Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this flash flood warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

.SHORT TERM /THROUGH TONIGHT/...
Issued at 152 AM MDT Sat Jul 25 2026

Current water vapor imagery and upper air analysis has a large
upper ridge in place across the southern High Plains and into the
Rockies, with an 598DM high in place across the Central Rockies
at this time. Water vapor and GOES Blended Total Water Vapor imagery
has PWATS running between 100-125 percent of normal under the upper
high, with PWATs of 150-200 percent of normal currently across the
Great Basin. Regional radars early this morning still have a few
spotty showers ongoing over and near the higher terrain, with a
lone thunderstorm across the southern Sangre de Cristo mtns as of
midnight.

For today and tonight, models keep the center of the upper high in
across the Central Rockies, keeping weak, mainly westerly flow aloft
in place across the region. This, along with enough moisture in place
under the high, and strong summer solar heating, all support another
round of afternoon showers and thunderstorms developing over the higher
terrain through the late morning and continuing through the late
afternoon, with showers and storms spreading east across the high
mountain valleys and immediate adjacent plains, through the afternoon
and evening. The best coverage will be along and west of the ContDvd,
though slow movement of storms will continue to pose a the threat for
flash flooding, especially for the recent burn areas of Lake, Pueblo and
Custer counties. Hot temperatures will also be a concern, with temperatures
expected to quickly warm into the 90s through the late morning across
the plains, and then topping out in the lower 100s. With slowly cooling
temperatures through the overnight hours, we did add Otero, Bent and
Prowers counties to the Heat Advisory for today. While temperatures will
be hot, current records are also rather high for today, 94F for ALS in
2023, 98F for COS in 2003 and 107F for PUB in 2003.

&&

.LONG TERM /SUNDAY THROUGH FRIDAY/...
Issued at 152 AM MDT Sat Jul 25 2026

A similar forecast remains in place for Sunday, as the center of the
upper high slides a tad south and east across the southeast plains.
This will bring another few degrees of warming to southeast Colorado,
with highs expected on the upper 90s to possibly 109F across the far
southeast plains. With that said, we have added Crowley and Baca counties
to the current Heat Advisory in place for Sunday. Could also see a few
records fall on Sunday, with current record highs being 91F for ALS in
2023, 97F for COS in 1953, and 103F for PUB in 2023. As for convection,
model data continues to indicate enough residual moisture in place, to
work with strong solar heating to support scattered showers and storms
over the higher terrain once again on Sunday. Weak westerly flow will
help to push storms east across the high mtn valleys and immediate adjacent
plains through the afternoon and evening hours. Again, will need to watch
for potential flash flooding for recent burn areas.

For next week, weak westerly flow will continue to increase monsoonal
moisture across all of south central and southeast Colorado, leading to a
slow cooling and wetting trend across the area. The southeast plains will
at least get some chances of showers and storms through the middle and end
of next week, with abundant moisture in place. The daily rounds of slow
moving showers and storms will raise flash flooding concerns over the burn
scars, as well as areas that develop saturated soils due to the increase
in daily storms.

&&

.AVIATION /18Z TAFS THROUGH 18Z SUNDAY/...
Issued at 1120 AM MDT Sat Jul 25 2026

FR conditions are anticipated during the next 24 hours at all
3 taf sites, KPUB, KALS and KCOS. Winds will be diurnally
driven. There will be a slight chance of a shower/-tsra at or in
the vicinity of KCOS late in the afternoon.

This hazardous weather outlook is for portions of central...east
central...south central and southeast Colorado.

.DAY ONE...This Afternoon and Tonight

100 degree plus readings are expected over most of the plains
today. The 100 degree readings will likely occur generally below
5000 feet elevation. If you will be outside today make sure you
stay well hydrated. Heat advisories are in effect for the highway
50 corridor from Canon City to the Kansas border, and also across
El Paso county.

Showers and thunderstorms are expected this afternoon and evening
over the higher terrain...mainly above 6000 feet elevation. The
storms will be likely across the Continental Divide region and
scattered over the remainder of the mountains. Over the San Luis
Valley storms will be isolated. The storms over the mountains will
have the potential to cause heavy rain. Any heavy rain over the
burn scars will have the potential to cause flash flooding.

.DAYS TWO THROUGH SEVEN...Sunday through Friday

Hot temperatures will continue and expand on Sunday, with high
temperatures in the upper 90s to possibly 109F across across the
southeast plains, where another Heat Advisory is in place from
10 am to 9 pm mdt.

Daily showers and thunderstorms are expected to continue and expand
through the early to middle of next week. The best coverage of storms
will remain over and near the higher terrain, leading to increasing
concerns of flash flooding for area burn scars, as well as areas that
can develop saturated soils due to daily rounds of moderate to heavy
rainfall.

.SPOTTER INFORMATION STATEMENT...

Weather conditions that meet reporting criteria for spotters will
be possible over portions of the region.
