The episode as NWS GLD wrote it up.
In the afternoon of the fifth, a cluster of storms formed in eastern Colorado. As the storms progressed to the southeast, they formed into more of a line. This led to 70 MPH winds and hail up to 1.75 inches across parts of far eastern Colorado.
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 5, 2:57 PM MST, 1 hour 41 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Goodland KS 357 PM MDT Thu Jun 5 2025 .KEY MESSAGES... - Strong to severe storms are forecast for today with hail up to two inches, damaging winds around 65 mph and perhaps a brief tornado. The favored area is mainly along and west of Highway 25; with the best chances across eastern Colorado. - Another round of strong to severe storms is forecast Friday mainly along and south of a Yuma to Gove line. Damaging winds and large hail are the main threats. Isolated instances of county road flooding may be possible especially for areas that see repeated rounds of storms. - Below normal temperatures through the end of the week, but warming back up to normal and above normal by the weekend and into next week. && .SHORT TERM /THROUGH FRIDAY NIGHT/... Issued at 1140 AM MDT Thu Jun 5 2025 The main focus for the short term period will be for strong to severe storms this afternoon and evening and again Friday. Starting with today. Shortwaves are forecast to move off of the Rockies and onto the Plains this afternoon. Clearing is already ongoing across the Colorado Plains and should continue to move towards the state line through the afternoon. The main question for the day will be how far east will the clearing make it as thick stratus and rain showers are forecast to be ongoing across portions of NW Kansas and SW Nebraska. The further east clouds can erode then that is how far east the severe threat can expand. There are two areas of storm development and potentially a third: 1) Storms should develop across northern Colorado and move to the southeast with the right mover motion towards Yuma and Kit Carson county moving in around 5-6pm MT. Supercell structures should be the dominant mode initially but with straight line hodographs in place do think some splitting of cells where a cluster may end up developing. Hazards with this look to be hail to golf balls, damaging winds to 65 mph and perhaps some landspout potential early on and some secondary threat as storm interactions begin occurring as splitting occurs. Cloud cover will dictate how far east the severe threat goes with this cluster. Confidence is fairly high in this scenario as a consistent signal has been seen for the past 24-36 hours. 2)Another shortwave moving across the southern Rockies in southern Colorado is forecast to yield some development mainly south of Highway 40 but the greater coverage should remain south of the area. There is however some potential for storm development across Cheyenne (CO), Greeley and Wichita counties as some clearing is seen moving in from SE Colorado; so if storms form then hail around 2 inches in diameter, damaging winds and a tornado as some better curvature in the low levels is seen. Low to medium confidence in this area for severe as it will be dependent on the shortwave ejection location but would potentially have the higher impacts; timing would be around 3p-11pm MT for this area. 3) The third area is for sure the more conditional threat. A surface convergence boundary/differential heating boundary may end up setting up roughly along Highway 27 south of Interstate 70 which would be the focus for an earlier start time around 1-2pm MT with all hazards on the table as they move east and become more surface based. This is for sure the least likely scenario for today as most guidance other than the RRFS has backed off of it from what was seen yesterday afternoon. I am however noticing a very subtle spin in in the clouds just west of Morgan county Colorado as of 10am MT so will be interesting to see if this yields this scenario or not. No matter which scenario pans out moderate to occasionally heavy rain is forecast to follow the storms which may lead to some localized flooding potential especially for locales that see storms as PWATS are forecast to be ranging from 1-1.3 inches; however storm motions should be fast enough that flooding shouldn't be a major impact. Some fog may develop overnight into early Friday morning due to a freshly saturated boundary layer and would become more likely if rain were to move out quicker. Friday, another shortwave is forecast to move off of the Front Range during the afternoon hours as an MCS looks to form with damaging winds the main hazard and potentially some hail with any stronger updrafts within the MCS; guidance then suggests another disturbance as well during the evening hours with severe again possible. At this time the favored area for severe weather looks to be confined to areas along and south of a Yuma county to Gove county line. Flooding may be more possible Friday with two rounds of potentially heavy rainfall and with the round this evening as well. However if discrete cells can maintain themselves then the hail threat would increase as well. High temperatures for Friday are currently forecast to be a little warmer than today in the mid 60s to low 70s. && .LONG TERM /SATURDAY THROUGH THURSDAY/... Issued at 1223 PM MDT Thu Jun 5 2025 Saturday, ridging begins to develop across the western CONUS which will be the start of a warming trend for the area as high temperatures are currently forecast to rebound in to the mid 80s across the area. The forecast for the most part is dry for Saturday but there is a 10-20% chance Norton and Graham county may get skirted with a passing shower as a weak disturbance moves across north central Kansas. Sunday at this time appears to be a bit more active as a low pressure system develops across the northern Plains which moves a cold front back through the area. Showers and storms are currently forecast to develop along the front with severe weather possible during the afternoon and evening hours. There does remain some discrepancies with the overall placement of the low and timing of the front. A slower cold frontal passage would support an increased severe weather potential for the area. Into the start of the next week, we remain in the NW flow pattern but not seeing any indications at this time of any disturbances in the flow so the forecast will remain dry for now. High temperatures are forecast to remain in the upper 70s to low 80s across much of the area. Troughing then does look to return towards the middle portion of the week with the potential for our active pattern to continue with severe weather chances possible. && .AVIATION /00Z TAFS THROUGH 00Z FRIDAY/... Issued at 341 PM MDT Thu Jun 5 2025 MVFR to IFR conditions are forecast to continue for each terminals although a very brief period of VFR for KGLD ahead of storms. Will maintain the PROB30 for KGLD this still appears to be the most likely for thunderstorms to impact the terminal. Low stratus is again forecast to develop tonight along with some fog potential; there is potential for dense fog especially if rainfall moves out quicker. This potential at this time looks to favor KGLD. IFR conditions are forecast to continue through mid morning before MVFR conditions return. Showers and storms are then forecast to move back in towards the end of the period or just slightly after. Due to uncertainties with exact time will leave out of the TAF for now. && .GLD WATCHES/WARNINGS/ADVISORIES... KS...None. CO...None.
