AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE AMARILLO TX 1158 PM CDT WED AUG 12 2009 .UPDATE... MAIN REASON FOR UPDATE WAS TO ADJUST POPS AND TO CLEAN UP EVENING WORDING IN THE ZPF. CURRENT WATER VAPOR IMAGERY INDICATES SHORTWAVE TROUGH IN NE CO. THIS HAS TRIGGERED AN AREA OF THUNDERSTORMS WHICH CONTINUE TO ACCELERATE SWD ACROSS THE TX/OK PANHANDLES. WENT AND ADJUSTED POPS UPWARD WITH THE HIGHEST POPS ACROSS THE CENTRAL AND ERN SECTIONS OF THE AMA CWA. ALTHOUGH NO OTHER SHOWERS AND THUNDERSTORMS HAVE DEVELOPED UPSTREAM...STILL MAINTAINED SLIGHT CHANCE POPS ACROSS THE REMAINDER OF THE PANHANDLES AS THE AFOREMENTIONED SHORT WAVE TROUGH IS FORECAST TO DROP THROUGH THE PANHANDLES OVERNIGHT. CLK && .AVIATION... FOR THE 06Z TAFS...MAIN FORECAST CONCERN IS ON CONVECTION CHANCES IN THE VERY SHORT TERM. THUNDERSTORM COMPLEX IS TRACKING SWD ACROSS THE PANHANDLES. GIVEN CURRENT TRACK...TIMED STORMS TO AFFECT THE KAMA TERMINAL BETWEEN 06-08Z. STILL POSSIBLE FOR ADDITIONAL STORMS TO POP UP OVERNIGHT AS A SHORTWAVE TROUGH PROPAGATES INTO THE PANHANDLES...HOWEVER CONFIDENCE IS LOW ENOUGH TO PRECLUDE ANY MENTION AT KDHT/KGUY. UPPER RIDGE EDGES OVER TX THURSDAY...BUT WITH NW FLOW ALOFT...CAN EXPECT ANOTHER REPEAT PERFORMANCE ON MOUNTAIN CONVECTION MAKING ITS WAY INTO THE AREA. FOR NOW JUST INSERTED CB REMARKS AFTER 00Z AS EXPECT DRY CONDITIONS DURING THE DAY. WINDS WILL GENERALLY REMAIN OUT OF THE SOUTH WITH SPEEDS AROUND 12-15 KTS. CLK && .PREV DISCUSSION... /ISSUED 910 PM CDT WED AUG 12 2009/ UPDATE... COMPLEX OF STRONG THUNDERSTORMS MOVING ACROSS SE CO/SW KS IN ASSOCIATION TO A SHORTWAVE TROUGH DROPPING SEWD ALONG THE NORTHERN PERIPHERY OF THE UPPER RIDGE CENTERED OVER THE FOUR CORNERS REGION. THE 00Z SOUNDING AT DDC INDICATES AN INVERTED TYPE V PROFILE...INDICATING STRONG WINDS WOULD BE THE MAIN THREAT FROM ANY STORMS THAT MIGRATE INTO THE NRN SECTIONS OF AMA CWA. GIVEN STORM MOVEMENT TO THE SOUTHEAST...WENT AND BUMPED UP POPS ACROSS THE OK PANHANDLE THIS EVENING. ALTHOUGH CURRENT RADAR IMAGERY DOES NOT SHOW MUCH ELSE IN THE WAY OF CONVECTION IN NE NM...HELD ONTO POPS OVERNIGHT AS ANY OUTFLOW BOUNDARY MAY TRIGGER ADDITIONAL STORMS WHILE A LLVL JET INTENSIFIES ACROSS THE AREA. REMAINDER OF FORECAST LOOKS ON TRACK WITH ONLY MINOR ADJUSTMENTS MADE TO TEMP/WIND/DEWPOINT/QPF GRIDS. CLK PREV DISCUSSION... /ISSUED 557 PM CDT WED AUG 12 2009/ AVIATION... A NORTHWEST FLOW ALOFT WILL BRING THUNDERSTORMS FROM EASTERN COLORADO AND EASTERN NEW MEXICO INTO THE PANHANDLES TONIGHT. ALL THREE TAF SITES HAVE A SHOT AT A TSRA WITH DHT HAVING THE BEST CHANCE. SKIES WILL CLEAR AGAIN THURSDAY MORNING. THEN TSRA MAY GET CLOSE TO THE DHT TAF SITE JUST BEFORE THE END OF THIS FORECAST. SOUTHEAST AND