESPECIALLY
TRUE IN MIAMI-DADE SITTING CLOSER TO THE WEST COAST AND FLORIDA BAY
THAN BROWARD OR PALM BEACH. ALSO THE GRADIENT FLOW IS LIGHTER
MIAMI-DADE AND THE EAST COAST SEA BREEZE HAS MORE OF A CHANCE OF
DEVELOPING AND PENETRATING INLAND. GOING TO GAMBLE THAT THE SEA
BREEZE WILL BE HELD TO THE IMMEDIATE ATLANTIC COAST IN PALM BEACH
AND BROWARD...AND WARM TEMPS WILL ALLOW RHS TO MEET THESHOLDS. WILL
LEAVE MIAMI-DADE OUT...EXPECTING THAT DURATION REQUIREMENTS WILL NOT
BE MET.
