Damaging Winds in Florida, April 22, 2012

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL
153 AM EDT SUN APR 22 2012

.AVIATION...

ALTHOUGH EAST COAST TERMINALS HAVE NO SHOWERS IN VICINITY...GIVEN
THAT SHOWERS OR AN ISOLATED THUNDERSTORM COULD DEVELOP AT MOST ANY
TIME DECIDED TO ASSIGN VCSH THROUGH THE EARLY MORNING HOURS. FOR
TERMINAL KAPF...THERE IS A LINE OF HEAVY SHOWERS AND EMBEDDED
THUNDERSTORMS ACROSS THE GULF WATERS TO THE WEST OF THE TERMINAL.
SO VCTS ASSIGNED WITH A TEMPO GROUP FOR THUNDERSTORMS THROUGH
09Z. ALTHOUGH NOT INDICATED IN TEMPO GROUP...BRIEF PERIODS OF IFR
CONDITIONS POSSIBLE AS THE LINE OF SHOWERS AND THUNDERSTORM
RAPIDLY PASSES EASTWARD. THE LATEST GUIDANCE AND REGIONAL
OBSERVATIONS INDICATE A SURGE OF STRONG WESTERLY WINDS BUILDING
INTO THE REGION EARLY THIS MORNING INTO SUNDAY AFTERNOON.
OBSERVATIONS ACROSS THE EASTERN GULF AND THE KEYS INDICATE THAT
THE WESTERLIES ARE ALREADY BUILDING INTO THE REGION. AS THE
AFOREMENTIONED LINE OF SHOWERS/THUNDERSTORMS ENTERS THE WESTERN
PENINSULA...WILL HAVE TO WAIT AND SEE IMPACTS FOR EAST COAST
TERMINALS. WILL AMEND AS NECESSARY.

..TORNADO WATCH 186 IN EFFECT UNTIL 7 AM EDT SUNDAY FOR SOUTH
FLORIDA...

UPDATE...
EVENING PRODUCTS HAVE BEEN UPDATED FOR THE INCLUSION OF THE TORNADO
WATCH HEADLINE THROUGH 7 AM SUNDAY MORNING. STORMS HAVE BEGUN TO
DEVELOP OVER THE EASTERN GULF AND ALONG THE TAMPA COAST AS THE
POTENT UPPER LOW APPROACHES THE FLORIDA PENINSULA. ALTHOUGH THE
BEST THUNDERSTORM COVERAGE...BASED ON THE LATEST RADAR LOOP...WAS
STILL NORTH AND NORTHWEST OF OUR LOCAL AREA OFF OF TAMPA'S
COAST...SCATTERED TO NUMEROUS STORMS ARE EXPECTED TO BEGIN
DEVELOPING OFF OF THE NAPLES COAST OVER THE NEXT FEW HOURS. THESE
STORMS WILL BE FAST MOVING STORMS TRACKING NORTHEAST AND WILL BE
CAPABLE OF PRODUCING DAMAGING WINDS UP TO AROUND 60-70 MPH...LARGE
HAIL AND TORNADOES.

PREV DISCUSSION... /ISSUED 821 PM EDT SAT APR 21 2012/

.STRONG TO SEVERE STORMS STILL POSSIBLE TONIGHT INTO SUNDAY MORNING...

UPDATE...
A SHORT WAVE AHEAD OF THE MID TO UPPER LEVEL LOW IN THE GULF OF
MEXICO HAS MOVED EAST OF THE FLORIDA PENINSULA LATE THIS
AFTERNOON. THIS HAS ALLOWED FOR THE DRIER AIR IN THE MID TO UPPER
LEVELS TO WORK INTO THE CWA FROM THE GULF OF MEXICO WHICH IN TURN
ALLOWED FOR THE DEEP TROPICAL MOISTURE TO GET PUSH EAST INTO THE
ATLANTIC WATERS. AT THE SAME TIME...THE TRANSPORT WINDS HAVE ALSO
INCREASED FROM THE SOUTHWEST WHICH IN TURN WILL ALLOW FOR ANY
STORMS THAT DO DEVELOP TONIGHT TO MOVE QUICKLY OVER THE AREA AND
REDUCED THE RAINFALL AMOUNTS FROM THE STORMS. THEREFORE...THE
FLOOD WATCH FOR ALL OF SOUTH FLORIDA HAS BEEN CANCELLED.

