It's been a long time since we had a major storm cycle around here and I confess that I am really excited for the weather we will see this holiday weekend.
The Thanksgiving trough passage is really just an appetizer. The mashed potatoes and gravy, stuffing, and 25-pound butterball follow on Friday when a strong upper-level trough approaches the Pacific Northwest coast and moisture and precipitation spread inland into Utah.
It's been a long time since we've seen a time-height section like the one below. DEEP moisture for an extended period of time. There is the Thanksgiving storm, then a bit of a break, followed by strong, moist, westerly crest-level flow for about an extended period before a frontal passage early Saturday morning.
Through Saturday afternoon (5 PM) the SREF ensemble mean for Alta Collins is around 3 inches, although the range is quite large (.9 to 4.8 inches).
Details concerning snow levels, the timing of precipitation, and the intensity of precipitation are not possible to predict with precision at such long lead times. If you are traveling over the holiday weekend, monitor forecasts at https://www.weather.gov/slc/ as this is a blog post, not a forecast, and I can't do anything but hit the highlights.
If you are wondering, right now, the weather looks dry statewide on Sunday.
