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 Goodland, KS wrote its last area forecast discussion before this tornado warning went out at Jun 10, 5:16 PM MDT, 3 hours 39 minutes earlier.

Area forecast discussion, Jun 10, 5:16 PM MDT, 3 hours 39 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GOODLAND KS
516 PM MDT THU JUN 10 2010

.DISCUSSION...
245 PM MDT THU JUN 10 2010

A PLETHORA OF FORECAST CHALLENGES EXIST DURING THIS SEVEN DAY
PERIOD...NOT THE LEAST OF WHICH ARE SEVERE POTENTIAL TONIGHT IN
THE NORTH AND TEMPS OVER THE WEEKEND.

IN THE NEAR TERM FOR TONIGHT...THE BIGGEST QUESTION IS THE FUTURE
AREAL EXTENT OF CONVECTION NOW FORMING ON THE HIGHER TERRAIN OF
NORTHERN COLORADO INTO SOUTHEAST WYOMING. THE NAM SEEMS TO HAVE A
DECENT HANDLE ON CONVECTION BASED ON LATEST RADAR AND SATELLITE
TRENDS...BRINGING STORMS INTO THE PLAINS OF NE COLORADO WHICH THEN
RIDE ALONG THE NORTHERN PERIPHERY OF THE WARM TEMPS AT 700 MB
OVERNIGHT. BASED ON THIS SCENARIO HAVE THE HIGHEST POPS IN THE
NORTHERN TIER OF COUNTIES BETWEEN 00Z AND 06Z. ANY STORMS WHICH
DEVELOP IN THIS AREA WILL LIE IN AN AREA OF DECENT 6 KM SHEAR OF
50 KTS AND WILL BE TAPPING INTO FAVORABLE LOW LEVEL MOISTURE...SO
ORGANIZED SEVERE CONVECTION SEEMS LIKELY. CURRENT THINKING IS
STRONG CAP WILL HOLD FOR NOW AND WE WILL NEED TO WAIT FOR STORMS
CURRENTLY MOVING OFF HIGHER TERRAIN OF COLORADO TO MOVE IN THIS
EVENING.

HAVE ALSO INCLUDED SLIGHT CHANCE POPS FOR MUCH OF REMAINDER OF
CWA OVERNIGHT BASED ON THE NAMS PERSISTENT FORECAST OF ISOLATED
CONVECTION WHICH ORIGINATES IN SOUTHEAST COLORADO THIS AFTERNOON.
ISOLATED CELLS HAVE BEEN STRUGGLING DOWN THERE FOR AN HOUR OR TWO
AND SOME COULD SURVIVE AS THEY MOVE NORTHEAST. AT THIS TIME IT
LOOKS MAINLY LIKE GUSTY WINDS FROM THESE STORMS. SPOTTY ACCAS AND
VIRGA CURRENTLY APPEAR SOUTH AND SOUTHEAST OF GOODLAND.

LATEST SURFACE ANALYSIS PUTS A SURFACE LOW ALONG THE KS-CO BORDER
SOUTHWEST OF TRIBUNE KANSAS NEAR LAMAR COLORADO. SOUTHWEST FROM
THIS LOW IS THE REMAINS OF THE OUTFLOW BOUNDARY FROM LAST NIGHTS
NEBRASKA MCS WHICH STRETCHES BACK TO THE FRONT RANGE SOUTH OF
PUB. A DRY PUSH IS SEEN NUDGING INTO WESTERN KANSAS SOUTH OF THE
LOW WHERE DEWPOINTS DROP FROM THE LOW 60S TO THE MID 40S. SURFACE
CONVERGENCE ALONG THIS FEATURE DOES NOT APPEAR THAT IMPRESSIVE
RIGHT NOW...AND THIS AREA IS SITTING BENEATH PROGGED 700 MB TEMPS
OF 16 C. OVER KANSAS THE MORNING OUTFLOW BOUNDARY IS GETTING
DIFFICULT TO FIND IN THE SURFACE DATA BUT BEST ESTIMATES WOULD
PLACE IT AS A WARM FRONT RETURNING NORTH ALONG A TRIBUNE TO OAKLEY
TO PHILLIPSBURG LINE.

OVER THE WEEKEND THE BIG PICTURE IS A LARGE SLOW MOVING UPPER LOW
LUMBERING EAST ACROSS THE MOUNTAINS WITH NUMEROUS IMPULSES LIFTING
NORTHEAST ACROSS THE AREA. ALL GUIDANCE SUGGESTS THAT A SURFACE
FRONT WILL PUSH SOUTHEAST THROUGH THE AREA SATURDAY. GUIDANCE
THEN KEEPS THIS SURFACE FEATURE SOUTH OF THE CWA SUNDAY AND
MONDAY WHICH SHOULD TRANSLATE INTO A COOLER CLOUDY PERIOD WITH
EPISODES OF SHOWERS AND THUNDERSTORMS. THE NAM SEEMS A BIT
AGGRESSIVE WITH COOLING 850 TEMPS DOWN TO 8 C...BUT NONETHELESS...
HIGH TEMPS WILL BE ONLY IN THE 60S MOST AREAS ON SUNDAY.

NOT MANY BIG CHANGES MADE TO THE EXTENDED. THE UPPER LOW AFFECTING
THE AREA THROUGH SUNDAY WILL FINALLY LIFT NORTHEAST BY MONDAY
EVENING FOLLOWED BY BROAD UPPER RIDGING. THIS PATTERN IS REFLECTED
IN MUCH LOWER POPS FOR THE TUE-THU PERIOD ALONG WITH GRADUALLY
WARMING TEMPERATURES.

.AVIATION...
514 PM MDT THU JUN 10 2010

FOR THE 00Z TAF CYCLE...PRIMARY AVIATION CONCERNS THIS PERIOD ARE POTENTIAL
FOR THUNDERSTORM ACTIVITY THIS EVENING FOLLOWED BY LOW STRATUS POSSIBILITY
OVERNIGHT. AT THIS TIME IT APPEARS THAT MAJORITY OF TSRA WILL BE TO
THE NORTH AND WEST OF THE TERMINALS BUT A DIRECT IMPACT IS CERTAINLY
POSSIBLE. SHOULD CONVECTION PASS NEAR OR OVER A TERMINAL INTERMITTENT
MVFR/IFR CONDITIONS WILL BE LIKELY. CANNOT PIN DOWN TIMING YET THUS
WILL INDICATE TSRA POTENTIAL WITH CB GROUPS FOR NOW AND AMEND AS NECESSARY.
BETWEEN ROUGHLY 09Z-12Z ALSO EXPECT AT LEAST MVFR POST-FRONTAL
CIGS...WITH IFR CIGS A POSSIBILITY AS WELL. THUNDERSTORMS WILL
AGAIN BE POSSIBLE TOMORROW AFTERNOON AND EVENING AT BOTH SITES.
