AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL
1036 PM EST TUE JAN 25 2011
.UPDATE...
AT 0330Z OR 1030 PM EST THE SQUALL LINE EXTENDS FROM NORTHERN
MAINLAND MONROE TO CENTRAL PALM BEACH COUNTY. A COOL POOL HAS
MOVED THE LEADING EDGE OF THE LINE AHEAD OF THE MAIN DYNAMICS.
THIS IS REDUCING THE TORNADO THREAT. STRAIGHT LINE WIND DAMAGE
IS THE MOST LIKELY THREAT. AS THE LINE IS APPROACHING
THE HIGHEST DEWPOINTS OF THE AREA IT IS TRYING TO FORM SMALL LOW
TOPPED CELLS AHEAD OF IT AS IT ENTERS NORTHWEST MIAMI-DADE
COUNTY. BETWEEN 1115 PM EST AND 1130 PM EST THE LINE OF STORMS IS
EXPECTED TO APPROACH DOWNTOWN MIAMI. STRONG CONVECTION OVER THE
ATLANTIC COASTAL WATERS IS EXPECTED AS THE LINE OF STORMS ENTERS
THE COASTAL WATERS AND TRIES TO CREATE MULTIPLE CELLS AHEAD OF THE
LEADING EDGE OF THE COOL POOL OVER THE WATER.
BETWEEN MIDNIGHT AND SUNRISE EXPECT WIDESPREAD SHOWERS WITH A FEW
RUMBLES OF THUNDER POSSIBLE.
THE TORNADO WATCH IS STILL IN EFFECT UNTIL MIDNIGHT.

NEAR TERM...
A TORNADO WATCH HAS BEEN ISSUED FOR GLADES...HENDRY...PALM BEACH
COLLIER...AND BROWARD COUNTIES UNTIL MIDNIGHT...
THE FORECAST REASONING CONTINUES UNCHANGED SINCE EARLIER THIS
AFTERNOON. AN AREA OF MOISTURE CONVERGENCE WEST OF COLLIER COUNTY
COULD LEAD TO THE FORMATION OF SOME DISCRETE ISOLATED
THUNDERSTORMS WITH THE POTENTIAL OF BECOMING SEVERE. ANOTHER AREA
OF MOISTURE CONVERGENCE IS LOCATED OVER THE SOUTHERN TIP OF THE
PENINSULA. THE MAIN ENERGY TO FUEL TORNADIC SUPERCELLS IS FORECAST
TO MOVE NORTHEAST AS THE LINE OF STORMS CONTINUES TO PUSH
SOUTHEASTWARD. ACCORDING TO THE SPC MESOSCALE ANALYSIS THE 0-6 KM
SHEAR IS LESS THAN 50 KNOTS SOUTH OF PALM BEACH AND HENDRY
COUNTIES WITH A TONGUE OF 50 KNOT SHEAR EXTENDING INTO THE GULF OF
MEXICO SOUTHWEST OF COLLIER COUNTY. THE SURFACE TO 1KM SHEAR
INCREASES AS WE MOVE NORTHWARD. AT 730 PM EST THE STRONGEST
LIGHTNING ACTIVITY IS LOCATED OVER THE GULF OF MEXICO NORTHWEST OF
COLLIER COUNTY. IF AN ISOLATED TORNADO WERE TO OCCUR THIS EVENING
IT WILL MOST LIKELY OCCUR JUST AHEAD OF THE MAIN SQUALL LINE. NORTHERN
COLLIER...HENDRY...AND NORTH PALM BEACH COUNTIES INCLUDING LAKE
OKEECHOBEE WILL BE THE FIRST LOCATIONS TO RECEIVE THE IMPACT OF
THE SQUALL LINE WITHIN THE NEXT 45 MINUTES TO AN HOUR AND A HALF.
OTHER NEAR TERM AND SHORT TERM DISCUSSIONS WILL BE ISSUED THIS
EVENING WITH FURTHER DETAILS AS CONDITIONS WORSEN WITH THE
APPROACH OF THE SQUALL LINE.
PREV DISCUSSION... /ISSUED 651 PM EST TUE JAN 25 2011/
AVIATION...SQUALL LINE CURRENTLY MOVING ONTO THE WEST CENTRAL
COAST OF THE PENINSULA WILL SHIFT E THROUGH TONIGHT MOVING THROUGH
THE KAPF AND KPBI TERMINALS AROUND 3-5Z AS ITS ORIENTED NE-SW. THE
QUESTION IS HOW MUCH IT WILL MAINTAIN ITSELF TO REACH THE SE
TERMINALS. HAVE INDICATED THE GREATEST THREAT AFT 09Z WITH PROB30
GROUPS. CONVECTION WILL END EARLY WEDNESDAY MORNING AROUND 12Z BUT
LOW CIGS WILL BE SLOW TO IMPROVE WITH VFR BEGINNING WEDNESDAY
AFTERNOON. SFC WIND WILL SLOWLY BECOME SW AT ALL TERMINALS TONIGHT
AND THEN BECOME WNW AFT FRONTAL PASSAGE.
