The episode as NWS GJT wrote it up.
Abundant monsoon moisture fueled scattered to numerous showers and thunderstorms across western Colorado. The stronger storms produced gusty winds up to 58 mph across some of the lower valleys of west-central Colorado.
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 Grand Junction, CO wrote its last area forecast discussion before the first event at Jun 24, 2:39 PM MST, 43 minutes earlier.
Area Forecast Discussion National Weather Service Grand Junction CO 339 PM MDT Fri Jun 24 2022 .SHORT TERM...(Tonight through Saturday night) Issued at 339 PM MDT Fri Jun 24 2022 Showers and thunderstorms developed this morning as the mid-level trough discussed over the past several days began to track eastward across Utah. Satellite and RAP 500 mb analysis indicated the trough extended roughly along a KRWL to KCNY line 21Z. Storms continued to fire along and ahead of the trough where mid-level lift was maximized in the unstable airmass. As the previous shift pointed out, decent shear (30 to 40 kts) and CAPE values in excess of 1,000 J/kg suggest the potential for some organized storms. The main threat from the strongest cells is strong outflow wind gusts, though hail from 1/2 to 3/4 inches is also possible. In addition, the burn scar at Grizzly Creek is susceptible to rain rates of 0.60"/hour which have already been recorded with some storms. Therefore, the Flash Flood Watch will continue for Glenwood Canyon. Models were in good agreement with the progression of the trough and all indicated its axis will shift east of the Continental Divide by 00Z/Sat. Subsidence, advection of drier air and the stabilizing influence of diurnal cooling will bring an end to moist convection by midnight with clearing spreading west to east this evening. Precipitable water values decrease for Saturday falling to near 0.50" on average across the area. Reduced moisture across the region will lead to less widespread showers and thunderstorms with activity expected to be contained along the Continental Divide with the San Juan Mountains favored. Moist convection ends for most locations Saturday in response to diurnal cooling. However, nocturnal showers may continue over the southern San Juan Mountains and the Durango to Pagosa Springs corridor where moisture begins to deepen once again. Overnight lows will hover near normal while highs on Saturday climb by about 5 degrees for most locations in response to increased sunshine. .LONG TERM...(Sunday through Friday) Issued at 339 PM MDT Fri Jun 24 2022 Sunday is still looking like the most active day for the early week period as a ridge builds in over the Great Basin and the high over the Southern Plains drives a stream of moisture north into the Four Corners region. PWAT values of 0.6 to 0.8 inches are on tap for the day, plenty of juice to allow for widespread showers and thunderstorms to form off the higher terrain. Those above normal PWAT values also mean the threat of heavy rainfall remains. By Monday, the high over the Great Basin begins to shift east in response to a deep low off the Pacific Northwest. This drives a drier northwesterly flow over eastern Utah and western Colorado, cutting the tropical moisture plume at the southern border of Utah and Colorado. That said, forecast PWAT values are right around normal for this time of year, and there should be enough moisture still pooled over the area for afternoon convection to trigger once again that afternoon, though with less coverage compared to the day before. Tuesday looks to be the "driest" day of the period, though the word "dry" is maybe a bit misleading. The ridge axis will be moving overhead, and forecast PWATs will be at or maybe even slightly below average for the day, so convection will be at its most limited of the period. Still expect some widely scattered showers and storms to fire off the higher terrain through the afternoon, however. By Wednesday that low off the Pacific Northwest moves onshore along the Canadian border. While the Four Corners won't see any direct effects from it, the influence of this area of low pressure extends south along the West Coast and helps to nudge the Southern Plains high further southeast. Under these conditions, the monsoonal moisture tap turns on once more, with PWATs climbing back up to 150- 170% of normal by Wednesday night. With the increased moisture, shower and storm coverage will once again be on the increase for the end of the week. Long range models even hint that these conditions will remain into the weekend. Temperatures are expected to continue near normal through the period. && .AVIATION...(For the 18Z TAFS through 18Z Saturday afternoon) Issued at 1127 AM MDT Fri Jun 24 2022 As expected, convection has already begun across the northern half of the area. This will continue and become more widespread as the afternoon progresses, especially across the higher terrain of the San Juans. Main threats will be gusty, erratic winds and heavy downpours, although some hail will be possible as well. Outside of this, conditions will remain VFR for the next 24 hours, though KRIL/KEGE/KASE may see extended periods will CIGS below ILS breakpoints. Winds overnight will become light and terrain driven. Convection will be less widespread tomorrow afternoon, but is still expected to fire off the higher terrain. && .GJT WATCHES/WARNINGS/ADVISORIES...

Any stronger storms will be capable of producing strong winds, hail, frequent lightning and brief downpours. There is also the risk of flash flooding over the Grizzly Creek burn scar. A Flash Flood Watch is in effect. .DAYS TWO THROUGH SEVEN...Saturday through Thursday Monsoon moisture will continue to fuel daily showers and thunderstorms with varying coverage through the weekend and into next week. Showers and storms will favor the mountains and the adjacent high valleys. Similar to today, any stronger storms will be capable of producing strong winds, hail, frequent lightning and brief downpours. .SPOTTER INFORMATION STATEMENT... Spotter activation is needed due to the KGJX weather radar being down for maintenance. Please report any observations of strong thunderstorms producing hail, gusty winds, heavy rain, flash flooding, etc.
