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 14, 6:15 PM MDT, 44 minutes earlier.

Area forecast discussion, Jun 14, 6:15 PM MDT, 44 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
615 PM MDT SAT JUN 14 2014

.SHORT TERM...(THIS EVENING THROUGH MONDAY NIGHT)
ISSUED AT 345 PM MDT SAT JUN 14 2014

CURRENT VISIBLE AND WATER VAPOR SATELLITE LOOP SHOWS THE UPPER
LEVEL TROUGH AXIS QUICKLY MOVING EASTWARD ACROSS WESTERN WYOMING.
THE LEADING EDGE OF THIS TROUGH AXIS IS CURRENTLY MOVING INTO THE
HIGH PLAINS THIS AFTERNOON WITH DEVELOPING CONVECTION ALONG THE
LARAMIE RANGE SOUTHWARD INTO CENTRAL COLORADO. WITH THE DIVERGENT
PORTION OF AN UPPER LEVEL JET ACROSS COLORADO...EXPECT CONVECTION
INITIATION TO RAPIDLY EXPAND AND INTENSIFY IN THE NEXT 1 TO 3
HOURS DUE TO ENHANCED INSTABILITY WITH COOLER AIR MOVING INTO THE
REGION ALOFT IN ADDITION TO THE COLD FRONT STALLING NEAR THE ROCKY
MOUNTAINS PROVIDE ADEQUATE LLVL CONVERGENCE. ALTHOUGH TEMPERATURES
ARE NOT VERY WARM BEHIND THIS FRONT...BELIEVE THERE IS ENOUGH
FORCING NEAR THE SURFACE AND ALOFT TO TRIGGER ISOLATED STRONG TO
SEVERE TSTORMS ALONG AND EAST OF THE LARAMIE RANGE...BUT THIS MAY
BE RIGHT AROUND THE COLORADO BORDER. MOST OF THE ACTIVITY WILL
RESULT IN HEAVY RAIN...GUSTY WINDS...AND MAYBE SOME SMALL HAIL.

CONDITIONS WILL RAPIDLY IMPROVE BY LATE THIS EVENING AS SURFACE
WINDS BACK INTO THE WEST WHILE THE UPPER LEVEL TROUGH MOVES EAST OF
THE FORECAST AREA TONIGHT. SKIES WILL CLEAR ALLOWING DECENT
RADIATIONAL COOLING OVERNIGHT. A FEW AREAS WEST OF THE LARAMIE
RANGE WILL SEE LOW TEMPERATURES NEAR FREEZING BY EARLY SUNDAY
MORNING. THOUGHT ABOUT ISSUING A FROST ADVISORY FOR THE LARAMIE
VALLEY...BUT WITH DRIER AIR MOVING INTO THE AREA AND WINDS AROUND
10 MPH DO NOT BELIEVE THE COVERAGE WILL BE THAT HIGH.

SUNDAY WILL CONTINUE TO BE ON THE COOL SIDE AND BELOW NORMAL FOR
THIS TIME OF THE YEAR WITH HIGHS IN THE 60S AND 70S BEHIND THE
COLD FRONT. IT WILL BE DRY HOWEVER...SO OVERALL A PLEASANT DAY
WITH POP BELOW 10 PERCENT. THE WARMING TREND CONTINUES INTO MONDAY
AS MODELS SHOW AN UPPER LEVEL LOW DIGGING SOUTHEAST INTO THE
PACIFIC NORTHWEST. THIS WILL RESULT IN INCREASING SOUTHWEST FLOW
OVER SOUTHEAST WYOMING AND WESTERN NEBRASKA WITH TEMPERATURES
INCREASING INTO THE UPPER 70S TO UPPER 80S...WARMEST OVER WESTERN
NEBRASKA. MONDAY WILL GENERALLY BE DRY...BUT CAN NOT RULE OUT A
FEW THUNDERSTORMS ALONG AND NORTH OF THE PINE RIDGE AS A WEAK
SHORTWAVE EMBEDDED IN THE SOUTHWEST FLOW ALOFT...MOVES OVER THE
EASTERN PLAINS.

