Forecast Idaho is the definitive portal for the Gem State's weather and climate — built to make the official National Weather Service forecast fast, clean, and highway-clear for all 44 counties, from the Nevada line and the Owyhee desert up the Snake River Plain, over the Sawtooths and the Frank Church, and north through the Palouse and the Clearwater to Bonners Ferry and the Canadian border.
Idaho is 480 miles tall and cut in two by the clock, and both facts are weather. The line is the Salmon River: north of it the Panhandle takes Pacific storms and Spokane's time, and Coeur d'Alene has more in common with Seattle than with Pocatello. South of it the Snake River Plain is a high desert that traps a winter inversion for a week at a time while the Sawtooths above it collect the snow — Stanley drops below freezing more nights than anywhere else in the lower 48, and Borah Peak stands 12,662 feet over a valley that sees twelve inches of rain a year. Forecast Idaho is built around that north-south split rather than the flat map of it.
The look borrows from the American Interstate system — the reflective paper, the green guide signs, the blue service signs, the brown recreation signs, and the red-white-and-blue route shields — set in Overpass, the typeface drawn from the Highway Gothic lettering on those signs. Idaho takes a Palouse loess paper and a star-garnet purple accent — the state gem, dug from the St. Joe River drainage in the Panhandle and found in commercial quantity in only one other place on earth — its own note in the network.
Idaho is covered close-up by 1 region site, on its own subdomain of forecastidaho.com — the same maps, the same live radar and the same climate record as this site, drawn to one metro or region instead of the whole state, with a page for every city in it. They are part of Forecast Idaho, not separate sites: /about on any of them lands back here.
Idaho has six live neighbors, more than any site in the network: Forecast Washington across the Palouse, Forecast Oregon down the Snake at Fruitland, Forecast Nevada at Jackpot and Owyhee, Forecast Utah at Malad Summit on I-15 and the Snowville grade on I-84, Forecast Montana over Lookout and Monida, and Forecast Canada for British Columbia at Eastport — all tinted in their own accent on the hero map and clickable from it. The rest of the Forecast <State> network is part of the same system Forecast Wyoming is live over Teton Pass and the Palisades, and tinted here too.
