Forecast Tennessee is the definitive portal for the Volunteer State's weather and climate — built to make the official National Weather Service forecast fast, clean, and highway-clear for all 95 counties, from the Chickasaw Bluffs and the Delta to the Cumberland Plateau and the crest of the Great Smokies.
Tennessee is 440 miles of weather laid end to end, and I-40 crosses all of it. Eight states touch it — only Missouri ties that — and each of the three grand divisions forecasts like a different place. West Tennessee is Delta flatland that floods from the Mississippi and takes the spring line first. Middle Tennessee is basin and Highland Rim, where Dixie Alley's tornadoes arrive after dark. East Tennessee is ridge and valley climbing to 6,643 feet at Clingmans Dome, where more than 80 inches of rain a year falls on the wettest ground in the eastern United States. Forecast Tennessee is built around that traverse.
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. Tennessee takes a limestone-bluff paper and a Tennessee iris accent, on Smoky Mountain haze — the state flower's violet against the color the mountains are named for.
Tennessee is covered close-up by 7 region sites, each on its own subdomain of forecasttennessee.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 Tennessee, not separate sites: /about on any of them lands back here.
Tennessee touches eight states, more than almost anywhere, and with Mississippi's site up all eight are live: Forecast Missouri across the Mississippi at the northwest corner, Forecast Arkansas across the river the length of the western line, Forecast Mississippi along the southwestern line, Forecast Kentucky the length of the northern line, Forecast Alabama and Forecast Georgia along the southern line, Forecast Carolinas over the crest of the Smokies, and Forecast Virginia at the northeastern tip — each tinted in its own accent on the hero map and clickable from it. Forecast Nashville covers Middle Tennessee's metro in its own right. The rest of the Forecast <State> network is part of the same system.
