AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL
233 PM EDT FRI JUN 15 2012

.SHORT TERM (TONIGHT-SUNDAY NIGHT)...
RECENTLY ANIMATED WATER VAPOR LOOP SHOWED A MID-LEVEL TROUGH
EXTENDING WSW FROM THE CAROLINAS TO THE CENTRAL GULF COAST SLOWLY
SHIFTING SOUTHWARD OVER NRN FLORIDA WITH PLENTY OF MID-LEVEL DRY
AIR SPREADING SOUTH ACROSS THE REGION IN ITS WAKE. THIS UPPER
TROUGH COMBINED WITH A SUFFICIENT AMOUNT OF LOW-LEVEL
MOISTURE/INSTABILITY ...A WEAK FRONTAL BOUNDARY OR TROUGH THAT WAS
ANALYZED EXTENDING WEST ACROSS S FLORIDA AND THE AFTERNOON SEA
BREEZES WILL SUPPORT ANOTHER ROUND OF AFTERNOON CONVECTION ONCE
AGAIN LATER TODAY. SIMILAR TO YESTERDAY...DECENT MID-LEVEL LAPSE
RATES WITH -9 C 500 MB TEMPS AND PRIMARILY LIGHT WESTERLY FLOW
THROUGH THE PROFILE WILL SUPPORT A FEW STRONG TO POSSIBLY SEVERE
STORMS WITH THE MAIN IMPACTS BEING LIGHTNING...PERIODS WITH HEAVY
RAINFALL...DAMAGING WIND GUSTS AND HAIL THROUGH THE MID-EVENING
PERIOD BEFORE TRENDING DOWN.

ON SATURDAY...THE MODELS INDICATE THE WEAK SURFACE BOUNDARY AND
UPPER TROUGH CONTINUING SOUTH OF THE PENINSULA WITH NORTHERLY FLOW
AND MUCH DRIER DEEP LAYER AIR SPREADING SOUTH INTO THE AREA THROUGH
THE COURSE OF THE DAY. HOWEVER...WE WILL KEEP ISOLATED/SCATTERED
SHOWERS AND STORMS IN THE FORECAST...ESPECIALLY ACROSS THE
SOUTHWESTERN PORTIONS OF THE PENINSULA ALONG THE GULF COAST WHERE
THE BESTS LOW-LEVEL CONVERGENCE WILL BE EXPECTED BETWEEN THE NELY
FLOW AND THE AFTERNOON GULF COAST SEA BREEZE.

SATURDAY NIGHT THROUGH SUNDAY NIGHT...MODEL PWAT VALUES CONTINUE TO
FALL AS THE DEEP LAYER DRY AIR SPREADS SOUTH ACROSS THE AREA.
ALTHOUGH THIS DRY AIR AND NORTHERLY FLOW WILL SUPPRESS AFTERNOON
CONVECTION...WILL KEEP A SLIGHT CHANCE OF SHOWERS IN THE
FORECAST...ESPECIALLY ACROSS THE ATLANTIC MARINE AREAS AND THE EAST
COAST LOCATIONS THROUGH THE OVERNIGHT/EARLY MORNING PERIODS WHERE
THE BEST CONVERGENCE WILL BE.

.LONG TERM...(MONDAY-THURSDAY)
MODELS INDICATE RISING UPPER HEIGHTS AS THE UPPER TROUGH BEGINS
TO LIFT ENE AWAY FROM THE LOCAL AREA THROUGH THE FIRST HALF OF THE
WEEK. DEEP EASTERLY FLOW WITH NEAR NORMAL TEMPERATURES WILL BE
EXPECTED EACH DAY THROUGH THIS TIME. THE BEST CHANCE FOR AFTERNOON
SHOWERS WILL REMAIN INLAND AND ALONG THE GULF COAST WITH THE
EASTERLY FLOW CONTINUING.

&&

.MARINE...
MODERATE NORTHEAST WINDS AND DRIER AIR WILL FILL IN ACROSS THE
MARINE AREAS OVER THE WEEKEND IN THE WAKE OF THE WEAK FRONTAL
BOUNDARY. THIS WILL TRANSLATE TO BUILDING SEAS...MAINLY OVER THE
ATLANTIC WATERS EAST OF PALM BEACH COUNTY ACROSS THE GULF STREAM
WHERE SEAS COULD REACH THE EXERCISE CAUTION LEVEL. WINDS WILL
STEADILY SHIFT TOWARD THE EAST THROUGH THE EARLY PORTION OF
THE UPCOMING WEEK AND REMAIN IN THE MODERATE RANGE THROUGH THE
MID-WEEK PERIOD.

&&

.FIRE WEATHER...
NO CONCERNS THROUGH THE PERIOD DESPITE THE DRIER AIR SPREADING
SOUTH INTO THE LOCAL AREA.
