The episode as NWS GLD wrote it up.
During the mid to late evening a line of slow moving storms produced heavy rainfall over northwest Yuma county. Water and mud was reported to be crossing Highway 34 north of Road 39. A land owner near this location reported parts of his property were under three to four feet of water. A few miles further east flood waters were also reported over Highway 59 just north of town. The emergency manager in Yuma measured 0.83 of rainfall in 30 minutes. Total rainfall fall amounts ranged from 1.20 to 2.50.
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 Goodland, KS wrote its last area forecast discussion before the first event at Jun 1, 4:30 PM MST, 4 hours 30 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GOODLAND KS 530 PM MDT MON JUN 1 2015 .SHORT TERM...(THIS EVENING THROUGH TUESDAY) ISSUED AT 149 PM MDT MON JUN 1 2015 RAP 500 MB ANALYSIS INDICATED A SHORTWAVE RIDGE ALONG THE FRONT RANGE OF COLORADO AND NEW MEXICO WITH A NEGATIVELY TILTED TROUGH OVER THE PACIFIC NORTHWEST AND THE EASTERN THIRD OF THE CONUS. WATER VAPOR IMAGERY SHOWED AVAILABLE MOISTURE OVER THE FRONT RANGE AND ALONG THE HIGH PLAINS REGION. VISIBLE IMAGERY SHOWED MOSTLY CLEAR SKIES ACROSS THE TRI STATE AREA WITH SOME PARTLY CLOUDY SKIES EAST OF HIGHWAY 283. ALTHOUGH THE UPPER LEVEL RIDGE IS IN PLACE...A SURFACE TROUGH ALONG THE FRONT RANGE WILL CREATE A SURFACE CONVERGENCE ZONE THAT WILL BECOME MORE APPARENT TOWARDS 00Z TONIGHT ALONG THE FRONT RANGE. HIRES ARW AND NMM GUIDANCE BOTH DEPICT THE CONVERGENCE ZONE MOVING EASTWARD INTO THE FORECAST AREA IN THE 3Z TO 6Z TIME FRAME TONIGHT. HIRES GUIDANCE ALSO SHOWS A SHORTWAVE TROUGH EMBEDDED WITHIN THE MAIN FLOW AS AN UPPER 35 TO 45 KT JET RIDES OVER TOP OF THE RIDGE...WHICH WILL ACT TO DESTABILIZE AND HELP DRIVE THE CONVECTION FOR A FEW HOURS TONIGHT. CAPE VALUES VARY BETWEEN MODELS...WITH RAP/GFS SHOWING UP TO 1500 J/KG...BUT HIRES ARW/NMM/NAM SHOW 2000 AND 3000 J/KG IN SOME PLACES. BULK SHEAR VALUES ARE NOT INDICATIVE OF WIDESPREAD SEVERE WEATHER...HOWEVER A FEW ISOLATED SEVERE STORMS ARE POSSIBLE. AFTER THE SHORT WINDOW OF HIGH CAPE VALUES PASS ACROSS THE FORECAST AREA WITH THE SURFACE CONVERGENCE ZONE...CONVECTION SHOULD TAPER OFF AFTER 9Z. SHOWERS WILL LINGER IN THE EASTERN PORTIONS OF THE FORECAST AREA UNTIL MORNING. FOG WILL DEVELOP EAST OF HIGHWAY 83 FOR SOME LOCATIONS WITH GOOD SURFACE MOISTURE ADVECTION DUE TO SOUTH TO SOUTHEASTERLY WINDS...BUT WILL DISSIPATE BY MID MORNING. LOW TEMPERATURES WILL BE IN THE UPPER 50S TO LOWER 60S DUE TO DEW POINTS IN THE UPPER 50S AND THE BLANKETING CLOUD COVER. SOUTHERLY ADVECTION WILL CONTINUE THROUGH TUESDAY...WHICH WILL ADVECT WARM TEMPERATURES IN THE MID TO UPPER 80S ACROSS THE TRI STATE AREA. WITH WARM SURFACE TEMPERATURES AND DEW POINTS IN THE LOWER 60S...CAPE VALUES WILL BE BETWEEN 2000 AND 3000 J/KG ACROSS MUCH OF THE FORECAST AREA...ESPECIALLY EAST OF HIGHWAY 83. A SIMILAR SET UP WILL BE PRESENT FOR EASTERN COLORADO DUE TO THE SURFACE LEE TROUGH WITH A CONVERGENCE ZONE ALONG THE KANSAS/COLORADO BORDER. FORECAST MODELS DO NOT HAVE STRONG CONVECTION DEPICTED...BUT GIVEN THE SET UP WITH THE CAPE SET UP...STRONG THUNDERSTORMS COULD DEVELOP IN EASTERN COLORADO FOR AT LEAST SOME OF THE EVENING HOURS. .LONG TERM...