AREA FORECAST DISCUSSION...CORRECTED NATIONAL WEATHER SERVICE MIAMI FL 206 PM EDT TUE AUG 14 2012 .SHORT TERM...TONIGHT THROUGH FRIDAY...AN UPPER LEVEL RIDGE SHOULD CONTINUE TO EXTEND FROM THE GULF OF MEX AND ACROSS THE PENINSULA, WHILE THE LOW LEVEL ATLANTIC RIDGE WILL CONTINUE JUST NORTH OF THE LOCAL AREA ACROSS CENTRAL FLORIDA. WHILE THE UPPER RIDGE WILL CONTRIBUTE TO LIMIT WIDESPREAD PRECIP ACTIVITY BY WAY OF MODERATE SUBSIDENCE, SOMEWHAT DEEPER EASTERLIES AROUND THE BASE OF THE SURFACE ATLANTIC RIDGE WILL HELP TO TRANSPORT MOISTURE FROM THE TROPICAL ATLANTIC OVER SOUTH FLORIDA.

ISOLATED TO WIDELY SCT NIGHTTIME/EARLY MORNING ACTIVITY COULD ALSO OCCUR ALONG THE EAST COAST AND ATLANTIC WATERS. NEAR SEASONAL AFTERNOON TEMPS SHOULD CONTINUE TO BE EXPECTED ALONG COASTAL AREAS DURING THIS PERIOD, BUT COULD SOAR TO THE MID 90S ACROSS PORTIONS OF THE INTERIOR.
