DISCUSSION

Issued at 213 AM MDT Sun May 3 2026

Little changes in the forecast as a whole. Outside chance for showers today, mainly over the central mountains as the ridge over our area breaks down and a low pressure system approaching the California coast begins to interact with a bigger trough positioned to our northeast. Better chances for scattered showers and thunderstorms exists Monday into Tuesday as the low moves through the southwestern U.S. We're not expecting much precipitation from this system, although some local areas could pick up a quick 0.25" inches from a thunderstorm. Winds begin to pick up from the northeast on Tuesday with that system to our south. Looks like winds will be strong enough for a lake wind advisory on the American Falls Reservoir with strong chop likely near the dam. Colder air works into the region on those northerly winds, and it looks like we could be in store for another round of frost/freeze for Wednesday morning. Temps look more reasonable than what we dealt with reasonably, lower 30s across the Snake Plain. The ridge builds back in for Wednesday and beyond with dry weather likely for the latter half of the week. There's an outside chance for some rain next weekend as a weak system passes to our north. Temperatures rebound with some areas flirting with 80 degrees by the end of next week.
