DISCUSSION...
HIGH PRESSURE OVER THE GULF OF MEXICO WILL MOVE ACROSS THE FLORIDA
PENINSULA TONIGHT ALLOWING FOR CLEAR SKY AND LIGHT WINDS OVER THE

TONIGHT. LOW TEMPERATURES ARE EXPECTED TO FALL INTO THE UPPER 30S
TO LOWER 40S OVER THE INTERIOR AREAS TO THE MID 40S TO LOWER 50S
OVER THE METRO AREAS TONIGHT.

THE ONLY EXCEPTION IS OVER THE GLADES...HENDRY...AND INLAND
COLLIER COUNTIES WHERE THE LOW TEMPS WILL FALL INTO THE MID TO
UPPER 30S TONIGHT. SO WILL ADD PATCHY FROST OVER GLADES...HENDRY...AND
INLAND COLLIER COUNTIES FOR LATE TONIGHT INTO EARLY WEDNESDAY
MORNING. IF THE TEMPERATURES FALL FASTER THAN FORECASTED THIS
EVENING...THEN THE EVENING SHIFT MAY HAVE TO LOWER THE LOW TEMPS A
LITTLE BIT MORE FOR TONIGHT...AND POSSIBLY ADDING AREAS OF FROST.

THE HIGH WILL THEN MOVE SLOWLY EAST INTO THE ATLANTIC WATERS
WEDNESDAY INTO THURSDAY AS LOW PRESSURE DEVELOPS OVER TEXAS. THE
LOW WILL THEN CONTINUE TO MOVE EAST INTO THE SOUTHEAST UNITED
STATES BY LATE THIS WEEK. THIS WILL ALLOW FOR THE WINDS OVER THE
CWA TO SWING FROM A NORTHERLY DIRECTION ON WEDNESDAY TO A
SOUTHERLY DIRECTION BY LATE THIS WEEK...AND ALLOW FOR LOW LEVEL
MOISTURE TO WORK INTO THE AREA FROM THE ATLANTIC WATERS. SO WILL
CONTINUE TO KEEP THE WEATHER DRY WEDNESDAY AND THURSDAY OVER SOUTH
FLORIDA...BEFORE INTRODUCING A SLIGHT CHANCE OF SHOWERS BY
FRIDAY.

EXTENDED FORECAST...
THE LOW PRESSURE SYSTEM WILL CONTINUE TO MOVE EAST INTO THE
WESTERN ATLANTIC WATERS THIS WEEKEND FROM THE SOUTHEAST UNITED
STATES DRAGGING A COLD FRONT THROUGH SOUTH FLORIDA SATURDAY
EVENING. AHEAD OF THE FRONT...THE WINDS WILL BE SOUTHWEST OVER THE
CWA ALLOWING FOR DEEPER TROPICAL MOISTURE TO WORK INTO THE CWA
FROM THE GULF OF MEXICO. SO WILL CONTINUE THE CHANCE OF SHOWERS
AND SLIGHT CHANCE OF THUNDERSTORMS OVER THE CWA ON SATURDAY.
ANOTHER HIGH PRESSURE SYSTEM WILL THEN WORK INTO THE AREA FROM THE
NORTH FOR LATE THIS WEEKEND INTO EARLY NEXT WEEK ALLOWING FOR DRY
AND COOLER WEATHER OVER SOUTH FLORIDA.

MARINE...
THE WINDS WILL BE FROM THE NORTH AT 10 TO 15 KNOTS TONIGHT INTO
WEDNESDAY...BEFORE SWINGING TO A SOUTHEAST DIRECTION LATE THIS
WEEK. THIS WILL ALLOW THE SEAS TO BE UP TO 4 FEET IN THE ATLANTIC
AND GULF WATERS TONIGHT THROUGH FRIDAY. SO NO HEADLINES IN THE
MARINE PACKAGE TONIGHT THROUGH FRIDAY.

FIRE WEATHER...
THE RELATIVE HUMIDITIES THIS AFTERNOON HAVE BEEN RUNNING FROM THE
UPPER TEENS TO MID 20S ACROSS THE CWA. THE RELATIVE HUMIDITIES
SHOULD GET ABOVE 35 PERCENT BY 00Z ACROSS THE CWA THIS
EVENING...AS THE TEMPERATURES COOL AND THE DEW POINTS RAISE FROM
THE MID 20S INTO THE 30S. SO WILL CONTINUE THE RED FLAG WARNING
FOR ALL OF SOUTH FLORIDA UNTIL 7 PM EST THIS EVENING.

THE DRY WEATHER WILL CONTINUE OVER SOUTH FLORIDA ON WEDNESDAY OVER
SOUTH FLORIDA. HIGHS WILL BE IN THE LOWER TO MID 70S WITH DEW
POINTS IN THE 30S TO AROUND 40. THIS WILL ALLOW FOR THE RELATIVE
HUMIDITIES TO FALL BELOW 35 PERCENT FOR 4 HOURS OR MORE OVER MOST
OF THE CWA WEDNESDAY AFTERNOON.

HOWEVER...THE WINDS SHOULD SHIFT TO A NORTHEAST DIRECTION ALONG
THE EAST COAST METRO AREAS IN THE AFTERNOON WHICH SHOULD HELP TO
KEEP THE DEW POINTS UP A LITTLE BIT IN THE LOWER TO MID 40S. THIS
IN TURN SHOULD KEEP THE RELATIVE HUMIDITIES OVER THE EAST COAST
METRO AREAS IN THE UPPER 30S TO LOWER 40S WEDNESDAY AFTERNOON. SO
AT THIS TIME...WILL ISSUED A FIRE WEATHER WATCH FOR ALL OF THE
INTERIOR AND WEST COAST METRO AREAS FOR WEDNESDAY AFTERNOON FOR 4
HOURS OR MORE OF BEING BELOW 35 PERCENT IN THE RELATIVE HUMIDITIES.
