AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MELBOURNE FL
921 AM EDT SUN APR 15 2007
.UPDATE DISCUSSION...
MORNING CAPE AND TBW SOUNDINGS SHOW STRONG WIND FIELDS IN THE LOW
LEVELS AND SUFFICIENT LOW LEVEL SHEAR TO BE CONCERNED ABOUT ISOLATED
TORNADOES. BUT LIMITED INSTABILITY EXISTS WITH H5 TEMPS -5/-6C.
TRACKING THE SQUALL LINE AS IT MOVES ONSHORE THE FL GULF COAST AND
SWEEPS EAST ACROSS CENTRAL FL NEXT 6 HOURS. APPEARS THAT THE LINE IS
BREAKING UP A BIT PRODUCING MORE DISCRETE CELLS WHICH MAY ENHANCE
THE TORNADO THREAT IN THE NEAR TERM FOR LAKE/VOLUSIA/SEMINOLE AND
ORANGE COUNTIES.
WITH THE LINE A BIT SLOWER THAN EXPECTED...SOUTHERN COUNTIES WILL
SEE SOME HEATING TODAY WITH MAX TEMPS REACHING THE LOW 80S AND
POSSIBLY MID 80S GIVEN THE ALREADY WARM MORNING TEMPS. INDICATIONS
ARE TORNADO THREAT WILL DECREASE SOMEWHAT AS THE LINE PUSHES INTO
SOUTHERN SECTIONS AFTER NOON BUT POTENTIAL FOR STRONGER WIND GUSTS
AND MORE FREQUENT LIGHTNING AND HEAVIER RAIN WILL EXIST.
BEHIND THE LINE...W/NW WINDS ARE EXPECTED TO INCREASE TO 20-25 MPH
WITH GUSTS 30-35 MPH. HENCE THE WIND ADVISORY. SKIES WILL CLEAR FROM
NW-SE DURING THE AFTN/EVE.
&&
.MARINE...STRONG ADVISORY CONDITIONS OCCURRING AND EXPECT WEST WINDS
TO INCREASE BEHIND THE SQUALL LINE WITH GUSTS TO GALE FORCE...SO NO
CHANGES TO THE CURRENT FORECAST ARE PLANNED.
&&
.PREVIOUS DISCUSSION...
...PRE-FRONTAL SQUALL LINE PASSAGE THIS MORNING/EARLY AFTN ACROSS
THE AREA...
...NEAR GALE CONDITIONS EXPECTED OVER THE ATLANTIC TODAY THROUGH
TONIGHT...
...INCREASING FIRE WEATHER CONCERN BEGINNING LATE TONIGHT INTO EARLY
NEXT WEEK...
CURRENT/TODAY...915 MHZ PROFILER WINDS AT CAPE SHOWING STRONG
SOUTHERLY LOW LEVEL FLOW AT 30-40 KTS EARLY THIS MORNING JUST OFF
THE DECK. FURTHER UPSTREAM WATER VAPOR/INFRARED SATELLITE IMAGERY
BOTH SHOWING A SQUALL LINE BEGINNING TO TAKE SHAPE FROM TALLAHASSEE
SOUTHWEST INTO THE GOMEX. SPOTTY CONVECTION IS BEGINNING TO DEVELOP
ACROSS WEST CENTRAL FLORIDA AND ACROSS COASTAL GULF WATERS OFF OF
THE NATURE COAST. THIS CAN BE EXPECTED TO CONTINUE THROUGH THE EARLY
MORNING HOURS UNTIL AN ORGANIZED SQUALL LINE EXPANDS SOUTHWARD
THROUGH THE GULF AND MOVES EASTWARD ACROSS THE PENINSULA. AS WITH
CONVECTION THIS PAST EVENING...BACKED SOUTHERLY FLOW IN THE LOW
LEVELS WILL ALLOW ANY NUMBER OF CELLS TO EXHIBIT ROTATION WITH
MODERATE/STRONG HELICITY VALUES CURRENTLY PRESENT. WHILE INSTABILITY
AND TEMPERATURES ALOFT REMAIN RATHER UNIMPRESSIVE ENOUGH DIRECTIONAL
SHEAR IN THE LOW LEVELS WILL BE PRESENT FOR ROTATING STORMS THROUGH
AT LEAST 15Z AND THIS TIMEFRAME FAVORS AREAS FROM ROUGHLY ORANGE
COUNTY NORTHWARD ACROSS EAST CENTRAL FLORIDA. A STRONG LINE OF
CONVECTION SHOULD BEGIN TO MOVE INTO LAKE/VOLUSIA COUNTIES SHORTLY
AFTER 10-12Z.
