Forecast Montana is the definitive portal for the Treasure State’s weather and climate — built to make the official National Weather Service forecast fast, clean and highway-clear for all 56 counties, from the Idaho line and the Bitterroot over the Continental Divide to the Front, the Hi-Line and the plains at the Dakota line.
Montana is two states in one weather map. West of the Divide the Pacific gets in: Missoula and the Flathead run milder and wetter, the valleys hold their inversions for weeks, and August belongs to the fire season. East of it there is nothing between the Hi-Line and the Arctic, and Havre and Glasgow post some of the coldest readings in the lower 48 — Rogers Pass holds the record at 70 below. In between, the Rocky Mountain Front makes chinooks that moved the thermometer 47 degrees in seven minutes at Loma, still a world record. Four NWS offices — Missoula, Great Falls, Billings and Glasgow — cover it. Forecast Montana is built to tell that whole story, county by county, region by region.
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. Montana takes a sandstone paper and a Butte copper accent — the ore under the Richest Hill on Earth that made this the Treasure State — its own note in the network.
Montana is covered close-up by 9 region sites, each on its own subdomain of forecastmontana.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 Montana, not separate sites: /about on any of them lands back here.
Montana has live neighbors on every side: Forecast Idaho over Lookout and Monida, Forecast Dakotas down I-94 at Wibaux and up the Missouri at Fairview, Forecast Wyoming across the Beartooth and the Powder River country, and Forecast Canada along the 49th parallel for Alberta, Saskatchewan and British Columbia — all tinted in their own accent on the hero map and clickable from it. Montana grew up as part of Forecast Great Plains, and the rest of the network — Forecast Washington, Oregon, Idaho, Michigan, Illinois, Indiana, Ohio, Oklahoma, Texas, Maine, Colorado, California, Florida, Georgia, Alabama, Wisconsin, Minnesota, Carolinas, Alaska, Dakotas, Arizona, Missouri, Tennessee, New Jersey, New York, Pennsylvania, Maryland, Delaware, New Mexico, Nevada, Kentucky, Louisiana, Utah, Arkansas, Mississippi, Hawaii, Iowa, Kansas, Nebraska, Wyoming, Virginia, New England, Great Plains, Canada — is the same system, one exit apart.
