AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE AMARILLO TX 413 PM CDT THU JUL 8 2004 .DISCUSSION... STORMS FIRING ONCE AGAIN OVER NORTHEAST NEW MEXICO...THE WESTERN OKLAHOMA PANHANDLE...AND SOUTHEAST COLORADO. INCREASED POPS TO SCATTERED AREAL COVERAGE OVER THE NORTHWEST AND TAPERED TO ISOLATED IN THE SOUTHEAST THROUGH THE EVENING HOURS. ANY STORMS THAT DO DEVELOP HAVE THE POTENTIAL TO BECOME STRONG AND AN ISOLATED SEVERE STORM IS POSSIBLE (DALHART HAD A 49 KT GUST FROM LAST NIGHTS ACTIVITY). SURFACE TROUGH TO REMAIN SITUATED OVER THE SAME GENERAL AREA THROUGH FRIDAY. MID LEVEL TEMPS COOL SOMEWHAT BY FRIDAY AFTERNOON WHICH MAY INCREASE CHANCES FOR THUNDER MAINLY OVER THE NORTHWEST PORTIONS OF THE CWA IN CLOSER PROXIMITY TO THE TROUGH AXIS. POP STRUCTURE FOR FRIDAY VERY SIMILAR TO TODAY(HIGHEST NORTHWEST...LOWEST SOUTHEAST). BROAD RIDGE WILL BE IN PLACE ACROSS THE SOUTH CENTRAL US THROUGH THE UPCOMIMG WEEKEND. RETAINED LOW POPS ACROSS ALL AREAS THROUGH SUNDAY WITH MAINLY DIURNAL ACTIVITY EXPECTED. IN ADDITION...UPPER LOW OVER SOUTHEAST TEXAS IS PROGGED TO MOVE WESTWARD ACROSS SOUTH TEXAS THIS WEEKEND. NOT SURE HOW THIS WILL AFFECT THE PANHANDLES AS OF YET...HOWEVER...WE SHOULD SEE SOME MID LEVEL MOISTURE INCREASE AS A RESULT. THEREFORE...DECIDED TO TREND HIGH TEMPS DOWN A COUPLE OF DEGREES BOTH SATURDAY AND SUNDAY GIVEN ANTICIPATED INCREASED CLOUD COVER. MODELS CONTINUE TO RETROGRADE MID/UPPER RIDGE INTO THE FOUR CORNERS BY THE MIDDLE OF NEXT WEEK. THIS WOULD PLACE US BACK IN A NORTHWEST FLOW REGIME WITH A COOLER AND WETTER WEATHER PATTERN. GFS STILL HINTING AT A COLD FRONT APPROACHING THE AREA AROUND THE WED/THUR TIME FRAME. DECIDED NOT TO MAKE ANY CHANGES TO POPS IN THE EXTENDED AND WILL LET LATER SHIFTS LOOK FOR MORE CONSISTENCY IN MODEL TRENDS BEFORE BITING OFF ON THE GFS FORECAST. && .PRELIMINARY POINT TEMPS/POPS...
