KEY MESSAGES

- Early-April Warmth: Temperatures will remain consistently 10 to 15 degrees above seasonal normals through Monday, with many valley locations reaching the mid to upper 60s.

- Breezy Tuesday Transition: A potent storm system passing to our north will tighten the pressure gradient, bringing gusty winds that may approach Wind Advisory criteria Tuesday afternoon.

- Minimal Precipitation: Aside from a few stray showers along the Continental Divide on Tuesday, dry conditions will prevail through the work week.

- Extended Mild Pattern: A split-flow atmospheric pattern develops late week, keeping Eastern Idaho in a warm and stable regime heading into next weekend

DISCUSSION

Issued at 111 PM MDT Sun Apr 5 2026

Benign weather remains in place to end the weekend across eastern Idaho as high pressure stays in control of the local pattern. Satellite imagery currently shows only a few mid-to- high level clouds passing through from time to time, allowing for ample sunshine to pair with our seasonably warm temperatures. Daytime highs today and again on Monday are expected to reach the mid to upper 60s, and it is likely that a few of our typically warmer spots will top 70 degrees before the afternoon ends. These values are quite pleasant for early April, running approximately 10 to 15 degrees above our climate normals. No precipitation is expected through the next 48 hours.

The pattern begins to shift slightly on Tuesday as a potent upper-level trough moves from Western Canada into the Canadian Prairies. While the heart of this system stays to our north, it will cause a tightening pressure gradient across the region, leading to a breezy Tuesday afternoon. We don't expect much in the way of widespread precipitation to contend with, though we could see some isolated shower chances in the eastern highlands and along the Continental Divide. For the most part, this system is not expected to be overly impactful aside from the increased wind, which could flirt with Wind Advisory criteria during the afternoon hours.

As that trough shifts well to the east, weak ridging will again build as a more widespread split upper-level flow develops across the western United States. This configuration looks to keep our area characterized by seasonably warm temperatures and generally dry weather as we approach the following weekend. Daily temperatures will continue to run roughly 5 to 10 degrees above average for both daytime highs and overnight lows throughout much of the forecast period.
