AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL
344 AM EST SAT MAR 6 2010

.DISCUSSION...
SOME UPPER LEVEL MOISTURE AND OCCASIONAL PATCHES OF CIRRUS STREAM
ACROSS THE SOUTH FLORIDA PENINSULA...HELPING TO MODERATE THE
TEMPERATURES A LITTLE EARLY THIS MORNING. BUT THERE ARE BREAKS IN
THE CLOUDINESS AND REGIONAL OBSERVATIONS INDICATE TEMPERATURES
AROUND PALMDALE ARE CURRENTLY AROUND 40 OR UPPER 30S WHILE THE
WEST AND EAST COAST METRO AREAS ARE SO FAR REMAINING IN THE MID TO
UPPER 40S. WILL LEAVE A CHANCE OF EARLY MORNING PATCHY FROST IN
THE NORTHWEST INTERIOR WEST OF LAKE OKEECHOBEE IN THE CURRENT
FORECAST.

DRY AND STABLE CONDITIONS CONTINUE ACROSS THE REGION WITH A NORTH
TO NORTHWEST FLOW ACROSS THE PENINSULA AND REGIONAL WATERS.
SURFACE HIGH PRESSURE IS WELL ESTABLISHED ACROSS THE GREAT LAKES
AND EXTENDS SOUTHWARD ACROSS THE EASTERN PORTION OF THE COUNTRY
INCLUDING THE FLORIDA PENINSULA AND REGIONAL WATERS. A MID TO
UPPER LEVEL RIDGE WILL CONTINUE ACROSS THE SOUTHEAST U.S. AND
FLORIDA PENINSULA THROUGH AT LEAST MONDAY KEEPING SOUTH FLORIDA
UNDER VERY STABLE AND DRY CONDITIONS. BY TUESDAY AN UPPER LEVEL
LOW AND DEVELOPING COLD FRONT IS FORECAST TO DEVELOP IN THE MID
WEST...WITH A MORE SOUTHERLY SURFACE FLOW DEVELOPING ACROSS THE
REGION. SOUTHWESTERLY LOW LEVEL FLOW IS FORECAST TO BRING CLOUDINESS
AND MOISTURE ACROSS THE REGION...WITH LATEST GUIDANCE SUGGESTING
THAT CHANCES OF PRECIP ARE MINIMAL. BY MID WEEK FURTHER
DEVELOPMENT OF THE SYSTEM IN THE MID WEST IS EXPECTED AND WILL
CONTINUE TO BRING SOUTHERLY FLOW AND ADDITIONAL MOISTURE ACROSS
THE REGION WITH ISOLATED SHOWERS POSSIBLE. THE EXTENDED GUIDANCE
INDICATES YET ANOTHER FRONT FORECAST TO PASS ACROSS THE REGION BY
THURSDAY. WILL WAIT AND SEE WHAT FUTURE GUIDANCE SUGGESTS ABOUT
CHANCES OF CONVECTION.

TEMPERATURES ACROSS THE REGION ARE EXPECTED TO REBOUND BY SUNDAY
WITH HIGHS IN THE LOW TO MID 70S POSSIBLE. BY MID WEEK THE HIGHS
ARE FORECAST TO BE UPPER 70S TO LOWER 80S. MINIMUM TEMPERATURES
WILL ALSO RISE DURING THIS PERIOD WITH LOWS APPROACHING MORE
NORMAL LEVELS BY MID WEEK.

&&

.MARINE...
THE COMBINATION OF NORTHERLY WINDS AND A SMALL LONG PERIOD SWELL
EAST OF PALM BEACH COUNTY WILL ALLOW THE GULF STREAM SEAS TO BUILD
TO NEAR 7 FEET TODAY. ALTHOUGH THE MORE HAZARDOUS SEAS ARE
EXPECTED TO BE IN THE OFF SHORE WATERS EAST OF PALM BEACH
COUNTY...GIVEN THE UNCERTAINTIES ALL OF THE LOCAL ATLANTIC WATERS
ARE IN A SMALL CRAFT ADVISORY TODAY. THE LONG PERIOD SWELL IS
FORECAST TO INCREASE BY SUNDAY NIGHT...WITH THE PERIOD EXPECTED TO
INCREASE TO ABOUT 11 SECONDS AND THE SWELL HEIGHT COULD REACH NEAR
4 FEET IN THE OFF SHORE WATERS EAST OF PALM BEACH COUNTY.

&&

.FIRE WEATHER...
A VERY STABLE AND DRY LOCAL ATMOSPHERE WILL CONTINUE TO CREATE
CONDITIONS THAT WILL ALLOW THE MINIMUM RELATIVE HUMIDITY TO GO
BELOW CRITICAL LEVELS TODAY...MAINLY ACROSS THE NORTHERN HALF OF
THE CWA WITH MINIMUM RH'S EXPECTED TO GO BELOW 35 PERCENT FOR FOUR OR
MORE HOURS WITH A RED FLAG WARNING IN EFFECT. ALTHOUGH WINDS LATER
THIS AFTERNOON COULD BECOME NNE AND BRING SOME LIMITED MOISTURE
ACROSS THE COASTLINE OF PALM BEACH AND BROWARD COUNTIES...THESE
AREAS ARE INCLUDED IN THE RED FLAG WARNING.

BY SUNDAY...THE SURFACE FLOW IS FORECAST TO BE MORE FROM THE NE
AND SHOULD BRING SOME MOISTURE ACROSS THE EASTERN HALF OF THE CWA.
THE WESTERN HALF HOWEVER...EXCLUDING MAINLAND MONROE COUNTY...WILL
STILL HAVE DEW POINTS LOW ENOUGH ALLOWING THE MINIMUM RH'S TO GO
BELOW CRITICAL LEVELS FOR FOUR OR MORE HOURS...WITH A FIRE WEATHER
WATCH IN EFFECT FOR GLADES...HENDRY AND COLLIER COUNTY...INCLUDING
THE NAPLES AREA.
