KEY MESSAGES

- Near to just above average temperatures and dry conditions are expected through this weekend.

- Breezier winds return Sunday into Monday, however fire weather conditions are not anticipated at this time.

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.
