Area Forecast Discussion
National Weather Service Pueblo CO
512 AM MDT Fri Apr 24 2026

.KEY MESSAGES...

- Critical fire weather conditions expected for much of the area
  today, with more spotty conditions anticipated for Saturday.

- Chances for precipitation increase this weekend and into early
  next week. Snow likely for the mountain peaks, while the
  plains should see some showers and isolated thunderstorms.

&&

.SHORT TERM /THROUGH TONIGHT/...
Issued at 1234 AM MDT Fri Apr 24 2026

Currently...Broad upper low center was located in Canada just north
of MT, producing widespread westerly flow aloft across Colorado.
Cold front passage earlier this evening has pushed all the way
across the eastern plains, with widespread 40s and 50s being
reported as of 10 PM. Overnight lows, under clearing skies, are
forecast to dip into the 20s to around 30F for the high valleys, and
30s across the plains.

Today and Tonight...The upper low to the north is forecast to move
very little through the short term, but a shortwave rotating around
the low will swing across the Intermountain West and Great Basin
today, shifting the flow aloft to a slightly more west-southwest
direction while also tightening the pressure gradient. Fire weather
info will be addressed down below, but ongoing highlights for today
look good. There may be a few showers over the central mts this
afternoon as the shortwave approaches, but for the most part expect
another very dry day with high temps in the 60s for the high
valleys, and 70s to near 80F for the plains. Overnight low temps
tonight should be a bit more mild due to some mt clouds and brisk w-
sw flow, with mid 20s to mid 30s for the high valleys, and 30s to
lower 40s for the plains.

&&

.LONG TERM /SATURDAY THROUGH THURSDAY/...
Issued at 1234 AM MDT Fri Apr 24 2026

Saturday...The forecast calls for some changes in the overall
pattern starting Saturday. First, the upper low to the north will
drop a cold front south into CO late Friday night, which will then
surge across the Palmer Divide and set up across the eastern plains
Sat morning. Meanwhile, an upper longwave trough starts to take form
over the western US as another upper low pushes onshore across CA,
which will shift the flow aloft to a more southwest direction across
the Four Corners. In turn, southwest surface winds will increase
across the higher terrain and southern portions of the forecast
area, and at some point across the eastern plains the incoming
frontal boundary will meet the increasing southwest winds and
stagnate. This will lead to high fire danger for portions of the
area, mentioned below, and will be highly dependent on where that
boundary sets up. Plan on highs in the 60s for the high valleys, and
mid 60s to mid 70s for the plains. The southwest flow aloft
increases through the evening, and finally taps into some Pacific
moisture that is expected to bring some beneficial new snow to the
mts. At this point snowfall amounts look to be up to 2 inches for
the central mts, and 1 to 3 inches for the southwest mts through Sat
night. Further east across the plains, scattered rain showers are
forecast. Overnight lows should be on the mild side due to increased
cloud cover, with readings in the 30s for the high valleys, and mid
30s to lower 40s for the plains.

Sunday and Monday...The upper pattern gets pretty messy Sunday and
Monday as a couple of strong shortwaves cross the region, bringing
additional mt snow and continued convection chances for the lower
elevations. Current forecast grids paint an additional 6-8 inches of
new snow for the peaks of the Continental Divide, while the rest of
the higher terrain sees 2-4 inches. Some of the long range models
are hinting at a more northerly track for all this activity, which
would result in a similar shift of precip amounts, so fingers
crossed that those solutions are incorrect. Sunday may get somewhat
warm across the eastern plains during the afternoon with readings of
around 80F for the SW corner, but most of the plains will see mid
60s to mid 70s, and 50s for the high valleys. Monday will be about 5
degrees cooler.

Tuesday through Thursday...Current grids indicate a mainly dry and
warm day for Tue, then unsettled Wed and Thu with widespread precip
chances and much cooler temps as a strong cold front pushes in Wed
night. Moore

.AVIATION /12Z TAFS THROUGH 12Z SATURDAY/...
Issued at 510 AM MDT Fri Apr 24 2026

VFR conditions at all three terminals (KALS, KCOS, KPUB)
through the next 24 hours. Gusty southerly winds are forecast at
each terminal this afternoon, with gusts 25 to 30 kts. An
increase in mid and high level clouds is forecast for late
afternoon into the overnight period. A cold front will impact
KCOS and KPUB tonight into Saturday morning with gusty winds
possible.

&&

.FIRE WEATHER...
Issued at 1234 AM MDT Fri Apr 24 2026

Very dry conditions and receptive fuels remain.

Critical fire weather conditions expected today as southwest winds
at 10 to 20 mph, with gusts as high as 40 mph, develop through the
afternoon and combine with single digit RH levels. Red Flag Warning
remains in effect for much of the area today from 11 AM until 9 PM
tonight.

High fire danger is expected to continue for portions of the
district on Saturday, and will be highly dependent on where the
gusty southwest winds are realized and not negated by the advancing
cold front. Therefore, went with a Fire Weather Watch for Fire Zones
224, 229 and 230, which covers the San Luis Valley, and those
wind-prone gap flow areas in the vicinity of Walsenburg and
Trinidad. RH levels should dip down into the 10-15 percent
range, with southwest winds gusting up to 30-40 mph. Did not
include Zones 220 nor 222 at this time due to lack of widespread
coverage, but they may need to be included by following shifts.

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

.DAY ONE...Today and Tonight

Critical fire weather conditions are expected today for much of the
area, with a Red Flag Warning in place from 11 AM this morning until
9 PM this evening. West winds are forecast to increase to 10 to 20
mph with gusts as high as 40 mph, and minimum relative humidity
levels dropping into the single digits. Please refrain from all
outdoor activities that could start a fire.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday

High fire danger continues to be a threat for portions of the area
on Saturday, with very dry conditions and receptive fuels remaining
in place. Gusty southwest winds are forecast across the San Luis
Valley, and wind-prone gap flow areas in the vicinity of Walsenburg
and Trinidad.

Shower chances then increase area-wide over the weekend into early
next week as a weather system moves across the region, with the
greatest chance for precipitation occurring along the Continental
Divide Saturday night through Monday. Snow accumulation is likely
over the higher terrain, with a risk of isolated thunderstorms for
portions of the plains. The main threat at this time with any storms
that do develop will be wind gusts to 50 mph, and cloud to ground
lightning.

.SPOTTER INFORMATION STATEMENT...

Weather spotters will not be needed today or tonight.