THE UPPER LEVEL LOW OVER THE CENTRAL GULF OF MEXICO WILL ALSO
CONTINUE TO MOVE EAST AND THROUGH THE FLORIDA PENINSULA OVERNIGHT
TONIGHT INTO SUNDAY...BEFORE MOVING INTO THE WESTERN ATLANTIC
WATERS ON SUNDAY AFTERNOON. THIS WILL CONTINUE TO BRING IN COLDER
AND DRIER AIR TO THE MID TO UPPER LEVELS OVER THE CWA TONIGHT
WHICH IN TURN WILL ALLOW FOR MORE SHOWER AND THUNDERSTORMS TO
DEVELOP OVER THE AREA LATER TONIGHT INTO SUNDAY MORNING.

SOME OF THE STORMS COULD STILL BE STRONG TO SEVERE TONIGHT INTO
SUNDAY MORNING OVER THE CWA...DUE TO A LOW TO MID LEVEL JET OF 30
TO 40 KNOTS MOVING INTO THE AREA FROM THE GULF OF MEXICO ALONG
WITH A UPPER LEVEL JET OF 100 TO 110 KNOTS. THE MID TO UPPER
LEVELS WILL ALSO BE VERY COLD WITH TEMPERATURES IN THE -11C TO
-15C.

THERE COULD ALSO STILL BE A TORNADO OR TWO OVER ALL OF SOUTH
FLORIDA TONIGHT...AS 00Z SOUNDING FROM MIA IS SHOWING TURNING IN
THE LOWEST LEVELS OF THE ATMOSPHERE.

THE WINDS WILL ALSO INCREASE TO WINDY CONDITIONS AFTER MIDNIGHT
TONIGHT OVER THE METRO AREAS WITH BREEZY OVER REST OF THE CWA...DUE
TO THE PRESSURE GRADIENT TIGHTEN BETWEEN THE LOW PRESSURE SYSTEM
AND THE HIGH OVER THE CENTRAL UNITED STATES. THE PRESSURE GRADIENT
WILL CONTINUE TO TIGHTEN OVER THE CWA ON SUNDAY WITH WINDS OF 25
TO 30 MPH WITH GUSTS UP TO NEAR 35 MPH OVER THE METRO AREAS TO 20
TO 25 MPH OVER REST OF THE CWA. IF THESE FORECAST WINDS CONTINUE
FOR SUNDAY...THEN A WIND ADVISORY WILL MORE LIKELY BE NEEDED FOR
THE METRO AREAS OF SOUTH FLORIDA ON SUNDAY.

THE WIND GUSTS OVER THE CWA WATERS ON SUNDAY COULD EVEN GET UP
INTO THE GALE FORCE CONDITIONS. SO WE WILL ALSO MONITOR THE WIND
GUSTS FOR THE POSSIBLE GALE WARNING CONDITIONS FOR THE CWA FOR
SUNDAY.

UPDATE...54/BNB

PREV DISCUSSION... /ISSUED 750 PM EDT SAT APR 21 2012/

AVIATION...
ONLY ISOLATED SHOWERS REMAIN ACROSS SOUTH FLORIDA AS OF THIS TAF
ISSUANCE. THIS IS A RESULT OF MID LEVEL DRYING THAT IS PUSHING
EAST ACROSS THE EASTERN GULF OF MEXICO AHEAD OF THE STRONG H5 LOW.
CURRENTLY THERE IS UNCERTAINTY WITH THE COVERAGE AND INTENSITY OF
THE SHRAS/TSRAS THAT WILL ACCOMPANY THIS LOW AS IT PROGRESSES TO
THE EAST. WITH REGARD TO TAF SITES...DECIDED TO KEEP A VICINITY
MENTION FOR SHOWERS ATTM. WINDS WILL BEGIN TO TURN MORE WESTERLY
AND INCREASE OVERNIGHT AS THE ASSOCIATED SURFACE LOW PASSES BY TO
THE NORTH.

PREV DISCUSSION... /ISSUED 324 PM EDT SAT APR 21 2012/

SHORT TERM...
CLOUD COVER AND EARLIER RAINFALL HAS KEPT THE REGION VERY STABLE
THROUGHOUT THE DAY. ONLY LIGHT/MODERATE STRATIFORM RAIN HAS
FALLEN DURING MOST OF THE DAY. ACTUALLY LOW MAXIMUM TEMPERATURES
MAY BE SET ACROSS MUCH OF THE REGION AS TEMPERATURES HAVE ONLY
RISEN INTO THE LOW TO MID 70S. THE WARM FRONT HAS NOT MADE MUCH
NORTHWARD PROGRESS EITHER. THE CONVECTION NEAR THE KEYS ALSO STOLE
THE ENERGY FROM THE SQUALL LINE...AND IT IS FALLING APART AS IT IS
MOVING EAST. SOME SHOWERS AND THUNDERSTORMS MAY MAKE IT INTO
COLLIER COUNTY FROM THE FIRST SQUALL LINE...BUT MOST GUIDANCE
SHOWS THIS FALLING APART AS IT MOVES INTO A MORE STABLE
ENVIRONMENT.

