KNOXVILLE, Tenn. (WVLT/AP) -- A cold front ran into very warm air over Tennessee, triggering tornado watches early Monday afternoon.
All of East Tennessee was under a tornado watch until 2 p.m. this afternoon.
By noon, the watches concerning violent weather had been canceled for all of West Tennessee, except for counties along the Alabama border, which remained under a tornado watch.
In Middle Tennessee, a tornado watch was in effect for the southern Cumberland Plateau, while heavy rain had caused the National Weather Service to issue a flash flood warning for the rest of the region, including the northern plateau.
Some school systems were delaying the start of classes because of the stormy weather.
Forecasters with the National Weather Service say there is a moderate risk of severe storms in the state.
Temperatures before dawn were in the 70s, but were expected to fall into the lower 30s by late Monday night and early Tuesday.
