.SHORT TERM /THROUGH SUNDAY NIGHT/...
Issued at 229 AM MDT Sat Oct 3 2026

A pleasant weekend is expected with sunny skies and mild
temperatures. A bubble of high pressure continues to sit over the
Four Corners region, leading to the benign weather. Subsidence under
the ridge will ensure limited cloud cover with no chance of
precipitation on both Saturday and Sunday. A shortwave passing to
the northeast of the forecast area on Saturday will lead to breezy
north winds throughout the day. Northerly winds will cause a subtle
drop in high temperatures compared to Friday. Highs will be about 5
degrees cooler, but will remain about 10 degrees above average for
early October. Winds will ease Saturday night, with clear and calm
conditions. This will allow for effective radiational cooling,
leading to more seasonable overnight lows. Sunday will be a few
degrees warmer compared to Saturday. Winds will shift out of the
south and west, ushering warmer air in to the forecast area. High
temperatures on Sunday will be in the 70s and 80s, making for a
picturesque fall day for outdoor activities.

.LONG TERM /MONDAY THROUGH FRIDAY/...
Issued at 1249 PM MDT Fri Oct 2 2026

Dry and significantly warmer than average conditions expected
for the entirety of the long term period. The work week will
start with very warm conditions as a ridge of high pressure
controls the Western US, with highs in the widespread upper 70`s
west of the Laramie Range, and mid to upper 80`s to nearing 90
to the east. Probabilistic guidance is in unanimous agreement on
this heat, with only a 3 degree spread noted in highs for the
Cheyenne area specifically. These highs will also be almost 20
degrees above normal for this time of year, and record
temperatures will be on the line for several locations across
the forecast area on both sides of the mountains. Finally, this
will be the driest day of the week with RH values bottoming out
in the mid to low teens. This alongside breezy daytime winds
could return us to critical fire weather conditions, and will
need to be monitored over the weekend for any necessary
products.

The ridge will flatten out and shift a bit more southward
through the rest of the week which will help slightly alleviate
these temperatures, but expect highs remaining in the 70`s and
80`s through Friday. A slight increase in moisture could also be
possible, but slight is the keyword here, and we will still see
elevated fire weather danger thanks to RH values still dropping
into the upper teens to low 20% range. Our only indication of
any hint of moisture occurs on Tuesday during this slight
pattern shift, with a single time period of a slight shower
chance at the top of the mountains, so dry it`s impressive.
Unfortunately models are also in unanimous agreement on this
pattern, and the only variances noted in ensemble clusters is
how far east or west the ridge over our area shifts by the end
of the forecast period. While this could slightly increase or
decrease our highs by the end of the week, the message remains
the same no matter what - hot and dry through the first full
week of October.
