Boise drivers could face slick roads Tuesday night as showers and thunderstorms push across western Idaho, with wet conditions lasting through midweek. Anyone traveling on I-84 or commuting in and around Boise should plan for slower travel and potential delays as rainfall increases Tuesday evening.
According to the National Weather Service in Boise, a 20% chance of showers begins Tuesday afternoon with storm chances increasing after sunset. Thunderstorms may develop late, bringing brief heavy rain, gusty winds, and reduced visibility. Showers continue Wednesday with a 50% chance of rain during the day and lingering moisture into the evening.
Daytime highs cool noticeably this week. Boise hits 81 degrees Tuesday before dropping to 74 Wednesday and mid-70s Thursday. The cooler trend signals a seasonal shift toward fall. By Friday, temperatures dip into the upper 70s with sunny breaks returning by the weekend.
Residents are urged to use caution on roadways when rain begins. Hydroplaning risk increases during the first minutes of rainfall when oils rise on the pavement. Travelers should allow extra time for commutes and keep headlights on in reduced visibility. Those planning outdoor activities should monitor conditions and have a backup plan indoors.
Showers taper into Saturday with clearer skies by Sunday. While this system does not bring major flooding threats, unsettled conditions could persist through late week. More updates are expected as the storm develops.
