The episode as NWS CYS wrote it up.
Thunderstorms over the southern half of the western Nebraska Panhandle produced large hail and damaging winds.
The local office's own words before the first event, 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 the first event at Jun 1, 2:26 PM MST, 54 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHEYENNE WY 326 PM MDT SUN JUN 1 2014 .SHORT TERM...(THIS AFTERNOON THROUGH TUESDAY) ISSUED AT 3 PM MDT SUN JUN 1 2014 SHORTWAVE IS CURRENTLY MOVING TO THE NORTH OF THE CWA WITH ITS AXIS ACROSS THE NEBRASKA PANHANDLE. COLD FRONT HAS PUSHED ACROSS THE PLAINS WITH WINDS GOING NORTH TO NORTHEAST. AN AREA OF SHOWERS AND EMBEDDED TSTMS IS MOVING OVER MUCH OF CONVERSE/NIOBRARA COUNTIES AND SHOULD PUSH INTO THE NORTHERN PANHANDLE OVER THE NEXT FEW HOURS. WEAK INSTABILITY IS SHOWN UP IN THIS REGION...LARGELY CAUSED BY COOL MIDLVL TEMPS. NOT REAL CONFIDENT THAT WE WILL SEE SVR STORMS THROUGH THE AFTN OVER THE CWA...HOWEVER THE BEST SHOT WOULD BE FROM CHEYENNE TO SIDNEY ALONG THE COLORADO BORDER. THIS IS WHERE THE SPC MESOANALYSIS SHOWS 1000-1500 J/KG OF MLCAPE CO-LOCATED WITH 40 KTS OF BULK SHEAR. THE LARGE SCALE SUBSIDENCE BEHIND THE SHORTWAVE COMBINED WITH A WEAK FRONTAL INVERSION AND DECREASING INSTABILITY BY LATE AFTN ARE NEGATIVES FOR STRONGER STORMS. THE HRRR MODEL HAS BEEN CONSISTENT WITH LITTLE IF ANY STORMS DEVELOPING IN AREAS ALONG THE COLORADO BORDER. STORMS WILL WIND DOWN BY LATE EVENING...NOT EXPECTING A REPEAT OF LAST NIGHT WHERE STORMS LINGERED LATE INTO THE NIGHT. QUIET WEATHER DAY ON MONDAY AS A SHORTWAVE MIDLVL RIDGE MOVES OVERHEAD WITH SFC WINDS TURNING TO THE SE ACROSS THE PLAINS. THE MODELS ARE NOT INDICATING MUCH QPF AT ALL...WHICH MAKES SENSE WITH THE RIDGING ALOFT AND WEAK INSTABILITY. TEMPS COME UP ABOUT 5 DEGREES COMPARED TO TODAY. SOUTHWESTERLY FLOW ALOFT STRENGTHENS BY TUESDAY WITH SHORTWAVE MOVING THROUGH DURING THE AFTN. THE TIMING OF THE WAVE IS SUCH THAT THE DRYLINE IS LOCATED OVER THE PANHANDLE DURING THE AFTN WITH VERY MOIST CONDITIONS TO THE EAST. THIS BOUNDARY WILL BE THE FOCUS FOR CONVECTIVE INITIATION AND DEWPOINTS ARE PROGGED TO BE IN THE VERY HIGH (60-65F) TO THE EAST. INSTABILITY IS EXCELLENT (LI VALUES OF -9C) AS IS DEEP LAYER SHEAR...SO WILL DEFINITELY HAVE TO WATCH FOR SVR STORMS OVER OUR EASTERN ZONES. OF COURSE IF THE WAVE IS SLOWER AND THE SFC TROUGH IS FURTHER WEST AND SOUTHEAST WINDS BACK UP ALONG THE LARAMIE RANGE THEN THE SVR THREAT WOULD EXTEND TO ALMOST THE ENTIRE PLAINS. .LONG TERM...(TUESDAY NIGHT THROUGH SATURDAY) ISSUED AT 3 PM MDT SUN JUN 1 2014 GFS SHOWS MAIN SHORTWAVE PRODUCING SCATTERED CONVECTION LATE TUESDAY LIFTING OUT TO THE NORTHEAST EARLY WEDNESDAY WITH A MID/UPPER DRYSLOT WORKING IN ACROSS THE SOUTHERN HALF OF THE FORECAST AREA. ECMWF ON WEDNESDAY A LITTLE LESS AGGRESSIVE THIS FAR NORTH WITH THE UPPER DRYSLOT AND HENCE WOULD SUGGEST SOMEWHAT GREATER CHANCE FOR AFTERNOON/EVENING CONVECTION ACROSS OUR AREA AND OUR OFFICIAL FORECAST WILL ADVERTISE CHANCE POPS NORTH AND SLIGHT