Maryland Weather: Alert Day Issued For Winter Weather Through Friday Morning

BALTIMORE (WJZ) -- An Alert Day is in effect through Friday morning as a wintry mix will likely create slick roads.

The most significant icing threat is for western Maryland.

An Ice Storm Warning is in effect for Garrett and Allegany Counties through 10 a.m. Friday.
