Key Messages:

1) Warm and breezy with critical fire weather conditions expected across
   the plains on Saturday.

2) Widespread snow and blowing Saturday night and Sunday across the higher
   terrain along the Continental Divide

3) Windy to very windy conditions expected across all of south central and
   southeast Colorado on Sunday, leading to high fire danger and possible
   critical fire weather conditions.

Tonight-Saturday...Model data remains in good agreement of increasing
west to southwest flow aloft across the region through the day tomorrow,
as a strong eastern Pacific storm system, moving onshore across the Pacific
Northwest Coast this afternoon, remains progged to translate into the Great
Basin region through the day Saturday. With the increasing west to southwest
flow and expected deep mixing, will see breezy westerly winds of 15 to 25 mph
with gusts of 35 mph across most of southeast Colorado, and combined with dry
air in place and rhs around 10 percent, the current Red Flag Warning from
11 am to 7 pm still remains on track. Good mixing and the downslope flow will
also help to keep overnight lows on the mild side, especially in the banana
belt along and west of the I-25 Corridor, with highs on Saturday expected to
be above seasonal levels in the 70s and 80s across the eastern plains, and
mainly in the 50s and 60s across the higher terrain, save for 30s and 40s
at the peaks.

Saturday night-Sunday night...Models continue to be in good agreement with
the movement of Great Basin system across northwestern Colorado and
into the Northern Rockies, with a strong jet core translating across
south central and southeast Colorado through the day Sunday. This will
bring windy to very windy conditions to the region, with the potential
for strong downslope winds developing across the southern Sangre de Cristo
Mtns late Saturday Night and spreading out into the lower elevations of
the southern I-25 Corridor Sunday morning, as mtn top winds approach
50 to 60 kts, along with period of neutral shear before winds aloft
increase later Sunday morning and afternoon. This increasing flow aloft
will also bring strong and gusty winds to the rest of the higher terrain
and the southeast plains on Sunday, with the potential of seeing gusts of
50 to 60 mph continuing through the day Sunday, strongest across the plains
along and south of the Highway 50 Corridor, as the upper system and associated
cold front aloft translates across the south central and southeast Colorado.
This will also lead to possible critical fire weather conditions once again,
especially across the southeast plains, where the warmest temperatures are
expected, along with possible areas of reduced visibilities in blowing dust.
With that said, we have issued  a high wind watch for the southern Sangres and
the southern I-25 Corridor for late Saturday night and Sunday, with the potential
of a high wind watch/warning being extended further east on Sunday. We have also
issued a Fire Weather Watch for the southeast Plains on Sunday, which could also
be expanded if necessary, as with the expected strong winds, fire danger will be
high across much of the area.

In addition, the strong west to southwest upslope flow and increasing moisture
associated with the passing system, will bring widespread precipitation to the
higher terrain, especially along and west of the ContDvd, where the first
significant snowfall of the season. While total snowfall amounts continue to
vary between advisory and warning criteria, the snow combined with the strong
winds will create hazardous travel conditions across the higher mountain passes
of the ContDvd late Saturday night and through the day on Sunday, and being the
first winter weather evening of the season, we issued a Winter Storm Watch from
Saturday evening through Sunday night for the eastern San Juan, La Garita and eastern
Sawatch Mtns. With the passing trough, will see scattered scattered showers spreading
across the high mtn valleys through the eastern mts and immediate adjacent plains through
Sunday night, with some light snow accumulations possible as snow levels drop to between
7-8K ft Sunday and down to 5 K ft Sunday night.

.LONG TERM...(Monday through Friday)
Issued at 358 PM MDT Fri Oct 21 2022

1)Lower confidence in specific weather impacts when another trough
of low pressure traverses over or near the region late next week.

Monday...Medium range guidance is a little quicker with the passing
mid-level shortwave trough of low pressure across southeastern
Colorado. Due to this quicker movement we collaborated a quicker
decrease in PoPs and precipitation Monday. This wave will also
provide much cooler air with daytime temperatures nearly 20 degrees
below late October averages. Overnight lows heading into Tuesday
morning should officially put an end to our growing season in
southern Colorado.

Tuesday -  Wednesday...Warming trend expected as the mid-level
pattern flattens out a bit ahead of the next potential digging mid-
level trough. Expecting mostly dry days with lighter winds which
should help abate any fire weather issues.

Thursday - Friday...This far out we're talking about much lower
confidence on weather impacts across the region, at least in terms
of magnitude and specifics. The potential does exist for more higher
elevation snows, stronger winds, and more elevated fire weather
conditions over the plains.

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 will continue across portions of
the southern I-25 corridor, where relative humidity values are
expected to fall into the single digits and winds are expected to
gust up to 40 mph in some areas.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday

On Saturday, critical fire-weather conditions are expected across
the I-25 corridor and the southeast Colorado Plains. Relative
humidity values are expected to fall into the low teens, and
westerly winds are expected to gust up to 40 mph.

A strong storm system is expected to bring widespread impacts across
the region starting Saturday night and continuing through at least
Sunday night. This includes very strong winds, heavy mountain snow
and blowing snow, blowing dust across lower elevations, and continued
critical fire-weather conditions over the plains. Impacts from the
strong storm system could linger into early next week, though forecast
confidence decreases considerably beyond this weekend. Nevertheless,
cooler conditions will likely overspread the region for early next
week, when we could see our first hard freeze across the plains.

.SPOTTER INFORMATION STATEMENT...

Weather spotters will not be needed today or tonight.
