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 Cheyenne, WY wrote its last area forecast discussion before this severe thunderstorm warning went out at Jun 22, 1:30 PM MDT, 5 hours 9 minutes earlier.

Area forecast discussion, Jun 22, 1:30 PM MDT, 5 hours 9 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
130 PM MDT SUN JUN 22 2008

.SHORT TERM...TONIGHT THROUGH TUESDAY...
UPPER SHORTWAVE EVIDENT IN SAT PICS FROM CENTRAL MONTANA INTO
CENTRAL WY AND COLORADO WILL CONTINUE TO MOVE EAST THROUGH TONIGHT
WITH ISOLD/SCT TSTRMS ASSOCIATED WITH IT.  BEST CHANCE FOR TSTRMS
THIS EVENING LOOKS TO BE FROM EAST CENT WY INTO THE PANHANDLE WHERE
BETTER MOISTURE AND INSTABILITY WILL EXIST.  ACTIVITY SHOULD BE CLEAR
OF CWA BY LATE THIS EVENING AS SHORTWAVE MOVES BY.  FOR MONDAY AND
TUESDAY SEE LITTLE CHANGES AS UPPER RIDGING PERSISTS OVER THE ROCKY
MTNS WITH WEAK IMPULSES MOVING THRU THIS RIDGE.  CONVECTION MAY BE
AIDED EAST OF THE MTNS MONDAY AFTERNOON AND EVENING AS A MODEST PUSH
OF COOLER AIR TRIES TO SINK INTO THE REGION BEHIND A LITTLE STRONGER
UPPER TROF TRAVERSING ACROSS THE FAR NRN PLAINS. TUESDAY LOOKS TO BE
WARMER WITH SOMEWHAT LESS COVERAGE OF CONVECTION AS UPPER RIDGE
STRENGTHENS A BIT.

.LONG TERM...TUESDAY NIGHT THROUGH SUNDAY.
THE MEDIUM RANGE FORECAST MODELS ARE INDICATING A SLIGHTLY LESS
AMPLIFIED UPPER LEVEL FLOW PATTERN DURING THE EXTENDED FORECAST
PERIOD. THE FLOW ALOFT ENDS UP BEING NEARLY ZONAL MIDWEEK WITH THE
MAIN FEATURES BEING A LOW OVER THE ALEUTIANS AND ANOTHER TROUGH
OVER NORTHERN NEW ENGLAND AND THE MARITIME PROVINCES OF CANADA. A
WEAKENING UPPER LOW WILL EJECT ONTO THE WESTERN CANADIAN COAST
FROM THE GULF OF ALASKA MIDWEEK AND PRODUCE THE MOST ACTIVE
SHORTWAVE ALONG THE CANADIAN BORDER DURING THE PERIOD. THIS
FEATURE EVENTUALLY EVOLVES INTO A MORE AMPLIFIED UPPER LOW OVER
THE NORTHERN GREAT LAKES BY NEXT WEEKEND. AS IT PASSES ACROSS THE
NORTHERN ROCKIES WEDNESDAY AND THURSDAY...EXPECT SURFACE LOW
PRESSURE TO DEVELOP IN THE LEE OF THE ROCKIES WITH ENOUGH LOW
LEVEL CONVERGENCE TO ENHANCE MOISTURE AND CONVERGENCE AND RESULT
IN THE BEST CHANCES FOR AFTERNOON AND EVENING SHOWERS AND
THUNDERSTORMS DURING THE PERIOD. LINGERING INSTABILITY AS THE
SHORT-WAVE TROUGH MOVES EAST ALONG THE CANADIAN BORDER WARRANTS
CONTINUING TO HAVE A SLIGHT CHANCE FOR THUNDERSTORMS FRIDAY
AFTERNOON AND EVENING...AND THIS WILL ALSO ACCOUNT FOR THE
POTENTIALLY SLOWER MOVEMENT OF THIS FEATURE. CANNOT COMPLETELY
RULE OUT AN ISOLATED SHOWER OR THUNDERSTORM SATURDAY AND SUNDAY
BUT WITH MODELS SHOWING VERY LIMITED MOISTURE AVAILABLE...FEEL AT
THIS TIME THAT CHANCES ARE LOW ENOUGH TO LEAVE OUT MENTION OF
CONVECTION IN DAY 6 AND 7.

AFTERNOON HIGH TEMPERATURES WILL BE ABOVE NORMAL THROUGH THE
PERIOD...BUT WILL LIKELY BE WARMEST NEXT WEEKEND AS THE UPPER
LEVEL RIDGE AMPLIFIES AGAIN ACROSS THE WEST.

&&

.AVIATION...MAINLY VFR CONDITIONS EXPECTED THROUGH MONDAY EXCEPT IN
VCTY OF TSTRMS THIS EVENING AND AGAIN MONDAY AFTERNOON/EVENING...
WHERE PERIOD OF LOWER CIGS/LOW VSBYS LIKELY.

&&

.CYS WATCHES/WARNINGS/ADVISORIES...
