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, 12:30 PM MDT, 3 hours 26 minutes earlier.
Area forecast discussion, Jun 2, 12:30 PM MDT, 3 hours 26 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHEYENNE WY 1230 PM MDT TUE JUN 2 2015 .UPDATE... ISSUED AT 1208 PM MDT TUE JUN 2 2015 MAIN CONCERN TODAY WILL BE THIS AFTERNOON AND EARLY THIS EVENING NORTH OF THE NORTH PLATTE RIVER VALLEY. SHOWERS ARE STARTING TO DEVELOP EARLY THIS AFTERNOON EAST OF THE LARAMIE RANGE...WITH TSTORMS LIKELY TO DEVELOP SHORTLY. THIS ACTIVITY WILL PUSH INTO FAR EASTERN WYOMING AND WESTERN NEBRASKA OVER THE NEXT FEW HOURS. SOME OF THESE THUNDERSTORMS MAY BECOME SEVERE WITH LARGE HAIL...VERY HEAVY RAINFALL...AND STRONG WINDS POSSIBLE. CURRENT OBSERVATIONS DO SHOW SOME DRIER AIR TRYING TO PUSH ACROSS SOUTHERN WYOMING AND INTO THE HIGH PLAINS. NOT SURE HOW FAR THIS DRIER AIR WILL ADVECT EASTWARD...BUT THIS MAY LESSEN OUR SEVERE THREAT THIS AFTERNOON FROM DOUGLAS TO CHADRON. 0-6 KM SHEAR IS AROUND 40 TO 45 KNOTS IN THESE AREAS...SO WILL MONITOR CLOSELY THIS AFTERNOON. FOR NOW...EXPECT MAYBE ONE OR TWO SEVERE CELLS TO DEVELOP IN RURAL AREAS. && .SHORT TERM...(TODAY THROUGH THURSDAY) ISSUED AT 411 AM MDT TUE JUN 2 2015 ANOTHER WARM DAY EXPECTED ACROSS THE CWA TODAY...AIDED IN PART BY SOME DOWNSLOPING FLOW BEHIND A SFC TROF THAT WILL EDGE NORTHEAST INTO EAST CENTRAL WY AND THE NEB PANHANDLE. THIS SFC TROF MAY FOCUS SOME TSTRM ACTIVITY THIS AFTERNOON AND EVENING WITH DECENT CAPES LURKING VERY CLOSE TO THE EAST PART OF THE CWA IF NOT JUST A LITTLE INSIDE. ANY CONVECTION SHOULD MOVE EAST OF THE CWA BY LATE THIS EVENING AS A MINOR UPPER IMPULSE LIFTS NORTHEAST OF THE CWA. A COOL FRONT WILL SINK SOUTHEAST ACROSS THE CWA LATER THIS EVENING AND OVERNIGHT IN THE WAKE OF THE UPPER IMPULSE WITH MOIST UPSLOPE FLOW DEVELOPING OVER THE PLAINS LATER TONIGHT AND WEDS. EXPECT TO SEE A FAIRLY WIDESPREAD AREA OF LOW CLOUDS ACROSS MUCH OF THE PLAINS WEDS AND THIS COULD IMPACT CONVECTIVE INITIATION DURING THE DAY. CAPES FROM 1500-2000 J/KG PROGGED OVER MUCH OF THE CWA WEDS BUT IT MAY BE A RELATIVELY LATE SHOW FOR STORMS WITH THE NEXT UPPER IMPULSE ARRIVING MORE TOWARDS WEDS EVENING. SOME STRONG TO SEVERE STORMS MORE LIKELY WITH BETTER SHEAR EXPECTED WITH ACTIVITY LIKELY CONTINUING OVER THE PLAINS WEDS EVENING. NO BIG CHANGES SEEN FOR THURSDAY WITH STRONG/SEVERE STORMS POSSIBLE ONCE AGAIN MAINLY OVER THE PANHANDLE WHERE RETREATING SFC BOUNDARY WILL HELP TO FOCUS CONVECTION THOUGH BUILDING HEIGHTS MAY HINDER IT SOME. .LONG TERM...