.SHORT TERM /Today and tonight/...
Issued at 114 PM MDT Sun Jun21 2026

Rest of today,

Latest obs indicate moisture over the plains is hanging in as dwpts
remained in the 50 or above below 7500 feet. The deeper moisture wes
note over the far eastern plains where 60 dwpts were noted. Storms
were already beginning to form over NE Colorado, and with the NW
flow aloft any rotating storm will have the propensity to move to
the right of the mean flow, although the hodographs today are pretty
straight so we may get left and right splits once the convection
matures. Overall given the location of the sfc trough over NE CO,
the greatest strong/svr storm potential will be over are far eastern
plains late this afternoon and evening.

Later tonight, guidance continues to indicate a cluster of storms
will back-build into the southeast plains as a 700 mb trough
propagates over the region. These storms are forecast to become most
prevalent after midnight and affect the southeast plains into the
early morning hours.

Red Flag conditions were occurring over several region of the
interior valleys and mountains early this afternoon, and this will
continue into the early evening hours.

&&

.LONG TERM /TOMORROW THROUGH SATURDAY/...
Issued at 114 PM MDT Sun Jun 21 2026

Weather looks to be quite active this upcoming week as a favorable
pattern for severe storms develops over the region. NW mid level
moderate flow will continue through most of the week and several
disturbances will move over the region in this flow. Additionally,
upslope flow will be in place. The combinations of the NW Flow aloft
and the surface upslope will set up a favorable shear pattern, along
with sufficient CAPE, for organized severe storms to develop in the
afternoon and evening hours. Given the NW flow, storms will have the
potential to affect the I-25 corridor cities if right turning
supercells develop vicinity of the mtn/plains interface. The
severe weather threat will likely last into Thursday. By Friday,
flow aloft finally weakens and the threat for organized
convection will decrease.

Over the higher terrain, it will remain hot, dry and breezy at times
as a modest jet will be over the region. This will keep fire danger
high over the mtns and valleys, A Red Flag warning is in effect
tomorrow and additional warnings will likely be needed through
Wednesday for the interior mtns and valleys.

Later in the week, guidance indicated that mid level moisture moving
up from the tropical Pacific will move over S California and then
into COlorado, This should bring an increasing chance of precip to
the mtns starting Thursday and lasting into Saturday. Likewise, we
should hopefully start to see some rain over the higher terrain by
later in the week.

It looks to dry out by Sunday all areas as a rather anonymous mid
level trough develops over the Pacific NW and rather strong flow
(and very warm temps aloft) move over the region.

&&

.AVIATION /18Z TAFS THROUGH 18Z MONDAY/...
Issued at 1114 AM MDT Sun Jun 21 2026

VFR conditions are anticipated during the next 24 hours at all 3 taf
sites, KPUB, KALS and KCOS. Diurnal flow will continue this
afternoon but a boundary will push through KCOS and KPUB around
00 UTC and this will bring breezy NE winds to the two taf
sites. into the early evening hours. There will also be a chance
of a late night shower at KPUB.

.FIRE WEATHER...
Issued at 114 PM MDT Sun Jun 21 2026

Critical fire weather conditions are likely to continue over the
interior mountains and valleys Today through Wednesday, and then
again next Sunday and Monday. Red Flag warnings are already in effect
for tomorrow for the interior and additional highlights will likely
be needed for the same regions through mid week.

combination of northwesterly mid level flow, sufficient
instability, and several disturbances in the flow aloft will allow
for scattered thunderstorm to develop each day. With sufficient
shear over the region. the storms will have to propensity to
become severe, producing large hail. damaging winds and a tornado
or two. Given that the flow aloft is northwest may allow for
severe thunderstorm activity to affect the larger population

times, and critical fire weather conditions will be likely
Monday, Tuesday and Wednesday over the interior mountains and