THE STRONG SOUTHERLY FLOW WILL BEGIN TO VEER BY MID MORNING AS THE
SURFACE LOW RACES NORTHWESTWARD ALONG THE EASTERN SEABOARD AND WITH
THE APPROACH OF A STRONG COLD FRONT. THE PRIMARY THREAT FROM
CONVECTION WILL BE ISOLATED DAMAGING WIND GUSTS...PERHAPS AN
ISOLATED TORNADO...DANGEROUS LIGHTNING AND HEAVY DOWNPOURS THROUGH
THIS MORNING. WILL CONTINUE TO KEEP POPS AT 80% WITH DECREASING
CHANCES OF CONVECTION FROM MID/LATE MORNING ON AND INTO THE EARLY
AFTERNOON FROM THE NORTH TO SOUTH ACROSS EAST CENTRAL FLORIDA. THE
COLD FRONT WILL MOVE RAPIDLY THROUGH THE AREA BEHIND THE SQUALL LINE
WITH SOUTH-SOUTHWEST WINDS VEERING TO THE WEST AND BECOMING
SUSTAINED AT 20 TO 25 MPH WITH SOME GUSTS AS HIGH AS 35 MPH...HENCE
THE WIND ADVISORY ACROSS THE ENTIRE CWA. HIGH TEMPERATURES SHOULD
AVERAGE IN THE 70S ACROSS MOST OF THE AREA...THOUGH COULD SEE A FEW
80 DEGREE READINGS ACROSS OUR SOUTHERN COUNTIES DEPENDING ON TIMING
OF PRECIPITATION AND FRONT.
TONIGHT...STRONG DRY/COLD AIR ADVECTION WILL SWEEP SOUTHWARD DOWN
THE PENINSULA. EXPECT GUSTY WEST/NORTHWEST WINDS TO CONTINUE THROUGH
THIS EVENING AS THE PRESSURE GRADIENT REMAINS TIGHT BEFORE SUBSIDING
SLIGHTLY AFTER MIDNIGHT...THOUGH MODELS CONTINUE TO SHOW BREEZY 15
TO 20 MPH WINDS CONTINUING OVERNIGHT. EXPECT MID/UPPER 40S FOR LOW
TEMPERATURES THOUGH IT WILL FEEL COLDER LATE TONIGHT WITH THE BRISK
NORTHWEST WINDS. A FEW 50 DEGREE READINGS WILL REMAIN POSSIBLE ALONG
THE COASTS OF ST. LUCIE AND MARTIN COUNTIES.
MONDAY...GFS PROGS DEEPENING LOW TO 974 MBS NEAR NYC 12Z MON MORNING
WITH DEEP LAYER DRY NW FLOW ACROSS E CENTRAL FL IN THE WAKE OF THE
DEPARTING STORM SYSTEM. SUNNY...WINDY AND COOL WITH HIGHS IN THE
LWR/MID 70S. EXPECT GUSTY CONDITIONS NEAR THE COAST IN THE MORNING
WITH SOME WIND GUSTS AS HIGH AS 25-30 MPH...BEFORE DIMINISHING SOME
BY LATE AFTERNOON.
MON NGT/TUE...STACKED LOW ACROSS THE NE U.S. WILL PULL EASTWARD INTO
THE ATLC WITH CONTINUED DRY NW FLOW. NW WINDS WILL STAY UP IN THE
10-15 MPH RANGE MOST AREAS WITH COOL LOWS NEAR 50 TO THE LOWER 50S.
ON TUE...ANOTHER DRY AND MOSTLY SUNNY AFTERNOON EXPECTED WITH
LIGHTER NW/W FLOW BY LATE AFTERNOON AS WEAK HIGH PRESSURE SETTLES IN
ACROSS THE ERN GULF. HIGHS SHOULD WARM BACK CLOSER TO CLIMO LEVELS
IN THE UPR 70S/LWR 80S.
