AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSONVILLE FL
251 PM EDT MON JUL 25 2011

.SHORT TERM...
MEAN HIGH PRESSURE RIDGE IS SOUTH OF THE AREA AND
A TROUGH IS PUSHING ACROSS THE EASTERN SEABOARD. SEVERAL
SHORTWAVES ARE MOVING THRU THE BASE OF THE MID LEVEL TROUGH. THIS
ENERGY IS COMBINING WITH THE GULF COAST SEA BREEZE TO PRODUCE A
BAND OF STRONG STORMS OVER THE SW PORTION. CONVECTION WILL MOVE
TOWARD THE NE THIS AFTN/EVNG. HAVE BUMPED POPS UP TO LIKELY
THROUGHOUT THE MIDDLE PORTION OF NE FL FOR REMAINDER OF THE AFTN.
THE LAPS SHOWS CAPES OF 4000 J/KG FROM GILCHRIST TO ST. JOHNS.

TUESDAY/WEDNESDAY...A STRONGER SHORTWAVE TROUGH AND ASSOCIATED
COLD FRONT MOVING INTO SRN GA WILL USHER IN DEEPER MOISTURE WITH
PWATS APPROACHING 2.5 INCHES...TAPERING DOWN TO LESS THAN 2
INCHES OVER MARION COUNTY. SOUTHWESTERLY FLOW AGAIN TUESDAY WILL
KEEP EAST COAST SEA BREEZE PINNED TO THE COAST AGAIN AND
COLLISIONS WILL BE LIKELY NEAR ST. JOHNS RIVER. NUMEROUS
SHOWERS/STORMS ARE FORECAST FOR MOST OF THE LOCAL AREA AND SCTD
STORMS FOR THE FAR SRN TIER. LOCALLY HEAVY RAINFALL IS POSSIBLE.
MAX TEMPS WILL BE A TAD LOWER (UPR 80S TO LOW 90S) DUE TO
INCREASED CLOUDS AND SHOWERS.

.LONG TERM...THURSDAY THROUGH MONDAY...
DEEP MOISTURE WILL LINGER OVER THE AREA ON THURSDAY WITH ABOVE
CLIMO POPS ESPECIALLY N OF I-10 AS MOISTURE IS IN PROCESS OF
LIFTING N WITH THE FRONT. WILL KEEP HIGH END SCTD SHOWERS/STORMS.
HIGH PRESSURE WILL BUILD BACK OVER THE AREA THROUGH THE WEEKEND
WITH DRIER AIR IN MID/UPR LEVELS. THIS SHOULD LOWER POPS BACK
BELOW AVERAGE WITH ABOVE NORMAL TEMPS. HEAT INDICES MAY BE
OPPRESSIVE ONCE AGAIN AND TOP OUT NEAR 105 THIS WEEKEND.

EARLY NEXT WEEK...THE UPR RIDGE IS PROGGED TO RETROGRADE WEST AND
TROUGHINESS RETURNS TO THE EAST COAST WITH A BETTER CHANCE FOR
RAIN AND NOT AS HOT. HAVE LEANED TO THE GFS WITH THIS FCST AS THE
ECMWF LOWERS A FRONT INTO S GA LATE SUNDAY...EARLIER THAN THE GFS.

.AVIATION...

INSTABILITY INDUCED BY SURFACE HEATING WILL CONTINUE TO LEAD TO

DISSIPATE THIS EVENING AFTER SUNSET...ADDITIONAL CONVECTION

NORTHWEST. THE TROUGH WILL PUSH TOWARD THE SOUTHEAST US COAST
TUESDAY...AND BECOME A FOCUS FOR ADDITIONAL CONVECTION
TUESDAY...ESPECIALLY IN THE AFTERNOON.

&&

.MARINE...

A SURFACE TROUGH WILL MOVE TOWARD THE SOUTHEAST US COAST
