.SHORT TERM /THROUGH WEDNESDAY NIGHT/...
Issued at 346 AM MDT Tue Oct 20 2026

Today is going to be a pretty mild day but a little warmer than
yesterday. High temperatures will be in the 60`s for Albany, Carbon,
and western portions of Laramie county. Areas east of I-25 minus
majority of Laramie county will have high temperatures in the low to
mid 70`s. This difference is caused by potential brief rain showers
inherited from Colorado between 3-6pm. While the hi-res models show
some weak showers producing the environment is kind of lack luster.
The most unstable CAPE (MUCAPE) hits only about 200 joules while the
models soundings depict a decent dry layer near the surface. Mid-
level water vapor isn`t entirely supporting the idea of anything
significant occurring as it has some moisture advecting in but its
not really going to be enough to override the dry air surrounding
it. So, the most we may end up actually getting is a cloudy skies
with slightly breezier winds underneath. If moisture does end up
making it to the ground it doesn`t seem evident to expect anything
more than a brief sprinkle that barely wets the cement. Pops under
15 percent were kept for this afternoon so the chance for any precip
doesn`t show up in our weather grids. But the cloudiness will likely
drop the temperature down a few degrees compared to our clear sunny
areas, so thats why Albany, Carbon, and majority of Laramie county
are expected to be in the 60`s today. Overnight temperatures tonight
look to be in the 30`s and 40`s so something rather seasonable for
our forecast area. Wednesday will also be a pretty mild day with
light winds in the 60`s and 70`s. Light winds are forecasted once
again for the area as we will kind of be in the middle of two flows
located in the Pacific northwest and the desert southwest of the
United States. Things look to ramp up Wednesday evening as a weak
shortwave starts to inch closer to the Intermountain West to give us
increasing cloud cover at the very least. The positive about that is
that clouds act as a little bit of a blanket at night and help us
keep the warmth closer to the ground. The overnight temps for
wednesday night will be in the 40`s and 50`s for the most part.

.LONG TERM /THURSDAY THROUGH MONDAY/...
Issued at 131 PM MDT Mon Oct 19 2026


Thursday...Moist south southwest flow aloft develops in advance of
the upper low over Nevada, with deeper moisture and a weak shortwave
trough aloft moving across our western counties, producing scattered
showers and a few thunderstorms south of a line from Rawlins, to
Wheatland to Cheyenne.

Friday...As the main trough aloft moves across western Wyoming, a
cold front will lie north to south across our counties, helping to
produce scattered showers mainly west of I-25 in the afternoon, and
spreading eastward in the evening.

Saturday...The primary trough aloft moves overhead early in the day,
and orographic lift will likely produce scattered showers in the
afternoon from Douglas to Laramie, and in the evening south of a
Rawlins to Scottsbluff line.

Sunday/Monday...Drier conditions return under northwest flow aloft
and as the low and mid levels dry out somewhat. 700 mb temperatures
near 3 Celsius will yield high temperatures in the mid 50s to lower
60s.

.AVIATION /12Z TAFS THROUGH 12Z WEDNESDAY/...
Issued at 533 AM MDT Tue Oct 20 2026

VFR Conditions will remain through the TAF period. Medium to
high based clouds are expected to start pushing through this
afternoon. Looking at the cloud bases in Colorado, they range
between 10,000 and 16,000ft with some potential of cloud bases
being as low as 6,500ft but its uncertain if those lower cloud
decks will make it here. Between 21 and 01z there is some
potential for very brief rain showers for KLAR and KCYS.
However, the feeling that it may end up as virga also has a
pretty good grip in the back of my mind. Winds are expected to
lightly gust this afternoon up to 20 knots but will become
pretty light after 00z.
