.SHORT TERM /THROUGH TONIGHT/...
Issued at 1243 PM MDT Tue Sep 8 2026

The main concern in the short term is the threat of showers and
thunderstorms, some strong with heavy rain, extending for the El
Paso/N Pueblo area eastward out to Kiowa county. Strong storms will
be possible in this above mentioned area, but the heavier rain
threat will likely be over the greater Kiowa county region late this
evening.

First, SPC has pushed the marginal westward to E Pueblo/E El Paso
county area eastward. This looks reasonable as a band of CAPE and
some shear are noted over this region later today. Secondly, the
CAMS have been showing some rather impressive 1 hour rainfall
amounts this evening over the far eastern plains, mainly in the
greater Kiowa county region. The guidance has been pretty persistent
on keeping these rather high qpf values run and run. Have bumped up
the QPF over this region and we have issued a mesographics
describing the threat for late this afternoon into the evening hours.

Another area of showers and storms is expected to occur mainly this
afternoon and early evening along the CO/NM-OK border areas.

Over the remainder of the region, the convective activity will be
more isolated. Although I cannot rule out some heavy rain over the
Aspen Acres burn scar, the probability is too low for a flash flood
watch.

Tomorrow...Seasonable temperatures are expected this day and not
expecting too much during the afternoon time period. The best chance
of precip prior to 6 pm tomorrow will be over the southern Sangres.

Tomorrow night...and interesting scenario develops as the guidance
has rather high pops over all of the southeastern plains tomorrow
evening and tomorrow night. forcing for this precip is associated
with a short wave in the developing WNW flow aloft developing over
the region. The NBM POP numbers looked a bit overdone to me, and
have decreased these values to scattered values for most of the
evening /overnight time period.

The moisture late tomorrow over the AA burn scar may be of higher
quality, and later shifts may need to issue a flash flood watch for
the AA Burn scar for the Wed afternoon/evening time period.

.LONG TERM /WEDNESDAY THROUGH TUESDAY/...
Issued at 1243 PM MDT Tue Sep 8 2026

Thursday, drier air is forecast to move into the interior sections
and it will likely be dry over the higher terrain. the best chance
of any showers will be over the far southeastern plains during the
late afternoon and evening time period. Temperatures will be
seasonable this day. Marginal critical fire weather conditions will
be possible over the interior mtns due to single digit min RH
values and breezy conditions.

Friday is expected to be mainly dry and much warmer, with mid 90s
most of plains and mid 80s valleys. It will be much drier over the
interior  and fire weather concerns will continua over the interior
mtns (Although RH values will be a bit higher than Thursdays values).

Weekend...Saturday will be cooler than Sunday (Mid 80s vs Low 90s).
Scattered storms are expected each day in the mtns with isolated
over the plains.

For early next week, statistical guidance still shows quite a bit of
variability, but overall it shows a cooling trend with a better
chance of showers and thunderstorms over the region. The
variability is likely due in part to the timing of a cool front
which is forecast to come down the plains during the ~Tuesday-ish
time frame. /Hodanish

.AVIATION /00Z TAFS THROUGH 00Z THURSDAY/...
Issued at 440 PM MDT Tue Sep 8 2026

Showers and thunderstorms will develop along the front range and
push eastward with a high probability of affecting KCOS and KPUB
between 00z and 03z. Gusty outflow winds up to 50 kts, heavy
rainfall with MVFR to IFR vis will be possible with +RA. There
is a low chance for small hail at KCOS. Otherwise KALS will see
variable evening cloudiness with the possibility of VCSH with
gusty outflow winds, though odds are low. Thunderstorms will
push east across the plains overnight and another cold front
will push southward through the plains bringing gusty north
winds up to 25 to 30 kts through the morning at KCOS and KPUB.
Winds will swing around from the east in the afternoon at both
terminals. Thunderstorms will redevelop Wednesday afternoon but
are expected to stay south of highway 50 and unlikely to affect
the terminals. KALS will stay dry with some scattered VFR
clouds. -KT
