What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Denver/Boulder, CO wrote its last area forecast discussion before this severe thunderstorm warning went out at Apr 22, 8:59 PM MDT, 58 minutes earlier.

Area forecast discussion, Apr 22, 8:59 PM MDT, 58 minutes before
Area Forecast Discussion
National Weather Service Denver/Boulder CO
859 PM MDT Fri Apr 22 2022

.UPDATE...
Issued at 859 PM MDT Fri Apr 22 2022

By 845 PM, the cold front has swept across all but the furthest
eastern zones, thus the RFW will be allowed to expire with RH
increasing quickly to 20-30 percent within an hour of FROPA in
most areas. In addition, the winds behind the front at much weaker
than what we saw into the early evening hours, so we have opted
to cancel the HWW a couple hours early though winds may still
gust to 40 mph for several more hours, particularly near the
foothills and across the far eastern plains. Winds will continue
to weaken all areas other than the higher mountains and foothills
above 8,000 ft. Latest CAMs show 50-60 kts cross barrier flow above
ridgetop tomorrow morning into midday. There is no stable layer
so that will limit mountain wave development, though there is a
critical layer (winds decrease quite a bit with heigh) above 500
mb which would support any mountain wave that develops. There is
also tremendous subsidence overhead as the trough swings across NE
Wyoming Saturday morning. This is a tricky forecast for winds
across the east slopes but believe the strongest winds will be
confined to the eastern foothills and not spread out below 6,000
ft elevation, though the favored wind corridor along CO-93 could
see gusts over 60 mph in the morning from 8 AM to Noon. The HRRR
is showing 80 mph gusts across the higher elevations of Boulder
County mid-morning tomorrow between 7-11 AM. The duration is
short and the areal coverage not great, thus for now have opted
not to hoist a High Wind Warning. The updated forecast reflects
this. Tomorrow afternoon with mixing and continued subsidence, a
bora-like event with strong NW winds and cold advection will make
it a windy afternoon across the entire area. Expect the strongest
gusts across the northern mountains and along the Wyoming border
across the northeast CO plains, where gusts in the 40-50 mph range
are expected. Gusts 30-40 mph are expected just about everywhere
else across the plains, Palmer Divide, and mountain valleys.

Two other slight adjustments were made based on the latest CAMs
and the fact that significant subsidence is expected. We removed
PoPs (they were very low to begin with) across most of the plains
other than along the WY border. Just too much downslope and
subsidence despite a little instability. We also dropped high
temps a couple degrees based on the latest guidance and the fact
that the cold advection on the backside of the trough, plus
convective cloud cover in the cold air would keep temps a little
cooler than originally expected. Highs across the plains should
still be upper 50s to around 60, with 30s in the mountain valleys.

Finally...there is some low-level moisture that worked back into
Sedgwick and Phillips counties. A few thunderstorms with strong
winds and marginally severe hail are possible between 10 PM and
midnight, but the window is narrow along the cold front and the
overall chances of any convection firing is probably less than 20
percent.

&&

.SHORT TERM...(This evening through Saturday)
Issued at 301 PM MDT Fri Apr 22 2022

...EXTREMELY CRITICAL FIRE WEATHER CONDITIONS CONTINUE THIS
AFTERNOON...

Forecast grids are in good shape this afternoon. The stronger
winds have been a little slower to arrive than forecast, though
surface obs in the past hour indicate several gusts above 40-45
mph in the plains, along with a few gusts above 60 mph at Limon
and the Cheesman RAWS. Guidance is insistent on stronger gusts
later this afternoon and evening as the 700mb flow increases to
45-55kt over the plains. Deep mixing... perhaps as high as 400mb
or so... should make it easy for at least some of this wind to
translate down to the surface over the next several hours. With
how dry and windy it already is, I see no reason to modify the
ongoing RFW or HWW products right now. We've been fairly lucky so
far this afternoon, but it cannot be stressed enough that
extremely critical fire conditions will be present across the
Foothills and all of the lower elevations through at least sunset.

