VERY IMPRESSIVE SEVERE THUNDERSTORM HAS MOVED INTO TYLER COUNTY THIS EVENING...WHICH APPEARS TO BE MOVING SOUTHEASTWARD ALONG THE STATIONARY FRONT. OTHER THUNDERSTORMS CONTINUE TO DEVELOP TO ITS NORTH. 4.0KM WRF MODEL SUGGESTS THIS ACTIVITY MAY CONTINUE THROUGH MIDNIGHT.

SHAMBURGER && .PREV DISCUSSION... /ISSUED 641 PM CDT TUE AUG 25 2009/ DISCUSSION... A STATIONARY FRONT EXTENDS SOUTH THROUGH TYLER TO HIGH ISLAND ..DIFFUSING OVER THE NORTHWEST GULF OF MEXICO.

AIR QUALITY ALERT MESSAGE AQALCH ALREADY OUT. JS PREV DISCUSSION... /ISSUED 247 PM CDT TUE AUG 25 2009/ SYNOPSIS...AS EXPECTED THAT PESKY FRONTAL BOUNDARY IS IN THE PROCESS OF WASHING OUT IN EAST TEXAS WITH ONLY WEAK CONVERGENCE AND A BROADENING MOISTURE PATTERN LEFT BEHIND TO MARK ITS EXISTANCE. REMAINING MOISTURE AND JET ENERGY COULD BE ENOUGH TO MAINTAIN A MINIMAL CHANCE OF SHOWERS AND POSSIBLY A THUNDERSTORM OVER WESTERN PORTIONS OF CENTRAL LOUISIANA AS WELL AS SOUTHEAST TEXAS TONIGHT. A BROAD MID LEVEL CUTOFF LOW MOVING SLOWLY WESTWARD INTO THE LOWER MISSISSIPPI VALLEY WILL PROVIDE JUST ENOUGH SUBSIDENCE AND DRIER AIR FROM THE NORTH TO HOLD PRECIP CHANCES BELOW MENTIONABLE LEVELS OVER THE REMAINDER OF THE AREA TONIGHT. ALTHOUGH THE LOW STALLS OVER THE LOWER MISSISSIPPI VALLEY THROUGH THE REMAINDER OF THE WEEK, THIS SYSTEM LOOKS TO BE MOISTURE STARVED. LAWN WORK MAY NEED TO BE COMPLETED EARLY THIS WEEK AS RAIN CHANCES WILL RAMP UP FRIDAY THROUGH THE WEEKEND THANKS TO A SLOW MOVING CANADIAN COLD FRONT MOVING IN FROM THE NORTHWEST AND CREEPING THROUGH BEFORE STALLING OFF THE COAST EARLY NEXT WEEK. SHORT TERM...A GRADUAL WARMING TREND ON OVERNIGHT TEMPS AS THE AIRMASS MODIFIES IN THE WAKE OF THE WASHED OUT FRONTAL BOUNDARY TO THE WEST. WENT HIGHER THAN GUIDANCE ON TEMPS DUE TO CLOUDCOVER AS WELL AS HIGHER DEW POINTS THAN PROGGED ACROSS THE I-10 ZONES. THE MODIFYING TREND CONTINUES ON WEDNESDAY THANKS TO CLOUDS PERSISTING INTO EARLY AFTERNOON. SHADED TEMPS JUST BELOW GFS GUIDANCE. LONG TERM...AS MENTIONED, RAIN CHANCES INCREASE FRIDAY INTO THE WEEKEND AND ON INTO TUESDAY AS WE REMAIN WITHIN THE COOLER SIDE OF A STATIONARY FRONTAL BOUNDARY.
