AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE FORT WORTH TX 334 PM CDT SUN AUG 23 2009 .DISCUSSION... SCATTERED THUNDERSTORMS WILL CONTINUE FIRE THIS AFTERNOON AND EVENING...ESPECIALLY ALONG A STATIONARY BOUNDARY LOCATED NEAR A GRAHAM...HILLSBORO...TO HEARNE LINE. THESE STORMS WILL ALSO PRODUCE MULTIPLE OUTFLOW BOUNDARIES WHICH WILL BE THE CATALYST FOR ADDITIONAL DEVELOPMENT. MUCH LIKE YESTERDAY...ALL STORMS SHOULD WEAKEN AND EVENTUALLY DISSIPATE SHORTLY AFTER SUNSET. THE MAIN HAZARD ASSOCIATED WITH ANY STORMS THIS AFTERNOON/EVENING WILL BE FROM DOWNBURST WINDS. UPPER LEVEL HIGH PRESSURE WILL BUILD SLOWLY EASTWARD ON MONDAY AND SHOULD SUPPRESS CONVECTION ACROSS THE WESTERN HALF OF THE REGION. WE WILL HOLD ON TO SOME LOW POPS ACROSS THE EAST DURING THE AFTERNOON WHERE MOISTURE AND INSTABILITY WILL BE MOST FAVORABLE. THUNDERSTORM CHANCES WILL DECREASE TUESDAY AND WEDNESDAY WITH INCREASING LARGE SCALE SUBSIDENCE. HOWEVER...A FEW STORMS MAY DEVELOP EACH AFTERNOON NEAR THE EXTREME EASTERN ZONES. FOR NOW WILL JUST HOLD ON TO 10 PERCENT POPS. THE UPPER LEVEL PATTERN SHOULD BECOME A BIT MORE INTERESTING LATE IN THE WEEK AS THE UPPER RIDGE BUILDS OVER THE WESTERN U.S. AND ALLOWS A SERIES OF SHORT WAVES TROUGHS TO SWING ACROSS THE PLAINS AND INTO TEXAS. BOTH THE GFS AND THE ECMWF HAVE BEEN FAIRLY CONSISTENT ON THE TIMING OF A COLD FRONT EXPECTED THURSDAY NIGHT/FRIDAY. ALTHOUGH...THE MODELS ARE NOT IN COMPLETE AGREEMENT ON THE STRENGTH OR ORIENTATION. THE MODELS ALSO DISAGREE ON THE AMOUNT OF PRECIP ALONG AND BEHIND THE FRONT WITH THE ECMWF BEING THE WETTER OF THE TWO SOLUTIONS. FOR NOW...WE WILL HOLD ON TO LOW (20 TO 30 PERCENT) POPS FROM THURSDAY NIGHT THROUGH SUNDAY AND AWAIT ADDITIONAL GUIDANCE. TEMPERATURES THE NEXT FEW DAYS WILL BE NEAR OR SLIGHTLY ABOVE SEASONAL NORMALS WITH HIGHS IN THE MIDDLE AND UPPER 90S AND LOWS MOSTLY IN THE 70S. TEMPERATURES BEHIND THE FRONT WILL BE A BIT COOLER WITH HIGHS FROM THE UPPER 80S TO THE MIDDLE 90S AND LOWS IN THE UPPER 60S TO LOWER 70S. && .PRELIMINARY POINT TEMPS/POPS... DALLAS-FT.
