What forecasters said that day
The local office's own words before this tornado warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Amarillo, TX wrote its last area forecast discussion before this tornado warning went out at Apr 22, 12:28 PM CDT, 4 hours 41 minutes earlier.
Area forecast discussion, Apr 22, 12:28 PM CDT, 4 hours 41 minutes before
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE AMARILLO TX 1228 PM CDT THU APR 22 2010 .AVIATION... DRYLINE SLOWER TO FORM BUT IS EXPECTED TO SHARPEN QUICKLY EARLY THIS AFTERNOON. DRYLINE SHOULD BE ORIENTED FROM ABOUT GUYMON TO AMARILLO BY 19-20Z. DUE TO THE CLOSE PROXIMITY...DECIDED TO MENTION TSRA AT KAMA AND KGUY TAFS. KDHT DRY. DRY ALL TAF SITES FRIDAY BUT WINDS EXPECTED TO INCREASE TO GUSTS OF 30-35KT && .PREV DISCUSSION... /ISSUED 705 AM CDT THU APR 22 2010/ AVIATION... CONVECTION WILL BE THE MAIN AVIATION CONCERN TODAY. MORNING SHOWERS WILL CONTINUE TO IMPACT DHT FOR THE NEXT HOUR OR TWO...WITH LESSER CHANCES AT GUY/AMA. LATEST GUIDANCE STILL SUGGESTING A DRYLINE SETTING UP ACROSS THE PANHANDLES TODAY. WILL KEEP CB REMARKS ATTM FOR AMA/GUY TO ACCOUNT FOR POSSIBLE CONVECTION THAT DEVELOPS AS OPPOSED TO PREVAILING OR TEMPO THUNDERSTORM REMARKS. WILL KEEP THE FORECAST VFR FOR NOW BUT PERIODIC MVFR/IFR CIGS/VSBYS WILL BE POSSIBLE IN AND NEAR THUNDERSTORMS. TAB PREV DISCUSSION... /ISSUED 329 AM CDT THU APR 22 2010/ DISCUSSION... THE QUASI STATIONARY FRONT THAT STALLED OVER THE SOUTHERN TX PANHANDLE YESTERDAY AFTERNOON HAS BEEN MOVING NORTH AS A WARM FRONT THIS MORNING AND IS NEAR THE OK PANHANDLE AT THIS TIME. FARTHER SOUTH... A CLUSTER OF SHOWERS AND THUNDERSTORMS THAT DEVELOPED IN THE EASTERN PLAINS OF NM HAS MAINTAINED INTENSITY WITH THE INTENSIFYING LOW LEVEL JET AS IT MOVES INTO THE SOUTH CENTRAL TX PANHANDLE. THIS CONVECTION WILL CONTINUE TO SLOW TREK TO THE EAST THIS MORNING WITH A SMALL POTENTIAL FOR MARGINALLY SEVERE HAIL. THE MAIN SHOW IS ANTICIPATED FOR THIS AFTERNOON AND EVENING. A DRYLINE IS FORECAST TO DEVELOP IN THE WARM SECTOR WITH SUBSTANTIAL SHEAR AVAILABLE. WITH RECENT RAINFALL AND OUR INABILITY TO BREAK OUT OF THE GRUNGE OVER THE PAST FEW DAYS...THE FORECAST AFTERNOON DRYLINE POSITION IS STILL QUESTIONABLE. AFTER COORDINATION WITH NEIGHBORING OFFICES...WE DECIDED TO GO WITH A MORE DIFFUSE EAST-WEST POP GRADIENT IN CASE THE DRYLINE IS UNABLE TO MIX TO THE EDGE OF THE CAPROCK. WITH THE EXPECTED DIABATIC HEATING...CAPE VALUES SHOULD REACH 1500 TO 2000 J/KG ON THE MOIST SIDE OF THE BOUNDARY...COINCIDENT WITH THE UPPER 50S TO LOWER 60S DEWPOINTS. WE WILL STILL CARRY THE MENTION OF LARGE HAIL...DAMAGING WINDS AND ISOLATED TORNADOES IN THE HWO AND SEVERE