AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SHREVEPORT LA 333 PM CDT THU OCT 2 2014 .DISCUSSION... BIG STORY OF THIS FCST CYCLE CONTINUES TO BE THE PENDING SEVERE WEATHER EVENT EXPECTED TO UNFOLD THIS AFTERNOON/TONIGHT. SHORTWAVE CONTINUES TO DIG EWD INTO N TX...AND RIGOROUS CONVECTION IS ALREADY ONGOING ACROSS N TX/CENTRAL OK. THIS WILL QUICKLY PIVOT EWD THIS AFTERNOON/EVENING INTO OUR NWRN AREAS...AND EVENTUALLY ACROSS THE ENTIRE REGION BY EARLY FRIDAY MORNING. SEVERE THUNDERSTORM WATCH 518 REMAINS IN EFFECT FOR PARTS OF E TX/SE OK THROUGH 02Z...WITH MORE WATCHES LIKELY TO COME DOWNSTREAM. SETUP FOR SEVERE THUNDERSTORMS CONTINUES TO TAKE SHAPE...AS TODAY'S SCT CONVECTION HAS DONE LITTLE TO AFFECT THE OVERALL AMPLE INSTABILITY ACROSS THE REGION. CONSIDERING THE POTENT UPPER LEVEL SUPPORT IN THE SHORTWAVE...THE STRONG SURFACE FORCING WITH THE FRONT...SUFFICIENT /ALTHOUGH MOSTLY UNIDIRECTIONAL/ SHEAR...AND AMPLE INSTABILITY... WE SHOULD SEE A FAIRLY WIDESPREAD SEVERE WEATHER EVENT. GREATEST THREATS CONTINUE TO BE DAMAGING STRAIGHT-LINE WINDS AND LARGE HAIL. AS ALWAYS...CANNOT RULE OUT AN ISOLD TORNADO OR TWO. LATEST MODEL RUNS SHOWING GOOD AGREEMENT WITH RESPECT TO TIMING OF THE FRONT/SQUALL LINE...AND THE RAPID EWD PROGRESSION SHOULD KEEP ANY FLOODING THREAT AT BAY. CONVECTION WILL CLEAR THE REGION FOR THE MOST PART BY FRIDAY MORNING...WITH SKIES QUICKLY CLEARING AND COOLER TEMPS OVERTAKING THE REGION. BELOW NORMAL TEMPS ARE EXPECTED TO HOLD ON THROUGH MUCH OF THE WEEKEND...BEFORE WARMING UP TO NEAR AND ABOVE NORMAL BY MIDWEEK. ANOTHER COLD FRONT PROGGED TO MOVE THROUGH THE REGION DURING TUESDAY MAY BRING SOME ADDITIONAL CHANCES FOR RAIN...BUT NOT MUCH OF A COOL-DOWN. /12/ && .PRELIMINARY POINT TEMPS/POPS...
