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 2, 4:30 PM MDT, 1 hour 53 minutes earlier.

Area forecast discussion, Jun 2, 4:30 PM MDT, 1 hour 53 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
430 PM MDT TUE JUN 2 2015

.SHORT TERM...(THIS EVENING THROUGH THURSDAY NIGHT)
ISSUED AT 415 PM MDT TUE JUN 2 2015

MAIN FORECAST CONCERN IN THE SHORT TERM IS SEVERE WEATHER AS
THUNDERSTORMS HAVE DEVELOPED ACROSS THE EASTERN PLAINS OF WYOMING
AND ARE CURRENTLY MOVING INTO A MORE FAVORABLE ENVIRONMENT. THERE
HAVE BEEN A FEW STRONGER CELLS SO FAR...AND THIS TREND WILL
CONTINUE INTO THIS EVENING. A SEVERE THUNDERSTORM WATCH REMAINS IN
EFFECT NORTHEAST OF A LINE FROM LUSK WYOMING TO BRIDGEPORT
NEBRASKA. ACTIVITY SHOULD DIMINISH AN MOVE OUT OF THE FORECAST
AREA BY LATE THIS EVENING. FURTHER WEST...NOT MUCH GOING ON SINCE
DRIER AIR HAS TEMPORARILY MOVED INTO MOST OF SOUTHEAST WYOMING
WITH DEWPOINTS CURRENTLY IN THE UPPER 20S TO UPPER 30S.

WILL HAVE TO KEEP A CLOSE EYE ON WEDNESDAY AS SOME MODELS ARE
INDICATING AN ACTIVE SEVERE WEATHER DAY ACROSS MOST OF SOUTHEAST
WYOMING AND WESTERN NEBRASKA AS AN UPPER LEVEL DISTURBANCE MOVES
OVERHEAD EMBEDDED IN SOUTHWEST FLOW ALOFT. MODELS SHOW CAPE
VALUES BETWEEN 1500 TO 2500 J/KG...AND EVEN CLOSE TO 3000 J/KG
ACROSS THE AREA WITH LOW LI/S...LLVL CONVERGENCE AND MOIST UPSLOPE
FLOW. THE 12Z NAM ON THE OTHER HAND SHOWS LOW STRATUS ACROSS THE
HIGH PLAINS EAST OF THE LARAMIE RANGE WITH ANY CONVECTION MAINLY
OVER THE HIGHER TERRAIN WEST OF THE LARAMIE RANGE...SLOWLY MOVING
EASTWARD DURING THE AFTERNOON AND EVENING WITH A LOWER CHANCE OF
SEVERE WEATHER. THE NEW 18Z NAM IS NOW TRENDING TOWARDS THE GFS
HOWEVER. FOR NOW...EXPECT SOME FOG AND LOW STRATUS TO DEVELOP
TONIGHT...SO THE QUESTION IS HOW DEEP WILL THIS SATURATED LAYER BE
AND HOW LONG IT WILL LAST. CURRENTLY THINKING IS THE DRIER AIR
THAT HAS PUSHED ACROSS THE SOUTHERN PORTION OF THE FORECAST AREA
WILL ACTUALLY SUPPRESS THE POTENTIAL FOR LOW CLOUDS AND FOG
TONIGHT. IT MAY STAY CLOUD UP AS FAR WEST AS THE LARAMIE
RANGE...BUT BELIEVE THE DEPTH WILL BE SHALLOW. SUNSHINE IN THE
LATE MORNING AND AFTERNOON TOMORROW WILL QUICKLY LEAD TO AN
UNSTABLE BOUNDARY LAYER. IN ADDITION...A CAP INVERSION BELOW 700MB
WILL SUPPRESS CONVECTION INITIALLY...BUT ONCE THIS CAP IS ERODEDIN
THE AFTERNOON...BELIEVE TSTORM DEVELOPMENT WILL VERY RAPID ALONG
THE LARAMIE RANGE OR JUST WEST. IT WILL BE COOLER ON WEDNESDAY AS
WELL WITH HIGHS IN THE 70S. THIS CONVECTION MAY LINGER THROUGH
WEDNESDAY NIGHT AS WELL DUE TO THE RELATIVE SLOW MOTION OF THE
UPPER LEVEL SHORTWAVE DISTURBANCE.

YET ANOTHER ROUND OF SHOWERS AND TSTORMS WITH THE POTENTIAL OF
STRONG TO SEVERE STORMS ARE EXPECTED ON THURSDAY. THURSDAY MAY
ACTUALLY BE SIMILAR TO WEDNESDAY...WITH SLIGHTLY LESS POTENTIAL
FOR SEVERE TSTORMS.

