DISCUSSION

Issued at 1030 AM MST Sat Nov 14 2026

CURRENT STORM:

A shortwave trough is currently tracking over the area. It has resulted in widespread rain and snow showers. Snow levels made it down to about 7 kft this morning and those may slightly rise through out the day, especially if there is a break in the precipitation. The southern mountains are still favored to receive an additional 1-4" of snow with lesser amounts for the central and northern mountains. Rain amounts have reached 0.50" in spots with another 0.25" possible. Showers will start to dissipate this evening with most places dry by midnight. Tomorrow and Monday look to be mostly dry with slightly warmer temperatures.

NEXT STORM:

Another shortwave trough very similar to the current is expected to impact the area on Tuesday and Wednesday. We should expect similar precipitation amounts and snow levels (7-9 kft). This system is slightly cooler, but the bulk of the precipitation is ahead and along the front. When the cold front arrives on Wednesday most of the showers will be decreasing in coverage. Snowfall amounts are much like the current system with the highest totals in southern mountains around 4-8" and lesser amounts further north.

LATE WEEK STORM:

The models continue to advertise another storm Friday and Saturday although the trends are shifting towards an open wave, much like the previous two systems. Due to the model inconsistency confidence is not high at this point, but with an open wave the precipitation amounts have trended downward. Timing will be something to watch with this wave as it may bring the snow levels down to some of the valleys Friday night into Saturday morning. Although once again the bulk of the precipitation is forecasted to occur ahead of the coldest air, so it does not appear the valleys will get much attm.

AVIATION /18Z TAFS THROUGH 18Z SUNDAY/

Issued at 1010 AM MST Sat Nov 14 2026

Most terminals continue to be at risk of seeing precipitation over the next 4 to 8 hours. HDN, VEL, and CNY have a lower chance of this, but a few light showers through the late morning and afternoon cannot be ruled out. As showers pass over, vis may periodically fall to MVFR or IFR. Cigs will likely sit below ILS breakpoints through the afternoon and potentially evening as well for all terminals aside from VEL and CNY, regardless of if showers are passing through or not. Look for some improvement in cigs after 12Z, though confidence is low on how much clouds will clear out or cigs will lift at this point in time.
