SOUTHWEST LOUISIANA AND SOUTHEAST TEXAS FORECAST DISCUSSION NATIONAL WEATHER SERVICE LAKE CHARLES LA 255 PM CDT SAT JUN 30 2001 WITH SOUTHWEST FLOW AT THE SURFACE MOST OF THE SHOWERS AND THUNDERSTORMS HAVE BEEN EAST OF A LEESVILLE TO LAKE CHARLES LINE. AS YET...NO REAL GOOD CELL MERGERS TO PRODUCE ANY PULSE SEVERE WEATHER...HOWEVER A QUICK INCH OF RAIN IN 45 MINUTES HAS PUSHED THE VERMILION RIVER BACK OVER FLOOD STAGE AS OF A FEW MINUTES AGO. MID AND UPPER LEVEL TROF EXTENDING FROM THE MID MISSISSIPPI VALLEY SOUTH INTO THE NORTHWEST GULF IS EXPECTED TO MOVE SOUTH AND SOUTHWEST OVER THE NEXT COUPLE OF DAYS. WITH MOIST AND UNSTABLE AIRMASS IN PLACE (PWAT 1.75 INCHES AND CAPES OVER 3000 J/KG) WILL CONTINUE ABOVE CLIMO POPS FOR SUNDAY. WITH RELATIVELY COOL POOL ALOFT ON SUNDAY STILL COULD SEE ONE OR TWO PULSE SEVERE STORMS. ON MONDAY...WESTERLY MOVING TROPICAL WAVE ALONG THE NORTHERN GULF SHOULD BE IMPACTING THE AREA. MOISTURE VALUES INCREASE FURTHER WITH MEAN RELATIVE HUMIDITY OVER 75% AND PWAT NEARING 2 INCHES. WITH THIS DEEP MOISTURE AND SOME WARMING IN THE MID LEVELS...LESS LIKELY TO SEE ANY SEVERE STORMS BUT HEAVY RAINFALL COULD BE A PROBLEM. EXTENDED...TROPICAL WAVE WILL MEET UP WITH UPPER LEVEL TROF AND PUSH EAST OF THE AREA ON TUESDAY. HOWEVER...STILL ENOUGH MOISTURE TO PRODUCE DIURNAL SHOWERS AND STORMS THROUGH THE HOLIDAY INTO THE LATTER PARTS OF THE WEEK. 7-RUA .LCH...NONE. .PRELIM NUMBERS...
