Area forecast discussion, Aug 9, 2:37 PM EDT, 41 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL
237 PM EDT SAT AUG 9 2014

.SHORT TERM (TONIGHT-MONDAY NIGHT)...
A DEEP LAYER RIDGE WILL REMAIN ACROSS SOUTH FLORIDA THROUGH THE
WEEKEND AND INTO EARLY NEXT WEEK. ALL OF THE SHORT TERM MODEL
GUIDANCE AGREES WITH THIS SCENARIO. THIS WILL ALLOW FOR A LIGHT
SOUTHERLY STEERING FLOW TO CONTINUE. DRIER AIR FROM THE BAHAMAS WILL
ALSO FILTER IN ACROSS THE REGION WITH FORECAST SOUNDINGS SHOWING
PWAT LOWERING TO AROUND 1.5 INCHES ON SUNDAY AND POSSIBLY LESS
THAN 1.25 INCHES BY MONDAY AFTERNOON. AT ANY RATE, THUNDERSTORM
COVERAGE WILL BE LESS EACH AFTERNOON THROUGH THE BEGINNING OF THE
WEEK. THE GREATEST CHANCES FOR RAIN EACH DAY WILL BE THE LAKE
REGION THROUGH THE AFTERNOON AND EVENING PERIODS.

.LONG TERM (TUESDAY-SATURDAY)...
LITTLE CHANGE IS EXPECTED THROUGH THE EXTENDED PERIOD OF THE
FORECAST BUT THERE COULD BE SOME MOISTURE INCREASE AGAIN BY THE
MIDDLE OF THE WEEK. STEERING FLOW WILL MAINTAIN A MOSTLY SOUTHERLY
DIRECTION AS THE DEEP LAYER RIDGE REMAINS IN CONTROL AND SEA BREEZES
DEVELOP ALONG BOTH COASTS DURING THE AFTERNOONS. SO THE BEST CHANCES
FOR RAIN INTO THE END OF NEXT WEEK WILL BE ACROSS THE INTERIOR AND
LAKE REGIONS.

&&

.MARINE...
A LIGHT EAST TO SOUTHEAST WIND FLOW WILL CONTINUE THROUGH THE
PERIOD WITH SEAS OF LESS THAN 4 FEET EXPECTED. LOCALLY ROUGH SEAS
MIGHT DEVELOP NEAR DAILY AFTERNOON AND EVENING THUNDERSTORMS.

WATER LEVELS MAY RUN SLIGHTLY ABOVE NORMAL COMBINED WITH THE
UPCOMING LUNAR PERIGEE ON SUNDAY AND THIS COULD RESULT IN SOME
MINOR STREET FLOODING OVER THE TYPICAL MIAMI BEACH AREAS ALONG THE
BAY SIDE. THIS WILL BE MONITORED OVER THE WEEKEND ESPECIALLY
DURING THE HIGH TIDE CYCLES SUNDAY INTO MONDAY.
