What forecasters said that day

The local office's own words before this severe thunderstorm 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 severe thunderstorm warning went out at Jun 22, 11:46 AM CDT, 3 hours 44 minutes earlier.

Area forecast discussion, Jun 22, 11:46 AM CDT, 3 hours 44 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE AMARILLO TX
1146 AM CDT SUN JUN 22 2014

.AVIATION...
SEVERAL FACTORS COULD IMPACT EACH TERMINAL OVER THE NEXT 24 HOURS.
THE FIRST WILL BE CONVECTION THIS AFTERNOON AND TONIGHT. KGUY HAS
THE BEST CHANCE TO BE IMPACTED AND HAVE INSERTED SHRA AFTER 02Z.
CHANCES ARE A LITTLE LOWER FOR KAMA AND KDHT...SO HAVE KEPT MENTION
OF VICINITY THUNDER. SHOULD A THUNDERSTORM MOVE OVER A TERMINAL THEN
BRIEF MVFR/IFR CONDITIONS WILL BE POSSIBLE. THE NEXT FACTOR WILL BE
A COLD FRONT MOVING THROUGH THE PANHANDLES LATE TONIGHT. THIS FRONT
WILL TRANSITION WINDS FROM THE SOUTHWEST TO A NORTHERLY DIRECTION.
THE FINAL FACTOR WILL BE THE POTENTIAL FOR LOW CLOUDS TOMORROW
MORNING. HAVE LOWERED CEILINGS TO MVFR TOMORROW MORNING BUT IFR IS
NOT OUT OF THE QUESTION ESPECIALLY FOR KGUY.

&&

PREV DISCUSSION... /ISSUED 515 AM CDT SUN JUN 22 2014/

DISCUSSION...
BY AND LARGE...THE FORECAST REMAINS CLOSE TO PREVIOUS THINKING ON
CONVECTIVE ACTIVITY OVER THE NEXT SEVERAL DAYS. THE FOCUS REMAINS ON
THE POTENTIAL FOR HEAVY RAIN/POSSIBLE SEVERE THUNDERSTORMS THIS
EVENING AND TONIGHT ASSOCIATED WITH AN ADVANCING COLD FRONT.
THUNDERSTORM CHANCES LINGER THROUGH WEDNESDAY AS MOIST AIR REMAINS
IN THE REGION...AND THEN A MOSTLY DRY FORECAST WRAPS UP THE SECOND
HALF OF THIS WEEK.

TODAY AND TONIGHT...
ALL MODEL GUIDANCE AGREES ON CONVECTIVE ACTIVITY INITIATING ACROSS
SOUTHERN CO/KS THIS AFTERNOON AND THEN CONGEALING INTO AN MCS BY THE
EVENING. AT THE SAME TIME...A COLD FRONT WILL BE DIVING SOUTHWARD
THROUGH THE HIGH PLAINS. REINFORCED BY OUTFLOW FROM THE MCS TO OUR
NORTH...THE COLD FRONT SHOULD REACH THE OK PANHANDLE BY 00-03Z AND
OUR SOUTHERN COUNTIES BY 12Z MONDAY. THE VARIOUS MODELS DISAGREE ON
THE EXTENT OF THUNDERSTORM DEVELOPMENT ALONG THE FRONT...BUT THE
GREATEST CHANCES FOR PRECIPITATION WILL BE THE NORTHEASTERN HALF OF
THE CWA DUE TO PROXIMITY TO THE FRONT AND THE CO/KS MCS. ISOLATED TO
SCATTERED TSTMS ARE POSSIBLE LATE THIS AFTERNOON AHEAD OF THE
FRONT...MAINLY ACROSS THE OK PANHANDLE AND NORTHERN TX
PANHANDLE...WHERE DAYTIME HEATING AND LIFT AHEAD OF THE SHORTWAVE
COULD BREAK THE CAP AND TAP INTO 2000 J/KG OF CAPE AND NEAR 40KTS OF
0-6KM SHEAR. LARGE HAIL WOULD BE THE PRIMARY THREAT WITH THESE
STORMS. THE THREAT TRANSITIONS TO PRIMARILY A HIGH WIND/HEAVY RAIN
SCENARIO AS THE FRONT/MCS OUTFLOW PUSHES SOUTH OVERNIGHT. MOIST
FORECAST SOUNDINGS...ELEVATED INSTABILITY ON THE ORDER OF 2000 J/KG
OF CAPE...PROJECTED PWAT VALUES OF 1.0-1.3 INCHES...AND A
STRENGTHENING LOW LEVEL JET AIMED STRAIGHT AT THE FRONT SUGGEST VERY
HEAVY RAINFALL CAN BE EXPECTED.

AFTER TONIGHT...IT APPEARS THAT SEVERAL PERIODS OF RAIN MAY BE
POSSIBLE ACROSS THE PANHANDLES THROUGH WEDNESDAY...THOUGH MUCH OF
THIS DEPENDS ULTIMATELY ON HOW TODAY'S MCS EVOLVES. THE FRONT IS
EXPECTED TO LINGER ACROSS THE AREA...WITH IT POSSIBLY FOCUSING TSTM
CHANCES FURTHER SOUTH OF US TOMORROW. SOUTHERLY SURFACE FLOW
ESTABLISHES ITSELF AGAIN BY TUESDAY...WITH ANOTHER SHORTWAVE IN THE
UPPER-LEVEL FLOW LIKELY TO TRIGGER STORMS OVER THE ROCKIES. NEXT
GREATEST CHANCE FOR RAINFALL WILL BE TUESDAY NIGHT AS TSTMS ROLL OUT
OF THE MOUNTAINS AND ENCOUNTER A DEVELOPING LLJ.

WITH THE AMOUNT OF UNCERTAINTY IN WHAT THE ATMOSPHERE WILL HAVE LEFT
TO GIVE AFTER THE NEXT FEW DAYS...ONLY SLIGHT CHANCE POPS WEDNESDAY
AND THEN A DRY FORECAST UNTIL SATURDAY. ADDING TO THE
UNCERTAINTY...THE GFS AND ECMWF CONTINUE TO STRUGGLE WITH THE UPPER
AIR PATTERN AFTER MIDWEEK. A DEEPENING TROUGH OVER THE WESTERN CONUS
IS NOW THE CONSENSUS...THOUGH THE GFS DISPLACES A STRONGER ZONAL FLOW
OVER THE DESERT SOUTHWEST WHILE THE ECMWF PINCHES PINCHES OFF THE
FLOW BY NEXT WEEKEND AND THE JET STREAM STAYS FURTHER NORTH. THE MORE
DYNAMIC SOLUTION OF THE GFS SPELLS WINDIER...HOTTER...AND DRIER FOR
THE PANHANDLES.

NF

FIRE WEATHER...
THERE ARE NO FIRE WEATHER CONCERNS FOR THE TEXAS AND OKLAHOMA
PANHANDLES THIS WEEK DUE TO HIGHER FUEL MOISTURE CONTENT AND EXPECTED
HEAVY RAINS.

NF

HYDROLOGY...
LOCALLY HEAVY RAINFALL WITH THUNDERSTORMS TONIGHT AND AGAIN ON
TUESDAY NIGHT WILL LEAD TO THE POTENTIAL FOR FLASH FLOODING ACROSS
MAINLY THE EASTERN HALF OF THE TEXAS AND OKLAHOMA PANHANDLES.
