AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAKE CHARLES LA
455 PM CDT FRI SEP 12 2014

.DISCUSSION...
CDFNT HAS SAGGED A LITTLE MORE TO THE SOUTH...AND IS CURRENTLY
ANALYZED NEAR A MARKSVILLE TO FORT POLK TO LUFKIN LINE.  FARTHER
SOUTH...AN INVERTED TROF IS PUSHING WWD INTO THE TX COAST...WITH
THE FLOW AROUND THIS FEATURE AND A MID/UPPER LEVEL RIDGE TO THE
EAST IMPARTING A DEEP SOUTH/SOUTHEAST FETCH. SCATTERED SHOWERS AND
THUNDERSTORMS CONTINUE FROM THE VICINITY OF THE FRONT SOUTHWARD
INTO THE GULF WATERS. GIVEN PWATS GREATER THAN 2 INCHES...CELLS
ARE AND WILL CONTINUE TO BE EFFICIENT RAINFALL PRODUCERS. LOCALLY
HEAVY RAINFALL IS POSSIBLE...AND WAS INSERTED INTO THE GRIDS FOR
THIS EVENING.

THE FRONTAL BOUNDARY IS EXPECTED TO CONTINUE SWD...CLEARING THE
COAST SOMETIME EARLY SATURDAY MORNING...WHERE IT IS FCST TO
SUBSEQUENTLY STALL. MEANWHILE...THE INVERTED TROF WILL CONTINUE
WWD WHILE THE RIDGE TO THE EAST ALSO EXPANDS WWD...TURNING OUR
ONSHORE FLOW INTO ONE MORE PARALLEL TO THE COAST OR SLIGHTLY
OFFSHORE. WHILE LOW TO MID LEVEL MOISTURE WILL REMAIN SUFFICIENT
FOR CONVECTION TOMORROW...EXPECT MUCH LESS IN THE WAY OF
COVERAGE. CONSIDERABLE POST FRONTAL CLOUD COVER AND COOLER THERMAL
PROFILES WILL YIELD COOLER AFTERNOON TEMPERATURES...GENERALLY IN
THE LOWER TO PERHAPS MID 80S.

COOLEST NIGHT OF THE PERIOD SATURDAY NIGHT INTO SUNDAY
MORNING...WITH LOWS FALLING INTO THE MID/UPPER 60S AWAY FROM THE
COAST. EVEN LESS CONVECTION SUNDAY WITH THE RIDGE AT PEAK
INTENSITY...THOUGH THAT WILL START TO CHANGE ON MONDAY AS THE
TROPICAL WAVE/LOW CURRENTLY OVER FLORIDA MAKES ITS WAY INTO THE
WESTERN GULF. THIS SYSTEM WILL FIND ITSELF IN ONLY A MARGINALLY
FAVORABLE ENVIRONMENT THROUGHOUT ITS JOURNEY ACROSS THE GULF...AS
UPPER LEVEL WINDS ARE PROGGED TO REMAIN RATHER ROBUST OUT OF THE
NORTHEAST ACROSS THE EAST/SOUTHEAST GULF. THE SHEAR IMPROVES OVER
THE WEST/NORTHWEST GULF MON AND TUE...BEFORE MID LATITUDE
WESTERLIES ASSOCIATED WITH A DIGGING EASTERN CONUS TROF INTRUDE.
THIS FEATURE WILL RESULT IN ANOTHER CDFNT CROSSING THE AREA ON
WED...WITH THE POTENTIAL FOR INTERACTION WITH THE TROPICAL
WAVE/LOW RESULTING IN ANOTHER DECENT RAIN EVENT TUE INTO WED.

.MARINE...
A COLD FRONT IS EXPECTED TO MOVE INTO THE COASTAL WATERS LATE
TONIGHT INTO EARLY SATURDAY...WITH OFFSHORE WINDS DEVELOPING IN
ITS WAKE. THE FRONT IS FORECAST TO STALL AND ONLY GRADUALLY
DISSIPATE. SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS ARE
EXPECTED TONIGHT AND SATURDAY...WITH CHANCES DECREASING SUNDAY AS
MID TO UPPER LEVEL RIDGING BUILDS OVERHEAD. WINDS WILL TURN MORE
SOUTHERLY EARLY IN THE NEW WEEK AS AN AREA OF LOW PRESSURE TRACKS
WESTWARD ACROSS THE GULF OF MEXICO...WITH AN INCREASE IN RAIN
CHANCES AS THE RIDGE ALOFT WEAKENS AND THE LOW PRESSURE AREA
TRACKS THROUGH THE WESTERN GULF.
