AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE AMARILLO TX 600 PM CDT WED 09 JUL 2003 SFC TROUGH IS SLOWLY MOVING SOUTHEASTWARD BISECTING THE CWA FROM NE TO SW. GIVEN THE STOUT CAP...SHALLOW DEPTH OF THE TROUGH AND A LACK OF LIFT...HAVE REMOVED POPS FOR TONIGHT AND ADDED CLEAR SKY WORDING. OTHERWISE THE FCST APPEARS WELL IN HAND. ...PREVIOUS DISCUSSION BELOW... 240 PM CDT WED 09 JUL 2003 MAIN FORECAST CHALLENGE WILL BE LOWS TONIGHT AND TOMORROW AS WELL AS PRECIP CHANCES ON FRI. THE COLD FRONT HAS MOVED THROUGH THE WESTERN COUNTIES AND SHOULD BEGIN TO MOVE THROUGH THE CENTRAL AND EASTERN PANHANDLES AROUND SUNSET. LOWER DEWPOINTS BEHIND THE FRONT SHOULD ALLOW FOR SLIGHTLY LOWER MIN TEMPS TONIGHT WITH THE COLDEST MORNING BEING FRI WHEN WINDS ARE LIGHTEST. GOOD INSOLATION SHOULD KEEP HIGHS IN THE 90S. THE BEST CHANCE FOR POPS SHOULD BE LATE FRI AS A WEAK UPPER LEVEL DISTURBANCE MOVES ACROSS THE CENTRAL PLAINS IN THE NORTHWEST FLOW. MODELS TRY TO BREAK OUT SOME QPF ACROSS MAINLY THE NORTHERN PANHANDLES HOWEVER LAPSE RATES ARE NOT IMPRESSIVE SO WILL STICK WITH SLT CHANCE POPS FOR NOW. THE FOUR CORNERS HIGH BUILDS EAST NEXT WEEK ENSURING WARM TEMPS AND NO POPS THROUGH THE END OF THE PERIOD.
