NWS Amarillo, TX wrote its last area forecast discussion before the first event at May 25, 6:08 PM CST, 2 hours 26 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE AMARILLO TX 708 PM CDT SAT MAY 25 2013 .UPDATE... HAVE UPDATED GRAPHICAL FORECASTS...INCREASING THUNDERSTORM POPS/COVERAGE SIGNIFICANTLY ACROSS SOUTHWESTERN AND WESTERN SECTIONS OF PANHANDLES. LINE OF THUNDERSTORMS DETECTED BY KAMA 88D OVER EASTERN NEW MEXICO IS BEING SUPPORTED BY MODEST SHORTWAVE TROF AS IT MOVES TOWARD RICHER MOISTURE AND HIGHER INSTABILITY. UPDATED TEXT PRODUCTS WILL BE ISSUED SHORTLY. COCKRELL && .PREV DISCUSSION... /ISSUED 406 PM CDT SAT MAY 25 2013/ DISCUSSION... REGIONAL VISIBLE SATELLITE SHOWS SMALL CU DEVELOPMENT ACROSS THE SOUTHWESTERN TEXAS PANHANDLE WHILE CONVECTION HAS DEVELOPED ALONG THE NEW MEXICO MOUNTAINS AND SOUTHEASTERN COLORADO. THIS DEVELOPMENT WAS FAIRLY CAPTURED BY THE TTU WRF. WHAT THAT MEANS FOR THIS EVENING AND TONIGHT IS THAT THERE REMAINS A CHANCE FOR PRECIPITATION ALONG THE WESTERN HALF OF THE TEXAS AND OKLAHOMA PANHANDLE. ALSO GIVEN THE ELEVATED INSTABILITY AND WEAK DEEP LAYER SHEAR AN ISOLATED STRONG TO LOW END SEVERE STORM MAY BE POSSIBLE. ANY CONVECTION THAT MAY FORM SHOULD END BY MIDNIGHT. SUNDAY WILL BE A DAY TO KEEP AN EYE ON AS FAR AS FIRE WEATHER IS CONCERNED. THE DRYLINE IS EXPECTED TO ONCE AGAIN RETURN TO THE TEXAS AND OKLAHOMA PANHANDLES AND DROP RELATIVE HUMIDITIES BELOW 15 PERCENT ACROSS THE NORTHWESTERN TEXAS AND WESTERN OKLAHOMA PANHANDLES. THIS WILL LEAD TO ELEVATED AND CRITICAL FIRE WEATHER CONDITIONS FOR SUNDAY AFTERNOON. HOWEVER...THE ONGOING DROUGHT HAS LIMITED FUEL LOADING IN THIS AREA...AND THE RECENT RAINS FROM LAST NIGHT HAS PROVIDED DECENT MOISTURE TO WHAT FUELS THERE ARE. ANOTHER WRENCH IN THE MACHINE IS THE POTENTIAL FOR ADDITIONAL MOISTURE FROM ANY STORMS THAT COULD MAKE IT INTO THAT AREA TONIGHT. SHOULD THIS AREA RECEIVE NO RAIN TONIGHT THEN A FIRE WEATHER WATCH OR EVEN A RED FLAG WARNING MAY BE NEEDED FOR SUNDAY AFTERNOON. MONDAY COULD ALSO BE A DAY WHERE ELEVATED TO NEAR CRITICAL FIRE WEATHER CONDITIONS OCCUR...BUT THERE WILL ALSO BE RAIN CHANCES ACROSS THE EASTERN TEXAS AND OKLAHOMA PANHANDLES. SHOULD ANY OF THESE SHOWERS DEVELOP FURTHER WEST THAN CURRENTLY FORECASTS THEN FIRE WEATHER CONDITIONS COULD BE GREATLY HINDERED. TUESDAY AND WEDNESDAY LOOK TO BE THE TIME FRAME WITH THE GREATEST PRECIPITATION CHANCES AS WELL AS POTENTIAL FOR SEVERE WEATHER. WITH THAT BEING SAID THE SEVERE THREAT MAY BE SLIGHTLY LESS THAN WHAT APPEARED YESTERDAY. MEDIUM RANGE MODELS ARE BEGINNING