AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL
333 AM EST THU JAN 6 2011

...CHANCE OF SHOWERS WITH EVEN A THUNDERSTORM ACROSS THE AREA
TODAY BEFORE COOLER AND DRIER WEATHER RETURNS FOR THE WEEKEND...

.DISCUSSION...
LOW PRESSURE WAS LOCATED JUST EAST OF JACKSONVILLE FLORIDA WITH A
COLD FRONT TRAILING SOUTHWEST THROUGH NORTH FLORIDA FROM THE LOW.
THE LOW WILL CONTINUE TO MOVE NORTHEAST AWAY FROM FLORIDA TODAY
ALLOWING FOR THE COLD FRONT TO MOVE SOUTHWARD DOWN THE SUNSHINE
STATE AND THROUGH SOUTH FLORIDA THIS EVENING. THIS WILL ALLOW FOR
THE WINDS TO BE SOUTHWEST OVER THE CWA TODAY WHICH IN TURN WILL
BRING IN LOW TO MID LEVEL MOISTURE TO THE AREA FROM THE GULF OF
MEXICO. SO HAVE INCREASE THE POPS A LITTLE BIT TODAY OVER THE CWA
TO 50 PERCENT OVER THE NORTHERN AREAS TO 40 PERCENT OVER THE
SOUTHERN AREAS.

A SHORT WAVE IN THE MID LEVELS OF THE ATMOSPHERE OVER THE WESTERN
GULF OF MEXICO EARLY THIS MORNING WILL MOVE EAST ACROSS THE GULF
OF MEXICO AND THROUGH SOUTH FLORIDA THIS AFTERNOON. THIS WILL HELP
TO GENERATE A FEW THUNDERSTORMS TODAY ACROSS THE CWA MAINLY DURING
LATE MORNING AND EARLY AFTERNOON HOURS. SPC HAS ALSO PUT SOUTH
FLORIDA IN A 5 PERCENT SEVERE THREAT TODAY MAINLY FOR SOME GUSTY
WINDS WITH ANY STORMS THAT DO DEVELOP...DUE TO A LOW TO MID LEVEL
JET AROUND 50 KNOTS COMING WITH THE SHORT WAVE. SO WILL MENTION
GUSTY WINDS WITH ANY STORMS THAT DO DEVELOP TODAY IN THE HWO
PACKAGE.

ONCE THE FRONT COMES THROUGH SOUTH FLORIDA THIS EVENING...COOLER
AND DRY WEATHER WILL WORK INTO SOUTH FLORIDA LATE TONIGHT INTO
FRIDAY AS HIGH PRESSURE BUILDS INTO THE SOUTHEAST UNITED STATES
FROM THE NORTHERN PLAIN STATES. LOWS TONIGHT WILL FALL INTO 50S
OVER THE METRO AREAS TO 40S OVER THE INTERIOR AREAS...EXCEPT UPPER
30S WEST OF LAKE OKEECHOBEE. HIGHS ON FRIDAY WILL BE AROUND 70
ACROSS THE CWA.

THE HIGH WILL THEN MOVE EAST INTO THE WESTERN ATLANTIC WATERS OVER
THE WEEKEND KEEPING THE WEATHER DRY AND THE TEMPERATURES COOL TO
COMFORTABLE OVER THE CWA. HIGHS WILL BE IN THE 70S THIS WEEKEND.
LOWS WILL BE IN THE 50S OVER THE METRO AREAS TO 40S OVER THE
INTERIOR AREAS...EXCEPT MID TO UPPER 30S OVER THE INTERIOR AREAS
WEST OF LAKE OKEECHOBEE.

.EXTENDED FORECAST...
THE LONG RANGE MODELS CONTINUE TO SHOW ANOTHER LOW DEVELOPING OVER
THE WESTERN GULF OF MEXICO LATE THIS WEEKEND MOVING EAST ACROSS
NORTH FLORIDA OR THE SOUTHEAST UNITED STATES EARLY NEXT WEEK. THE
COLD FRONT ASSOCIATED WITH THE LOW HAS SPEED UP A LITTLE BIT WITH
THE PASSAGE NOW LATE MONDAY NIGHT INSTEAD OF TUESDAY. THIS HAS
SHIFTED THE PRECIP OVER THE CWA FROM TUESDAY TO MONDAY AFTERNOON.
SO HAVE ADJUSTED THE TIMING OF THE POPS EARLY NEXT WEEK TO
REFLECT THE SPEED UP OF THE FRONT. THE POPS WILL STILL REMAIN
SLIGHT CHANCE...AS MOST OF THE ENERGY WILL BE NEAR THE LOW AND NOT
ALONG THE COLD FRONT.

