Every forecast across The Scenic City,
highway-clear.

Every Tennessee region shares one system — the same maps, the same live radar, the same climate record. Chattanooga sits in a bend of the Tennessee where the river cuts through Walden Ridge, and the terrain does the forecasting: the gorge channels wind, the ridges hold fog in the valley for days, and the Cumberland escarpment above Monteagle ices over while the city stays wet. April 27, 2011 put a violent tornado through the same corridor twice in one afternoon.
