The episode as NWS GLD wrote it up.
Thunderstorms developed across western Kansas during the afternoon hours which led to dime to nickel size hail in Sharon Springs along with a 63 mph wind gust in Sherman county.
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 Jul 17, 3:15 PM MST, 11 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Goodland KS 415 PM MDT Wed Jul 17 2024 .KEY MESSAGES... - Thunderstorm chances continue through the end of the week with a risk for severe storms each day through Friday. - Temperatures remaining near normal through next week. - Locally heavy rainfall possible through Friday night. && .SHORT TERM /THROUGH FRIDAY NIGHT/... Issued at 1205 PM MDT Wed Jul 17 2024 17Z Water vapor imagery and RAP analysis indicated CWA under broad northwest flow with H5 ridge centered near the four corners region with trough centered over the northeast CONUS. PV analysis suggests at least 2 smaller disturbances moving over top of ridge to the west. At the surface broad and light easterly flow observed across area as surface ridge settles over the area. With dewpoints in the low 60s, already seeing CU fields develop, with storm initiation already occurring along weak convergence zone near KLIC. Primary short term concerns will focus on thunderstorm potential each afternoon and evening through Friday. As mentioned earlier, already seeing thunderstorm initiation on subtle convergent zone along Palmer Divide and expect this to continue on through the afternoon. While no major short wave trough is apparent upstream, inhibition looks rather weak allowing for several areas of thunderstorms to develop. The first will likely be along convergent zone/south of Interstate 70 in eastern Colorado, with storms moving east southeast through the afternoon hours. A second round of storms will likely initiate over the higher terrain and merge into more of an MCS in the evening hours. This will likely bring more widespread storms as it moves east into Kansas. Have doubts about how far east storms will make it as there is a rather sharp gradient in available instability and have opted to be a bit conservative on eastward progression. With instability around 1000 J/KG and fairly straight hodographs expect a few stronger storms early on, but think biggest threat will be organized cold pools/ damaging wind gusts. High precipitable water values, slow storm movement and high freezing levels support a heavy rain threat as well, but best potential does not seem to line up with where heavy rain has fallen recently. On Thursday, sfc ridge retreats to the east as trough strengthens over eastern Colorado. This will result in increasing southerly winds as well as increasing temperatures. While a similar upper level pattern will be in place during the afternoon, H7 temperatures will be several degrees C warmer than today resulting in stronger capping. Given the weak overall forcing, confidence in thunderstorm development not as high as today although threats will be similar to the last several days. Pattern continues on Friday although afternoon forcing looks to be stronger as weak cold front sweeps across the area. With more focused forcing along front, looks like Friday evening may be the best chance for rain across a large part of the area. && .LONG TERM /SATURDAY THROUGH WEDNESDAY/... Issued at 1233 PM MDT Wed Jul 17 2024 Medium range models in general agreement with the overall large scale pattern through the middle of next week as flow aloft becomes more northerly and rather weak as H5 ridge remains firmly in place across southwest CONUS and weak cut of low develops over the Central Plains. While there is a bit of uncertainty with exact track of this low, somewhat surprised that it is pretty well accounted for in the GEFS mean showing at least broad consensus between ensemble members. Net result will be a cooler and cloudy weekend with showers possible through Monday. With current data, does not appear to be a great severe weather threat with weak shear and limited available instability. && .AVIATION /00Z TAFS THROUGH 00Z FRIDAY/... Issued at 415 PM MDT Wed Jul 17 2024 KGLD...VFR conditions are currently forecast through the period. From taf issuance through about 06z, surface winds will be erratic due to thunderstorms in the area but generally from the south to southwest at speeds under 12kts. Outflow from nearby thunderstorms could reach 35kts and given slow storm motions visibilities could drop below VFR category due to heavy rainfall. After 07z, light and variable winds become southerly by late morning and increase in speed with gusts of 25 to 30kts. KMCK...VFR conditions are currently forecast through the period. An east to east-southeast wind up to 10kts is forecast from taf issuance through 14z. From 15z-20z, southeast winds under 11kts are forecast. After 21z, southeast winds gusting to 20kts or so are forecast. Presently, convection appears to remain well west and southwest of the terminal through the period. We will be watching for any thunderstorms well northwest of the terminal possibly making it toward the terminal late this evening. && .GLD WATCHES/WARNINGS/ADVISORIES... KS...None. CO...None.

A few severe thunderstorms are possible this afternoon and evening across much of the area, with the best chances across eastern Colorado. Hail up to the size of half dollar and strong wind gusts in excess of 60 mph are the primary threat with these storms. Locally heavy rain causing flash flooding is possible, but not expected to be widespread. .DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY... There is a marginal risk for severe storms Thursday afternoon and evening in northeast Colorado and along the Colorado and Kansas border area. Damaging wind gusts will be the primary hazard, as well as marginally severe hail. Severe storm chances continue on Friday afternoon and evening, with perhaps more widespread coverage possible. Damaging wind gusts will continue to be the primary hazard, but also some instances of large hail will be possible. .SPOTTER INFORMATION STATEMENT...