WED...FAST MOVING SRN STREAM S/W PROGD TO AFFECT THE AREA WED
AFTERNOON AND WILL STICK CLOSE TO GUID AND KEEP RAIN CHANCES IN
30-40 PCT RANGE. LIMITED TIME FOR MOISTURE RECOVERY AHEAD OF NEXT
SYSTEM BUT IMPRESSIVE PROGD VORT LOBE ASSOC WITH S/W AND
STRENGTHENING MID LVL WINDS FIELDS SUGGEST POSSIBILITY FOR A FEW
STORMS IF MOISTURE RETURN IS ADEQUATE.
WED NGT-SUN...NW-N SFC FLOW THU WILL VEER TO NE-E THROUGH THE
WEEKEND AS A PROLONGED PERIOD OF MAINLY DRY WEATHER IS FORECAST. AN
AREA OF SFC HIGH PRES WILL BUILD TWD THE MID ATLC INTO THE WEEKEND
WITH NW FLOW ALOFT. TEMPS WILL AVERAGE SLIGHTLY BELOW CLIMO THROUGH
THE PERIOD WITH HIGHS IN THE UPR 70S/LWR 80S AND LOWS IN MID-UPR 50S
NRN INTERIOR TO LWR 60S FAR SRN CSTL SECTIONS.
&&
.AVIATION...LLWS WILL CONTINUE THROUGH ABOUT 13Z AS SOUTHERLY WINDS
JUST OFF THE SURFACE REMAIN STOUT AT UP TO 40 KTS. STRONG TO SVR
CONVECTION POSSIBLE THROUGH EARLY AFTN BEGINNING NORTH THIS MORNING
AND ENDING SOUTH EARLY THIS AFTN AS A SQUALL LINE IS FORECAST TO
MOVE ACROSS THE PENINSULA. BEHIND THE LINE OF CONVECTION A STRONG
COLD FRONT WILL MOVE ACROSS ECFL BRINGING WITH IT WINDY CONDITIONS
AS WEST WINDS INCREASE TO 20 KTS SUSTAINED WITH OCCASIONAL GUSTS TO
30 KTS POSSIBLE. IFR SQLN WITH EMBEDDED +TSRA PROGGED TO REACH THE
NRN AERODROMES OF DAB/SFB/LEE AROUND 11-13Z...MCO/ISM AROUND 14Z-16Z
AND MLB/VRB AROUND 16Z-18Z WITH POTENTIAL FOR MVFR SHRA TO LINGER A
COUPLE HRS AFTER THAT. WITH A CONTINUED STRONG PRESSURE GRADIENT
OVER THE AREA WINDS WILL BE SLOW TO DECREASE THIS EVENING/OVERNIGHT.
&&
.MARINE...SOUTHERLY WINDS IN EXCESS OF 20 KTS WITH HIGHER GUSTS WILL
BEGIN TO VEER TO THE SOUTHWEST AFTER 15Z AND EVENTUALLY WEST AFTER
20Z. A SCA CURRENTLY EXISTS OVER THE COASTAL WATERS BUT A GALE
WARNING WILL GO INTO EFFECT AT 14Z THROUGH THE REMAINDER OF THE
DAY/NIGHT AS STRONG OFFSHORE WINDS BEHIND A STRONG COLD FRONT WILL
BE FELT ACROSS THE REGION. EXPECT WINDS 20-25 KTS NEARSHORE/25-30
KTS OFFSHORE WITH FREQUENT GUSTS TO GALE FORCE. AHEAD OF THE FRONT
THIS MORNING...A LARGE SQUALL LINE IS FORECAST TO MOVE THROUGH THE
AREA WITH GUSTY WINDS...DANGEROUS LIGHTNING...HEAVY RAINFALL AND
EVEN AN ISOLATED WATERSPOUT ALL BEING IN PLAY. STRONG COLD AIR
ADVECTION WILL MOVE SOUTHWARD ACROSS THE COASTAL WATERS OVERNIGHT
WITH CONTINUED HAZARDOUS BOATING CONDITIONS. SEAS WILL CONTINUE TO
BUILD AWAY FROM THE IMMEDIATE COAST TODAY/TONIGHT WITH THE STRONG
OFFSHORE WINDS.
