.KEY MESSAGES...

- Above normal temperatures and dry conditions will continue for
  atleast the next seven days.

.DISCUSSION /Through Sunday/...
Issued at 1043 PM MST Sun Nov 8 2026

Warm and quiet weather will continue on Monday. Mostly sunny
conditions are expected with the exception of a few high
clouds in the mid to late afternoon for the northern plains and
higher terrain. Highs will be in the mid 60s to around 70 degrees,
which is 10 to 15 degrees above normal for this time of year.

Models are in better agreement on the positioning of the upper level
shortwave Tuesday into Wednesday. The GFS has trended more
northeast, with the other models trending more southeast, meeting in
the middle of what they`ve been showing the past couple of days.
Although there will be some lift associated with the shortwave,
moisture is too low when it moves through for precipitation
development. At the surface, a cold front will move through mid
Tuesday into early Wednesday. Winds behind the front will be breezy
from the west/northwest which will allow for decent downsloping and
warm temperatures Tuesday afternoon. This could lead to elevated
fire weather conditions across portions of the northern plains
Tuesday afternoon. Cooler (but still above-normal temperatures) will
exist for Wednesday. However, these slightly cooler temperatures
will be short- live as our next upper level ridge starts to build
behind the shortwave.

Upper level ridging will develop over the western U.S. Wednesday
and Thursday. An upper level low will approach the southwest coast
of California Friday and Saturday, pushing the ridge axis over
the area. Temperatures will remain above normal and dry Thursday
through the weekend, with our next hope for precipitation early
next week as the upper highs gets ushered out of our area.

.AVIATION /12Z TAFS through 12Z Tuesday/...
Issued at 422 AM MST Mon Nov 9 2026

VFR will persist through the TAF period with only SCT high clouds
above 20,000 ft AGL and no visibility restrictions. Fairly normal
diurnal wind patterns will persist. There was a weak surge noted
across the Northern High Plains, which means a slight enhancement
of easterlies is expected toward 19Z with sustained speeds of
9-12 kts with a few gusts to 15-17 kts possible til about 23Z.
Then winds will transition back to their normal SE-S-SW
progression 02Z-06Z-09Z, and hold SW til about 18Z Tuesday.
