AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE AMARILLO TX 554 PM CDT WED JUN 18 2008 .AVIATION... SHORT TERM AVIATION CONCERN WILL BE THUNDERSTORM POTENTIAL. APPEARS KDHT AND KGUY ARE MOST LIKELY TO EXPERIENCE THUNDER WITHIN THE NEXT FEW HOURS SO INSERTED A VCTS GROUP. HOWEVER...RADAR TRENDS INDICATE THE STORMS ARE WEAKENING AS THEY MOVE INTO THE PANHANDLES SO NOT CONFIDENT TEMPO GROUPS FOR -TSRA WILL DEVELOP. ANTICIPATE IFR TO MVFR CIGS DEVELOPING OVERNIGHT AFTER THE PRECIP DISSIPATES...WITH CIGS LIFTING AFTER 18 OR 19Z IF NOT SOONER. A FEW CLOUDS MAY LINGER DURING THE AFTERNOON TOMORROW...WITH CU REDEVELOPING NEAR THE END OF THE CURRENT TAF CYCLE. WINDS SHOULD GENLY REMAIN OUT OF THE SOUTH TO SOUTH EAST...AND INCREASE SOME TONIGHT AS THE LL JET INTENSIFIES. MAY THEN SEE A BRIEF WIND LUL NEAR SUNRISE. JJB && .PREV DISCUSSION... /ISSUED 343 PM CDT WED JUN 18 2008/ DISCUSSION... MODELS CONTINUE TREND OF UPPER RIDGE OVER THE SOUTHWEST...WITH NORTHWEST FLOW ALOFT FOR THE PANHANDLES THROUGH THE WEEKEND. THUS...MADE FEW CHANGES TO PREVIOUS PACKAGE AND BLENDED CLOSE WITH THE GFS AND NAM SOLUTIONS. WITH THAT IN MIND...UPPED POPS FOR THIS EVENING. PRECIP ALREADY MOVING INTO NORTHWEST CWA FROM CONVECTION DEVELOPING OFF THE ROCKIES...AND ANTICIPATE THE LARGE COMPLEX IN EASTERN COLORADO MOVING SOUTHEAST TONIGHT AND IMPACT THE EASTERN PANHANDLES THIS EVENING. MENTIONED SEVERE IN THE DAY 1 TIME FRAME...AND LEFT HIGH QPF VALUES ACROSS THE EAST FOR TONIGHT. MAIN SEVERE CONCERN WILL ONCE AGAIN BE HAIL AND WINDS...BUT ISOLATED SUPER CELLS MAY AGAIN BE POSSIBLE GIVEN THE AMOUNT OF UNSTABLE AIR AND STEEP MID LEVEL LAPSE RATES. TUCUMCARI PROFILER SHOWING WINDS TRYING TO BACK IN THE LL EARLIER THAN YESTERDAY...ALTHOUGH 18Z AMARILLO SOUNDING SHOWED WEAK LL WINDS AND A WEAK CAP IN PLACE. DO NOT ANTICIPATE CAPPING TO BE AN ISSUE AS AIRMASS CONTINUES TO WARM...AND THINKING THE LL JET INCREASING AGAIN TONIGHT. NOTICED MODELS KEEP A MILD EARLY MORNING DRYING TREND OVER THE NEXT FEW DAYS BY DROPPING DEW POINT 5 TO 10 DEGREES FROM AFTERNOON HIGHS. PLUS WIND SPEEDS SHOULD GENERALLY DECREASE DURING THE EARLY MORNING AS THE INVERSION DEVELOPS. SO FELT GUIDANCE WAS RUNNING A FEW DEGREES TO WARM ON MORNING LOWS...SO ADJUSTED APPROPRIATELY. COULD NOT IDENTIFY ONE ABSOLUTELY DRY DAY THROUGH MONDAY SO FELT SOME POPS WERE WARRANTED EACH DAY UNTIL THE RIDGE TRIES TO BUILD FURTHER EAST TUESDAY AND FORCES PRICIP NORTH AND EAST OF THE PANHANDLES. AT THE SAME TIME...APPEARS ANY OF THE DEVELOPING STORMS COULD BECOME SEVERE WITH THE AMOUNT OF MOIST UNSTABLE AIR IN PLACE THROUGH THE WEEKEND. ONCE THE RIDGE BUILDS MORE OVER THE PANHANDLES TUESDAY AND WEDNESDAY...THINKING TEMPS WILL HAVE A BETTER CHANCE TO INCREASE DURING THE AFTERNOON HOURS. GFS INDICATES 850MB TEMPS WILL RISE INTO THE 30 TO 35C RANGE...WITH A 594 UPPER HIGH PARKS OVER THE PANHANDLES. THIS WOULD SUPPORT HIGHS IN THE UPPER 90S TO EVEN A FEW 100 DEGREES...BUT WITH THE MOISTURE STILL SEEMINGLY IN PLACE...THINKING THE TRIPLE DIGITS MAY BE DIFFICULT TO ACHIEVE. SO GENERALLY STAYED IN THE UPPER 90S. JJB FIRE WEATHER... FEW FIRE WEATHER CONCERNS THROUGH THE WEEK...WITH LIGHTNING STRIKES BEING THE ONLY FIRE WEATHER ISSUE. && .AMA WATCHES/WARNINGS/ADVISORIES... TX...NONE. OK...NONE. && 14/14
