DISCUSSION

Issued at 243 AM MST Sat Nov 14 2026

Early morning satellite imagery shows widespread cloud cover across eastern Idaho as an upper-level trough swings through the area. Regional radar depicts light-to-moderate precipitation across parts of the Magic Valley and into the Central Mountains, while areas farther east have observed only occasional light sprinkles. High-resolution convective-allowing models (CAMs) indicate this precipitation shield shifting eastward toward daybreak, with light precipitation overspreading the remainder of the forecast area over the course of the day. Overall precipitation amounts will remain generally light due to limited atmospheric moisture. Expect 0.20 to 0.40 inches of liquid equivalent across the Wood River Valley and adjacent mountains, and up to 0.30 inches from around Pomerelle eastward through the Bear River Range, though some model spread remains regarding the exact areal coverage of those higher totals. Locations outside of these favored terrain zones are expected to receive around 0.10 inches or less. Snowfall will remain generally above 7,000 feet, keeping impactful accumulations confined above pass level at 1 to 3 inches, with localized upslope totals up to 5 inches across parts of the Sawtooths, Boulders, and Pioneers. Cold advection and persistent cloud cover will make daytime highs markedly colder today, generally staying in the 40s areawide.

Eastern Idaho will reside between departing and incoming upper- level troughs on Sunday. Dry conditions will return under partly cloudy skies, allowing afternoon temperatures to rebound by around 5 degrees compared to Saturday's readings. The next Pacific storm system shifts slowly inland on Monday. The first half of the day looks dry for most locations, with precipitation gradually overspreading the region as the afternoon progresses under temperatures similar to Sunday. This system will drive a notably colder air mass into eastern Idaho behind it, setting up Tuesday as a day where snowfall could reach much of the region, including down to valley floors. Exact snow levels remain difficult to pinpoint at this range; higher elevations will certainly see light accumulations, and light accumulations cannot be completely ruled out in the valleys. At this stage, however, lower elevations appear hard-pressed to see substantial accumulation, though trends will be monitored closely in upcoming forecast cycles. The mid-to-late portion of next week looks to remain unsettled with continued broad troughing over the Pacific Northwest and periodic waves of embedded moisture pushing through the Intermountain West. Daytime valley highs will likely remain restricted to the upper 30s and lower 40s from Tuesday straight into next weekend, accompanied by continued daily chances for light snow.

AVIATION /12Z TAFS THROUGH 12Z SUNDAY/

Issued at 428 AM MST Sat Nov 14 2026

Widespread cloud cover in place across the region this morning with rainfall gradually shifting into the Snake Plain and will continue to push eastward throughout the morning. Low end VFR to MVFR in place currently with MVFR/IFR CIGs likely with rainfall. Winds will be breezy, 15-20 kts, in the valley terminals today. Precip will taper off later this afternoon and skies will slowly clear overnight with some mid/high level clouds expected to move in as we push into Sunday AM.