THE LONG RANGED MODELS HAVE ALSO COOLED A LITTLE BIT WITH THE
TEMPERATURES BEHIND THE SECOND COLD FRONT FOR THE MIDDLE OF NEXT
WEEK OVER THE CWA...DUE THE STRONG HIGH BEING SHIFTED A LITTLE BIT
SOUTH INTO THE SOUTHEAST UNITED STATES INSTEAD OF OVER THE TENNESSEE
VALLEY. SO HAVE ADJUSTED THE TEMPERATURES DOWN A LITTLE BIT FOR
MIDDLE OF NEXT WEEK TO REFLECT THE COOL DOWN.

&&

.MARINE...
THE WINDS WILL BE SOUTHWEST TODAY AT 15 TO 20 KNOTS THIS MORNING
BEFORE INCREASING TO AROUND 20 KNOTS THIS AFTERNOON. THE WINDS
WILL THEN SHIFT TO A NORTHWEST DIRECTION TONIGHT OVER THE CWA
WATERS AND INCREASE TO 20 TO 25 KNOTS OVER MOST OF THE CWA WATERS
BEHIND THE PASSAGE OF THE COLD FRONT. THE WINDS WILL THEN REMAIN
NORTHWEST ON FRIDAY INTO SATURDAY WITH SPEEDS DECREASING TO 15 TO
20 KNOTS...BEFORE SWINGING TO A EASTERLY DIRECTION BY LATE SUNDAY.

THIS WILL ALLOW FOR THE SEAS IN THE GULF STREAM TO BUILD TO 7 TO
8 FEET BY LATE TONIGHT...AND REMAIN THERE THROUGH FRIDAY MORNING
BEFORE SLOWLY DECREASING TO LESS THAN 6 FEET BY SATURDAY MORNING.
THE GULF STREAM SEAS WILL THEN REMAIN BELOW 6 FEET THIS WEEKEND.

THE NEAR-SHORE ATLANTIC WATERS WILL ALSO BUILD TO 4 TO 6 FEET LATE
TONIGHT BEFORE SLOWLY DECREASING TO LESS THAN 6 FEET FRIDAY
AFTERNOON AND REMAIN BELOW 6 FEET THROUGH THE WEEKEND.

IN THE GULF WATERS...THE SEAS WILL BUILD TO 4 TO 6 FEET NEAR-SHORE
LATE TONIGHT BEFORE SLOWLY DECREASING TO LESS THAN 6 FEET BY
FRIDAY EVENING AND REMAIN BELOW 6 FEET THROUGH THE WEEKEND. IN THE
OFFSHORE GULF WATERS...THE SEAS WILL BUILD TO 7 FEET LATE TONIGHT
BEFORE DECREASING TO LESS THAN 6 FEET BY FRIDAY EVENING AND REMAIN
BELOW 6 FEET THROUGH THE WEEKEND.

&&

.FIRE WEATHER...
THE RELATIVE HUMIDITIES TODAY WILL REMAIN ABOVE THE 35 PERCENT
CRITICAL VALUE DUE TO THE MOISTURE OVER THE THE CWA. ON
FRIDAY...THE RELATIVE HUMIDITIES SHOULD FALL INTO THE MID TO UPPER
30S AS THE DRY AIR WORKS INTO THE CWA. SO AT THIS TIME WILL NOT
ISSUED A FIRE WEATHER WATCH FOR THE CWA FOR FRIDAY BUT WILL
CONTINUE TO MONITOR THE LATEST MODEL RUNS ON THE RELATIVE
HUMIDITIES. FOR THE WEEKEND...THE RELATIVE HUMIDITIES WILL ALSO
REMAIN ABOVE THE 35 PERCENT CRITICAL VALUE.

THE KBDI INDEX FOR SOUTH FLORIDA IS CURRENTLY AT 600 TO 650 FOR
GLADES AND PALM BEACH COUNTIES...550 TO 600 FOR HENDRY...COLLIER...AND
BROWARD COUNTIES...500 TO 550 FOR MIAMI- DADE COUNTY...AND 450 TO
500 FOR MAINLAND MONROE COUNTY. THIS MEANS THAT THE FIRE DANGER IS
STILL HIGH TO VERY HIGH OVER THE CWA.

&&

.HYDROLOGY...
AT THIS TIME THE SHORT RANGE MODELS ARE SHOWING THAT THE RAINFALL
AMOUNTS TODAY WILL BE BETWEEN TENTH TO QUARTER OF AN INCH EXPECT
AROUND 1 INCH WITH ANY STORMS THAT DO DEVELOP OVER THE CWA. THESE
RAINFALL AMOUNTS WILL ONLY TEMPORARY HELP WITH THE DROUGHT STATUS THAT
IS CURRENTLY IN A SEVERE DROUGHT OVER THE NORTHERN AREAS TO A
MODERATE DROUGHT OVER THE SOUTHERN AREAS OF THE CWA.
