KEY MESSAGES

- After a brief relative cooldown through Tuesday, the dry and warming trend returns through the end of the week.

- Inversions may break provided there is sufficient mixing but stagnant conditions will return for the latter half of the week as upper level high pressure ridge moves overhead by Wednesday.

SHORT TERM /THROUGH WEDNESDAY NIGHT/

Issued at 115 AM MST Tue Feb 3 2026

Early morning satellite imagery shows mid/high clouds streaking across the region in association with a weak impulse embedded within the upper flow aloft east of the area. Over the next couple of days, a weak ridge will build across eastern Idaho supporting generally quiet weather and seasonably warm temperatures. Skies will be mostly sunny to party cloud the next few days although there is a potential, albeit low, for some localized valley inversions to develop overnight, particularly in the Snake Plain, with some localized fog or low stratus possible. Confidence in this is low however. All in all, things look to remain quiet throughout the area as we move into the middle part of the week. Temperatures the next few days are expected to continue to climb into the upper 40s to lower 50s across much of the lower elevations throughout the Snake Plain and Magic Valley. This is about 10 to 15 degrees above normal for this time of year.

LONG TERM /THURSDAY THROUGH MONDAY/

Issued at 1235 PM MST Mon Feb 2 2026

Upper level ridge rebuilds overhead Wednesday and will see very mild and dry conditions through Saturday. Highs if no inversions form will be in the 40s mountains and 50s to near 60 valleys through Saturday. Lows teens and 20s mountains and 20s and 30s valleys. Long range models are indicating the ridge breaking down next week with a bit of a pattern chance. European model the quickest and have some chances of precipitation back in grist late Sunday and widespread precipitation on Monday. Highs by Monday in the 30s mountains and 40s valleys. The light winds will continue through the period with some increase.

AVIATION /12Z TAFS THROUGH 12Z WEDNESDAY/

Issued at 344 AM MST Tue Feb 3 2026

VFR conditions are expected at all eastern Idaho terminals through the next 24 hours. Light winds and partial clearing overnight could allow for some localized BR or low clouds around KDIJ or KIDA but the probability of this is 20 percent or less. Winds will remain around 10 kts or less through the period with no precip expected.
