DISCUSSION

Issued at 139 PM MST Wed Feb 11 2026

Afternoon satellite imagery shows widespread cloud cover in place across the area as moisture as rain and snow continue to fall across the region. After some early morning snow in the lower Snake Plain, we've changed over to rain while a rain/snow mix is still lingering across portions of the upper Snake with all snow across the higher terrain. Hi-res CAMs show most of the precip tapering off shortly after sunset with just some scattered rain/snow showers (elevation dependent) continuing into the morning and afternoon hours on Thursday. Winter Weather Advisory remains in place this afternoon and into the day tomorrow although it may be canceled early as additional snowfall accumulations in the eastern highlands after this evening will be pretty hit-or-miss in nature and should amount to much based on the latest forecast. Temperatures continue to run above mid-Februrary norms throughout the region the next few days although cloud cover will make it feel a bit more on the chilly side with not too much sunshine for most.

Late week and into the weekend, weak ridging builds overhead supporting mainly dry conditions outside of some orographically enhanced showers across the central mountains and eastern highlands but the lower elevations are expected to remain dry. Despite expected mid/high level cloud cover, lower elevation temps in the mid 40s to lower 50s appear likely with the area residing on the northern edge of a ridge of high pressure.

This ridge will begin to give way to broad upper troughing across the western U.S. as we move into the start of the upcoming work week. The pressure gradient looks to tighten across our area allowing for winds to increase Mon-Wed next week and the SW flow aloft looks to support bringing in moisture off the Pacific into eastern Idaho. At the onset Monday, snow levels look to be too high favoring rain in the lower elevations and snow in the mountains. As we move into Tuesday and Wednesday, snow levels look to gradually lower as cooler air moves in but just how much remains to be seen as models have differing opinions on the depth of the colder air. NBM blend is hedging its bets and lies as a compromise solution between the model discrepancy which shows snow levels hovering right around valley floors at the end of the extended forecast period. Confidence this far out in time is still low however so expect things to change over the days ahead.