TO CONVERGE ON A CONSENSUS AS TO THE TRACK OF THE UPPER LEVEL TROUGH BUT STILL DISAGREE ON EXACT TIMING. TREND WISE THE ECMWF HAS TRENDED BACK TOWARD THE GFS ON THE EVOLUTION OF THE SYSTEM SO HAVE LEANED MUCH CLOSER TO THE GFS RATHER THAN THE GFS. WITH THIS EVOLUTION AN OPEN WAVE WILL DROP OVER NEVADA AND UTAH DURING THE DAY ON TUESDAY. A LEADING SHORTWAVE TROUGH MOVES ACROSS THE PANHANDLES SPARKING SCATTERED SHOWERS AND THUNDERSTORMS. THE MAIN WAVE MOVES TO THE PANHANDLES AND TAKES ON A VERY SLIGHT NEGATIVE TILT. THIS ORIENTATION WOULD PLACE THE DRY SLOT ACROSS THE NORTHWESTERN TEXAS PANHANDLE AND WESTERN OKLAHOMA PANHANDLE WHILE CONVECTION FIRES ACROSS THE REST OF THE PANHANDLES. CAPE VALUES AT THIS TIME RANGE FROM 1500 TO 2200 J/KG WITH DEEP LAYER SHEAR OF 35 TO 40 KT. BUFR SOUNDINGS SHOW A WEAK CAP WHICH COULD BE THE SAVINGS GRACE TO KEEP SEVERE WEATHER LIMITED. BUT SHOULD THE SYNOPTIC FORCING OVERCOME THIS CAP THEN WE COULD BE LOOKING AT A ORGANIZED CONVECTION WITH LARGE HAIL AND DAMAGING WIND AS THE PRIMARY THREATS ACROSS THE EASTERN HALF OF THE TEXAS AND OKLAHOMA PANHANDLE. AS STATED YESTERDAY KEEP ANY EYE ON THIS PORTION OF THE FORECAST AS IT WILL LIKELY CHANGE AS WE GET CLOSER TO THESE DAYS. FLOW ALOFT BECOMES MORE ZONAL THURSDAY AND FRIDAY TO LIMIT PRECIP CHANCES. INTO THE WEEKEND. FIRE WEATHER... ELEVATED TO CRITICAL FIRE WEATHER CONDITIONS WILL BE POSSIBLE SUNDAY AFTERNOON ACROSS THE NORTHWESTERN TEXAS PANHANDLE AND WESTERN OKLAHOMA PANHANDLE. THE DRYLINE WILL MOVE INTO THE PANHANDLES AND DROP RELATIVE HUMIDITIES FOR THIS AREA BELOW 15 PERCENT WHILE 20 FOOT WINDS FROM THE SOUTHWEST INCREASE TO 15 TO 20 MPH. GIVEN THE LOW FUEL LOADS DUE TO THE ONGOING DROUGHT...THE PRECIP LAST NIGHT IN THIS AREA...AND THE POTENTIAL FOR PRECIP TONIGHT HAS LEAD TO SOME CONCERN WHERE A FIRE WEATHER PRODUCT WILL BE NEEDED DUE TO THE GOOD STATE OF FUELS. WITH THAT SAID IF PRECIP DOES NOT OCCUR TONIGHT THEN A FIRE WEATHER WATCH OR RED FLAG WARNING MAY BE NEEDED FOR THIS TIME FRAME. ELEVATED TO NEAR CRITICAL FIRE WEATHER WILL BE POSSIBLE MONDAY FOR THE WESTERN HALF OF THE TEXAS AND OKLAHOMA PANHANDLE WITH RELATIVE HUMIDITIES AGAIN DROPPING BELOW 15 PERCENT AS 20 FOOT WINDS INCREASE TO 15 TO 20 MPH. ELEVATED FIRE WEATHER MAY BE POSSIBLE AGAIN ON TUESDAY AS RELATIVE HUMIDITIES DROP BETWEEN 15 AND 20 PERCENT WITH 15 TO 20 MPH 20 FOOT WINDS. THE ONLY CONCERN FOR THE FIRE POTENTIAL FOR TUESDAY WILL BE THE POSSIBILITY FOR SHOWERS TO DEVELOP FURTHER WEST THAN CURRENTLY FORECAST. && .AMA WATCHES/WARNINGS/ADVISORIES... TX...NONE.