.LONG TERM...(FRIDAY THROUGH TUESDAY)
ISSUED AT 202 PM MDT TUE JUN 2 2015

CHANCES FOR SHOWERS AND THUNDERSTORMS WILL CONTINUE THROUGH THE
LONG TERM FORECAST PERIOD AS CURRENT WEATHER PATTERN GENERALLY
REMAINS IN PLACE. SUBTLE TROUGH CURRENTLY OVER THE NORTHWEST
CONUS WILL DEEPEN LATE THIS WEEK WITH AN UPPER LEVEL LOW
EVENTUALLY CUTTING OFF OVER THE SOUTHWEST CONUS. THIS WILL KEEP
THE FORECAST AREA UNDER SOUTHWEST FLOW ALOFT WITH GENERALLY EAST
FLOW IN THE LOW LEVELS. THEREFORE MOIST LOW LEVEL UPSLOPE FLOW
AND PERIODIC SHORTWAVES WILL CONTINUE TO BRING CHANCES FOR SHOWERS
AND THUNDERSTORMS ON A DAILY BASIS. THE MAIN CHANCES WILL BE
DURING THE AFTERNOON AND EVENING TIME FRAMES BUT WITH SUBTLE
SHORTWAVE FEATURES...NOCTURNAL CONVECTION WILL BE POSSIBLE MANY
NIGHTS.

&&

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z WEDNESDAY AFTERNOON)
ISSUED AT 202 PM MDT TUE JUN 2 2015

THE INITIAL AVIATION CONCERN WILL BE THE POTENTIAL FOR
THUNDERSTORMS AT WRN NEBRASKA PANHANDLE TERMINALS 02/21Z-03/03Z.
HAVE KEPT VCTS GOING AT TAF SITES SINCE THE LOCATION AND TIMING OF
INDIVIDUAL STORMS IS FRUITLESS UNTIL THEY DEVELOP. THIS ACTIVITY
WILL WIND DOWN AFTER 03Z...GIVING WAY TO THE NEXT AVIATION CONCERN
WHICH WILL BE LOW FOG/STRATUS DEVELOPMENT AFTER 03/09Z. SIMILAR TO
THE THUNDERSTORMS...THIS FOG AND LOW STRATUS SHOULD MAINLY AFFECT
WRN NEBRASKA SITES. THE MAIN QUESTION IS JUST HOW FAR WEST THE
STRATUS/LOW CLOUDS MAKE IT. FOR NOW HAVE TRENDED KCYS DOWN SOME
TOWARDS DAYBREAK WEDNESDAY...BUT MAY NEED GO FURTHER SHOULD TRENDS
CONTINUE. KEPT CONDITIONS MVFR FOR PANHANDLE AIRPORTS...THOUGH
WOULD NOT BE SURPRISED TO SEE A FEW BRIEFLY DROP INTO IFR. WILL
WAIT FOR ADDL SPECIFICS BEFORE DROPPING THEM MUCH LOWER.

&&

.FIRE WEATHER...
ISSUED AT 202 PM MDT TUE JUN 2 2015

NO FIRE WEATHER CONCERNS THIS WEEK AND THIS WEEKEND WITH GREEN
FUELS AND A DAILY CHANCE OF SHOWERS AND THUNDERSTORMS WITH
POTENTIAL FOR MODERATE TO HEAVY RAINFALL. THIS DRIEST DAY WILL
ACTUALLY BE TODAY WITH HUMIDITIES NEAR 20 PERCENT OVER PORTIONS OF
SOUTHEAST WYOMING. DAYTIME HUMIDITIES WILL TREND HIGHER THROUGH
THE WEEK WITH VALUES RANGING BETWEEN 40 TO 60 PERCENT BY FRIDAY.

&&

.HYDROLOGY...
ISSUED AT 202 PM MDT TUE JUN 2 2015

THE NORTH PLATTE RIVER WILL CONTINUE TO FALL THIS WEEK AS UPSTREAM
RESEVOIRS LIMIT THEIR RELEASES. HOWEVER...MITCHELL WILL REMAIN
ABOVE FLOOD STAGE THROUGH WEDNESDAY BEFORE FALLING BELOW FLOOD
STAGE BY THURSDAY MORNING. OTHERWISE...THE NORTH PLATTE RIVER FROM
HENRY TO MINATARE WILL REMAIN IN ACTION STAGE OF THE NEXT FEW
DAYS.

RIVER LEVELS WILL INCREASE ALONG THE LARAMIE RIVER AT
LARAMIE...WITH LEVELS FORECAST TO RISE ABOVE FLOOD STAGE ON
FRIDAY. STAGE AT FORT LARAMIE WILL REMAIN ELEVATED THROUGH THE
WEEK.