(THURSDAY NIGHT THROUGH MONDAY) ISSUED AT 411 AM MDT TUE JUN 2 2015 MODELS CONTINUE TO SHOW AN UPPER LEVEL LOW STALLING IN SOUTHERN CALIFORNIA THROUGH THE WEEKEND...SHIFTING NORTHWEST INTO NEVADA BY SUNDAY AND WEAKENING. AN UPPER RIDGE WILL AMPLIFY DOWNSTREAM OF THE TROUGH WITH THE AXIS SITUATED OVER THE CENTRAL AND HIGH PLAINS THROUGH SATURDAY...AND SHIFTING WESTWARD OVER THE ROCKIES BY SUNDAY. WITHIN THIS SYNOPTIC PATTERN...SHOULD SEE CONTINUED ENERGETIC SOUTHWEST FLOW OVER THE CWA WITH CHANCES FOR SHOWERS AND THUNDERSTORMS EXPECTED EACH DAY. TO START...LOOKING AT A FEW STRONG/SEVERE STORMS THURSDAY EVENING OVER THE PANHANDLE WITH SBCAPES PROGGED BETWEEN 1000-3000 J/KG AND 30 KTS OF DEEP LAYER SHEAR OVER THIS AREA. CONTINUED MOIST SOUTHEAST SFC FLOW POSSIBLY ENHANCED BY THUNDERSTORMS OUTFLOW WILL LIKELY BRING A RETURN OF STRATUS/FOG OVER THE PLAINS EARLY FRIDAY MORNING. A POTENT SHORTWAVE MOVING UP INTO WYOMING FROM THE SOUTH ON FRIDAY WILL STRENGTHEN SOUTHEAST SFC WINDS ACROSS THE CWA...WITH INCREASED VEERING FLOW PROGGED IN THE MID AND UPPER LEVELS AS WELL. LOOKING AT A BROADER COVERAGE OF CONVECTION ACROSS THE CWA AS A RESULT...WITH PERHAPS A FEW MORE STRONG/SEVERE STORMS WITH BULK SHEAR OF 30-40KTS. ANOTHER NIGHT OF STRATUS/FOG POTENTIAL FOR EARLY SATURDAY MORNING...THEN A COLD FRONT WILL DROP SOUTH ACROSS THE AREA DURING THE DAY ON SATURDAY. ANTICIPATE A GOOD CHANCE FOR SHOWERS/STORMS WITH THE FRONT FOR SATURDAY...THEN SHOULD BE MORE FOCUSED OVER THE MOUNTAINS FOR SUNDAY AS THE FRONT STALLS ALONG THE ROCKIES. SATURDAY STILL LOOKS LIKE THE WARMEST DAY WITH THE THERMAL RIDGE OVERHEAD...AND A FAIR NUMBER OF LOCATIONS ACROSS THE PLAINS WILL BE PUSHING 80F. PERSISTENT MOIST SOUTHERLY UPSLOPE FLOW ON MONDAY WILL MAINTAIN A GOOD CHANCE FOR SHOWERS AND THUNDERSTORMS IN THE AFTERNOON. && .AVIATION...(FOR THE 18Z TAFS THROUGH 18Z WEDNESDAY AFTERNOON) ISSUED AT 1210 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 411 AM MDT TUE JUN 2 2015 NO CONCERNS SEEN IN THE NEAR FUTURE WITH FUELS PRETTY MUCH IN GREENUP AND WEATHER FACTORS REMAINING NON-CRITICAL. WARM TODAY THEN TEMPERATURES WILL LOWER TO NEAR SEASONAL NORMS FOR THE REST OF THE WEEK. && .HYDROLOGY... ISSUED AT 411 AM MDT TUE JUN 2 2015 THE LARAMIE RIVER NEAR FT LARAMIE AND THE LOWER N PLATTE RIVER WILL CONTINUE TO FALL SLOWLY OVER THE NEXT FEW DAYS AND BE ENTIRELY BELOW FLOOD STAGES BY THURSDAY MORNING. MEANWHILE INCREASING SNOW MELT OVER THE MTNS WILL RAISE THE UPPER N PLATTE DURING THE WEEK BUT NOT YET EXPECTED TO ATTAIN FLOOD STAGE. WILL HAVE TO MONITOR RIVERS FOR ANY EFFECTS FROM RUNOFF FROM ANY HEAVIER RAINS. && .CYS WATCHES/WARNINGS/ADVISORIES... WY...NONE.
