NWS Amarillo, TX wrote its last area forecast discussion before the first event at Aug 11, 5:42 PM CST, 34 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE AMARILLO TX 642 PM CDT THU AUG 11 2011 .AVIATION... A FEW CONCERNS FOR THIS TAF CYCLE. FIRST AND FOREMOST IS THE POTENTIAL FOR CONVECTION THIS EVENING. KEPT CB REMARKS AT ALL TERMINALS THROUGH 08Z...BUT THINK KAMA HAS THE BEST SHOT OF SEEING A DIRECT IMPACT. WENT AHEAD AND INSERTED A TEMPO GROUND FOR THUNDERSTORMS BETWEEN 01 AND 04Z AT KAMA. MVFR VSBYS AND GUSTY WINDS IN EXCESS OF 40 KT WILL BE POSSIBLE. SECOND CONCERN WILL BE THE POTENTIAL FOR LOW CIGS OVERNIGHT. MOISTURE DOES NOT LOOK TO BE AS DEEP AS THIS MORNING AND THERE WERE ONLY SHORT PERIODS OF MVFR CIGS. THEREFORE...WENT SLIGHTLY MORE OPTIMISTIC AND INCLUDED SCT020 AT ALL TERMINALS AFTER 08Z. IF ANY CIG RESTRICTIONS DO DEVELOP...EXPECT THEM TO BE RELATIVELY SHORT-LIVED /2-3 HOURS/. A COLD FRONT WILL APPROACH FROM THE NORTH TOMORROW AFTERNOON...WHICH SHOULD LEAD TO ANOTHER ROUND OF THUNDERSTORMS. INSERTED CB REMARKS AT ALL THREE TERMINALS FOR NOW AS CONFIDENCE IS TOO LOW TO MENTION ANY SPECIFIC IMPACTS THIS FAR OUT. COLD FRONT LOOKS TO MOVE THROUGH KGUY AND KDHT AFTER 21Z SO INCLUDED A WIND SHIFT IN THE TAFS. THE FRONT SHOULD HANG UP NORTH OF KAMA THROUGH THIS CYCLE. JACKSON && .PREV DISCUSSION... /ISSUED 342 PM CDT THU AUG 11 2011/ DISCUSSION... MAIN FORECAST CONCERNS WILL BE SHOWERS AND STORMS THROUGH THE EARLY PART OF NEXT WEEK. OUTFLOW FROM MORNING CONVECTION HAS KEPT FRONT FROM RETREATING FURTHER BACK TO THE NORTH TODAY. HOWEVER...JET STREAK AT 250MB ALONG WITH A SHORTWAVE TROUGH MOVING THROUGH THE AREA HAS LED TO SHOWERS AND THUNDERSTORMS REDEVELOPING THIS AFTERNOON. THUNDERSTORMS HAVE DEVELOPED ON THE HIGHER TERRAIN OF NEW MEXICO AND SHOULD SPREAD EASTWARD THROUGH THE AFTERNOON/EVENING. LATEST SPC MESOANALYSIS SHOWS SBCAPES HAVE INCREASED TO AROUND 2500 J/KG WITH DCAPES RUNNING ABOUT 1000 TO 1500 J/KG. A FEW STRONG TO POSSIBLY SEVERE WIND GUSTS AND LARGE HAIL WOULD BE POSSIBLE UNDERNEATH THE STRONGEST CORES. HEAVY RAINFALL COULD ALSO MATERIALIZE AS PWATS CLIMB TO 1.3 TO 1.4 INCHES...WHICH IS WELL ABOVE NORMAL FOR THIS TIME OF YEAR. WILL CARRY 20 TO 30 POPS THROUGH 12Z. WARMER TEMPERATURES ARE ANTICIPATED ON FRIDAY IN ADVANCE OF THE NEXT COLD FRONT. LOWER 90S IN THE NORTHWEST TO NEAR 100 IN THE SOUTHEAST LOOK REASONABLE. KEPT SOME LOW POPS BETWEEN 12Z AND 18Z TOMORROW AS CONVECTIVE OUTFLOW AND THE LLJ COULD KEEP ACTIVITY GOING INTO THE MORNING HOURS. THUNDERSTORMS WILL DEVELOP AGAIN TOMORROW AFTERNOON AND EVENING WITH NORTHWEST FLOW ALOFT PREVAILING AND A COLD FRONT ENTERING THE AREA. THE INHERITED 30 TO 40 POPS ACROSS THE AREA FOR FRIDAY NIGHT REMAIN VALID. DAMAGING WINDS WOULD BE POSSIBLE IF THUNDERSTORMS ARE ABLE TO DEVELOP INTO A CONVECTIVE COMPLEX. SATURDAY WILL BE A FEW DEGREES COOLER DUE TO INCREASED CLOUD COVER BEHIND THE FRONT. TEMPS SHOULD RANGE FROM THE MID 80S IN THE NORTHWEST TO MID 90S...AND MAY BE ACTUALLY OVERDONE IF CLOUD COVER HANGS TOUGH. POST FRONTAL UPSLOPE WITH CONTINUED NORTHWEST FLOW ALOFT WILL BRING ADDITIONAL CHANCES FOR SHOWERS AND THUNDERSTORMS. UPPER LEVEL RIDGE WILL ATTEMPT TO SHIFT EASTWARD LATE INTO THE WEEKEND. UPPER LEVEL FLOW BECOMES MORE SOUTH SOUTHWESTERLY WITH UPPER LEVEL IMPULSE MOVING NORTHWEST OF THE FORECAST AREA. TAPERED POPS ON SUNDAY FROM 30 IN THE NORTHWEST/NORTH TO AROUND 15 IN THE FAR SOUTHEAST. INTO EARLY NEXT WEEK...UPPER LEVEL RIDGE WILL REMAIN NEARBY. NO POPS ARE IN THE FORECAST BEYOND MONDAY NIGHT. HOWEVER...ISOLATED ACTIVITY DUE TO DAYTIME HEATING COULD DEVELOP UNDERNEATH THE UPPER RIDGE BUT DO NOT BELIEVE IT IS WORTH A MENTIONABLE POP ATTM. AFTER SLIGHTLY COOLER TEMPS OVER THE WEEKEND...AFTERNOON HIGHS WILL WARM BACK UP INTO THE MID/UPPER 90S. MEX NUMBERS WERE GENERALLY ACCEPTED DURING THIS TIME. FIRE WEATHER... ELEVATED TO CRITICAL FIRE WEATHER CONDITIONS ARE NOT EXPECTED THROUGH THE FORECAST PERIOD. && .AMA WATCHES/WARNINGS/ADVISORIES... TX...NONE. OK...NONE. && 13/03
