In the evening hours of the 11th, an east-west line of showers formed in northeast Colorado and moved east. As these showers moved into Yuma County, CO, winds gusted out ahead of these showers, producing a 59 MPH gust south of Wray, CO.

Area Forecast Discussion National Weather Service Goodland KS 820 PM MDT Sat Jun 11 2022 .UPDATE... Issued at 820 PM MDT Sat Jun 11 2022 Somewhat complex forecast update for the remainder of tonight. Thunderstorms just west of the forecast area have fallen apart once they enter the forecast area. One storm west of the area had a wind gust to 49 mph. The 00z NAM has a 700mb theta-e axis north of the interstate at present time which is where storms are approaching from the west. DCAPE values in this area around 1500 J/KG supporting damaging wind gusts. By 06z the NAM has about 2K Joules of CAPE at 2km with no CIN over far eastern Colorado with the instability axis is flowing into it from the east. Both it and the HRRR show precipitation developing or moving in from the west. As this area of instability moves east and along I-70 by 09z DCAPE values increase somewhat with both NAM/HRRR showing a small MCS type feature with potentially damaging wind gusts the primary hazard. By 12z, this feature should be out of the area. HRRR wind gusts from the latest 01z run are a bit lower compared to the 00z run but still suggest gusts up to 70 mph or so. HRRR also continuing to show a heat burst signature featuring temperatures just ahead of the stronger wind gusts reaching the lower 90s with relative humidity falling into the 15 to 20 percent range. The timing of this potential heat burst is similar to climatology for the area. So for the update I've started with extending the slight chance pops, following the NAM and HRRR to an extent. Once confidence increases in the event underway pops would be increased. && .SHORT TERM...(This evening through Tuesday) Issued at 225 PM MDT Sat Jun 11 2022 Upper ridge centered over the southern plains today will gradually shift eastward on Sunday and Monday with a southwesterly flow aloft through Tuesday. Embedded shortwaves will support a chance for thunderstorms Sunday afternoon and evening, and once again Tuesday evening. Temperatures will be much above normal through the period with record high temperatures possible each day. First chances for thunderstorms will be on Sunday. Appears storms will initiate along subtle surface convergence boundary which will separate dew points in the 50s to the north from the 30s and 40s to the south. It will lie roughly along a Yuma to Russell Springs line at 20-21z when models forecast initiation to occur. Storms will then move northeast through the afternoon and evening, exiting the area around 03z Sunday night. Environment is forecast to be moderately unstable northeast of the boundary with deep layer shear of around 35 kts. Models suggest discrete cells initially will quickly form into a cluster as they move northeast. SPC has Slight Risk across the area which seems reasonable in this set up. Wind and hail will be the main hazards, with deep layer shear limiting potential for supercells/tornadoes. High temperatures will once again top out around 100 and lows Sunday night in the 60s to lower 70s. Monday will be hot, breezy and dry, although cannot totally rule out an isolated high based storm in the afternoon that produces little if any precipitation. Breezy to windy southwest winds gusting to around 45 mph will introduce additional downslope warming to an already hot set up, and record breaking temperatures well into the 100s are expected, might see a few locations in typically hot areas around Hill City reach 110. Apparent temperatures will be a bit less with low humidity, topping out in the 90s in western areas and lower 100s in eastern areas, where a heat advisory may be needed. Cold front will move through late Monday night with winds shifting to northwest. Low temperatures will range from the upper 50s behind the front in Colorado to the middle 70s ahead of it in north central Kansas. Front should make its way through the entire forecast area by Tuesday morning, but stall out in southern areas midday before trying to retreat northward Tuesday afternoon. Will get a break from the extreme heat on Tuesday, but still see highs ranging from the upper 80s in Colorado to the upper 90s around Hill City. Upper trough will swing through Tuesday night with best chances for showers and thunderstorms north of Interstate 70 where stationary front may be located. Deep layer shear will be quite strong, perhaps too strong as instability is forecast to be weak and limited to a narrow area along/north of the front. As a result, severe risk appears to be fairly low. Low temperatures Tuesday night will range from the upper 40s to upper 50s, slightly below normal. .LONG TERM...(Sunday night through Saturday) Issued at 228 PM MDT Sat Jun 11 2022 The long term period will be dry with seasonable temperatures on Wednesday that rise to well above average values again by Friday and Saturday. Southwest flow aloft becomes zonal and weaker as the upper low pressure area moves into the Great Lakes region and high pressure expands across the Plains as a ridge amplifies and moves across the Rockies and High Plains by late Thursday. The upper ridge continues east over the central continental U.S. on Friday and into the Mississippi Valley region by late Saturday as the incoming west coast trough rides up the back side of the ridge. Cooler air behind a cold front remains across the central High Plains region on Wednesday and begins modifying on Thursday as near surface flow turns back to the south as a warm front lifts across the region. High temperatures will be near average for this time of year with highs on Wednesday in the 80s and lows mainly in the 50s. Temperatures continue to rise with gusty south to southwest near surface winds aiding in the warming and drying of the airmass Friday and Saturday in advance of the surface trough deepening along the Front Range ahead of the incoming upper trough. Highs by Saturday are expected to be back up in the middle 90s to lower 100s with lows in the 60s to lower 70s. && .AVIATION...(For the 00Z TAFS through 00Z Sunday evening) Issued at 455 PM MDT Sat Jun 11 2022 KGLD...VFR conditions are expected through the period. Winds will be all over the compass for the next 24 hours. Tonight, east winds up to 10kts at taf issuance will veer to the south then southwest at similar speeds. On Sunday, winds should be from the north up to 10kts, veering to the east then southeast through the day. Thunderstorms are possible this evening in the 03z-06z timeframe. Given the isolated nature and low confidence that any of them would directly impact the terminal will be keeping them out of the forecast at this time. KMCK...VFR conditions are expected through the period. Winds tonight generally from the northeast and east up to 10kts becoming light and variable after midnight. On Sunday, northeast winds up to 10kts in the morning should veer to the east then southeast through the afternoon at similar speeds. No precipitation is expected at this time. && .GLD WATCHES/WARNINGS/ADVISORIES... KS...NONE. CO...NONE. NE...NONE. && UPDATE...99 SHORT TERM...024 LONG TERM...LOCKHART AVIATION...99

Heat indices will be at or a few degrees above 100 degrees east of Highway 83 for Sunday and Monday afternoons.