KOB
PREV DISCUSSION... /ISSUED 219 PM EST TUE JAN 25 2011/
STRONG TO SEVERE THUNDERSTORMS POSSIBLE THIS EVENING AND
OVERNIGHT...
DISCUSSION...SHORT TERM FOCUS CONTINUES TO BE ON THE POTENTIAL
FOR STRONG TO SEVERE THUNDERSTORMS THIS EVENING AND OVERNIGHT. A
ROBUST SHORTWAVE WILL QUICKLY MOVE EAST OVER THE GULF OF MEXICO
THROUGH THIS EVENING AS SURFACE LOW PRESSURE MOVES OVER NORTH
FLORIDA. ANOTHER LOW PRESSURE SYSTEM WILL ALSO ORGANIZE OFF THE
SOUTHEAST COAST. THE AIR MASS OVER SOUTH FLORIDA HAS MOISTENED
CONSIDERABLY OVER THE PAST 24 HOURS...WITH DEWPOINTS CURRENTLY
RANGING THROUGH THE MID AND UPPER 60S. MEANWHILE...H85 WINDS ARE
INCREASING...AND WILL APPROACH 45 KNOTS BY LATE AFTERNOON OFF THE
SOUTHWEST FLORIDA COAST. THE LATEST RADAR AND SATELLITE IMAGERY
SHOW THAT NUMEROUS THUNDERSTORMS HAVE ALREADY FORMED IN THE
NORTHERN GULF OF MEXICO...WITH A DISTINCT AND ORGANIZED LINE OF
CONVECTION EXTENDING WELL TO THE SOUTHWEST. AS THE SOUTHERN
BRANCH OF THE SHORTWAVE TROUGH SWINGS EASTWARD...THE ASSOCIATED
SURFACE LOW WILL DEEPEN. SINCE THIS PRIMARY LOW PRESSURE AREA
WILL BE WELL TO OUR NORTH...THE MID AND UPPER LEVEL DYNAMICS WILL
AT LEAST INITIALLY BE LACKING. HOWEVER...WARM SURFACE
TEMPERATURES AND A GRADUAL CAP EROSION COMBINED WITH 0-3KM AGL
MOST UNSTABLE CAPE IN EXCESS OF 1000 J/KG, 0-6KM SHEAR INCREASING
TO NEAR 50 KNOTS AND HELICITY VALUES IN EXCESS OF 200 M^2/S^2, A
FEW DISTINCT SUPERCELLS MAY FORM THIS EVENING - WITH THE HIGHEST
RISK OVER GLADES, HENDRY, AND COLLIER COUNTIES. IF THIS SCENARIO
WERE TO UNFOLD, AN ISOLATED TORNADO WOULD BE POSSIBLE. LATE THIS
EVENING AND OVERNIGHT, THE MOST ORGANIZED AREA OF SHOWERS AND
EMBEDDED THUNDERSTORMS WILL GRADUALLY MOVE INTO THE REGION -
FIRST IMPACTING WESTERN LOCALES BY 06Z...AND THEN TRANSITIONING
TO EASTERN AREAS BY 10Z. AT THIS TIME, THE MOST PLAUSIBLE
CONVECTIVE MODE LATE THIS EVENING AND OVERNIGHT WILL BE A LINEAR
SQUALL LINE WITH DAMAGING WINDS BEING THE PRIMARY THREAT.
CONDITIONS WILL SLOWLY IMPROVE AFTER SUNRISE WEDNESDAY...ALTHOUGH
THE ORGANIZED LINE OF SHOWERS AND THUNDERSTORMS MAY LINGER ALONG
THE EAST COAST UNTIL ABOUT 14Z. BY MIDDAY, THE MID LEVEL TROUGH
WILL PASS THROUGH THE REGION WITH UPPER LEVEL FLOW GRADUALLY
BECOMING MORE ZONAL IN ITS WAKE.
HIGH PRESSURE WILL THEN BUILD THURSDAY THROUGH SUNDAY...WITH
CONTINUED DRY WEATHER. WEAK COLD AIR ADVECTION AND LOW LEVEL
NORTHERLY FLOW MAY RESULT IN LOW TEMPERATURES DIPPING INTO THE
30S WEST OF THE LAKE ON THURSDAY AND FRIDAY MORNING...WITH A
GRADUAL MODERATION IN TEMPERATURES EXPECTED SATURDAY AFTERNOON
THROUGH SUNDAY. A VERY WEAK COLD FRONT WILL PASS TO OUR NORTH
MONDAY INTO MONDAY NIGHT. AS HIGH PRESSURE AGAIN BUILDS BEHIND IT,
LOW LEVEL FLOW WILL TURN SOUTHEASTERLY WITH CONTINUED WARMING
TEMPS, ESPECIALLY ALONG THE EAST COAST.
