The episode as NWS GLD wrote it up.
In the late evening of the 28th, a line of thunderstorms moved south-southeast from the Colorado, Wyoming, Nebraska border. In Kansas, up to 1.75 inch diameter hail and multiple reports of wind damage were reported. These storms lasted into the early morning of the 29th. There were also some storms that fired ahead of this main line in the early evening that produced severe hail.
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 28, 5:13 PM CST, 2 hours 2 minutes earlier.
Area Forecast Discussion National Weather Service Goodland KS 513 PM MDT Wed Jun 28 2023 .SHORT TERM...(This evening through Thursday Night) Issued at 1255 PM MDT Wed Jun 28 2023 The remainder of this afternoon is forecasted to have most of the area warm into the 90's with locations south and east of a line from Tribune to Norton potentially reaching the upper 90's. Parts of Eastern Colorado have been slower to warm with temperatures still in the 70's. Models also underestimated the dewpoints in Eastern Colorado which have still been in the mid 60's as of noon instead of the mid to low 50's. With the high amounts of moisture remaining, there is a threat for a few storms this afternoon and evening with a surface boundary south of the area and a potential upper shortwave moving through. However, similar to yesterday, the big limiting factor will be potential capping. The cap could be stronger over Western portions of the area where temperatures may not warm as much as guidance was suggesting due to early morning fog and higher moisture available over the area. This will affect the potential for storms later this evening for areas near and north of the Tri-State border. Guidance has suggested that storms could form in Northeastern Colorado (ahead of the shortwave and along the higher terrain) and move east across northern portions of the Tri-State area. But if the cap remains in place, any initial development would struggle to form and then maintain itself into the area. Otherwise, it would be possible for a few supercells to move across and produce damaging hail and winds for counties generally along the Nebraska border. The other chance area is for counties in Northwestern Kansas along and south of I-70 this afternoon and evening. Satellite shows a line of clouds along a surface boundary around Southwestern Kansas and Southeastern Colorado. If storms form along or ahead of the boundary, they may be able to move northeast into parts of the Tri-State area. Given the current position of the boundary, storms would likely need to fire closer Pueblo given the mean motion to the northeast would mean anything starting further south and east may miss the area. Tonight, skies will remain partly cloudy and winds shift to out of the east. With the easterly winds, fog will be possible depending on how moist the area remains and how much clouds hinder cooling. Lows will remain the 60's for most of the area. If fog does develop, may need to watch for some patchy dense fog. Guidance is suggesting that the favored area would be similar to last night, east of Highway 83. For tomorrow, slightly cooler temperatures are forecasted with some slight cold air advection aloft lowering our 850mb temperatures in the 20's. Some additional cloud cover and lingering moist conditions will also keep temperatures slightly cooler. How much cooler is a bit uncertain given the lack of an air mass change. But temperatures in the 80's and 90's remain likely with the warmer temperatures generally east of Highway 83. If cooler air did advect in, most of the area would stay in the 80's. Storms are forecasted to move through the area again tomorrow afternoon and evening as the upper trough that has been over the west moves closer to the area. With the increased synoptic forcing of both the upper trough and a surface low just south of the area, higher chances and coverage for storms are expected. There could be severe weather as well with large hail and damaging wind gusts given MLCAPE around 1000-2500 J/KG, effective shear around 45-50 kts and DCAPE greater than 1200 J/KG. Storm should move from west to east across the area as the trough moves through from west to east. The hail threat will likely be highest with initial storm development in Eastern Colorado and then slowly transition to more of a linear storm mode and wind threat. .LONG TERM...(Friday through Wednesday) Issued at 1251 PM MDT Wed Jun 28 2023 12Z Friday the area is under southwesterly flow aloft with the upper trough axis centered over the Four Corners region. This will gradually move east, and bring shower and storm chances to the area. The WPC has included the Tri-State Area in a marginal risk for excessive rainfall on Friday. Afternoon high temperatures are forecast to be in the middle 70s to middle 80s with overnight low temperatures in the middle 50s to lower 60s. Into Saturday, high pressure builds over the western CONUS while the upper trough over the plains progresses eastward, leaving us under northwesterly flow aloft. We'll see some continued storm chances as the trough begins to exit the area. Temperatures continue in the middle 70s to middle 80s for highs and middle 50s to lower 60s for lows. Drier weather is anticipated to start the week as the upper ridge moves overhead. Weak disturbances within the flow however may bring some spotty afternoon-evening showers/storms. Temperatures will start to warm back up into the middle 80s to lower 90s Sunday, then middle 80s to middle 90s Monday with overnight lows in the middle 50s to middle 60s. A trough dipping south into the northern CONUS around Tuesday- Wednesday, July 4th-5th may provide better focus for storms. Temperatures climb into the middle 80s to middle 90s for the 4th and upper 70s to lower 90s on Wednesday. Lows will be in the mid to upper 50s to mid to upper 60s. && .AVIATION...(For the 00Z TAFS through 00Z Thursday evening) Issued at 508 PM MDT Wed Jun 28 2023 VFR conditions are anticipated to continue through the majority of the TAF period with the exception for some stratus or patchy fog developing near KGLD around 11Z; currently anticipating MVFR ceilings and visibilities but its not out of the realm of possibility for dense fog to form similar to this morning. As for KMCK, some guidance has suggested the cluster of severe storms making its way into SW Nebraska and potentially impacting the terminal around 06Z. Will monitor newer guidance through the evening, and will issue an amendment if confidence increases enough that the terminal will be impacted. && .GLD WATCHES/WARNINGS/ADVISORIES... KS...NONE.
