Boise, Idaho – Rain taps steadily on windshields this morning, turning roads slick and slowing traffic across the Treasure Valley as conditions continue to deteriorate through midday.
According to the National Weather Service, widespread showers will persist through the afternoon with near 100% precipitation coverage and rainfall totals reaching up to a half inch in some areas . Winds remain light but steady, and visibility may briefly drop during heavier bursts.
In Boise, Meridian, and along I-84, drivers should expect wet pavement and longer braking distances through the late afternoon commute. Ponding water could develop on low-lying roads. Keep headlights on and allow extra travel time. If you’re heading toward Eagle or Nampa, conditions remain similar with consistent rain coverage.
Showers begin to taper later today, but cooler air settles in quickly. Temperatures fall into the mid-30s by Thursday night, raising the risk for isolated slick spots on bridges if surfaces refreeze. This is the time of year when brief “flash freezing” can catch drivers off guard.
Looking ahead, conditions improve Friday with sunshine returning and highs near 58°F. The weekend trends milder and brighter, offering a break from the damp pattern. However, the broader weather pattern remains active across the West, with mountain snow continuing in higher elevations nearby.

Today: High 54°F, steady rain, wet roads
Thursday: High 57°F, slight shower chance, clearing late
