AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE AMARILLO TX 721 PM CDT MON AUG 20 2007 .AVIATION... ISOLATED THUNDERSTORMS WILL CONTINUE NEXT FEW HOURS ALONG SFC TROF IN WESTERN PANHANDLES. THESE STORMS SHOULD AVOID KAMA AND KDHT. SOME STORMS MAY MOVE NEAR KGUY THIS EVENING...BUT CLOUDS SHOULD DISSIPATE GENERALLY BY LATE TONIGHT. CU FIELD SHOULD ENSUE AGAIN TOMORROW WITH AMPLE MOISTURE AND STRONG HEATING ALL AREAS...YIELDING A SOMEWHAT TURBULENT BOUNDARY LAYER. ALTHOUGH A STRONG CAP WILL LIKELY BE IN PLACE...THERE MAY BE ENOUGH HEATING FOR CB DEVELOPMENT BY LATE AFTERNOON. WILL MONITOR FORECASTS TO CONSIDER INCLUDING REMARKS IN NEXT ISSUANCE. KRAMAR && .PREV DISCUSSION... /ISSUED 644 PM CDT MON AUG 20 2007/ UPDATE... SVR TSTM WATCH NUMBER 624 ISSUED WITH UPDATES TO PUBLIC PRODUCTS ISSUED. ANDRADE PREV DISCUSSION... /ISSUED 400 PM CDT MON AUG 20 2007/ DISCUSSION... MANY FALLEN TEMP RECORDS THIS AFTERNOON AS EFFICIENT HEATING AND DOWNSLOPING WINDS ALLOWED TRIPLE DIGIT HIGHS TO REACH THE CENTRAL TO WESTERN CWA. WITH THE SURFACE TROUGH SITTING ACROSS THE WESTERN PANHANDLES PROVIDING A FORCING MECHANISM....AND MOISTURE IN PLACE ACROSS MOST OF THE PANHANDLES...THINKING AN ISOLATED STORM OR TWO MAY FORM LATE THIS AFTERNOON OR EVENING. ALSO NOTICING A CU FIELD DEVELOPING NEAR THE SURFACE TROUGH ON VIS SAT...SO LEFT THE SLIGHT CHANCE POPS IN THROUGH 00Z. ANOTHER WARM DAY ON TAP FOR TOMORROW BUT APPEARS THE WIDESPREAD TRIPLE DIGIT VALUES WILL BE LESS LIKELY AS THE SURFACE TROUGH WILL RETREAT INTO SOUTHEAST COLORADO PROVIDING MAINLY SOUTH TO SOUTHEAST SURFACE WINDS FOR THE PANHANDLES. SO EXPECT MOISTURE RETURN TO THE WESTERN ZONES AND HIGH TEMPS TO DROP BY A FEW DEGREES. PATTERN BEGINS TO BECOME MORE UNSETTLED AFTER TUESDAY. THE SPLIT HIGH PATTERN WILL BREAK DOWN LEAVING SOUTHEAST HIGH IN PLACE...WITH THE SOUTHWEST HIGH WEAKENING. FLOW OVER THE PANHANDLES WILL BECOME VARIABLE UNTIL WEDNESDAY WHEN THE WINDS SHOW A MORE WESTERLY COMPONENT. WITH THE HIGH WEAKENING OVER THE SOUTHWEST US...THE PATTERN WILL BECOME MORE CONDUCIVE TO ALLOWING SHORT WAVES TO ENTER THE PANHANDLES. THE FIRST WAVE MAY IMPACT THE NORTHERN PANHANDLES AS EARLY AS WEDNESDAY EVENING. SO LEFT THE SLIGHT CHANCE POPS IN FOR NOW AND ALSO KEPT THE SLIGHTLY COOLER TEMPS IN PLACE. WILL THEN CONTINUE THE SLIGHT COOLING TREND THURSDAY AS ANOTHER WAVE TRACKS EAST OVER THE ROCKIES. WITH THE WEAKENING IN THE UPPER FLOW...MODELS ARE HINTING AT A WEAK FRONT PUSHING TOWARD THE PANHANDLES THURSDAY. HOWEVER...THE GFS AND DGEX BOTH STALL THE FRONT NORTH OF THE OKLAHOMA PANHANDLE SO THINKING ANY COOLING EFFECTS ASSOCIATED WITH THE FRONT WILL BE IN THE FORM OF CLOUD COVER OR POSSIBLY PRECIP FOR THE PANHANDLES. WITH THE UPPER HIGH OVER THE SOUTHEAST US HOLDING STEADY...TROPICAL MOISTURE ALOFT WILL BE STREAMING INTO THE PANHANDLES AND COME TO A PEAK ON SATURDAY. THE MOST PROMINENT SHORT WAVE OF THE WEEK WILL IMPACT THE PANHANDLES FRIDAY NIGHT INTO SATURDAY SO LIKEWISE HAVE THE HIGHEST POPS DURING THE TIME. A BIT CONCERNED THAT TEMPS ARE A FEW DEGREES TO WARM ON SATURDAY IF THIS PRECIP DOES MATERIALIZE. STUCK WITH MEX GUIDANCE FOR NOW...BUT WILL TREND DOWN IF PRECIP BECOMES MORE LIKELY. LEFT THE PREVIOUS PACKAGE IN TACT FOR SUNDAY AND MONDAY. JJB && .AMA WATCHES/WARNINGS/ADVISORIES... TX...NONE. OK...NONE. &&
