Area Forecast Discussion
National Weather Service Pueblo CO
Issued by National Weather Service Denver CO
931 AM MDT Mon Oct 17 2022

.UPDATE...
Issued at 930 AM MDT Mon Oct 17 2022

Temperatures have warmed sufficiently and well above freezing,
allowing all freeze and frost products to expire on time this
morning. The forecast is right on track with mostly sunny
conditions and slight moderation in temperatures today. An
isolated light shower or two will be possible in the San Jaun's
but nothing significant to disrupt a pleasant autumn day. Highs
will reach the 60s across the plains, upper 50s to lower 60s in
most of the high mountain valleys, and 30s and 40s over the
mountains.

It will be cool again tonight with a dry airmass, mostly clear
skies and light winds. We'll address potential for another
frost/freeze highlight in the afternoon package.

&&

.SHORT TERM...(Today and tonight)
Issued at 356 AM MDT Mon Oct 17 2022

...Frost and freeze conditions are expected this morning across
much of the plains north of highway 50 and east of the northern
I-25 corridor, and then again tomorrow morning over most of the
plains...

Key messages:

1) Areas of frost and freeze conditions will impact much of the
plains during the early morning hours. This will be the case for
tomorrow morning, for much of the plains as well.

2) A few showers and high elevation snow showers will be possible
over the southern mountains this afternoon.

Detailed discussion:

Today...

Areas of frost and freeze conditions will impact much of the plains
early this morning, mainly north of highway 50, within the lower
Arkansas River Valley, and along the northern I-25 corridor and
eastward. Due to this, there are freeze warnings for Kiowa, Crowley,
Prowers, and El Paso Counties and a Frost Advisory for Pueblo County
until 9 AM.

An upper level low that is currently over central New Mexico will
continue to fill and progress eastward throughout the day. This
should remain far enough to the south that there will not be any
showers over the CWA, however there could be a few isolated showers
or even high elevation snow showers over the highest peaks, of the
most southern mountains by later in the day. Instability with the
latest CAMs does not appear to be favorable for showers to become
convective enough to support any thunderstorm development. There
will be a slight rebound in temperatures from where they were
yesterday, although still slightly below the average as the
persistent east to southeasterly flow continues over southeast
Colorado behind the major shortwave trough well upstream over the
eastern CONUS. Higher pressure building in will allow for mostly
clear skies and dry conditions to set in. Highs will top out in the
60s over the plains, to the upper 50s and low 60s for the upper
Arkansas River Valley and San Luis Valley, and generally in the 30s
and 40s for high country, and a few upper 20s for the fourteeners.

Tonight...

High pressure will be in domination of the conditions, with light
winds and clear skies expected across the CWA. Due to temperatures
dropping off quickly with radiational cooling, there will once again
be areas of widespread frost and freeze conditions across many areas
of the plains after midnight and into the early morning hours
tomorrow. Temperatures will fall into the upper 20s to mid 30s over
most of the plains, with only a few lower 40s along the front range
and over the adjacent plains, and into the 20s and low 30s for high
country. -Stewey

.LONG TERM...(Tuesday through Sunday)
Issued at 356 AM MDT Mon Oct 17 2022

Key Messages:

1) Frost and Freeze conditions will remain possible through mid
week.

2) Spotty near critical fire weather conditions possible through
the work week and into the start of the weekend.

3) Increased precipitation chances this weekend with potential
pattern change.

The region will remain situated between a large upper high to the
west and deep upper low over the eastern CONUS at the start of
the period. Colder air mass does begin to shift east of the area
on Tuesday, with the warming trend noted on this day expected to
persist for the remainder of the work week. Temps well into the
30s look to remain possible over the plains through mid week, and
will continue to message the possibility for frost/freeze
conditions during this time. Precip chances during this time and
through the work week will remain close to zero, as lacking
support and dry air are in place.

With the warming trend and dry air in place this week, will see
the potential for spotty near critical fire weather conditions,
especially across the plains. While low RH values below 15 percent
are likely, the winds don't appear to be overly strong.
Increasing flow and winds are possible this weekend ahead of an
upper trough. While this does increase fire weather concerns,
cooler temps look to help keep RH values higher. Confidence is low
with exact trends though, and will continue to keep an eye on
trends. Precip chances do increase across southern Colorado with
the arrival of this system Saturday into Sunday. At this time,
precip and snow chances look to be the highest across the
Continental Divide. While some potential for precip across the
plains and even colder temps into early next week, confidence
remains low given lack of model consistency at this time.

.AVIATION...(For the 18Z TAFS through 18Z Tuesday afternoon)
Issued at 930 AM MDT Mon Oct 17 2022

VFR conditions will prevail for all TAF sites (KALS, KCOS, and
KPUB) throughout the forecast period. Winds will be mainly out of
the east to southeast between 5 to 10 kts at all terminals this
afternoon and then become more diurnally influenced by later in
the evening and during the morning hours. Overall, a fairly normal
and light diurnal wind pattern will prevail through Tuesday.
