AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LAKE CHARLES LA 406 PM CDT SAT JUN 9 2007 .DISCUSSION...DESPITE COPIOUS MOISTURE AND INSTABILITY ACROSS THE AREA SHOWN BY LAPS SOUNDINGS WITH PWATS OF 1.8 INCHES AND SBCAPES AOA 3000J/KG...CONVECTIVE ACTIVITY HAS BEEN QUITE PALTRY AND VERY LIMITED IN COVERAGE. LOOKS LIKE WHAT REMAINS OF SFC FRONT AND A COUPLE OF SHORTWAVES ARE DRIVING THE PRIMARY AREAS OF THUNDERSTORMS...ONE OVER NE TX/NW LA...AND THE OTHER OVER SE LA EASTWARD INTO THE FL PANHANDLE. BOTH NAM AND GFS CONTINUE TO SHOW CONVECTION BACKING INTO EASTERN AND SOUTHEASTERN PARTS OF THE CWA THIS EVENING...BUT GIVEN THEIR OVERZEALOUSNESS WITH QPF OVER THE AREA TODAY AND THAT THIS ACTIVITY IS LARGELY DIURNALLY DRIVEN...WILL CONTINUE WITH SLIGHT CHANCE ONLY.

WILL HAVE TO SEE WHERE ANY RESIDUAL OUTFLOW BOUNDARIES WIND UP BEFORE CONSIDERING ANYTHING HIGHER THAN A 20 POP. OTHERWISE...RIDGING ALOFT AND AT THE SFC WILL HOLD FIRM THROUGH THE UPCOMING WEEK...BEFORE AN UPPER LOW/TROF DROPS INTO EASTERN TEXAS FOR THE WEEKEND. ENJOY THE HEAT AND HUMIDITY...CAUSE ITS GOING TO BE HERE FOR A WHILE. && .AVIATION... DAYTIME HEATING COMBINED WITH A MOIST AND UNSTABLE ATMOSPHERE WILL PRODUCE A FEW SHOWERS AND THUNDERSTORMS FOR THE REMAINDER OF THE AFTERNOON UNTIL SUNSET. THE BEST CHANCE FOR SHOWER ACTIVITY LOOKS TO BE AT THE KAEX AND KLFT AREAS WHERE LOW LEVEL CONVERGENCE MAY BE A LITTLE BETTER NEAR THE ATCHAFALAYA BASIN. OTHERWISE...EXPECT SCATTERED TO BROKEN CU TO REMAIN AT VFR LEVELS. OVERNIGHT...WITH DECENT LOW LEVEL MOISTURE LINGERING BELOW NOCTURNAL INVERSION...EXPECT SOME LOW CLOUDS AND PATCHY FOG TO DEVELOP THAT WILL LOWER AT TIMES TO THE MVFR RANGE. && .MARINE...LIGHT AND MAINLY SOUTHERLY WINDS AND RELATIVELY CALM SEAS WILL CONTINUE WITH HIGH PRESSURE AT THE SFC AND ALOFT. && .PRELIMINARY POINT TEMPS/POPS...
