BOISE, Idaho – Morning commuters across southern Idaho can expect breezy, unsettled weather as fall tightens its grip heading into Sunday, October 12. Gusts up to 28 mph could make for challenging travel on I-84 through Boise and Meridian, especially for high-profile vehicles.
According to the National Weather Service in Boise, a 30% chance of showers will linger Friday and Saturday before skies begin to clear Sunday afternoon. Temperatures will swing from highs in the low 80s today to the mid-60s by early next week — a notable dip signaling the region’s first real fall cooldown.
Drivers should secure outdoor decorations and delay leaf burning as winds increase through the weekend. While no frost or freeze alerts are currently posted for the Treasure Valley, residents are urged to keep an eye on early morning lows that could slip into the low 40s by Monday.
Outdoor plans Saturday may face brief interruptions from scattered showers, especially across Ada and Canyon counties. However, by Columbus Day, partly sunny skies and calmer winds should return — ideal for pumpkin patch visits or early Halloween decorating.
Long-range models hint at a second cool push by midweek, bringing another round of light showers and overnight lows in the 40s.