HAVE EXTENDED GALE FOR THE OFFSHORE WATERS INTO THE MONDAY MORNING
TIME FRAME WITH GALE FORCE GUSTS LIKELY OFFSHORE EARLY THEN WINDS
DROPPING BACK TO ADVISORY CONDS IN THE AFTERNOON. ALSO...EXTENDED
ADVISORY CONDITIONS FOR THE OFFSHORE INTO MONDAY NIGHT WITH NW WINDS
TO 20 KNOTS AND SEAS REMAINING ABOVE 7 FT WELL OFFSHORE. WINDS WILL
GRADUALLY DIMINISH TO 10-15 KT RANGE TUE AFTN-TUE NIGHT AS GRADIENT
RELAXES. NEXT FRONT MOVING THROUGH QUICKLY BY WED NIGHT WILL BRING A
ROUND OF 15-20 KNOT WINDS FOR THE OFFSHORE WATERS BUT GRADIENT
SHOULD BE LESS THAN BEHIND THE FRONT MOVING THROUGH LATER TODAY.
&&
.FIRE WEATHER...RH VALUES ACROSS THE NORTHERN CWA WILL REMAIN ABOVE
THRESHOLDS AS DRY AIR ADVECTION BUILDS STRONG INTO THE AREA LATE
TONIGHT. THE PRIMARY THREAT TODAY WILL BE STRONG WESTERLY WINDS
BEHIND A STRONG COLD FRONT...20-25 MPH WITH GUSTS TO 35 MPH. THE
PRESSURE GRADIENT REMAINS STRONG OVER THE AREA TONIGHT WITH WINDS
ONLY DECREASING SLIGHTLY. DISPERSION INDEX VALUES WILL BE QUITE HIGH
TODAY/TONIGHT AS A RESULT OF THE STRONG SURFACE/TRANSPORT LAYER
WINDS. WILL CONTINUE FIRE WEATHER WATCH ON MONDAY AFTERNOON WITH LOW
RH (25-30 PERCENT) AND NW WINDS 15 MPH+ ALL AREAS. WITH DAYTIME
MIXING...COULD SEE SOME GUSTS TO 25 MPH FROM MID MORNING INTO THE
EARLY AFTERNOON. TUE AFTERNOON LOOKS TO BE ANOTHER FIRE SENSITIVE
DAY WITH LOW RH FROM 30-35 PCT EXPECTED ACROSS INTERIOR SECTIONS.

LUCIE-MARTIN-COASTAL VOLUSIA- SOUTHERN LAKE-NORTHERN BREVARD- 459 AM EDT SUN APR 15 2007 THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA. .DAY ONE...TODAY AND TONIGHT. ...THUNDERSTORM IMPACT... A POWERFUL COLD FRONT WILL SWEEP DOWN THE FLORIDA PENINSULA TODAY...PRECEDED BY A LINE OF ORGANIZED THUNDERSTORMS. THIS LINE IS EXPECTED TO REACH LAKE AND VOLUSIA COUNTIES SHORTLY AFTER DAYBREAK AND CONTINUE SOUTH THROUGH EAST CENTRAL FLORIDA INTO THE EARLY AFTERNOON. VERY STRONG WINDS JUST ABOVE THE SURFACE WILL PRODUCE A HIGH THREAT FOR WIND GUSTS OF 40 TO 45 MPH...WITH THE POTENTIAL FOR DAMAGING WINDS AROUND 60 MPH AS THE SQUALL LINE RAPIDLY SWEEPS THROUGH THE AREA. WIND SHEAR PROFILES ALSO SUGGEST AN ISOLATED TORNADO IS POSSIBLE. ANY INDIVIDUAL STORMS THAT DEVELOP AHEAD OF THE MAIN SQUALL LINE WILL HAVE A HIGHER POTENTIAL TO BECOME TORNADIC. ALSO...ALTHOUGH THE PARENT SURFACE LOW WILL BE FAR TO THE NORTH...THERE IS POTENTIAL THAT A SMALLER SCALE LOW PRESSURE SYSTEM MAY MOVE OUT OF THE GULF OF MEXICO AND ACROSS THE CENTRAL PENINSULA. THIS WOULD LOCALLY