Boise residents will enjoy a bright, warm start to the weekend, but the first days of October could turn wet. Temperatures climb into the mid-80s Saturday before rain chances return late Sunday night. Those heading to football games, outdoor markets, or travel on I-84 should plan now for shifting conditions.
According to the National Weather Service in Boise, Saturday stays sunny with highs around 82 degrees. By Sunday, clouds increase, and a 20 percent chance of showers develops after midnight. Conditions grow wetter early next week, with up to a 50 percent chance of showers and thunderstorms by Monday and Tuesday.
The rain may affect drivers on I-84, especially during Monday morning commutes when wet roads and reduced visibility are possible. Residents should secure outdoor furniture and plan alternate indoor activities for early October. While no severe cold snaps are in the forecast yet, this unsettled pattern marks the season’s transition toward winter.
For now, fall warmth holds through Saturday with calm winds and clear skies. Sunday offers one last mostly sunny day before the shift arrives. Residents should charge devices, pack rain gear, and allow extra travel time by Monday morning.
More updates are expected if showers strengthen, with rain chances continuing through Tuesday night.
