DISCUSSION

Issued at 1102 AM MST Sun Nov 15 2026

DRIER CONDITIONS FOR SUNDAY & MONDAY:

There is potential for fog and low stratus once again tonight. The only difference is that clouds moving in form the west could prohibit some of that development.

NEXT SYSTEM TUESDAY-WEDNESDAY:

Our focus then shifts to another shortwave trough moving through the area from Tuesday afternoon through Wednesday. While this system will be slightly cooler, the bulk of the precipitation is still expected to fall ahead of the cold front. As a result, snowfall totals should look similar to the previous system, peaking at 4-8" in the southern mountains, with lighter amounts farther north. Snow levels will also be hovering around 7-9 kft. Behind the front, temperatures will drop to near or slightly below normal for much of the week.

LATE WEEK SYSTEM:

Forecast models continue to show another system arriving late this week on Friday and Saturday. Models still show an open wave setup, so as a result the precipitation amounts continue to decrease. There is still some differences among the models with regards to strength and timing, so confidence is not high attm. Most of the moisture is expected to arrive ahead of the cold front, making timing critical. Snow levels could drop to some valley floors Friday night into Saturday morning. For now, however, the specifics remain uncertain.

AVIATION /18Z TAFS THROUGH 18Z MONDAY/

Issued at 1021 AM MST Sun Nov 15 2026

Dense stratus is still leaving cigs near or below ILS breakpoints at EGE, RIL, MTJ, GUC, and HDN. Look for cloud cover to clear out and cigs to lift over the next 2 to 3 hours though. This should leave conditions at VFR through most of this afternoon. The forecast is uncertain on if low-level clouds will redevelop overnight though, and if so, how dense they will be. As of now, we've inserted scattered low-level cloud cover into most TAF's and acknowledge the possibility that clouds could become broken or overcast should conditions allow. This means most terminals will be at a low risk of seeing cigs below ILS breakpoints after midnight tonight.
