.SHORT TERM /THROUGH SUNDAY NIGHT/...
Issued at 117 PM MST Sat Nov 7 2026

The upper level ridge is slowly canting towards the Intermountain
West while being anchored off the West Coast. Currently high level
clouds are moving through the region as a result from the trough
moving through the northern tier of the United States. There is
another low pressure system also pushing into the Pacific Northwest
that will help center the ridge over the Intermountain west
overnight. By doing so, the upper level low over Mexico will be
cutoff from the upper level flow as our ridge creates a rex and
eventually form an omega block over the Rocky Mountain Region. WInds
will begin to pick up Sunday afternoon as the height gradient begins
to tighten as the Low in the Pacific Northwest pushes against our
area of high pressure. The Craig to Casper height gradient reaches a
max of 45-47 meters Sunday and Monday so High winds aren`t expected
but wind gusts between 35-45 mph cant be ruled out. 700mb
temperatures also max out between 6-9C Sunday afternoon warming the
afternoon temperatures into the 60`s and potentially low 70`s for
some areas. Consequently overnight temperatures will be a touch
warmer overnight as well with temperatures in the 30`s and 40`s.

.LONG TERM /MONDAY THROUGH FRIDAY/...
Issued at 117 PM MST Sat Nov 7 2026

Warm and dry weather looks to continue for the forseeable future. On
Monday, we will have a broad and fairly flat ridge positioned over
the region. A weak surface front will creep into the High Plains and
push up against the Laramie range, keeping light winds in place over
the eastern areas, while those along and west of the Laramie range
turn breezier. With 700-mb temperatures in the +4 to +7C range, we
should see continued above average temperatures and overall pleasant
conditions. A weak and moisture starved clipper system will traverse
near the area on Tuesday into Wednesday. A few sprinkles or flurries
will be possible, but only a small minority of ensemble members
support any precipitation whatsoever for the region. Expect this to
knock 700-mb temperatures down to the 0 to +2C range, while pulling
the surface trough well east of the Laramie Range. This will allow
breezy conditions to spread into the High Plains. Temperatures are
expected to remain above seasonal averages, but with the cool down
we should be a little closer to normal (perhaps 5 to 8F above
average). While most will be breezy, high winds are fairly unlikely.
In-house guidance shows probabilities around 20 to 30% for the
typical wind prone areas.

Behind the departing clipper system, ensembles are in excellent
agreement showing a highly amplified ridge building in over the
Rockies Thursday into the following weekend. This feature will block
or deflect any incoming storm systems, and push temperatures well
above average once again. Since we`ll be on the periphery of this
ridge, temperature expectations are not too extreme. 700-mb
temperatures around +4 to +6C are currently shown in the NAEFS mean,
which is near the climatological 90th percentile. This isn`t quite
warm enough to support record highs, but expect temperatures at the
surface to range a good 10 to 15F above seasonal norms. The strong
ridge will likely also keep winds fairly light during this
period.

.AVIATION /00Z TAFS THROUGH 00Z MONDAY/...
Issued at 445 PM MST Sat Nov 7 2026

Upper level ridge axis will translate eastward over the area through
Sunday with quiet weather and dry conditions. Occasionally breezy
between 17z and 23z Sunday with gusts around 20 knots for most
terminals.

HAZARDS/WEATHER TRENDS: VFR conditions will continue over the next
24 hours with intervals of high clouds early this evening, and again
Sunday afternoon.
