Severe storms that had developed in northern Colorado moved east into northeastern Colorado. As these storms moved closer to the Colorado and Kansas/Nebraska borders, they began decaying.

The episode as NWS GLD wrote it up.
Severe storms that had developed in northern Colorado moved east into northeastern Colorado. As these storms moved closer to the Colorado and Kansas/Nebraska borders, they began decaying. As these storms decayed, a heat burst occurred which caused severe winds which led to a hay shed being tossed around 100 yards.

NWS Goodland, KS wrote its last area forecast discussion before the first event at Jul 12, 3:53 PM MST, 5 hours 2 minutes earlier.
Area Forecast Discussion National Weather Service Goodland KS 453 PM MDT Tue Jul 12 2022 .SHORT TERM...(This evening through Wednesday) Issued at 219 PM MDT Tue Jul 12 2022 19z Water Vapor indicated CWA on eastern fringe of 594 dm H5 ridge centered over the 4 corners region. RAP dynamic tropopause analysis indicated embedded short wave trough centered over the GLD area and was slowly moving east south-east out of the area. At the surface, trough was developing across eastern Colorado with 1019mb high centered near KEAR. Visible satellite was showing area of cumulus developing in area of return flow in northeast Colorado. Main forecast concerns will center around small precip chances through tomorrow afternoon, followed by magnitude of the warmup and associated hazards on Tuesday. Tonight...With previously mentioned short wave trough departing the area, large scale forcing for ascent will quickly diminish. That may limit initation of thunderstorms over the CWA, but overall subsidence likely not strong enough to inhibit thunderstorms from rolling off the higher terrain during the evening. Given the position of the available instability axis, do not think storms will be able to advance past the KS/CO state line. Considerable uncertainty exists with respect to increasing LLJ allowing storms to continue past 06z and am currently think it is unlikely that storms will continue into the overnight hours, at least in an organized sense. Wednesday-Wednesday Night. H5 ridge will move east through the period, with region getting closer to center/more removed from influence of passing disturbances. While large scale forcing will be missing, current forecast soundings and convective temperatures suggest heating will be sufficient to erode convective inhibition. Lack of a focusing mechanism leads me to think coverage will be spotty and storms strongly tied to the diurnal heating cycle. Otherwise expect to see temperatures several degrees warmer than today with upper 90s and low 100s becoming established. Dewpoints will likely drop to the 40s across western zones by late afternoon, forcing humidities into the 15-20 percent range. However winds will generally be lighter in this area and am not anticipating need for any fire highlights. .LONG TERM...(Thursday through Tuesday) Issued at 144 PM MDT Tue Jul 12 2022 Early in the long term, the ridge axis shifts eastward and amplifies, resulting in near-record high temperatures and near-heat advisory criteria in northeastern portions of the area to close out the work week. RH values in the mid teens on Thursday have potential for increased fire weather concerns mainly along and west of KS Hwy 27, though winds are only expected to be in the mid teens to low 20s (knots). Embedded disturbances within the ridge allow afternoon/evening thunderstorm chances to remain in the forecast Thursday through Saturday. The main threat with any storms continues to be strong, damaging winds with inverted v profile forecast soundings. Temperatures will be in the upper 90s to low 100s over the weekend before the ridge amplifies again, bringing drier conditions Sunday onward. Another day to monitor for fire weather conditions will be Monday as RH values drop into the teens and forecast wind gusts are in the upper teens to low 20s. && .AVIATION...(For the 00Z TAFS through 00Z Wednesday evening) Issued at 452 PM MDT Tue Jul 12 2022 For KGLD & KMCK... VFR conditions are expected through the TAF period. Winds will remain roughly from the south through the period around 10-12 kts. && .GLD WATCHES/WARNINGS/ADVISORIES... KS...NONE. CO...NONE.
