AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LAKE CHARLES LA 1233 PM CDT FRI SEP 25 2009 .AVIATION... CLDS XPCD TO REMAIN ANCHORED OVER THE AREA THROUGH THE AFTERNOON HOURS AS THE WARM FRONT BACKS UP TO THE NORTHWEST. SHWRS IN THE GULF ARE MOVING NORTHWEST FOLLOWING THE RETREATING FRONT. THIS LOOKS TO BRING SHOWERS/TSTMS INTO ARA AND THE INTO LFT BY THE LATE AFTERNOON HOURS. THE RETREATING FRONT LOOKS TO MAKE ITS WAY INTO LCH/BPT THIS EVE WITH WIDELY SCATTERED SHWRS PSBL. && .PREV DISCUSSION... /ISSUED 1037 AM CDT FRI SEP 25 2009/ UPDATE... SATELLITE IMAGERY THIS MORNING SHOWS WIDESPREAD LOW CLOUDS BLANKET THE INLAND ZONES AND NEARSHORE COASTAL WATERS...WITH SCATTERED CUMULUS IN THE OFFSHORE WATERS. HOWEVER...BREAKS ARE ALREADY BEGINNING TO APPEAR IN THE CLOUD DECK ACROSS ACADIANA. MUCH LIKE YESTERDAY EXPECTING THE LOW CLOUD DECK TO BREAK UP FROM EAST TO WEST THIS AFTERNOON...BUT IT IS UNCERTAIN HOW FAR WEST THIS WILL OCCUR. HAVE LOWERED HIGH TEMPS IN SOUTHEAST TEXAS AND WESTERN LOUISIANA FOR TODAY WHERE CLOUD COVER IS MOST LIKELY TO LINGER...BUT RAISED THEM IN THE EASTERN ZONES WHERE TEMPS SHOULD RISE QUICKLY WITH SKIES BECOMING PARTLY CLOUDY THIS AFTERNOON. CURRENT RADAR IMAGERY SHOWS SCATTERED SHOWERS AND THUNDERSTORMS IN SE LA AND THE OUTER COASTAL WATERS. MOS GUIDANCE APPEARS TO STILL BE OVERDOING POPS FOR THE CWA AS IT HAS BEEN THE PAST SEVERAL DAYS...AND HAVE TWEAKED PRECIP CHANCES DOWNWARD WITH HIGHEST LEVELS IN THE SOUTHEASTERN ZONES. MADE OTHER VARIOUS ADJUSTMENTS TO GRIDS WITH FORECAST PRODUCTS ALREADY SENT. SHAMBURGER PREV DISCUSSION... /ISSUED 647 AM CDT FRI SEP 25 2009/ AVIATION... GULF EASTERLIES CONTINUE TO ASCEND ANTICYCLONICALLY WHEN IMPINGING UPON THE FRONTAL SURFACE...UPGLIDING OVER THE RECENTLY-ARRIVED GREAT-PLAINS AIR. IFR CEILINGS WILL SLOWLY LIFT INTO THE MVFR CATEGORY BY MIDMORNING. ISOLATED SHOWERS EMBEDDED IN STRATUS ARE POSSIBLE THROUGHOUT THE DAY. PREV DISCUSSION... /ISSUED 522 AM CDT FRI SEP 25 2009/ SYNOPSIS...A STATIONARY BOUNDARY FROM LOWER ACADIANA OUT SOUTHWEST OVER THE COASTAL WATERS HAS GOOD UPPER LEVEL JET SUPPORT TO THE WEST. THIS FRONT SHOULD WEAKEN AND WASH OUT HOWEVER AS HIGH PRESSURE BUILDS FROM THE EAST. AREA RADARS SHOWING LIGHT SHOWER ACTIVITY OVER THE LAKES AREA OF SOUTHEAST TEXAS INTO CENTRAL LOUISIANA AS WELL AS ISOLATED SHOWERS OVER THE COASTAL WATERS. WILL KEEP A CHANCE OF LIGHT SHOWERS IN THE FORECAST TODAY THANKS TO THE PERSISTENT COMBINED PACIFIC AND GULF MOISTURE RIDING ISENTROPICALLY OVER THE FRONTAL SURFACE TODAY. A SHORTWAVE OVER THE NORTHWESTERN GULF WILL MOVE TOWARDS OUR AREA AROUND THE PEREPHERY OF THE MID LEVEL RIDGE OVER THE EASTERN GULF. ALTHOUGH CONVECTIVE TEMPS WILL FIND IT TOUGH GOING TO BE ACHIEVED, THERE WILL BE SUFFICIENT H3 DIVERGENCE FOR OCNL RUMBLES OF THUNDER TODAY. SHORT TERM...NOT MUCH HAS CHANGED IN OUR REASONING WITH CHANCE POPS WITH LIGHT AMOUNTS TODAY. MOST OUTDOOR ACTIVITIES CAN GO ON WITH ONLY NUISANCE PRECIP COVERING WIDE AREAS. MID LEVEL RIDGING WILL HELP TO KEEP CONVECTION AT BAY EXCEPT FOR THE SHORTWAVE ENERGY INTO THE BPT AND LCH AREAS. THOSE AREAS WILL ALSO SEE A SLIGHT BOOST IN UPWARD MOTION LATE TNITE THANKS TO A HINT OF A RIGHT REAR QUAD OF THE SUBTROPICAL JET. PERSISTENCE IS THE WORD ON TEMPS. LONG TERM...AFTER ONE MORE DAY OF SCATTERED LIGHT SHOWERS ON SATURDAY, THE LARGE SCALE UPPER TROF WILL SWING THROUGH AROUND SUNDOWN EFFECTIVELY ENDING OUR RAIN CHANCES WITH RIDGING FROM THE WEST. SUBSIDENCE AND A LACK OF CLOUD COVER WILL ALLOW TEMPS TO SOAR ABOVE NORMAL ON SUNDAY. RAIN CHANCES INCREASE TOWARDS THE END OF THE WEEK AS A VIGOROUS UPPER TROF WITH AN ASSOCIATED PACIFIC COLD FRONT APPROACHES THE AREA. MODELS DIVERGE GREATLY ON THE TIMING. CHOSE TO LEAN TOWARDS THE MORE CONSERVATIVE AND SLOWER EURO MODEL. MARINE...PERSISTENT GRADIENT WINDS OVER THE WESTERN WATERS WILL DIMINISH LATE TODAY AS THE FRONT WEAKENS. MAINTAINING A CAUTION FOR THOSE WATERS. 11 && .PRELIMINARY POINT TEMPS/POPS...
