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 Goodland, KS wrote its last area forecast discussion before this severe thunderstorm warning went out at Jun 13, 4:44 PM MDT, 37 minutes earlier.

Area forecast discussion, Jun 13, 4:44 PM MDT, 37 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GOODLAND KS
444 PM MDT MON JUN 13 2011

.DISCUSSION...
325 PM MDT MON JUN 13 2011

FORECAST PROBLEM WILL BE CONTINUED CHANCES FOR PRECIPITATION THROUGH
THE ENTIRE PERIOD. SATELLITE CONTINUING TO SHOW AN ACTIVE AND
PROGRESSIVE FLOW PATTERN FROM THE CENTRAL PACIFIC INTO THE WESTERN
ATLANTIC. NUMEROUS SHORTWAVE TROUGHS EMBEDDED WITHIN THIS FLOW.
PERSISTENT STATIONARY BOUNDARY STILL REMAINS TO OUR SOUTH AND WEST.

MODELS INITIALIZED WELL AT MID AND UPPER LEVELS. MODELS WERE NOT
QUITE FAR ENOUGH SOUTH WITH THE FRONT. THE ECMWF WAS DOING SLIGHTLY
BETTER THAN THE NAM. MODELS WERE HAVING TROUBLES WITH THE LOW
LEVEL THERMAL FIELD. THE ECMWF AND GFS WERE DOING BETTER THAN
EVERYONE ELSE.

TONIGHT...SATELLITE/PV ANALYSIS SHOWS DECENT SHORTWAVE TROUGH OVER
THE SOUTHERN GREAT BASIN MOVING TOWARD THE AREA. LEFT FRONT QUADRANT
OF SOUTHERN JET GRADUALLY GETS CLOSER TO THE AREA THROUGH THE NIGHT
WITH THE UKMET/NAM THE LEAST FAVORABLE OF THE BUNCH. FRONTAL BOUNDARY
IS FURTHER SOUTH THAN MODELS WERE INDICATING YESTERDAY. THEREFORE
ANY LOW LEVEL FOCUS IS MUCH FURTHER SOUTH TODAY THAN INDICATED
YESTERDAY. ALTHOUGH WE ARE VERY MOIST AND UNSTABLE AT THIS TIME...
AREA IS VERY CAPPED TO SURFACE BASED CONVECTION AS WELL.

AIR MASS REMAINS MOIST AND UNSTABLE THROUGH THE NIGHT. LIFT
INCREASES THROUGH THE NIGHT AND INHIBITION DECREASES BY LATE
TONIGHT...MAINLY IN THE NORTHWEST. IT LOOKS TO BE ONE OF THOSE RARE
INSTANCES WHERE PRECIPITATION WILL OCCUR LATE IN THE NIGHT. GREATEST
CHANCE WILL BE IN THE NORTHWEST.

TUESDAY/TUESDAY NIGHT...LIFT...MOISTURE AND INSTABILITY MOVE ACROSS
IN THE MORNING. THAT WILL BE WHEN THE GREATEST CHANCE OF
PRECIPITATION WITH ONLY A SLIGHT CHANCE IN THE AFTERNOON.
COMBINATION OF CLOUDS...PRECIPITATION...AND UPSLOPE WINDS WILL KEEP
TEMPERATURES COOLER. WILL TREND TOWARD THE COOLER GUIDANCE.

LEFT FRONT QUADRANT OF THE JET AND SOME LINGERING MID LEVEL LIFT AND
INSTABILITY WILL BE NEAR OR OVER THE SOUTHWEST PORTION OF THE
FORECAST AREA. WILL KEEP A SLIGHT CHANCE MENTION THERE DURING THE
EVENING.

WEDNESDAY/WEDNESDAY NIGHT...LITTLE TO NO LIFT DURING THE DAY
WITH AN UNCAPPED AIR MASS IN PLACE. WILL KEEP IT DRY DURING THE DAY.
LIFT INCREASES DURING THE NIGHT ALONG WITH ADEQUATE MOISTURE SO
INSERTED A SLIGHT CHANCE BUT CONFIDENCE IS LOW. WILL AGAIN TREND
TOWARD THE COOLER GUIDANCE SINCE SURFACE HIGH IS JUST BEGINNING TO
PULL AWAY.

THURSDAY/THURSDAY NIGHT...AIR MASS REMAINS CAPPED THROUGH THE DAY SO
KEPT IT DRY. LATEST MODEL OUTPUT SUPPORTS THE SLIGHT CHANCE IN THE
NORTHEAST HALF SO DID NOT CHANGE. DID WARM UP MAXES A FEW DEGREES
BUT POTENTIAL IS THERE FOR THESE TO BE TOO WARM.

FRIDAY THROUGH MONDAY...MODELS IN MUCH CLOSER AGREEMENT THAN THEY
HAVE BEEN THE PREVIOUS FEW DAYS. ECMWF DOES REMAIN SLIGHTLY DEEPER
THAN THE GFS. DO LIKE WHAT THEY ARE SHOWING. AGAIN MODELS TRY OR DO
BRING A SHORTWAVE TROUGH ALMOST EVERY SINGLE PERIOD. MODELS HAVING
TROUBLE IN THE SHORT TERM IN RESOLVING SHORTWAVE DETAILS SO TO TRY
TO RESOLVE FURTHER OUT IS PROBLEMATIC. OVERALL MODEL
SOLUTIONS/DETAILS DID NOT CHANGE TOO MUCH FROM THE PREVIOUS 24
HOURS. SO BECAUSE OF THAT AND UNCERTAINTY DID NOT CHANGE MUCH.
HOWEVER...DESPITE THE SIMILAR SOLUTIONS ALOFT...MODELS ARE ALL OVER
THE PLACE IN WHERE THEY PUT THE FRONTAL BOUNDARY THAT IS NEAR OUR
AREA.

SO DEPENDING ON WHICH SOLUTION YOU BUY...IT COULD BE VERY HOT OR
MUCH COOLER. BASED ON RECENT TRENDS AND EXPERIENCE IN THIS PATTERN...
AM BELIEVING THAT A LITTLE COOLER SOLUTION WILL END UP BEING MORE
CORRECT. THE OPERATIONAL MEX HAS BEEN THE WARMEST MEMBER WITH THE
ENSEMBLES SUPPORTING COOLER CONDITIONS. TENDED TO GO THAT WAY BUT WHO
KNOWS AT THIS POINT. KEPT THE PRECIPITATION IN THE FORECAST THROUGH
SATURDAY. MADE SUNDAY INTO MONDAY DRY DUE TO A VERY DRY WESTERLY
FLOW ALOFT.

THANKS TO ALL WHO COLLABORATED.

.AVIATION...
444 PM MDT MON JUN 13 2011

FOR THE 00Z TAFS...SLIGHT CHANCE FOR THUNDERSTORMS AT THE TERMINALS
THIS EVENING...BUT GIVEN THE CAP ALOFT...POSITION OF FRONT...AND
CURRENT STORM MOVEMENT...EXPECTING THE STORMS TO REMAIN WEST OF THE
TERMINALS. CONDITIONS SHOULD DROP INTO THE LIFR RANGE OVERNIGHT WITH
LOW LEVEL MOISTURE AND LIGHT WINDS...AND MODEL SOUNDINGS ARE IN
AGREEMENT WITH CONDITIONS DECREASING AFTER 06Z. KGLD WILL IMPROVE
BEFORE KMCK IN THE MORNING AS WINDS AND MIXING INCREASE...AND DRIER
AIR IS MOVED TOWARD THE TERMINAL.
