The episode as NWS GLD wrote it up.
A couple severe wind gusts were reported with one of the thunderstorms in a southward moving line in Cheyenne County. The strongest wind gust reported was 64 MPH near Bird City. The thunderstorm winds were strong enough to cause blowing dust, which reduced the visibility to a quarter mile near Bird City.
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 6, 5:28 PM CST, 17 minutes earlier.
Area Forecast Discussion National Weather Service Goodland KS 528 PM MDT Thu Jul 6 2017 .SHORT TERM...(This evening through Friday) Issued at 200 PM MDT Thu Jul 6 2017 Scattered thunderstorms will develop in northeast Colorado later this afternoon near the Cheyenne Ridge and Palmer Divide, aided by a weak shortwave trough coming over the upper ridge. More isolated storms may also develop along a surface trough/cold front located roughly from Limon northeast to near McCook. Storms will move east this evening into the remainder of the area, but weakening as they enter a more stable airmass towards sunset. Best chance for severe storms will be in northeast Colorado early, with damaging wind and hail up to quarter size, given deeply mixed/inverted V soundings and weak instability. Activity should be done by 06z. Cold front will slowly sag south and west across the area, and by Friday afternoon be located near a Limon to Scott City line. Scattered thunderstorms will develop near the front, as well as in the post frontal upslope environment, aided again by weak shortwave energy coming over the persistent upper ridge. Instability will be stronger compared to today, up to 2000 j/kg, as will be the deep layer shear which will be around 40kts, both parameters maximized along/north of the surface front. As a result, may see more of a threat for severe storms, including a few supercells capable of producing large hail. LCLs are a little high for tornadoes, but with the surface boundary in the area and good directional shear, one cannot be totally ruled out. Temperatures will be slightly cooler behind the front, but still expecting lower to middle 90s, with upper 90s to lower 100s in far southwestern areas south of the front. .LONG TERM...(Friday night through Thursday) Issued at 139 PM MDT Thu Jul 6 2017 During the period the pattern still remains the same. A strong upper level ridge over the western U.S. is producing northwesterly winds aloft over the Tri-State region. The models are showing a series of strong shortwave troughs moving over the region during the onset of this period. The models are also showing strong vorticity advection associated with these shortwaves so the chances of showers and thunderstorms on Friday night are good. Saturday will see some lingering showers and thunderstorm in the region as these shortwaves continues to move out of the area. Sunday, the upper level ridge shifts more to the east and the upper level flow become more zonal over the northern U.S. by the end of the period. This will produce mostly dry conditions for the region from Sunday through the end of the period. The only question is Tuesday afternoon and night. The builder is calling for some showers and thunderstorms during this time. Looking at the models it is possible that a leeside trough is coming off the Front Range. Do not see any reasons to change anything at this time and we will look at the next couple of runs to see if it shows the same thing. Temperatures on Saturday will be close to normal and then they climb to well above normal for the rest of the period. Some areas will see high temperatures around and slightly above 100 by Monday. && .AVIATION...(For the 00Z TAFS through 00Z Friday evening) Issued at 528 PM MDT Thu Jul 6 2017 VFR conditions should prevail at both KGLD and KMCK terminals through the TAF period. Thunderstorm activity across southwest Nebraska and expanding into northwest Kansas will impact both terminals early in the TAF period with coverage decreasing later this evening. I couldn't rule out strong to severe thunderstorms with hail and winds 50kt or higher, but based on current coverage of stronger activity I am not confident enough to introduce winds stronger than 30kt at this time in TAFs. Another round of thunderstorms is possible Friday afternoon into the evening, but at this range and projected coverage I am holding off on introduction. Winds eventually shift to the east-southeast as a front moves into the region Friday morning, with prevailing winds 10-12kt possible. && .GLD WATCHES/WARNINGS/ADVISORIES... KS...NONE. CO...NONE.
