Special Weather Statement

Special Weather Statement issued February 5 at 1:06PM EST by NWS Morristown TN

Feb 5, 1:06 PM → Feb 6, 2:00 AM

Cold temperatures tonight will continue to cause slick travel
conditions through at least Friday morning. Icy spots on roads
will likely persist in many locations due to residual moisture on
roads that will freeze as temperature fall into the 20s. Be
prepared for slick spots, especially on untreated secondary
roadways and overpasses. Use caution if traveling tonight and
Friday morning.
