..SEVERE THUNDERSTORM WATCH 8 IN EFFECT UNTIL 11 PM EDT FOR MOST OF
SOUTH FLORIDA EXCEPT FOR MIAMI-DADE AND MAINLAND MONROE COUNTIES...
SHORT TERM...
LOW PRESSURE LOCATED OVER THE BIG BEND REGION OF FLORIDA WILL
CONTINUE TO MOVE NORTHEAST ACROSS NORTH FLORIDA LATE THIS AFTERNOON
AND INTO THE NORTHWEST ATLANTIC WATERS TONIGHT. THIS WILL ALLOW A
SQUALL LINE OVER THE EASTERN GULF OF MEXICO TO MOVE EAST AND
THROUGH SOUTH FLORIDA THIS EVENING. THE SQUALL LINE SHOULD BE EAST
OF SOUTH FLORIDA BY LATE TONIGHT OR EARLY THURSDAY MORNING.
SOME OF THE THUNDERSTORMS IN THE SQUALL LINE COULD BECOME STRONG TO
SEVERE...AS THERE IS A LOW TO MID LEVEL JET OF 30 TO 50 KNOTS
ACCOMPANYING THE SQUALL LINE. THE PRIMARY IMPACTS FROM THE STRONG TO
SEVERE STORMS WILL MAINLY BE GUSTY WINDS...HAIL...FREQUENT
LIGHTNING...AND HEAVY RAINFALL. SPC HAS ALSO ISSUED A SEVERE
THUNDERSTORM WATCH FOR MOST OF SOUTH FLORIDA UNTIL 11 PM EST. SO
WILL CONTINUE TO MENTION STRONG TO SEVERE STORMS IN THE FORECAST FOR
THIS EVENING OVER SOUTH FLORIDA. THE POPS WILL ALSO BE RAISED TO
CATEGORICAL FOR THIS EVENING...BEFORE SLOWLY TAPERING IT DOWN
THROUGH THE OVERNIGHT HOURS.
THE COLD FRONT ASSOCIATED WITH THE LOW PRESSURE SYSTEM WILL ALSO
MOVE SOUTHEAST AND THROUGH SOUTH FLORIDA ON THURSDAY. THIS FRONT
WILL BRING IN MUCH COOLER AND DRIER WEATHER TO THE AREA FOR
THURSDAY NIGHT INTO FRIDAY. SO WILL CONTINUE A SLIGHT CHANCE TO
LOW END CHANCE OF SHOWERS OVER SOUTH FLORIDA FOR THURSDAY...BEFORE
GOING DRY FOR THURSDAY NIGHT INTO FRIDAY.
THE WINDS WILL ALSO BE ON AN INCREASE LATE TONIGHT AND SHOULD BE
AT LEAST 25 TO 30 MPH OVER THE METRO AREAS ON THURSDAY WITH AROUND
20 MPH OVER THE INTERIOR AREAS. THE WIND GUSTS COULD EVEN GET UP
TO AROUND 30 MPH ALONG THE METRO AREAS OF SOUTH FLORIDA. IF THIS
TREND CONTINUES THEN A WIND ADVISORY WILL BE NEEDED LATE TONIGHT
FOR THURSDAY OVER SOUTH FLORIDA.
THE MODELS HAVE TRENDED A LITTLE BIT LOWER FOR THE LOW
TEMPERATURES OVER SOUTH FLORIDA FOR THURSDAY NIGHT. AT THIS
TIME...LOW TEMPERATURES FOR THURSDAY NIGHT WILL BE IN THE MID TO
UPPER 40S OVER MOST OF SOUTH FLORIDA...EXCEPT UPPER 30S WEST OF
LAKE OKEECHOBEE AND UPPER 40S TO LOWER 50S SOUTHEAST PORTIONS OF
SOUTH FLORIDA.
THE WIND SPEEDS WILL ALSO BE DECREASING THURSDAY EVENING...AND
SHOULD BE LESS THAN 5 MPH BY LATE THURSDAY NIGHT INTO EARLY FRIDAY
MORNING...AS HIGH PRESSURE BUILDS INTO THE AREA FROM THE NORTH.
SO THERE SHOULD BE NO WIND CHILL PROBLEMS OVER SOUTH FLORIDA FOR
THIS TIME FRAME.
THE HIGH WILL THEN MOVE EAST INTO THE WESTERN ATLANTIC WATERS ON
FRIDAY ALLOWING FOR ANOTHER COLD FRONT TO MOVE THROUGH SOUTH
FLORIDA ON FRIDAY NIGHT. HOWEVER...THIS FRONT WILL BE A DRY FRONT
WHICH WILL REINFORCE THE DRY WEATHER OVER SOUTH FLORIDA THIS WEEKEND.
LONG TERM...
THE DRY WEATHER WILL REMAIN IN PLACE OVER SOUTH FLORIDA EARLY TO
MIDDLE OF NEXT WEEK...AS HIGH PRESSURE WILL BUILD BACK INTO SOUTH
FLORIDA FROM THE NORTH. SO WILL CONTINUE THE DRY WEATHER OVER THE
AREA FOR THE EARLY TO MIDDLE PART OF NEXT WEEK.
MARINE...
THE WINDS WILL BE ON AN INCREASE THIS EVENING...AND BY LATE THIS
EVENING INTO LATE TONIGHT THE WIND SPEEDS WILL BE AT 20 TO 25
KNOTS OVER ALL OF THE SOUTH FLORIDA WATERS FROM THE SOUTHWEST TO
WEST DIRECTION. THE WIND SPEEDS WILL THEN REMAIN AT 20 TO 25 KNOTS
ON THURSDAY WHILE SWINGING FROM A WEST TO A NORTHWEST DIRECTION
WITH THE PASSAGE OF THE COLD FRONT. THE WIND SPEEDS WILL THEN
SLOWLY DECREASE THURSDAY NIGHT AND BY FRIDAY BE AT 15 KNOTS OR
LESS.
THE ATLANTIC SEAS WILL BE BUILDING TO 7 TO 9 FEET LATE TONIGHT
INTO THURSDAY BEFORE SLOWLY SUBSIDING TO LESS THAN 7 FEET LATE
THURSDAY NIGHT. THE GULF SEAS WILL ALSO BE BUILDING TO 8 TO 10
FEET LATE TONIGHT INTO THURSDAY...BEFORE SLOWLY SUBSIDING TO LESS
THAN 7 FEET BY LATE THURSDAY NIGHT.
FIRE WEATHER...
THE RELATIVE HUMIDITY WILL REMAIN ABOVE 35 PERCENT ON THURSDAY
OVER SOUTH FLORIDA. HOWEVER...THE RELATIVE HUMIDITY ON FRIDAY
ACROSS SOUTH FLORIDA SHOULD FALL INTO THE LOWER TO MID 30S FOR
COUPLE OF HOURS IN THE AFTERNOON. HOWEVER...THE 20 FOOT WINDS WILL
BE BELOW 15 MPH AND THE ENERGY RELEASE COMPONENT WILL ALSO BE
BELOW 35. THEREFORE...NO CONCERNS ARE EXPECTED AT THIS TIME WITH
THE FIRE WEATHER OVER SOUTH FLORIDA ON FRIDAY.
