.SHORT TERM /THROUGH TONIGHT/...
Issued at 1259 AM MDT Sat Jun 20 2026

Today...

An upper-level shortwave trough will pass over our area today,
bringing with it much more active weather and several concerns for
the forecast.

Over the eastern plains, a lee trough will develop at the surface
during the afternoon. This will couple with hot temperatures (mid-
90s to around 100F) and a southerly wind that should bring some
higher dewpoints to the CO/KS border. This, along with the advancing
shortwave. will provide ample ingredients for severe thunderstorms
during the afternoon and evening hours. Specifics on storm mode,
longevity, and most likely impacts will depend on a few factors,
namely the timing of the upper wave passing over and how much
moisture actually makes it back onto the eastern plains of Colorado.
As usual, forecast models are somewhat inconsistent with moisture
content at the surface, and therefore available instability. That
being said, even the HRRR, which tends to underdo dewpoints, still
has mid-50s by early in the afternoon across our far eastern
counties. The more aggressive models, such as the NAM Nest, have
dewpoints hovering right around 60, which is more than enough to get
storms to form and intensify. Across the CAMs, CAPE looks to quickly
increase the further east you go, with 800-1000 J/kg over I-25 by
mid-afternoon and anywhere from 1500-2000 J/kg along our eastern
border. Bulk shear should be anywhere between 35-45 knots as well.
In all, looking at storm potential for today into this evening, all
severe hazards are on the table, including large hail, gusty and
potentially damaging winds, heavy rainfall, and a lower-end threat
for isolated tornadoes.

That being said, severe storms will only be possible where storms
actually manage to form. With quickly decreasing moisture closer to
the mountains, coverage over the I-25 corridor will be isolated,
with only a few smaller storms possible. Anything that makes it
further east will quickly intensify, with better coverage closer to
the KS border. This will be one of those "all or nothing" sort of
days, where storms may initially struggle to form in our area,
especially if the upper wave comes in later than expected, but
anything that manages to fire should be pretty strong.

Meanwhile, critical fire weather conditions are expected across the
entirety of our higher terrain, clear out to the I-25 corridor and
some adjacent areas. This is due to the mentioned lack of moisture
further to the west, coupled with dry, hot conditions and gusty
southwest winds with plenty of downsloping. A Red Flag Warning
remains in effect for most of the area, 11am-10pm.

&&

.LONG TERM /SUNDAY THROUGH FRIDAY/...
Issued at 1259 AM MDT Sat Jun 20 2026

Hot again on Sunday, and generally drier. Highs will be similar to
today's, if a few degrees lower. Meanwhile, west winds continue
aloft, pushing most of the moisture away from our CWA, though gusts
should be less frequent. Critical fire weather conditions are still
expected over the higher terrain and some of the mountain valleys.

Sunday Night into Monday, another shortwave disturbance will glance
by to our north, sending a weak front across the eastern plains. The
influx of higher-dewpoints, coupled with the boundary, will likely
net us a few hours of thunderstorms during the evening hours and
into the early overnight. These storms will likely line up on the
boundary, becoming strong to severe with wind gusts being the main
impact concern.

Moving into next week, long-term models remain mostly consistent in
the evolution of the synoptic pattern. A high pressure center will
set up south of Colorado, with westerly flow aloft into our region
and a few shortwaves passing over throughout the week. Over the
higher terrain, expect critical fire weather conditions almost every
afternoon, with temperatures remaining a bit above average and
intermittent gusty winds. Over the eastern plains, the passing
shortwaves will provide lift while ESE surface winds bring in
moisture. Strong to severe thunderstorms are anticipated each
afternoon into evening, primarily close to the Kansas border.

The pattern breaks down later in the week, with models becoming much
less consistent on our next incoming system.

&&

.AVIATION /12Z TAFS THROUGH 12Z SUNDAY/...
Issued at 538 AM MDT Sat Jun 20 2026

VFR conditions expected at COS, PUB and ALS over the next
24 hours. Winds to be generally light through the morning.
Stronger winds will develop around midday before becoming gusty
south southwest 15-30kt by 18Z. Most convective storms will be
east of the terminals, with severe storms expected across the
southeast plains. There is a chance of these storms creating
downburst winds that reach PUB, yet forecast confidence remains
too low to include that in the forecast.

&&

.FIRE WEATHER...
Issued at 1259 AM MDT Sat Jun 20 2026

Still expecting a very active week, fire weather-wise, across the
region.

Today: Critical fire weather conditions become much more widespread
across the region today. Above average temperatures will coincide
with gusty west-southwest winds and plenty of downsloping, leading
to RH values in the teens to single digits over the mountains, and
only slightly higher further east. A Red Flag Warning remains in
effect for most of our forecast area, 11am to 10pm.

Sunday Onwards: Hot temperatures and breezy west winds will continue
throughout the week. The mountains will see continued dry surface
conditions and intermittent wind gusts, leading to more critical
fire weather conditions each afternoon, mainly over the central
mountains but spreading towards the San Luis Valley and the Upper
Arkansas at times as well.

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

.DAY ONE...Today and Tonight

Isolated to scattered thunderstorms are expected this afternoon into
this evening. Chances for storms will be highest over the far
eastern plains, with odds decreasing further to the west. Storms
that form are expected to intensify, becoming strong to severe. Main
impact concerns will be damaging winds 70 to 80 mph, hail of 2 to 2
and a half inches in diameter, and a few isolated tornadoes.

.DAYS TWO THROUGH SEVEN...Sunday through Thursday

On Sunday, isolated to scattered storms will be possible mainly
north of highway 50. Some may become strong to severe, producing
outflow winds to 70 mph and small hail.

From Monday through late week, showers and thunderstorms will be
possible over the plains each day. A persistent upslope pattern
combined with several weak disturbances in the northwesterly flow
aloft will allow for these storms to become strong to severe. Large
hail, damaging winds and a tornado or two will be possible through
this period.

Over the mountains, it will remain quite warm and very dry, and fire
weather concerns will be high through this period over the higher
terrain.

.SPOTTER INFORMATION STATEMENT...

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