Around midnight a northward moving thunderstorm produced wind gusts strong enough to blow power poles down in both Yuma and Washington Counties. After the storm moved through, the unseasonably strong winds continued for a third day in a row over East Central Colorado.

The episode as NWS GLD wrote it up.
Around midnight a northward moving thunderstorm produced wind gusts strong enough to blow power poles down in both Yuma and Washington Counties. After the storm moved through, the unseasonably strong winds continued for a third day in a row over East Central Colorado. What makes this more unusual is the high winds started after midnight, which does not even occur when winds of this magnitude are more common. The peak high wind gust was in Cheyenne County of 83 MPH near Firstview.
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 7, 10:49 PM MST, 1 hour 26 minutes earlier.
Area Forecast Discussion National Weather Service Goodland KS 1149 PM MDT Sun Jun 7 2020 .UPDATE... Issued at 904 PM MDT Sun Jun 7 2020 Have allowed the Red Flag Warning and High Wind Warning to expire. Relative Humidity values are recovering above Red Flag criteria as the temperatures cool following sunset. Winds are still on track to diminish slowly overnight with sustained wind speeds decreasing to 25-35 mph and gusts dropping to between 35 and 45 mph. Expect a lull in wind speeds around sunrise before winds shift to the northwest and become gusty again into Monday afternoon. && .SHORT TERM...(This evening through Monday) Issued at 250 PM MDT Sun Jun 7 2020 With the Tri-State area situated beneath a tightening height gradient between a deep upper level trough over the Western CONUS and a deep upper level ridge over the MS River Valley -- active/ dynamic weather will persist. Well above normal temperatures, deep mixing, and strengthening southerly flow aloft will maintain (1) dangerous travel conditions assoc/w high winds (and areas of blowing dust) across the entire Tri-State area and (2) extremely critical fire weather conditions in Eastern Colorado. Winds and fire weather conditions will improve with loss of heating this evening. .LONG TERM...(Monday night through Sunday) Issued at 222 PM MDT Sun Jun 7 2020 Primary forecast concerns will center around strong short wave trough that will move into the region on Monday night and slowly work its way across Kansas on Tuesday. Concerns for thunderstorms will come in two phases, the first would be possibility for surface based convection initiating along frontal boundary across northeastern CWA (such as McCook and Norton areas). Models mixed on whether cap can be overcome in this area, but should it occur strong shear indicated by 350-400 m2/s2 0-3km SRH and 1000-2000 j/kg of CAPE would easily support supercells, although storm motion would have them quickly move out of the area. Should this scenario occur, very large hail and a tornado or two are possible. Overnight as system approaches the area, expect second round of thunderstorms to develop to the north of the cold front in area of large scale ascent. Instability will diminish through the night, but given strong speed shear above frontal zone, elevated hail storms would be possible through the night although storms will not be as strong as those in the early evening. Otherwise as system slowly moves across the area expect storms to gradually transition to rain showers and much cooler air to work into region. While thunderstorms will diminish, strong northerly winds will accompany the passage of this trough. Models not giving much consistency with respect to what vertical profile will look like by Tuesday afternoon, but all point to winds averaging close to 40 kts in the mixed layer which could approach high wind warning criteria. Considered a watch, but uncertainty just too high at this point given vertical profile concerns. Tuesday Night-Sunday...H5 ridge will build over the region through the rest of the period as another trough becomes established over the west coast. This amplifying pattern will lead to another hot and dry period with temperatures increasing each day, reaching the 90s by next weekend. There are some signals a cold front could back into area providing some relief Saturday and Sunday, but given the overall pattern think most likely scenario would be the continued warming trend. && .AVIATION...(For the 06Z TAFS through 06Z Monday night) Issued at 1116 PM MDT Sun Jun 7 2020 VFR conditions are expected at MCK and GLD through the 00Z TAF period. Gusty south southeast winds will be noted through much of the night at MCK and GLD with LLWS due to south winds near 50kts through much of the night. Gusty winds and LLWS subside by early Monday morning around 12Z with south winds becoming variable through the day as the prefrontal trough moves across the region in advance of the cold front that expected through the region around 04Z Monday evening. Gusty north northeast winds are expected behind the front. && .GLD WATCHES/WARNINGS/ADVISORIES... KS...NONE. CO...NONE.

Localized reductions in visibility remain possible overnight with gusty winds causing areas of blowing dust. .DAYS TWO THROUGH SEVEN...MONDAY THROUGH SUNDAY... Severe thunderstorms are possible Monday afternoon and into the overnight hours, primarily east of a Benkelman, Nebraska to Leoti, Kansas line. The first round of storms will occur between 5 pm CDT and 9 pm CDT mainly east of a line from Trenton, Nebraska to Hoxie, Kansas. Storms that form here may produce large hail greater than golf ball size and a brief tornado. Thunderstorms will continue Monday night and will expand in coverage with the threat for severe weather diminishing. A cold front will bring strong northerly winds of 30 to 40 mph with gusts over 50 mph on Tuesday. Winds will be strongest near the Kansas and Colorado border region. Except for the cooler and more humid conditions with the passage of the cold front on Tuesday, elevated fire weather conditions may persist throughout the remainder of the week and into next weekend across portions of far eastern Colorado. .SPOTTER INFORMATION STATEMENT... Spotter activation is not expected tonight.