The dryline should retreat west near the eastern CO border this
evening and overnight, and an isolated storm or two could fire
along this boundary in the evening. SPC's marginal/slight risk
over our far northeast corner is highly conditional but a couple
of storms can't be ruled out. Any storm that's able to survive and
take advantage of the warm/moist sector environment could produce
a strong wind gust or large hail, but the overall chances of
storms in our forecast area is fairly low. Additional showers will
also be possible over the far northeast as moisture wraps around
our departing surface low overnight.

The more difficult aspect of the forecast comes tonight and
tomorrow. It's looking increasingly likely that stronger winds
develop across the Front Range Foothills tonight, with two bursts
of strong gusts likely. The first comes this evening as the upper
trough axis crosses the area a couple of hours after sunset.
Ridgetop winds are near 50-60kt, and it wouldn't take much to get
a couple of 60-70mph gusts in the higher elevations as this moves
through. The more intense period of mountain wave winds comes late
tonight through Saturday morning. Ridgetop winds are again near
60kt and well aligned out of the west, with a clearly defined
critical layer located near 500-550mb. There should also be strong
mid-level subsidence that should contribute to some amplification
of the wave, and a few 75mph gusts are possible especially above
7000 feet in the morning.

Cooler temperatures will return for Saturday, though strong
synoptic scale winds should accompany the cool weather. The
strongest winds will be along the northern border from the
Cheyenne Ridge and into Sedgwick/Phillips county, where 700mb flow
is again near 50kt. With very strong subsidence through the
boundary layer, we should see at least a few strong gusts make it
to the surface there. Winds will be a touch weaker for the urban
corridor and eastern plains, but the wind will certainly still be
noticeable. A few showers will also be possible though
precipitation amounts are forecast to be very light.

Winter weather will also be a concern along and west of the
divide. Moisture will continue to slowly increase this afternoon
with snow showers developing after about 6pm, with more widespread
snow between midnight and noon. Accumulations will largely be
limited to areas above 9000 feet, though an inch or two is still
possible over the mountain parks. Will continue the Winter Weather
Advisories as planned with no major changes there.

.LONG TERM...(Saturday night through Friday)
Issued at 301 PM MDT Fri Apr 22 2022

We'll have drying with decreasing winds on Saturday night. Skies
should clear pretty well over the plains, though there may still
be some clouds near the northern border. The mountains will keep
the clouds, but the snow will be diminishing. There will still be
strong winds over the higher mountains, but the winds on the
plains should drop off fairly quickly after sunset.

Models continue to trend a little stronger/slower/colder with the
baggy south end of another shortwave that moves across Sunday
afternoon through Monday morning. This should generate clouds and
probably has enough of a combination of weak lift, moisture, and
instability for a good crop of showers over the mountains in the
afternoon and evening. It's hard to tell how much of this could
get east of the mountains. There's a period of nice upslope winds,
but the low levels also look pretty dry. Some low PoPs mainly
south of Denver seem appropriate. It could be cool enough in the
late evening for rain to change to snow as it is ending in areas
south of Denver, but any accumulation would be minimal and limited
to grassy areas. The mountain areas should mostly have light snow,
but there could be some heavier showers at the peak in the late
afternoon and evening. It appears this will be focused from the
I-70 corridor in the late afternoon southeast across Park county
in the evening.

Not much change to the forecast for next week. We'll still be cool
on Monday behind the shortwave, but it should clear pretty well.
Then it will be dry and warmer through the middle of the week.
Solutions vary about when and if it will be breezy, but the threat
of strong winds looks low until ahead of the trough late in the
week. There gets to be a bigger model spread for Thursday and
Friday, anywhere from hot and windy, to a low key severe weather
setup with weak upslope flow, to cooling into the 60s behind a
cold front. The one point of agreement is that the threat of
significant precipitation remains north of us.