SOUTH WINDS WILL PREVAIL. VFR CONDITIONS WILL PREVAIL OUTSIDE OF THUNDERSTORMS. PREV DISCUSSION... /ISSUED 246 PM CDT WED AUG 12 2009/ DISCUSSION... UPPER LEVEL PATTERN CONTINUES WITH A RIDGE ACROSS THE SOUTHWEST DESERTS AND A TROUGH IN THE NORTHWEST AND ACROSS THE APPALACHIANS IN THE EAST. THROUGH THE NEXT SEVEN DAYS THE NORTHWEST TROUGH WILL DIG INTO THE WESTERN UNITED STATES AND SUPPRESS THE FOUR CORNERS RIDGE. RIDGE REDEVELOPS OVER THE SOUTHEASTERN UNITED STATES. THE WESTERN TROUGH WILL BE THE PREDOMINANT WEATHER PLAYER FOR THE PANHANDLES IN THE EXTENDED FORECAST. THUNDERSTORMS ALREADY DEVELOPING ALONG THE HIGHER TERRAIN OF NEW MEXICO AND COLORADO THIS AFTERNOON. SHORTWAVE TROUGH OVER THE FOUR CORNERS IS EXPECTED TO INCREASE THIS ACTIVITY THROUGH THE EVENING AND OVERNIGHT TONIGHT. THUNDERSTORMS WILL LIKELY DRIFT DOWN INTO THE PANHANDLES LATE IN THE EVENING AND SPREAD ACROSS THE AREA OVERNIGHT. CANNOT RULE OUT ISOLATED THUNDERSTORMS DEVELOPING IN THE PANHANDLES THIS AFTERNOON...BUT THE MAIN SHOW WILL BE TONIGHT. POPS HAVE BEEN INCREASED DURING THE OVERNIGHT HOURS...FITTING WELL WITH RECENT TRENDS OF NIGHTTIME CONVECTION. RIDGE BEGINS TO WEAKEN AND MOVE ACROSS THE PANHANDLES ON THURSDAY. SLIGHTLY WARMER TEMPERATURES ARE EXPECTED ESPECIALLY IN THE SOUTHERN TEXAS PANHANDLE. AS FLOW BECOMES WESTERLY...CANNOT RULE OUT STORMS DEVELOPING OVER THE MOUNTAINS AND DRIFTING INTO THE WESTERN PANHANDLES OR DEVELOPING WITHIN THE LEE TROUGH ITSELF IN THE EVENING. SHORTWAVE TROUGH TRAVERSES THE SOUTHERN ROCKIES AND PASSES OVER THE PANHANDLES ON FRIDAY WITHIN THE SOUTHWESTERLY FLOW ALOFT...INCREASING THE CHANCES FOR THUNDERSTORMS. INCREASED POPS INTO THE 30 TO 40 PERCENT RANGE...WHICH AGREES WELL WITH THE MAV AND MET GUIDANCE FOR FRIDAY NIGHT. NEXT BIG FEATURE IS A COLD FRONT WHICH MOVES INTO THE PANHANDLES SATURDAY NIGHT AND SUNDAY AS THE WESTERN TROUGH MOVES INTO THE NORTHERN PLAINS. THIS WILL SERVE AS A FOCUS FOR THUNDERSTORM DEVELOPMENT ON SUNDAY...AND THUS 30 TO 40 POPS HAVE BEEN ADDED HERE AS WELL. HIGH TEMPERATURES WILL BE COOLER ON SUNDAY AS WELL...ESPECIALLY IN THE NORTH. FRONT LINGERS IN THE REGION THROUGH MONDAY...SO POPS HAVE BEEN CONTINUED THROUGH MONDAY NIGHT. ANOTHER COLD FRONT MAY MOVE INTO THE AREA WEDNESDAY. GENERALLY UNDERCUT THE MAV GUIDANCE FOR MAX AND MIN TEMPERATURES IN THE FIRST FEW PERIODS...FOLLOWING RECENT TRENDS. GENERALLY STAYED WITH THE 00Z MEX GUIDANCE IN THE EXTENDED FORECAST. KIMBLE FIRE WEATHER... FIRE WEATHER CONCERNS ARE LOW DUE TO RECENT HEAVY PRECIPITATION AND THE CONTINUED CHANCES FOR PRECIPITATION. RELATIVE HUMIDITIES WILL REMAIN HIGH WITH WINDS GENERALLY LESS THAN 20 KT. KIMBLE && .AMA WATCHES/WARNINGS/ADVISORIES... TX...NONE. OK...NONE. && 15/05
