AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL
256 PM EST THU DEC 14 2006

.DISCUSSION...
AREAS OF RAIN AND EMBEDDED THUNDERSTORMS CONTINUE TO AFFECT
PRIMARILY THE EASTERN HALF OF THE SOUTH FLORIDA THIS AFTERNOON...
WITH RECORD-BREAKING RAIN TOTALS REPORTED IN PALM BEACH COUNTY.
THIS ACTIVITY HAS BEEN FOCUSED BY WHAT APPEARS TO BE A WEAK
INVERTED SURFACE TROUGH LOCATED NEAR THE I-95 CORRIDOR. AFTER
INITIAL DEVELOPMENT THIS MORNING...ADDITIONAL CONNECTIVE DEVELOPMENT
OCCURRED AS THE LOW-LEVEL JET FED RICH TROPICAL MOISTURE INTO THE
SYSTEM. MODERATELY STRONG SOUTHERLY FLOW IN THE LOWEST 10 KFT OF
THE TROPOSPHERE HAS ALLOWED FOR ECHO TRAINING...WITH WIDESPREAD
REPORTS OF FLOODING ACROSS BROWARD AND PALM BEACH COUNTIES. AS
WARM ADVECTION CONTINUES TO DRAW VERY MOIST AIR NORTHWARD
OVERNIGHT...EXPECT RAIN TO CONTINUE ACROSS VIRTUALLY THE ENTIRE
FORECAST AREA...AND WILL CARRY CATEGORICAL POPS FOR THURSDAY NIGHT
AND FRIDAY...IN LINE WITH FWC/MAV/MET NUMBERS. ALTHOUGH FLOODING WILL BE
THE GREATEST CONCERN FOR THE REMAINDER OF THIS EVENT...STEEPENING MID-
LEVEL LAPSE RATES AND SIGNIFICANT LOW-LEVEL HODOGRAPH CURVATURE
WILL MAINTAIN A THREAT FOR EMBEDDED THUNDERSTORMS. ALTHOUGH VERY
DIFFICULT TO DETERMINE AT THIS TIME...THE HEAVY RAINFALL THREAT
MAY BE GREATEST NEAR INVERTED SURFACE TROUGH ACROSS EASTERN HALF
OF THE PENINSULA.

SHORT TERM GUIDANCE CONTINUE TO SHOW BETTER TEMPORAL AND SPATIAL
CONTINUITY REGARDING THE EVOLUTION OF A WEAK SOUTHERN STREAM UPPER
LOW ACROSS SOUTHERN TEXAS/NORTHERN MEXICO. THIS FEATURE IS PROGGED
TO WEAKEN AS IT MOVES EASTWARD ACROSS THE GULF OF MEXICO...WITH
RAIN CHANCES ENDING FROM NORTHWEST TO SOUTHEAST LATE ON SATURDAY...
AS UPPER LOW MOVES EAST OF THE AREA AND WEAK FRONTAL PASSAGE
ALLOWS SLIGHTLY COOLER AND DRIER AIR TO FILTER IN FROM THE NORTH.
MODERATE NORTHEASTERLY FLOW REGIME WILL REMAIN IN PLACE THROUGH
THE BEGINNING OF NEXT WEEK...WITH A VERY LOW CHANCE FOR LIGHT
STREAMER SHOWERS TO AFFECT THE EASTERN BEACH AREAS AND ATLANTIC
WATERS. OTHERWISE...MEDIUM RANGE SOLUTIONS FORM THE ECMWF/GFSLR
SEEM TO BE IN GENERAL AGREEMENT ON A RETROGRESSION OF THE UPPER
LOW TOWARD THE FIRST PART OF NEXT WEEK...BUT DIFFER WITH RESPECT
TO WHERE THE LOWEST HEIGHTS WILL EVENTUALLY RESIDE. THE GFSLR
SOLUTION WOULD OFFER ANOTHER GOOD CHANCE OF RAIN FOR FLORIDA BY
MIDLATE WEEK IF IT WERE TO VERIFY. HOWEVER...THE ECMWF SOLUTION
ALSO SEEMS REASONABLE...AND WILL ONLY INCLUDE VERY LOW CHANCES FOR
PRECIPITATION TO REFLECT DEGREE OF UNCERTAINTY.

&&

.AVIATION...
NUMEROUS SHOWERS AND THUNDERSTORMS ARE EXPECTED TO CONTINUE ACROSS
SOUTH FLORIDA INTO FRIDAY EVENING OCCASIONALLY REDUCING VISIBILITY
TO AROUND 1 MILE, AND ALSO OCCASIONALLY REDUCING THE CEILINGS TO
AROUND 300 FEET AS A TROUGH OF LOW PRESSURE ACCOMPANIED WITH DEEP
TROPICAL MOISTURE RIDES ACROSS THE AREA. WINDS WILL ALSO BE
PROBLEMATIC DURING THE PERIOD. WINDS MAY GUST UP TO 30 KNOTS AS A
THUNDERSTORM PASSES.

&&

.MARINE...
ISOLATED STRONG CONVECTION WILL CONTINUE TO CREATE HAZARDOUS
BOATING CONDITIONS THROUGH THE FIRST HALF OF THE WEEKEND.
HOWEVER...EXPECT THE MOST SIGNIFICANT INCREASE IN WAVE HEIGHTS TO
OCCUR AFTER PERSISTENT NORTHERLY FLOW FOLLOWING SATURDAYS FRONTAL
PASSAGE. WAVE HEIGHTS MAY INCREASE TO 6 FEET ACROSS THE GULF
STREAM TOWARD THE END OF THE WEEKEND.

&&

.FIRE WEATHER...
NO CONCERNS THROUGHOUT THIS FORECAST PERIOD...WITH MINIMUM RELATIVE
HUMIDITY VALUES EXPECTED TO REMAIN HIGH THROUGH THE PERIOD.