.LONG TERM...(TUESDAY THROUGH SATURDAY)
ISSUED AT 345 PM MDT SAT JUN 14 2014

12Z MODELS SUPPORT THE TREND OF SHEARING THE UPPER LOW INTO TWO
PIECES OF ENERGY...ONE THAT WILL JET NORTHWARD INTO CANADA WITH A
SECOND TO MOVE ACROSS THE ROCKIES TUESDAY NIGHT INTO WEDNESDAY.
THE DRY MIDLEVEL AIRMASS APPEARS TO BE A BIT MORE MOIST COMPARED
TO YESTERDAYS SOLUTIONS...WHICH IS LIKELY A RESULT OF THIS SECOND
WAVE DIGGING FURTHER SOUTH AND THUS PUSHING SOME OF THE AVAILABLE
MIDLEVEL MOISTURE INTO THE CWA. WILL STICK WITH THE ECMWF/GFS
SOLUTIONS FOR THIS FORECAST AS THE NAM IS THE PROGRESSIVE OUTLIER.
AN INITIAL PACIFIC FRONT WILL BEGIN TO SLOWLY MOVE EASTWARD ACROSS
THE CWA TUESDAY AFTERNOON AND EVENING...WITH VERY WARM TEMPS
EXPECTED AHEAD OF THE FRONT ALONG WITH WIDESPREAD GUSTY SOUTHWEST
WINDS. A SLIGHT CHANCE FOR SHOWERS AND THUNDERSTORMS WILL THEN
ACCOMPANY THE FRONT AS IT SLOWLY MOVES THROUGH. A SECOND COLD
FRONT WILL DROP SOUTH ON WEDNESDAY AFTERNOON AS THE SOUTHERN PIECE
OF ENERGY MOVES TOWARD THE ROCKIES...AND WILL ADVECT IN HIGHER LOW
AND MID LEVEL MOISTURE. THIS PIECE OF ENERGY WILL MOVE SLOWLY
ACROSS THE REGION ON WEDNESDAY NIGHT AND THURSDAY AND WILL BRING
A BETTER CHANCE FOR SHOWERS AND T-STORMS THROUGH THIS TIME FOR
MUCH OF THE CWA. WRAPAROUND MOISTURE AND COOLER TEMPS ALOFT WILL
MAINTAIN A SLIGHT CHANCE FOR STORMS ON THURSDAY...WITH MUCH DRIER
AIR FILTERING IN FOR FRIDAY AND SATURDAY IN THE WAKE OF THIS
SYSTEM. A RIDGE OF HIGH PRESSURE WILL BUILD IN FROM THE WEST ON
FRIDAY AND SATURDAY AND WILL BRING A RETURN OF VERY WARM DAYTIME
TEMPERATURES.

&&

.AVIATION...(FOR THE 00Z TAFS THROUGH 00Z SUNDAY AFTERNOON)
ISSUED AT 611 PM MDT SAT JUN 14 2014

RAIN WILL CONTINUE AT SNY THROUGH AROUND 02Z AND THEN TAPER OFF.
COULD BE BRIEF PERIODS OF MVFR VIS WITH THE HEAVIER RAIN.
ELSEWHERE ACROSS THE REGION...ONLY ISOLATED SHOWERS THROUGH THE
EVENING ARE EXPECTED. SOUTHWEST TO WEST WINDS WILL OCCASIONALLY
GUST TO 25 KTS THROUGH THE EVENING OVER SOUTHEAST WY.

&&

.FIRE WEATHER...

ISSUED AT 345 PM MDT SAT JUN 14 2014

SCATTERED SHOWERS AND THUNDERSTORMS ARE EXPECTED THIS EVENING WITH
THE BEST COVERAGE NEAR THE COLORADO STATE LINE. TEMPERATURES WILL
REMAIN COOLER THAN NORMAL THIS WEEKEND WITH DAYTIME HUMIDITIES ONLY
FALLING INTO THE 20S AND 30S PERCENT RANGE. WARM...DRY AND BREEZY
CONDITIONS WILL DEVELOP EARLY NEXT WEEK. THIS WILL ELEVATE FIRE
WEATHER CONCERNS...ESPECIALLY WEST OF THE LARAMIE RANGE ON MONDAY
AND TUESDAY. HOWEVER...ANOTHER COLD FRONT WILL PUSH INTO THE AREA
ON WEDNESDAY RESULTING IN COOLER TEMPERATURES AND HIGHER
HUMIDITIES.

&&

.HYDROLOGY...
ISSUED AT 345 PM MDT SAT JUN 14 2014

RIVER LEVELS WILL CONTINUE TO FALL THROUGH THE WEEKEND WITH COOLER
THAN NORMAL TEMPERATURES EXPECTED OVER THE MOUNTAINS. STILL SOME
HEALTHY SNOW PACK ABOVE 10000 FEET IN THE SNOWY AND SIERRA MADRE
RANGES...SO A RAPID WARM UP COULD RELEASE THIS WATER FOR FUTURE
RISES IN RIVERS. IN ADDITION...WILL HAVE TO MONITOR A POTENTIAL
RAINFALL EVENT DURING THE MIDDLE OF NEXT WEEK OVER THE MOUNTAINS.
