Special Weather Statement

Special Weather Statement issued March 16 at 1:03PM EDT by NWS Morristown TN
Mar 16, 1:03 PM Mar 17, 12:00 AM
As additional precipitation spreads across the area this
afternoon and evening, periods of a rain may mix with or
transition to primarily snow at times. Some locations may see a
dusting of snow primarily on grassy or elevated surfaces. Minimal
travel impacts are expected outside of reduced visibilities under
the heaviest precipitation. For tonight into Tuesday morning,
there is potential for residual moisture on area roadways to
freeze into black ice and result in slick spots. Take caution on
your morning commutes.