THERE ARE SOME BREAKS IN THE CLOUDS WEST OF THE GULF COAST AND IF
THERE IS ANY HEATING SHOWERS AND THUNDERSTORMS MAY DEVELOP IN
THIS REGION OF DIFFERENTIAL HEATING. THE LOCAL WRF-NMM AND HRRR
BOTH CONTINUE TO SHOW THE POSSIBILITY OF DEVELOPMENT NORTHWEST OF
KEYS THIS AFTERNOON...AND THIS AREA OF STORMS MOVING INTO MAINLAND
MONROE AND MIAMI DADE COUNTY LATE THIS AFTERNOON INTO THE EARLY
EVENING. THERE WAS SOME DEVELOPMENT WEST OF THE KEYS THIS
AFTERNOON...AND THIS MAY BE WHAT THE MODELS WERE KEYING ON. THE
WARM FRONT IS ALSO EXPECTED TO MOVE NORTHWARD...AND IF THIS
OCCURS...MORE SHOWERS AND THUNDERSTORMS WILL BE POSSIBLE ACROSS
THE REGION. WAS TEMPTED TO DROP THE FLOOD WATCH ACROSS THE
AREA...BUT WILL KEEP IT FOR NOW BECAUSE THERE IS STILL THE
POTENTIAL FOR HEAVY RAIN LATE THIS AFTERNOON AND TONIGHT.

THE UPPER LEVEL LOW ACROSS THE CENTRAL GULF APPEARS TO HAVE
STOPPED ITS SOUTHWARD MOVEMENT AND WAS MOVING TO THE EAST
NORTHEAST. THIS WOULD PUT THE UPPER LOW A LITTLE FURTHER NORTH
THAN PREVIOUS GUIDANCE HAD INDICATED...WHICH MAY PUT THE SECOND
SQUALL LINE MAINLY TO THE NORTH OF THE REGION LATE TONIGHT...WITH
THE TAIL END MOVING ACROSS SOUTH FLORIDA. THIS IS WHAT IS
DEPICTED BY THE LOCAL WRF-NMM AND THE LATEST GFS. SINCE THE UPPER
LOW IS EXPECTED TO BE A LITTLE FURTHER NORTH...THE UPPER LEVEL JET
STREAK IS EXPECTED TO BE LOCATED ACROSS SOUTH FLORIDA
TONIGHT INSTEAD OF THE FLORIDA STRAITS. THIS WOULD PUT MAINLY THE
LAKE REGION AND NORTHWARD IN THE LEFT FRONT QUADRANT OF THE 120KT
UPPER LEVEL JET. SO THE BEST CHANCE OF SEVERE WEATHER TONIGHT MAY
BE ACROSS THE LAKE REGION AS THE UPPER VORT MOVES ACROSS CENTRAL
FLORIDA TONIGHT. HOWEVER...WITH EXCELLENT UPPER DIVERGENCE...500MB
TEMPS OF -11 TO -13C...AND LOW LEVEL JET OF 35-40 KNOTS...SEVERE
WEATHER WILL BE POSSIBLE ACROSS THE ENTIRE REGION STARTING AROUND
MIDNIGHT THROUGH ABOUT 10Z. THE MAIN THREATS WILL HEAVY
RAIN...STRAIGHT LINE WINDS IN EXCESS OF 60 MPH AND HAIL.

THE STRONGEST ACTIVITY SHOULD CLEAR THE COAST AROUND 12Z OR
SHORTLY THEREAFTER. MOISTURE MAY WRAP AROUND THE LOW PRESSURE AND
SHOWERS WILL BE POSSIBLE THROUGH THE DAY. WITH THE CLOUD COVER
EXPECTED ON SUNDAY...HIGHS ARE EXPECTED TO ONLY REACH AROUND 80 TO
THE LOWER 80S. THE LEFTOVER MOISTURE IS EXPECTED TO CLEAR THE
REGION AFTER 00Z MONDAY...WITH COOLER AND MUCH DRIER AIR MOVING
INTO THE REGION. LOW PRESSURE IS EXPECTED TO DEEPEN AS IT MOVES UP
THE EAST COAST PUSHING MUCH COOLER AIR INTO THE SOUTHEAST STATES.
UNDER THE NORTHWESTERLY FLOW....COOLER TEMPERATURES ARE EXPECTED
FOR MONDAY MORNING WITH LOWS IN THE 50S TO LOWER 60S.

