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 30, 6:23 PM CDT, 1 hour 45 minutes earlier.

Area forecast discussion, Jun 30, 6:23 PM CDT, 1 hour 45 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GOODLAND KS
523 PM MDT SAT JUN 30 2012

.UPDATE...
ISSUED AT 510 PM MDT SAT JUN 30 2012

MADE MINOR TWEEKS TO THE FORECAST FOR THIS EVENING DUE TO THE LINE
OF STORMS PROGRESSING EAST FASTER THAN ANTICIPATED. DURING THE
LATE EVENING THE HIGHER PRECIP. CHANCES SHIFT BACK WEST AS ANOTHER
UPPER LEVEL SHORT WAVE TROUGH MOVES INTO THE AREA. STORM ACTIVITY
STILL LOOKS TO DISSIPATE AFTER MIDNIGHT.

ALSO UPDATED THE WIND FORECAST. AHEAD OF THE STORMS WINDS ARE FROM
THE EAST. ONCE THE STORMS MOVE THROUGH WINDS BECOME ERRATIC WITH
GUSTS UP TO 40 OR 50 MPH. WINDS SLOWLY DECLINE BEHIND THE
STORMS...ALTHOUGH THE VARIOUS OUTFLOW BOUNDARIES MAKE PICKING A
DIRECTION TRICKY BUT WINDS SHOULD GENERALLY COME AROUND TO THE SOUTH.

&&

.SHORT TERM...(THIS EVENING THROUGH SUNDAY)
ISSUED AT 202 PM MDT SAT JUN 30 2012

NEXT IN A SERIES OF SHORTWAVE TROUGHS IS ALREADY MOVING INTO
NORTHERN CO...WITH MODERATELY UNSTABLE AIR MASS IN PLACE ACROSS
CWA. INITIAL IMPRESSIONS WERE THAT STABLE AIR BEHIND FIRST
EXITING SHORTWAVE WOULD BE ENOUGH TO LIMIT THUNDERSTORM INITIATION
UNTIL 00Z...HOWEVER HIGH BASE SHOWERS AND THUNDERSTORMS HAVE
ALREADY DEVELOPED ALONG CONVERGENCE ZONE ALONG EASTERN EXTENT OF
SURFACE TROUGH. AS SHORTWAVE TROUGH OVER NORTHERN COLORADO MOVES
EAST THIS ACTIVITY SHOULD INCREASE IN COVERAGE THROUGH LATE
AFTERNOON/EARLY EVENING. LLJ DEVELOPS AROUND 00Z...AND WILL HELP
SUPPORT SHEER PROFILES FAVORABLE FOR HIGH WIND/HAIL THREAT THIS
AFTERNOON AND EVENING.

ANY THUNDERSTORM ACTIVITY SHOULD END BY AROUND 09Z AS SHORTWAVE
MOVES EAST. NEXT WEAK SHORTWAVE IS EXPECTED TO ARRIVE LATE
AFTERNOON/EARLY EVENING ON SUNDAY AND COULD BRING ISOLATED
THUNDERSTORM CHANCES TO THE AREA...POSSIBLY A REPEAT OF TONIGHT
WITH HIGH BASED SHOWERS/THUNDERSTORMS. I KEPT COVERAGE LIMITED TO
ISOLATED DURING THE AFTERNOON PERIOD WITH TIMING OF INITIATION
STILL FAVORED IN THE EVENING.

.LONG TERM...(SUNDAY NIGHT THROUGH SATURDAY)
ISSUED AT 203 PM MDT SAT JUN 30 2012

DO NOT SEE MUCH CHANGE DURING THIS PERIOD. A LARGE SPRAWLING UPPER
LEVEL RIDGE WILL DOMINATE THE CONUS WEATHER EAST OF THE ROCKIES.
THE LOCAL FORECAST AREA WILL BE CLOSE ENOUGH TO THE WESTERN FRINGE
OF THE ANTICYCLONIC CIRCULATION TO OPEN THE DOOR FOR SHORTWAVE
TROUGHS MOVING ACROSS THE ROCKIES AND ALMOST DAILY CHANCES FOR
THUNDERSTORMS...BEST CHANCES BEING IN EASTERN COLORADO...IN THE
LATE AFTERNOON AND EVENING HOURS. HIGH TEMPERATURES WILL GENERALLY
BE IN THE 100-105 RANGE WITH LOW TEMPERATURES IN THE UPPER 60S TO
MIDDLE 70S.

&&

.AVIATION...(FOR THE 00Z TAFS THROUGH 00Z SUNDAY EVENING)
ISSUED AT 510 PM MDT SAT JUN 30 2012

VFR CONDITIONS ARE FORECAST FOR THE 0Z TAFS. THUNDERSTORMS
CURRENTLY OVER THE TAF SITES SHOULD MOVE EAST OF THE SITES BY 0Z.
AFTER THAT HAVE VCTS THROUGH THE EVENING INTO THE OVERNIGHT HOURS.
DID NOT INSERT A TEMPO GROUP FOR TS DURING THE EVENING SINCE
STORMS WILL LIKELY BE TOO SPOTTY TO TIME IN TO EITHER SITE. WILL
MONITOR THROUGH THE EVENING INCASE A TEMPO GROUP IS NEEDED. IF
STORMS DO MOVE OVER THE SITES WINDS MAY GUST UP TO 35KTS OR SO.
DURING THE OVERNIGHT HOURS THE INSTABILITY AND LIFT BEGIN TO WANE
BRINGING STORM ACTIVITY TO AN END. SUNDAY AFTERNOON THUNDERSTORMS
MAY AGAIN DEVELOP ACROSS THE TRI-STATE AREA. WILL HOLD OFF
INSERTING ANY MENTION WITH THESE TAFS DUE TO THE ISOLATED NATURE.
