AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL
155 PM EDT THU MAY 31 2001

SURFACE RIDGE BROAD AND WEAK OVER THE AREA AND SHOULD SHIFT
SOUTHWARD SOME AS MODELED.  THE TROUGH SURFACE AND ALOFT WILL MAKE
ITS PRESENCE FELT WITH AN INCREASE IN THE DEEP MOISTURE AND A RETURN
OF A MORE WESTERLY FLOW IN THE LOW LEVELS.  SO THE PATTERN WILL
FAVOR INCREASING PROBABILITIES FOR THE FORECAST AREA...WITH THE
HIGHEST PROBABILITIES IN THE EASTERN PORTIONS.  IF THE FORESTRY
OBSERVATIONS ARE CORRECT THEN WE ARE HITTING SOME UPPER 90S.  THAT
SEEMS A LITTLE HIGH HOWEVER I DO THINK WE COULD MAKE THE MID 90S
OVER THE INTERIOR.  SO WILL CONTINUE WITH THE PRESENT TYPE OF
FORECAST.

MYNN SOUNDING NOT MAKING IT INTO THE SYSTEM.  AS WE ARE NOW INTO THE
TROPICAL SEASON IT WOULD BE NICE IF THIS DATA WAS MAKING IT INTO THE
MODELS.  WITH ALL OF THE CLOUDS OVER THIS AREA THE GOES SOUNDER DATA
IS NOT AVAILABLE.

IN THE MARINE THE WINDS WILL BE A LITTLE STRONGER ON THE WEEKEND AS
THE TROUGH PASSES TO OUR NORTH.  HOWEVER THE WESTERLY DIRECTION FOR
THE EAST COAST AND OFFSHORE FLOW SHOULD KEEP THE SEAS GOOD FOR
BOATING.

IN THE EXTENDED WE STILL LOOK FOR THE SURFACE RIDGE TO SHIFT TO THE
NORTH OF OUR ZONES ALTHOUGH NOW NOT AS FAR NORTH.  THIS WILL STILL
PUT US IN THE EASTERLY LOW LEVEL FLOW.  SO AT THE BEGINNING OF NEXT
WEEK WE SHOULD FAVOR THE INTERIOR AND WESTERN ZONES FOR RAIN.  BY
THE END OF THE PERIOD ON THURSDAY THE DEEPENING OF THE UPPER TROUGH
OVER THE GULF OF MEXICO SHOULD BRING US BACK TO THE POINT OF THE
HIGH CLOUDS STREAMING OUT OF MEXICO AND ALTHOUGH PLENTY OF DEEP
MOISTURE NOT ENOUGH HEATING TO HAVE THE WIDESPREAD AFTERNOON
ACTIVITY.