(TUESDAY NIGHT THROUGH MONDAY) ISSUED AT 237 PM MDT MON JUN 1 2015 TUESDAY NIGHT...WITH RELATIVELY WEAK HEIGHT FALLS AND BEST LIFT NORTH OF CWA TENDENCY SHOULD BE TOWARDS THUNDERSTORMS DECREASING IN COVERAGE DURING THE EVENING. COLD FRONT DROPPING SOUTH AFTER MIDNIGHT COULD PROVIDE SUPPORT FOR SHOWER/THUNDERSTORM REDEVELOPMENT...HOWEVER THERE IS A VERY WEAK PRECIP SIGNAL BETWEEN GUIDANCE AND LOWER CONFIDENCE THAT WE WOULD SEE MEASURABLE PRECIP THROUGH MONDAY MORNING. I KEPT SLIGHT CHANCE MENTION IN OUR NORTH TRANSLATING TO THE NORTHEAST WHERE GUIDANCE SHOWS BETTER CONSISTENCY. WEDNESDAY-WEDNESDAY NIGHT...COLD FRONT STALLS OVER OUR CWA WITH VARYING POSITIONS BETWEEN GUIDANCE. THIS IMPACTS LOCATION OF BEST COVERAGE AND POTENTIAL FOR SEVERE. WITH ANOMALOUSLY HIGH PWAT VALUES (AROUND 1.2") VERY GOOD MOISTURE FLUX AND AT LEAST MODERATE INSTABILITY (POSSIBLY AS HIGH AS 4000-5000 J/KG BASED ON NAM) WE SHOULD SEE NUMEROUS THUNDERSTORMS DEVELOP NORTH OF THE FRONT. WIND PROFILES GENERALLY FAVOR SPEED SHEER...THOUGH THERE COULD BE LIMITED LOW LEVEL VEERING AS A RESULT OF THE EAST-SOUTHEAST WINDS ALONG/NORTH OF THE FRONT. VERY LARGE HAIL AND DAMAGING WINDS WILL BE THE PRIMARY CONCERNS FROM A SEVERE THUNDERSTORM PERSPECTIVE. OTHER CONCERN WILL BE POTENTIAL FOR SLOW MOVING THUNDERSTORMS AND BACK BUILDING ALONG/NORTH OF THE STALLED FRONT WHICH COMBINED WITH THE VERY MOIST/UNSTABLE AIR MASS COULD SUPPORT AN ELEVATED FLASH FLOOD POTENTIAL. IT IS STILL A LITTLE WAYS OUT...BUT I WOULD FEEL COMFORTABLE WITH A FLASH FLOOD WATCH IN THIS SITUATION IF MODELS REMAIN CONSISTENT AND COME INTO BETTER AGREEMENT ON FINER DETAILS. THURSDAY-SUNDAY...UPPER LEVEL WESTERLY FLOW TRANSITIONS TO THE SOUTHWEST BY NEXT WEEKEND AS UPPER LOW DEEPENS OVER THE SW US OR GREAT BASIN (DEPENDING ON MODEL/MODEL RUN). LOW LEVEL MOISTURE CONTINUES TO ADVECT INTO THE PLAINS FROM THE GULF OF MEXICO...AND PACIFIC MOISTURE MAY ALSO BEGIN TO ADVECT THROUGH THE SW FLOW ACROSS THE ROCKIES. PATTERN WILL CONTINUE TO FAVOR SHORTWAVE TROUGHS MOVING THROUGH THE PLAINS WITH THUNDERSTORM CHANCES THROUGH THE EXTENDED PERIOD. WITH SEASONAL HIGHS...UNSEASONAL DEWPOINTS...AND STEEP MID LEVEL LAPSE RATES CAPE VALUES SUPPORTIVE OF SEVERE THUNDERSTORMS WILL BE POSSIBLE EVERY AFTERNOON AND EVENING. I DECIDED AGAINST MAKING ANY MAJOR ADJUSTMENTS TO STARTING BLEND AS IT DOES A GOOD JOB OF MATCHING THE WET PATTERN WE ARE IN. && .AVIATION...(FOR THE 00Z TAFS THROUGH 00Z TUESDAY EVENING) ISSUED AT 526 PM MDT MON JUN 1 2015 VFR CONDITIONS ARE EXPECTED AT KGLD AND KMCK FOR THE NEXT 24 HOURS. SOME IFR CONDITIONS DUE TO STRATUS AND FOG ARE POSSIBLE AT KMCK EARLY FRIDAY MORNING. THERE IS A CHANCE OF THUNDERSTORMS AT KGLD THIS EVENING AND A SLIGHT CHANCE AT KMCK OVERNIGHT. && .GLD WATCHES/WARNINGS/ADVISORIES... KS...NONE. CO...NONE.
