Isolated thunderstorms developed over the mountains and high valleys early in the day and then spread into portions of the plains, particularly the I-25 corridor. As these storms moved off the mountains, they produced isolated strong wind gusts along Highway 50 in Fremont and Pueblo counties.

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 Pueblo, CO wrote its last area forecast discussion before the first event at Jun 3, 10:19 AM MST, 2 hours 21 minutes earlier.
Area Forecast Discussion National Weather Service Pueblo CO 1119 AM MDT Wed Jun 3 2020 .UPDATE... Issued at 950 AM MDT Wed Jun 3 2020 Updated precipitation chances based on the latest model guidance. Expect showers and thunderstorms to develop by late morning into early afternoon over the Mountains, spreading east into the Plains, primarily north of Highway 50, with more isolated activity to the south. CAPE values are higher over the far Eastern Plains and one or two stronger storms may be possible over Kiowa County by late afternoon. Mozley && .SHORT TERM...(Today and tonight) Issued at 429 AM MDT Wed Jun 3 2020 Upper ridge remains in place for another day over srn CO, though air mass across the region will continue to dry, especially over the mountains. Expect another relatively down day for convection over most of the mountains and high valleys as PWAT values continue to fall, with mainly isolated tsra expected. Same story for the I-25 corridor as storms will be fairly isolated, though wly flow aloft increases enough to push any activity that does form over the mountains eastward onto the plains late in the day. Over the ern plains, weak forcing as upper wave slides by to the north and diffuse surface boundary provides some low level convergence, leading to perhaps an upturn in tsra near the KS border by late afternoon. SWODY1 marginal severe risk dips down and includes a portion of the far eastern plains, though better forcing and shear will lie farther north in ne CO/nw KS, where mid/upper level flow is stronger. Not much change in heights/temps aloft today, and expect max temps within a few degf of yesterday's readings. Overnight, convection ends fairly quickly, with any strong storms on the plains shifting into KS during the evening. Overnight min temps will end up little changed from the past several days, with clearing skies and light winds by early Thu morning. .LONG TERM...(Thursday through Tuesday) Issued at 429 AM MDT Wed Jun 3 2020 Thursday-Friday...Upper level ridging looks to build across the Rockies through the day Friday, as eastern Pacific energy is progged to move onshore across the southern California Coast and slowly lift out into the Desert Southwest. Models continue to indicate a slow drying of the mid level moisture with dry line pushing east across the far southeast plains and into western Kansas and Oklahoma on Thursday, though there will likely be enough residual moisture to support isolated to scattered higher based storms over and near the higher terrain both Thursday and Friday afternoon and early evening. There are some differences on how fast low level moisture mixes out across the area, with current SPC Day 2 Outlook indicating a small sliver of the far southeast plains in the marginal risk of severe storms on Thursday. Warm air under the building ridge will help boost temperatures to above seasonal levels, with highs pushing into the 90s to around the century mark across the plains, warmest on Friday. Highs look to be in the the 70s and 80s across the high mountain valleys and higher terrain both days, with highs in the 50s and 60s at the peaks. Friday night-Saturday night...Differences remain on location and speed of the eastern Pacific energy as it lifts out across the Great Basin and Rockies, with the GFS faster and further south and west with said energy, as compared to the ECMWF and Canadian runs. Either way, the best lift and moisture associated with this system looks to be across the western half of the district on Saturday, with chance and likely pops spreading across the higher terrain through the day. Again, depending on timing and location of this passing system, there could be critical fire weather conditions across portions of southern Colorado on Saturday, with gusty southern winds possible through the afternoon and evening hours. Temperatures on Saturday will cool slightly from Friday's levels, as cooler air aloft pushes across the area ahead of the passing system. Sunday-Tuesday...More eastern Pacific energy is progged to dig across the Great Basin Sunday and Monday, with moderate to strong southwest flow aloft progged across the Rockies. This will lead to more widespread critical fire weather days across the region, with mainly dry, breezy to windy conditions combined with above seasonal temperatures. There are differences on timing and location of this system as it translates across the Rockies, though current grids have chances of precipitation for mainly northern portions of the state, along with cooler temperatures areawide on Tuesday. && .AVIATION...(For the 18Z TAFS through 18Z Thursday afternoon) Issued at 1116 AM MDT Wed Jun 3 2020 Showers and thunderstorms will be possible at all three terminals this afternoon and evening. KCOS will have the greatest chances at seeing a thunderstorm. Reduced VIS and CIGS along with gusty outflow winds to near 40 kts are possible with passing storms. Otherwise, VFR conditions are anticipated through Thursday afternoon. Mozley && .PUB WATCHES/WARNINGS/ADVISORIES... NONE. && UPDATE...MOZLEY SHORT TERM...PETERSEN LONG TERM...MW AVIATION...MOZLEY

A few storms will also develop over the eastern plains and Interstate 25 corridor by mid-afternoon, with storms lingering into the evening near the Kansas border. A few strong to severe storms will be possible this afternoon and evening over Kiowa, Prowers and Bent Counties, with winds over 60 mph and hail up to the size of quarters. Over the remainder of the area, storms today may produce hail up to dime size, wind gusts to 50 mph, frequent lightning and brief heavy rainfall. If a heavier thunderstorms moves over a burn scar, flash flooding will be possible. .DAYS TWO THROUGH SEVEN...Thursday through Tuesday Afternoon and evening thunderstorms will remain possible Thursday through Saturday, with the best coverage expected over the higher terrain on Saturday. On Thursday, there will be chances for strong to severe storms across eastern portions of Kiowa, Prowers and Baca Counties, with large hail up to the size of quarters and damaging wind gusts the main severe storm threat. There will also be a threat of flash flooding, if storms form or move across the Spring, Decker, Junkins, and Hayden Pass burn scars. Critical fire weather conditions will be possible across portions of southern Colorado Saturday through Monday, as breezy to windy conditions develop across the region into early next week. Over the mountains, temperatures are expected to remain warm for the next several days, with overnight lows staying above freezing. This will enhance the melting of the higher elevation snow pack, with increased flows and speeds expected in area rivers and streams. .SPOTTER INFORMATION STATEMENT... Weather conditions that meet reporting criteria for spotters will be possible across all of south central and southeast Colorado this afternoon and evening. 88/88
