BOISE, Idaho – A calm, golden sunrise lights up the Treasure Valley this Veterans Day, but change is quietly building to the west. After a string of mild, dry afternoons, clouds will thicken midweek, setting up for a round of November rain that could dampen late-week travel and outdoor plans across southwest Idaho.
According to the National Weather Service in Boise, today stays bright with highs near 63 degrees and only light winds. Clouds increase late tonight, and by Wednesday, the valley turns mostly cloudy as moisture builds off the Pacific. Rain chances climb sharply Thursday, with the heaviest showers expected Thursday evening into early Friday. Forecasters say new rainfall amounts could total between a tenth and a quarter inch, enough to make roads slick and slow the Thursday evening commute along I-84 and Highway 55.
Temperatures will hold near 65 degrees Thursday before a cool-down begins Friday, dropping highs into the low 50s by the weekend. Models hint at another weak system Sunday or Monday, though details remain uncertain. No snow is expected at valley level, but higher passes in the Boise and West Central Mountains could see a light rain-snow mix late Friday night.
Residents should secure leaves and yard debris before the rain, and travelers are advised to check conditions for any early-morning slick spots. After all, it’s November in Idaho — and this may be the last truly mild stretch before winter’s chill settles in for good.