THUNDERSTORMS IN THE PUBLIC FORECAST FROM 18Z TO 06Z. THE MAIN CAVEAT IS THE WEAKLY CAPPED ENVIRONMENT THAT MAY LEND TOWARD EARLIER CONVECTIVE INITIATION AND NON DISCRETE CELLS...RESULTING IN A LARGE MASS OF CONVECTION WITH LOWER SEVERE POTENTIAL. WE COULD ALSO SEE SOME MODIFICATION OF OUR CURRENT STEEP MID LEVEL LAPSE RATES DUE TO THE CURRENT CONVECTION. THE AFTERNOON CONVECTION IS FORECAST TO GROW UPSCALE INTO A LARGE MCS...EVENTUALLY MOVING OUT OF THE PANHANDLES BEFORE 12Z FRIDAY AS A PACIFIC COLD FRONT USHERS DRIER AIR INTO THE CWA. THIS WILL RESULT IN SLIGHTLY COOLER BUT DRY/BREEZY CONDITIONS ON FRIDAY. THE UPPER LOW IS PROGGED TO LIFT NORTHEAST ACROSS THE SOUTHERN/CENTRAL HIGH PLAINS FRIDAY NIGHT AND MAY PROVIDE ENOUGH LIFT TO CREATE SOME LIGHT SHOWERY ACTIVITY ACROSS THE NORTHERN ZONES. A COLD FRONT WILL BLOW THROUGH THE AREA EARLY SATURDAY ON THE BACKSIDE OF THIS UPPER CYCLONE...BRINGING BRISK NORTH TO NORTHWEST WINDS TO THE AREA. AGAIN...SOME LIGHT PRECIP WILL BE POSSIBLE IN THE NORTH BUT SHOULD NOT AMOUNT TO MUCH. WE SHOULD MAINTAIN SLIGHTLY BELOW TEMPS ON SUNDAY AS A GENERAL UPSLOPE FLOW ON THE SOUTH SIDE OF THE SURFACE ANTICYCLONE. THERE IS AN OUTSIDE CHANCE THAT WE COULD SEE SOME CONVECTION OVER THE NORTHWEST ZONES. THE UPSLOPE FLOW SHOULD CONTRIBUTE TO DIURNAL TSTORMS OVER THE HIGHER TERRAIN OF NM/CO AND THE NORTHWEST FLOW ALOFT COULD USER A FEW INTO THE AREA. THIS CHANCE IS REMOTE SO NO MENTION WILL BE MADE AT THIS TIME. THE MEDIUM RANGE MODELS CONTINUE TO SHOW DECENT SYNOPTIC SCALE AGREEMENT FOR THE EARLY PART OF NEXT WEEK BUT DIFFER ON THE SMALLER FEATURES. THE ECMWF CONTINUES TO DRIVE A STRONGER COLD FRONT INTO THE AREA LATE MONDAY ALTHOUGH THE LAST CYCLE OF THE GFS IS TRENDING COOLER...WHICH LOOKS BETTER AT THE MOMENT. I TOYED WITH THE IDEA OF INSERTING LOW POPS MONDAY NIGHT AND TUESDAY BUT HELD OFF FOR ONE MORE DAY TO SEE IF THE MODELS CAN MAINTAIN THIS SOLUTION. LEE CYCLOGENESIS IS ANTICIPATED BY MID WEEK AS ANOTHER TROF DIGS INTO THE SOUTHWEST CONUS AND PROVIDES INCREASING SOUTHWEST FLOW ALOFT FOR THE HIGH PLAINS. THIS WILL RESULT IN A WARM UP INTO THE MID 70S BY WEDNESDAY. JOHNSON FIRE WEATHER... FIRE WEATHER CONCERNS WILL GENERALLY BE LIMITED THROUGH THE NEXT 7 DAYS OWING TO RESIDUAL GROUND MOISTURE FROM RECENT RAINFALL. WINDS WILL INCREASE TODAY TO AROUND 20 MPH WITH RELATIVE HUMIDITIES FALLING TO AROUND 25 PERCENT. ON FRIDAY...SOUTHWEST WINDS OF 15 TO 20 MPH ARE EXPECTED WITH RELATIVE HUMIDITIES AROUND 20 PERCENT. ADDITIONAL WINDY CONDITIONS ARE ANTICIPATED ON SATURDAY IN THE WAKE OF A COLD FRONT BUT HUMIDITIES WILL NOT BE AS LOW. JOHNSON && .AMA WATCHES/WARNINGS/ADVISORIES... TX...NONE. OK...NONE. && 07/02