CHANCE FOR THUNDERSTORMS IN THE SOUTH. FOR THURSDAY AND BEYOND... GFS AND ECMWF DEPICT OVERALL MID/UPPER SYNOPTIC PATTERN TO BE WEST-SOUTHWESTERLY AND FAIRLY ACTIVE FOR MUCH OF NEXT WEEK. SEMI- ZONAL PATTERN ALOFT WILL LIKELY RESULT IN TIMING UNCERTAINTIES WHEN EACH PIECE OF SHORTWAVE ENERGY WILL TRAVERSE OUR AREA...SO WE KEPT AT LEAST SOME POPS GOING MOST AREAS WITH CHANCE POPS CONCENTRATED IN THE AFTERNOON/EVENING HOURS THROUGH SATURDAY...THEN WE BACKED POPS OFF A BIT BY NEXT SUNDAY AS GFS (AND TO SOME DEGREE THE ECMWF) DEPICTS A LARGESCALE TROUGH AMPLIFYING TO OUR EAST WITH RIDGING WORKING IN FROM THE WEST. THE ECMWF IS LESS BULLISH ON AMPLIFYING THE EASTERN TROUGH...SO WE MAY END UP RAISING POPS FOR SUNDAY ON SUBSEQUENT ISSUANCES. && .AVIATION...(FOR THE 18Z TAFS THROUGH 18Z MONDAY MORNING) ISSUED AT 1202 PM MDT SUN JUN 1 2014 COLD FRONTAL BOUNDARY GETTING A SHOVE SOUTH OF THE COLORADO BORDER AS THE LEADING SHORTWAVE AHEAD OF A PASSING LOW OVER SOUTHERN MONTANA EJECTS EASTWARD ACROSS THE WESTERN NEBRASKA PANHANDLE. THERE IS STILL ENOUGH MIDLEVEL INSTABILITY BEHIND THE FRONT TO GENERATE SCATTERED SCATTERED THUNDERSTORMS NORTH OF A LINE FROM MEDICINE BOW WY TO KIMBALL NE TODAY...MEANING BETTER CHANCES FOR THUNDERSTORMS THROUGH EARLY EVENING WOULD BE IN THE CHADRON...SCOTTSBLUFF...ALLIANCE AND SIDNEY AREAS FOR AVIATION FORECAST PURPOSES. ALSO...GETTING SOME ISOLATED SHOWERS DEVELOPING IN THE HIGHER TERRAIN AROUND RAWLINS AND LARAMIE...AND INCLUDED VCNTY MENTION OF THUNDERSTORMS THIS AFTERNOON AT THOSE AIRPORTS. HRRR MODEL DOES SHOW SOME LINGERING CONVECTION IN THE 01Z-03Z TIMEFRAME OVER THE NEBRASKA PANHANDLE...BUT AS THE UPPER LOW OVER MONTANA LIFTS A BIT FARTHER OUT TO THE NORTHEAST TONIGHT AND WITH THE LACK OF DYNAMIC FORCING ALOFT AND WITH WEAK LOW LEVEL INSTABILITY...EXPECT ANY LINGERING THUNDERSTORM ACTIVITY AFTER 02Z TO QUICKLY DIMINISH BY LATE EVENING. && .FIRE WEATHER... ISSUED AT 300 PM MDT SUN JUN 1 2014 MINIMAL FIRE WEATHER CONCERNS OVER THE NEXT FEW DAYS. SCATTERED SHOWERS AND THUNDERSTORMS WILL BE POSSIBLE OVER MUCH OF THE AREA THROUGH THIS EVENING BEFORE CONDITIONS DRY OUT EARLY NEXT WEEK...ESPECIALLY ALONG AND WEST OF THE LARAMIE RANGE. FOR AREAS WEST OF THE LARAMIE RANGE...A DRIER AIRMASS WILL CAUSE MINIMUM HUMIDITY VALUES TO DROP TO AROUND 20 PERCENT BY MONDAY AFTERNOON AND THEN TO 15 PERCENT BY TUESDAY. SOUTHWEST WINDS WILL ALSO BE GUSTY ON TUESDAY AFTERNOON...HOWEVER A CRITICAL FIRE WEATHER THREAT IS NOT FORECASTED SINCE FUELS ARE NOT SUPPORTIVE FOR FIRE GROWTH. .HYDROLOGY... ISSUED AT 3 PM MDT SUN JUN 1 2014 RIVER FLOODING WILL CONTINUE ALONG THE LITTLE SNAKE...UPPER NORTH PLATTE...AND LARAMIE RIVERS THROUGH THE MIDDLE OF NEXT WEEK. HOWEVER SIGNIFICANT RISES ARE NOT EXPECTED AND STAGES SHOULD BEGIN TO RECEDE THROUGH MIDWEEK. A DRY WEATHER PATTERN WILL DEVELOP TO THE WEST OF THE LARAMIE RANGE OVER THE NEXT FEW DAYS AS MOISTURE DECREASES. TEMPERATURES WILL BE SEASONAL...PRODUCING SOME SNOWMELT EACH DAY. && .CYS WATCHES/WARNINGS/ADVISORIES... WY...NONE.
