Every forecast across The Treasure Valley,
highway-clear.

Every Idaho region shares one system — the same maps, the same live radar, the same climate record. Nearly half of Idaho lives in one valley that gets twelve inches of rain a year — a high desert with a mountain range on its northeast shoulder. The Boise Front turns a January inversion into a week of gray on the valley floor while the foothills sit in sun a thousand feet above it, and every August the cheatgrass on the Owyhee side carries fire faster than anything in the timber.
