.SHORT TERM /THROUGH TUESDAY NIGHT/...
Issued at 1234 AM MDT Mon Aug 3 2026

Changes are in store through the short term period, albeit short-
lived, from what we`ve been experiencing as of late. The big feature
of note will be a cold front that dives south across the CWA by
Monday evening, increasing the threat of a few showers and possibly
a thunderstorm over the Laramie Range. However, as depicted by hi-
res guidance, the coverage appears to be limited due to the dry
conditions locked in at the lower levels. This is shown by the
`Inverted V` soundings that are in place, so if minimal moisture
advects in, most of the showers will become VIRGA and produce only
gusty winds. The other thing of note in the environment that we are
in, due to dry lower levels, any thunderstorm development may
produce dry lightning which could make the fire weather concerns
more critical. Therefore, Red Flag Warnings continue along and
east of the I-25 corridor as min RH values will tank once again
below 20 percent. However, these lower RH values may be short-
lived as the cold front, and associated increase in moisture,
dives south across the CWA by Monday afternoon/evening. Winds
will play a huge part if we see the critical conditions ahead of
any additional moisture that would be associated with the cold
front passage. So, as everyone knows that our winds tend to over
perform, the Red Flag Warning that was issued for said area
will remain out into Monday evening. The Red Flag Warning for
our western zones remains more of a likely scenario to verify as
the environment will be more critical, those warnings remain
out through Monday evening.

So, now we are post frontal and a cooler air mass is in place, so
Tuesday will be a much cooler day then what we`ve been having
as highs will only top out in the 70s to near 80 for many
locations across the CWA. Winds will not be much of an issue
outside of the higher terrain as the surface gradient tightens
up ever so across the Laramie Range where gusts 30-35 mph are
possible. Enjoy this cooler day as it will be a one off, more on
that in the long term.

.LONG TERM /WEDNESDAY THROUGH SUNDAY/...
Issued at 1234 AM MDT Mon Aug 3 2026

Will keep this long term discussion short a sweet as there is not
much to talk about with the synoptic set-up that will take hold over
the region. Starting off the long term period, Wednesday marks the
day that the warm-up begins as ridging builds back in. This will not
only usher in warmer temps but block or hamper any moisture
transport into the region. Therefore, expect dry conditions with
highs topping out around 80 degrees F. As the ridge builds, so will
the heat as highs Thursday will climb back to near 90. Then the real
heat makes a return Friday into next weekend as highs once again
surge into the upper 90s and low 100s, warmest across far eastern
Wyoming and the Nebraska Panhandle. As mentioned briefly, with the
ridge strengthening, don`t expect much relief from any precipitation
as we will remain dry heading into next weekend.

.AVIATION /12Z TAFS THROUGH 12Z TUESDAY/...
Issued at 525 AM MDT Mon Aug 3 2026

VFR conditions will prevail across all terminals through this TAF
period. Expect generally light and variable winds at the start of
this forecast, with an increase increase by this afternoon into the
early evening hours with northerly winds gusting 20-35 knots. Winds
will shift to the north due to a cold front, with this frontal
passage precipitation chances still remain minimal due to ample dry
air at the lower levels. Therefore, kept any mention of
precipitation out of this set of TAFs.
