KEY MESSAGES

- Persistent Cold & Frost Risks: Cold overnight temperatures continue for the next couple of mornings, with a Freeze Warning in effect for the Snake Plain and Arco Desert through Thursday morning. While urban centers like Pocatello and Idaho Falls may stay near or above freezing, rural areas will likely see a light freeze with temperatures between 28F and 32F.

- Scattered Showers Today: Mainly across the southeast highlands.

- Weekend Warm-up: A warming trend begins this weekend as high pressure builds, returning temperatures to roughly 10 degrees above normal by the weekend and into early next week.

- Unsettled Next Week: Conditions become more unsettled late this weekend into next week as an upper-level low approaches the Great Basin, though the bulk of moisture may remain south of the region.

DISCUSSION

Issued at 153 AM MDT Thu Apr 30 2026

Trough of low pressure begins to shift east today. We will see some scattered showers mainly across the southeast highlands, but could see some build-up around the Sun Valley area as well this afternoon. As that trough shifts east, our overnight lows will finally begin to warm up. We most likely have one more night of freeze warnings for Friday morning across the Snake River Plain. There could be some cold spots into Saturday morning, but not probably not enough to warrant another freeze warning.

Expecting dry weather for Friday into Saturday as a ridge of high pressure slides over the area. We continue to monitor a low pressure system that will try to undercut the ridge for next week. This low may inspire some scattered showers as soon as Sunday afternoon. But the best chances are during the first half of the work week as the low moves inland. How much precipitation we see will depend upon the track of that low. Some model runs have favored a more southern track which would result in lower precipitation totals while other model runs (like the 00z GFS) favor a more northern track through Utah which would support more precipitation for central and east Idaho. One thing is certain, is this system is not nearly as cold as our previous system and we should remain mild through much of next week.
