AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL
222 PM EDT TUE MAY 1 2012
.SHORT TERM...TONIGHT THROUGH FRIDAY...A LOW LEVEL TROUGH OVER THE
EASTERN GULF OF MEXICO WILL CONTINUE TO MOVE WEST AS A HIGH PRESS
RIDGE BUILDS OVER THE SERN U.S. AND THE ADJACENT ATLANTIC WATERS.
THIS WILL RESULT IN A GRADUAL DRYING TREND STARTING TONIGHT. A
DEEP LAYER RIDGE IS EXPECTED TO BUILD FROM THE GULF OF MEX NORTH
ACROSS THE ERN THIRD OF THE COUNTRY AND THIS WILL ACCENTUATE THE
DRYING FURTHER MORE BY WAY OF STRONG SUBSIDENCE. STILL ISOLATED
AFTERNOON SHWRS/TSTMS COULD OCCUR AS SEA BREEZES COLLIDE OVER
INLAND AREAS. MORE SUNSHINE COUPLED WITH THE SUBSIDENCE ALOFT
WILL ALSO RESULT IN AFTERNOON TEMPS CLIMBING UP TO THE M/U 80S
ESPECIALLY ACROSS INTERIOR AND WEST THROUGH THIS PERIOD.
MODERATE TO STRONG E-SE WINDS TONIGHT AND EARLY WEDNESDAY WILL
CONTINUE TO LEAD TO A HIGH RISK OF RIP CURRENTS ALONG THE ATLANTIC
BEACHES THROUGH TONIGHT.
.LONG TERM...SATURDAY THROUGH TUESDAY...THE DEEP LAYER RIDGE AND
ASSOCIATED SUBSIDENCE SHOULD CONTINUE TO INDUCE DRY CONDITIONS
THROUGH MOST OF THIS PERIOD. THE ONLY EXCEPTION COULD BE LATE
SUNDAY OR MONDAY WHEN A WEAK FRONTAL BOUNDARY COULD GET CLOSE