ENHANCE THE TORNADO THREAT. THE GREATEST TORNADO THREAT APPEARS TO BE FROM ORANGE COUNTY NORTHWARD. BE AWARE THAT STRONG TO SEVERE STORMS WILL BE POSSIBLE THIS MORNING. BE SURE TO SET YOUR NOAA WEATHER RADIO TO ALERT. ...HIGH WIND IMPACT... A WIND ADVISORY IS IN EFFECT TODAY. SOUTHERLY WINDS WILL INCREASE...AND BECOME SOUTHWEST AND GUSTY ON EARLY THIS MORNING AHEAD OF A COLD FRONT...WHICH IS FORECAST TO SWEEP EASTWARD ACROSS THE AREA DURING THE DAY. WINDS ARE EXPECTED TO INCREASE FURTHER AS THEY SHIFT TO WEST AND NORTHWEST BY THE AFTERNOON. SUSTAINED WINDS NEAR 25 MPH WILL FREQUENTLY GUST WELL ABOVE 30 MPH...ESPECIALLY DURING THE AFTERNOON HOURS AS SKIES CLEAR BEHIND THE FRONT. A WIND ADVISORY MEANS THAT SUSTAINED WINDS OF 25 TO 39 MPH ARE EXPECTED. WINDS THIS STRONG WILL CAUSE LOOSE OBJECTS TO BLOW AROUND AND CAN MAKE DRIVING DIFFICULT...ESPECIALLY FOR HIGH PROFILE VEHICLES. ...MARINE THUNDERSTORM GUST IMPACT... STORMS THAT MOVE OFFSHORE WILL HAVE THE POTENTIAL TO PRODUCE WIND GUSTS OF 40 KNOTS OR GREATER. ...WATERSPOUT IMPACT... ANY STORMS THAT DEVELOP AND MOVE OFFSHORE WILL HAVE THE POTENTIAL TO PRODUCE TORNADIC WATERSPOUTS. ANY SUCH WATERSPOUTS WILL BE FAST MOVING AND WILL BE DIFFICULT TO SEE DUE TO HEAVY RAINFALL IN THE VICINITY. ...WIND AND SEA IMPACT... SOUTH TO SOUTHWEST WINDS WILL INCREASE 20 TO 25 KNOTS NEAR SHORE AND 25 TO 30 KNOTS OFFSHORE AS A STRONG FRONT APPROACHES. BEHIND THE FRONT WINDS WILL BECOME WEST LATE THIS MORNING AND EARLY THIS AFTERNOON ...EVENTUALLY SWITCHING TO NORTHWEST TONIGHT. GALE WARNINGS HAVE BEEN POSTED FOR TODAY AND TONIGHT AS FREQUENT GUSTS TO GALE FORCE ARE PROBABLE. ...FIRE WEATHER IMPACT... WHILE RELATIVE HUMIDITY VALUES ACROSS THE AREA WILL REMAIN ABOVE CRITICAL THRESHOLDS TODAY...STRONG WESTERLY WINDS BEHIND A COLD FRONT WILL INCREASE TO 20 TO 25 MPH WITH GUSTS TO 35 MPH. DISPERSION INDEX VALUES WILL BE QUITE HIGH TODAY DUE TO THE STRONG SURFACE AND TRANSPORT LAYER WINDS. SUCH HIGH WINDS WOULD PROMOTE A RAPID SPREAD TO ANY WILDFIRE...ESPECIALLY IF ANY FIRES WERE TO FROM LIGHTNING THIS MORNING. .DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY. A COOLER AND MUCH DRIER AIR MASS WILL MOVE INTO THE AREA BEHIND THE FRONT THROUGH EARLY NEXT WEEK. THE VERY DRY POST FRONTAL AIR MASS AND STRONG WINDS WILL ALSO BRING AN INCREASED FIRE WEATHER CONCERN TO THE AREA MONDAY AND TUESDAY. .SPOTTER INFORMATION STATEMENT... SPOTTERS SHOULD MONITOR THE WEATHER. FORMAL ACTIVATION MAY BE NEEDED. SEDLOCK