&&

.AVIATION...(For the 00Z TAFS through 00Z Saturday evening)
Issued at 540 PM MDT Fri Apr 22 2022

Winds remain strong as expected this evening. For the most part
the strongest winds should have already occurred at the terminals,
with gradually decreasing winds expecting overnight. There will be
a wind shift to just south of due west around 8 PM (maybe 7 PM at
BJC). Expect the speeds to be lower with the west winds but still
gusting 25-30 kt until about midnight. Then after midnight the
winds at APA and DEN should be SW at 10-15 kts until 8 or 9 AM.
BJC could be a different story. Behind the cold front there is a
stable layer and critical layer of wind shear at 15 kft AGL, which
could generate a decent mountain wave. The winds from the mountain
wave may get as far east as BJC (but no further), which could
result in gusts over 40, maybe 50 kts between 3 AM and 10 AM. We
are keeping it out of the TAF for right now but will keep an eye
on the possibility. There will continue to be some BLDU at APA
and especially DEN this evening, but with the west wind shift
around 8 PM the dust should stay away after that.

On Saturday northwest winds will be the norm, and they will be
strong with sustained 20-25 kts and gusts to near 40 kts after 10
AM. By Saturday evening winds should slowly veer to the north and
weaken to around 15 kts with gusts over 25 kts. ILS conditions
are possible with scattered cumulus decks at around 050, maybe as
much as BKN by mid afternoon.

&&

.FIRE WEATHER...
Issued at 301 PM MDT Fri Apr 22 2022

Essentially every RAWS and ASOS station within the current Red
Flag Warning is experiencing critical fire weather conditions.
Several sites are now reporting humidities between 5 and 8% with
wind gusts continuing to slowly ramp up. Extremely critical
conditions are forecast to continue through sunset this evening
with humidities remaining below 10% for at least a few more hours.
At least a slight improvement in moisture is expected this evening
as a "cool front" shifts winds more to the west while humidities
climb into the upper teens across the Foothills and Plains.
Overnight humidity recovery is a concern across the Foothills and
urban corridor, especially given the lingering high wind threat
overnight into tomorrow. Saturday's conditions look a little
better. Winds will be northwesterly and still pretty strong, but
humidities will settle near 20% in the afternoon. Did ponder the
idea of additional Red Flag Warnings for a few spots but
ultimately will leave it be for now.

There will still be some wind on Sunday, but temperatures will be
cool. Monday will have lighter winds. There will be a warming and
drying trend through midweek. It will be breezy at times, so
conditions could be near Red Flag criteria, but strong winds are
not expected in this period. There is a chance of stronger winds
on Thursday or Friday, but there is much uncertainty about the
weather pattern on those days as another system approaches.

...EXTREME FIRE WEATHER CONDITIONS AND VERY WINDY TODAY FOR THE
LOWER ELEVATIONS AND THE EAST SLOPES OF THE FRONT RANGE FOOTHILLS...

This hazardous weather outlook is for northeast and north central
Colorado.

.DAY ONE...Today and Tonight

Extreme fire weather conditions will continue over the plains and
foothills through this evening. Very warm, dry, and windy weather
will make any new wildfire extremely difficult, if not impossible,
to control. The strong winds will also create blowing dust and
localized poor visibilities causing hazardous travel conditions
out on the plains.

A few thunderstorms are possible across the far northeast corner
of Colorado this evening. The storms could produce hail and
strong winds.

Snow is expected late this afternoon and tonight for the high
mountains, with scattered rain and snow showers in the foothills
and high valleys tonight and isolated rain showers over the
northeast plains.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday

Mountain areas will see rain and snow showers Saturday into
Saturday evening with 6 to 12 inches of snow in some areas, with
slick travel conditions over the higher mountain passes. At lower
elevations if will remain windy with gusts from 40 to 50 mph over
the plains. The foothills could see some strong winds Saturday
morning with a few gusts up to 70 mph.

On Sunday, a weak upper level system will bring more rain and
snow showers to the higher terrain, with a chance of rain showers
at lower elevations. The coming week will see warmer temperatures
along with dry and breezy conditions.

.SPOTTER INFORMATION STATEMENT...

Reports of high winds or damage will be appreciated.
