The episode as NWS GJT wrote it up.
Showers and thunderstorms developed across western Colorado. Gusty outflow winds were the primary threat with activity, particularly the high based showers over northwest Colorado. Some gusts met high wind criteria in the Central Yampa River Basin.

Area Forecast Discussion
National Weather Service Grand Junction CO
405 PM MDT Fri Jun 17 2022
.SHORT TERM...(Tonight through Saturday night)
Issued at 359 PM MDT Fri Jun 17 2022
South-southwest flow continues today with temperatures roughly 10-15
degrees above normal. Surface moisture increased fairly quickly
early this morning as the trough over the Pacific Northwest begins
to come onshore. Showers with a few thunderstorms have been
scattered in coverage across much of the southern and high
elevations of the forecast area so far today. Expect this activity
to continue building northward with the increasing mid level
moisture. However, as has been previously mentioned, given the dry
surface conditions, even if we do have precipitation-producing
storms associated with lightning, fire concerns still remain. At
any rate, as the lower atmosphere continues to moisten, storm QPF
amounts will increase with a very small chance of flooding in prone
areas...such as burn scars and slot canyons. Don't expect flooding
to be a large concern with this multi-day rain event, but the risk
can't be ruled out. With the higher surface RHs, fire weather
doesn't look to be a concern at least through Saturday. Wind under
the jet max will continue to be an issue Saturday and beyond asthe
trough moves through the region.
.LONG TERM...(Sunday through Friday)
Issued at 359 PM MDT Fri Jun 17 2022
Bottom Line Up Front: Another breezy to windy period is in store
with low relative humidity and above normal temperatures through the
period. Temperatures will be running above normal with a few
showers possible for the high country over the weekend (mainly above
9000 feet).
Details: Flat ridge will be exiting to our east early Friday with
near-zonal flow setting up. This will bring the first ramping up of
winds into the breezy wording on Friday with humidity levels
dropping across our southern zones. Expect a return of elevated fire
weather concerns by the afternoon hours on Friday with very dry
conditions anticipated.
Flow starts to swing to the southwest late Friday and Saturday as a
long wave trough digs into the Pacific Northwest. Colder air pouring
into the Northern Great Basin and warmer conditions over the
southwest U.S. promise to place our forecast area into the cross
hairs of another very windy pattern as we push through the weekend
and into early next week. Models are hinting at a weak wave rotating
through on Saturday which could trigger high mountain showers (more
likely virga (rain evaporating before it hits the ground) which will
enhance the gust factor over the weekend. Valleys will remain dry
with humidity levels likely down in the 5 to 15 percent range, so
combined with the stronger winds, would anticipate a weekend with
high fire weather concerns. Will continue to monitor this trend.
As we arrive into the new work week, the long wave trough will be
deepening to our west with strong south to southwest flow moving in
for Monday, Tuesday and Wednesday. This appears to be a very windy
period for much of Eastern Utah and Western Colorado with continue
dry conditions and very warm temperatures. So fire concerns will
remain elevated until that trough moves overhead (which should be
late Wednesday/Thursday).
We will remain on the warm side of this new dynamic system through
this period with temperatures running a solid 10 to 20 degrees above
seasonal norms each day. If you have items that have not blow away
yet, nows the time to make sure they stick around through next week
as the winds will be blowing once again.
Quick recap, warm, windy and dry through the period with a few
showers over the high country possible over the weekend.

.AVIATION...(For the 18Z TAFS through 18Z Saturday afternoon)
Issued at 1148 AM MDT Fri Jun 17 2022
Showers and thunderstorms will develop and move north-northeast
this afternoon and continue into the overnight hours. Expect gusty
outflow winds to 50 mph, brief heavy rain and small hail with the
strongest storms. Local ILS CIGS will also be found in the
vicinity of showers/storms throughout the period. Potential for
heavy rain will increase on Saturday with more widespread shower
and thunderstorms activity expected.
&&
.FIRE WEATHER...
Issued at 359 PM MDT Fri Jun 17 2022
Critical fire weather conditions continue today. Dry/Mixed
thunderstorms will develop ahead of an approaching wave of
tropical moisture this afternoon/evening. Lightning and gusty
outflow winds will increase potential for new fire starts. Chances
for wetting rain increase substantially by Saturday as the
atmosphere saturates. However, lightning and gusty winds will
continue to pose threats through the remainder of the weekend,
espcially in eastern Utah where a watch is in effect Sunday.
The Sunday Watch in eastern Utah is at least partly dependent
upon the if/how much precipitation falls over those areas in the
next ~36 hours. Latest model trends have been drier, but RHs do
appear to be the limiting factor not only in Utah but across much
of the forecast area.
