.SHORT TERM /THROUGH FRIDAY/...
Issued at 219 PM MDT Thu Aug 7 2025

Temperatures early this afternoon were already in the 100s over most
of the lower Ark Rvr valley over the plains. with 90s over most
other region of the plains. Valleys were in he 70s and 80s. A few
showers were noted over the region, mainly across the Raton Mesa and
the La Garitas.

For the rest of today, no significant changes from earlier fcst as
temps will be well into the lower 100s across a good part of the
plains with highs pushing 90 over the San Luis valley. Winds over
the region were noticeably stronger as measured synoptic winds over
the CONTDVD were gusting in the 45 to 60 mph range. Winds on the
plains were gusty in places with 20 to 30 mph winds up in the El
Paso county region and over the far eastern plains. Mtn areas were
near red flag criteria most places (winds are meeting criteria but
RH values were still in the 15 to 20 percent range. As the day
progresses winds are anticipated to keep up and RH values will
continue to lower as dryer air advects into the region. Heat
advisories remain in effect for the urban areas and lower Ark River
valley in the plains. Showers today will generally be high based with
little if any rainfall reaching the ground. Some localized strong
gusty winds can't be ruled out.

Tomorrow, it temps look identical to today but winds are expected to
be a few miles per hour higher. Red Flag conditions will continue
over parts of the region tomorrow. Note that even meteorological
conditions for extreme fire behavior will occur nearly all areas,
Fuels are not conducive, and thus red flag warnings are only in
effect for certain areas (Teller county is an area where it will be
hot and dry today and tomorrow, but Fuels are not conducive for fire
spread, and thus not red flag warnings). With hot temperatures
continuing over the plains, heat advisories will continue over the
urban areas and lower Ark Rvr valley area of the plains. Similar to
today, isolated high based showers will be possible once gain for
tomorrow. \/Hodanish

.LONG TERM /FRIDAY NIGHT THROUGH THURSDAY/...
Issued at 219 PM MDT Thu Aug 7 2025

Friday night-Monday...Models remain consistent with a pattern
change as passing Northern Tier wave Friday night, and secondary
energy digging across the Northern Rockies Saturday night into
Sunday morning develops a cooler northwest flow pattern, as
upper level ridging builds back across the Desert Southwest and
into the Great Basin through early next week. Saturday will
feature cooler and moist upslope flow across eastern Colorado,
supporting temperatures some 5-15F cooler than Friday and
chances of afternoon and evening showers and storms over and
near the higher terrain into the southeast plains. Further west,
the drier and warmer airmass will remain, with a few isolated
high based storms expected along with temperatures only slightly
cooler than Friday. The drier and breezy conditions will
support critical fire weather conditions across the Central Mtns
and into the San Luis Valley once again on Saturday, and will
likely need a Fire Wx Watch for these areas with the next
forecast. The secondary energy digging across the Northern
Rockies Saturday night will bring in the coolest temperatures of
the week for Sunday and Monday, with continued daily chances of
showers and storms, with the best coverage across the Eastern
Mtns and plains on Sunday.

Tuesday-Thursday...Upper ridging progged to build back and flatten
across the Rockies once again, with temperatures warming back to
above seasonal levels areawide. Ensemble data supports drier air with
PWATs below normal across the area through the middle of week with a
slow increase in available moisture and daily shower and storm chances
into the end of the next work week.

.AVIATION /06Z TAFS THROUGH 06Z SATURDAY/...
Issued at 1104 PM MDT Thu Aug 7 2025

VFR conditions are expected at KALS, KCOS, and KPUB through 24
hours.  Winds will decrease overnight as mid-level clouds begin to
move in across the area. For Friday, generally dry conditions with
hot temperatures across the region. Gusty west winds around 25 knots
or so set in over all three terminals, and there is a very low
chance for showers and virga late afternoon into early evening,
though the coverage looks too isolated to include any precipitation
in the TAFs at this time. Near the end of this forecast period,
around 03-05Z or so, a front will move in from the north to both
KCOS and KPUB, with gusty winds out of the north 25 knots or so.