AVIATION...BKN/OVC DECK BETWEEN 020-025 SHOULD PERSIST OVER ALL
BUT THE IMMEDIATE KAPF AREA THROUGH THE REST OF THE AFTERNOON AS
MARINE LAYER WILL BE STUBBORN TO MOVE AWAY FROM AREA. WILL START
TO SEE A FEW BREAKS IN THE LOWEST BASES LATER THIS AFTERNOON AND
THIS EVENING WITH BKN040 ABOVE. MAIN CLOUD/PRECIP AREA MOVING
THROUGH AREA FROM W TO E BETWEEN 06Z-15Z. WENT WITH MVFR
CONDITIONS WITH CHC OF TSRA OVERNIGHT, WITH BRIEF IFR PERIODS
LIKELY BUT NOT ENOUGH TO WARRANT MENTION IN TAFS. SOME STORMS
COULD BE STRONG OVERNIGHT WITH GUSTS ABOVE 40-45 KT IN STRONGEST
STORMS.
MARINE...A TIGHT PRESSURE GRADIENT WILL RESULT IN ADVISORY WIND
SPEEDS THROUGH TONIGHT...AND CONTINUING OVER THE ATLANTIC WATERS
THROUGH WEDNESDAY AFTERNOON. SOME THUNDERSTORMS THIS EVENING AND
OVERNIGHT MAY ALSO PRODUCE WIND GUSTS IN EXCESS OF 35 KNOTS. ONCE
A COLD FRONT PASSES EARLY WEDNESDAY, WINDS AND SEAS WILL REMAIN
ELEVATED BEFORE GRADUALLY SUBSIDING WEDNESDAY EVENING INTO
THURSDAY AS HIGH PRESSURE BUILDS INTO THE REGION.
FIRE WEATHER...NO SHORT TERM CONCERNS AS RELATIVE HUMIDITIES WILL
REMAIN ABOVE 35 PERCENT THROUGH EARLY THURSDAY. MINIMUM RH MAY
DROP BELOW 35 PERCENT ACROSS SOME AREAS THURSDAY, FRIDAY, AND
SATURDAY AFTERNOONS.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR SOUTH FLORIDA. .DAY ONE...TONIGHT RIP CURRENTS: STRONG SOUTHEAST WINDS OF 15 TO 20 MPH WITH HIGHER GUSTS WILL RESULT IN A HIGH RISK OF DANGEROUS RIP CURRENTS ALONG THE ATLANTIC BEACHES OF PALM BEACH, BROWARD AND MIAMI-DADE COUNTIES THROUGH THIS AFTERNOON. THUNDERSTORMS: A BAND OF STRONG TO LOCALLY SEVERE THUNDERSTORMS IS EXPECTED TO MOVE ACROSS SOUTH FLORIDA FROM WEST TO EAST TONIGHT. THE ACTIVITY WILL LIKELY MOVE ONSHORE THE SOUTHWEST GULF COAST AROUND MIDNIGHT AND MOVE THROUGH THE SOUTHERN PENINSULA DURING THE OVERNIGHT HOURS, EXITING THE SOUTHEAST COAST SHORTLY BEFORE DAYBREAK. TORNADOES: THERE IS A VERY SLIGHT RISK OF TORNADOES AND WATERSPOUTS IN ASSOCIATION WITH THE MAIN BAND OF STORMS OVERNIGHT. A HIGHER RISK OF TORNADOES IS POSSIBLE OVER THE WESTERN HALF OF SOUTH FLORIDA THIS EVENING, ESPECIALLY IF ISOLATED STORMS DEVELOP AHEAD OF THE MAIN RAIN AREA MOVING EAST FROM THE GULF OF MEXICO. WIND: WIND GUSTS OF 50 MPH OR GREATER ARE POSSIBLE WITH THE STRONGER STORMS THIS EVENING AND OVERNIGHT AS THE PRIMARY RAIN AREA MOVES EAST ACROSS THE PENINSULA. WAVES: SEAS TO 7 FEET ARE POSSIBLE OVER THE ATLANTIC WATERS TODAY. .DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY THUNDERSTORMS WILL LIKELY BE ONGOING OVER THE EAST COAST METRO AREA EARLY WEDNESDAY MORNING, BEFORE MOVING OFFSHORE BY MID TO LATE MORNING AHEAD OF THE COLD FRONT. ANOTHER ROUND OF SEASONABLY COOL WEATHER IS EXPECTED BEHIND THE FRONT FOR LATE IN THE WEEK, WITH LOWS AGAIN DROPPING INTO THE 40S ACROSS MUCH OF THE AREA BY FRIDAY AND INTO THE UPCOMING WEEKEND. LOWS WILL DROP INTO THE MID TO UPPER 30S DEGREE ACROSS THE LAKE OKEECHOBEE REGION. .SPOTTER INFORMATION STATEMENT... SPOTTER ACTIVATION MAY BE NEEDED FROM LATE THIS AFTERNOON THROUGH THE OVERNIGHT HOURS AS THUNDERSTORMS DEVELOP AHEAD OF THE APPROACHING FRONT.
