Freezing temperatures could creep into the region and cause slippery conditions early Thursday in some areas.
Weather observers reported high temperatures on Wednesday of 68.9 degrees around 1:30 p.m. Wednesday in Hagerstown, Md., and 62.2 degrees around 1 p.m. The record high temperature for both towns was 70 degrees set in 1947.
Pennsylvania Department of Transporation spokeswoman Pamela Kane urges motorists to use extreme caution, decrease their speed and increase their following distance when traveling in adverse weather conditions. PennDOT will have crews monitoring and treating roads throughout the evening and into Thursday morning.