LONG TERM...
DRY AND COOLER TEMPERATURES WILL CONTINUE ON MONDAY WITH NORTHWEST
FLOW CONTINUING. HIGHS ARE EXPECTED TO ONLY REACH THE UPPER 70S TO
LOWER 80S. THE UPPER LEVEL LOW ACROSS THE NORTHEAST WILL CONTINUE
TO DEEPEN AND THE UPPER LEVEL TROUGH WILL CONTINUE TO DIG INTO THE
SOUTHEAST. MUCH COOLER AIR IS EXPECTED TO CONTINUE FILTERING SOUTH
INTO THE SOUTHEAST STATES AND FLORIDA. BY 12Z TUESDAY...850MB
TEMPS ARE EXPECTED TO BE AROUND 4C NEAR THE LAKE AND 6-7C ACROSS
DEEP SOUTH FLORIDA. THE EKDMOS BIAS CORRECTED IS INDICATING THE
POSSIBILITY OF TEMPERATURES IN THE LOW/MID 40S ACROSS THE INTERIOR
FOR TUESDAY MORNING. HOWEVER...MOST OTHER GUIDANCE IS INDICATING
UPPER 40S/LOWER 50S AND AROUND 60 FOR THE EAST COAST METRO AREAS.
WITH THE LOWER THICKNESS VALUES EXPECTED...WENT CLOSER TO THE
EKDMOS AND HAVE TEMPERATURES IN THE MID/UPPER 40S INTERIOR AND THE
MID/UPPER 50S FOR THE EAST COAST METRO AREAS. DRY WEATHER AND
COOL TEMPERATURES WILL CONTINUE THROUGH THE MIDDLE TO END OF THE
WEEK.

AVIATION...18Z ISSUANCE...
WIDESPREAD AREA OF RAIN WITH SOME EMBEDDED THUNDERSTORMS,
CONTINUES TO MOVE SLOWLY NORTHEAST FROM THE FLORIDA KEYS. THIS
ACTIVITY MAY DIMINISH IN INTENSITY AS IT PUSHES NORTH. ANOTHER
AREA OF SHOWERS AND THUNDERSTORMS, MAINLY IN THE FORM OF A SQUALL
LINE, EXTENDS FROM THE BIG BEND SOUTH TO WEST OF THE COLLIER
COUNTY COAST. VCTS IS WARRANTED AT THE TAF SITES THROUGH AT LEAST
06Z AS ANOTHER SECONDARY LINE OF CONVECTION MAY IMPACT THE REGION
JUST AHEAD OF A COLD FRONT. BRIEF MVFR-IFR CEILINGS AND
VISIBILITIES ARE POSSIBLE IN ANY SHRA OR TSRA. VCSH IS THEN
CARRIED FOR THE PERIOD 06Z-14Z WITH IMPROVING CONDITIONS
THEREAFTER. SURFACE WINDS WILL REMAIN SSW WITH HIGHER GUSTS
LIKELY, ESPECIALLY WEST COAST. WINDS WILL THEN BECOME WSW AFTER
14Z WITH FREQUENT GUSTS OF 20 TO 25 KNOTS AT ALL SITES.

MARINE...
SMALL CRAFT ADVISORIES ARE IN EFFECT FOR ALL LOCAL WATERS THROUGH
AT LEAST EARLY MONDAY MORNING. A STRONG COLD FRONT WILL MOVE
ACROSS THE REGION ON SUNDAY AND WINDS WILL INCREASE TO 20 TO 25
KNOTS OVER THE ATLANTIC AND GULF WATERS. SEAS ARE EXPECTED TO
BUILD TO 7 TO 10 FEET OVER THE GULF AND AROUND 7 FEET OVER THE
GULF STREAM.

FIRE WEATHER...
NO FIRE WEATHER CONCERNS THROUGH SUNDAY. A STRONG COLD FRONT WILL
MOVE THROUGH THE REGION SUNDAY AFTERNOON...AND MUCH COOLER AND
DRIER AIR WILL FILTER INTO THE REGION ON MONDAY. RELATIVE HUMIDITY
VALUES MAY DROP TO 30-35 PERCENT ACROSS MUCH OF THE REGION.
