AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SHREVEPORT LA 840 PM CDT TUE MAY 26 2009 .DISCUSSION... OUTFLOW BOUNDARY HAS PUSHED WELL SOUTH AND EAST OF THE REGION THIS EVENING...THUS ANY FURTHER REDEVELOPMENT SHOULD STAY SOUTH AND EAST OF THE REGION OVERNIGHT. HOWEVER...FURTHER UPSTREAM...A WHOLE DIFFERENT SCENARIO IS TRYING TO TAKE SHAPE. MUCH OF NORTH TEXAS...SOUTHEAST OKLAHOMA AND SOUTHWEST ARKANSAS WAS UNTOUCHED FROM CONVECTION EARLIER TODAY...THUS INSTABILITY IS STILL RATHER STRONG ACROSS THE MIDDLE RED RIVER VALLEY. COMBINE THIS WITH A NORTH TO SOUTH OUTFLOW BOUNDARY NEAR THE I-35 CORRIDOR WHERE PRESENT CONVECTION IS FEEDING OFF OF NEAR THE DFW METROPLEX AND IS TRYING TO EXPAND NORTH AND EAST ALONG THE RED RIVER. 00Z SFC ANALYSIS SHOWING STRONG COLD FRONT BEHIND THIS CONVECTION...EXTENDING FROM NEAR PNC AND SPS ONTO NEAR LBB. FRONT IS MAKING MUCH QUICKER PROGRESS THAN 18Z PROGS INDICATED SO FOR THE UPDATE...WILL FOLLOW THE LATEST RUC GUIDANCE WHICH HAS THE FRONT ENTERING OUR EXTREME NW ZONES DURING THE PREDAWN HOURS. LOWERED POPS TO SLIGHT CHANCE VARIETY FOR OUR EASTERN TWO THIRDS BUT DID KEEP CHANCE POPS GOING IN OUR WEST AND NW ZONES JUST IN CASE PREFRONTAL CONVECTION CONTINUES TO SUSTAIN ITSELF. OTHERWISE... FEEL LIKE WE COULD SEE SOME ADDITIONAL DEVELOPMENT TONIGHT ON THE FRONT ITSELF BUT THAT WOULD BE WELL AFTER MIDNIGHT. TEMPS IN GOOD SHAPE SO NO OTHER CHANGES NECESSARY. UPDATE OUT SHORTLY. 13 && .AVIATION... QUIET IN THE WAKE OF AN AFTERNOON UPPER LEVEL DISTURBANCE NOW PUSHING ACROSS THE MISSISSIPPI RIVER. FARTHER WEST...ANOTHER GENTLE PUSH OVER MEXICO HAS MORE CONVECTION OVER THE RIO GRANDE AND PORTIONS OF NORTH TEXAS ALONG AN OUTFLOW. ALSO...A COLD FRONT IS POISED TO MOVE ACROSS THE FOUR STATE AREA OVER THE NEXT 12 TO 24 HRS. ADDITIONAL SHOWERS AND TSTMS MAY DEVELOP/ORGANIZE OVERNIGHT AND CONTINUE ALONG THE COLD FRONT BY 12Z AFFECTING TERMINALS FROM WEST TO EAST. OTHERWISE...VISIBILITIES OF 3SM AND SOME ISOLATED IFR DECKS CAN BE EXPECTED ACROSS RAIN SOAKED SITES 12Z TO 15Z...FOLLOWED BY OTHER REDUCTIONS ASSOCIATED WITH IMPENDING WEATHER. OTHERWISE... LIGHT AND VARIABLE WINDS TONIGHT WILL SHIFT TO THE NW 10KTS AS THE FRONT MOVES THROUGH THE REGION DURING WEDNESDAY KTYR BY 12Z TO KMLU BY 21Z. /24/ && .PRELIMINARY POINT TEMPS/POPS...
