AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL
408 AM EDT THU APR 1 2010

.UPDATE...HAVE ADDED AREAS OF FOG OVER THE INTERIOR ZONES AS A
COUPLE OF OUR INLAND SITES ARE REPORTING DENSE FOG AND THE HENDRY
COUNTY SHERIFF OFFICE IS REPORTING VERY LOW VISIBILITY. ALSO
SENDING OUT A DENSE FOG ADVISORY.

&&

.PREV DISCUSSION... /ISSUED 354 AM EDT THU APR 1 2010/

DISCUSSION...A MID LEVEL RIDGE WILL BUILD INTO THE FL PENINSULA
FROM THE GOFMEX TODAY AS A STRONG SHORT WAVE TROUGH MOVES INTO THE
ROCKY MOUNTAIN WEST. THIS RIDGE WILL HOLD FIRM ACROSS THE REGION
THROUGH EARLY NEXT WEEK ALTHOUGH WEAKENING SLIGHTLY BY THE END OF
THE PERIOD AS SEVERAL SHORT WAVE TROUGHS MOVE THROUGH THE MID
LATITUDES. A SURFACE RIDGE WILL ALSO BE IN PLACE INITIALLY
CENTERED OVER THE PENINSULA AND THEN RIDGING ALONG THE ATLANTIC
COAST WHICH IN TURN WILL INCREASE THE GRADIENT ACROSS SOUTH
FLORIDA GIVING A STRONGER EASTERLY FLOW. THIS PROCESS WILL BEGIN
HAPPENING TONIGHT AND CONTINUE INTO THE FIRST HALF OF THE WEEKEND.
THE RIDGE WILL THEN SHIFT SOUTH AGAIN AND STRETCH ITSELF ALONG 30N
LATE INTO THE WEEKEND CONTINUING INTO NEXT WEEK. THIS ENTIRE
PATTERN WILL KEEP SOUTH FLORIDA DRY WITH EVEN VERY FEW CLOUDS.
SOME STRATOCU MAY BEGIN TO STREAM IN FROM THE ATLANTIC AS THE EAST
FLOW BECOMES INCREASINGLY DEEPER. BUT EVEN THEN FORECAST SOUNDINGS
KEEP PWAT AT VERY LOW LEVELS. THERE WILL ALSO BE A WARMING TREND
THROUGH THE PERIOD WITH AFTERNOON TEMPERATURES CLIMBING INTO THE
LOWER AND MID 80S AND NIGHTTIME READINGS AROUND 60 INTERIOR AND
LOWER TO MID 60S ALONG BOTH COASTS.

MARINE...A LONG PERIOD SMALL NORTHEAST SWELL WILL CONTINUE TO
AFFECT THE NORTHERN PORTIONS OF THE ATLANTIC WATERS THROUGH FRIDAY
AND THEN DIMINISH. OTHERWISE, GOOD BOATING WEATHER IS ANTICIPATED
THROUGH THE PERIOD.

FIRE WEATHER...TEMPERATURES DID NOT WARM ENOUGH YESTERDAY IN MANY
AREAS FOR THE RELATIVE HUMIDITY TO FALL BELOW 35 PERCENT. THIS
WILL BE THE SAME SITUATION TODAY ALONG WITH SOME MODIFICATION AT
LOW LEVELS. STILL, IT SEEMS THAT SOME VERY DRY AIR ALOFT COULD MIX
DOWN WITH ENOUGH HEATING BUT MAINLY OVER INTERIOR PORTIONS. THUS,
WILL ISSUE RED FLAG WARNING FORM INLAND PALM BEACH, INLAND
COLLIER, HENDRY AND GLADES COUNTIES. FURTHER MODIFICATION WILL
OCCUR ON FRIDAY AND NO PROBLEMS ARE FORESEEN AT THIS TIME INTO THE
WEEKEND.
