Boise, Idaho – Increasing rain chances and warmer temperatures are expected midweek, potentially affecting travel and outdoor plans.
According to the US National Weather Service Boise, precipitation probabilities rise across southwest Idaho beginning Tuesday, with some areas seeing the highest chances during the day. McCall shows the greatest likelihood, peaking near 65% Tuesday, while Boise and surrounding Treasure Valley communities generally range between 5% and 30% through the period.
The graphic indicates rain chances gradually expand Tuesday into Wednesday before tapering off later in the week. Most locations—including Caldwell, Meridian, Nampa, and Mountain Home—show consistent but lower-end probabilities, suggesting scattered showers rather than widespread continuous rainfall.
At the same time, temperatures trend significantly warmer. Boise is expected to climb from the low 60s Sunday into the mid-70s by Tuesday, with similar warming across the region. Meridian and Nampa follow a comparable pattern, reaching the low-to-mid 70s Tuesday before slightly cooling midweek. Mountain areas such as McCall remain cooler, with highs in the low 50s.
By Wednesday and Thursday, temperatures dip modestly but remain mild, generally ranging from the upper 50s to upper 60s across the Treasure Valley.
The combination of warmer air and periodic showers could create variable conditions for commuters, especially during peak travel hours Tuesday.
For students and young workers, the shifting weather may affect midweek schedules, particularly for those relying on walking or transit.
Residents are encouraged to monitor updates from the National Weather Service Boise for any changes in timing or precipitation coverage.
