NASHVILLE (AP) — The National Weather Service has lifted all frozen precipitation watches and warnings in Tennessee as warmer air moves into the state.

There are still some slick spots for drivers to be wary of and some school systems remain closed. However the Memphis City Schools and the Shelby County Schools went back into session Wednesday after dismissing early because of icing conditions on Tuesday.

The weather issue became one of flooding. Flood warnings were posted for the northwest corner of the state and up the Tennessee River Valley in East Tennessee.

Expected high temperatures Wednesday included 40 degrees in Memphis, 38 in Jackson and Nashville, 51 in Chattanooga, 49 in Knoxville and 54 in the Tri-Cities.
