More dangerous cold and wind chills are forecast Wednesday in the Baltimore area, with a chance of flurries in the afternoon, according to the National Weather Service.
Temperatures are expected to climb only to the upper 20s from overnight lows in the teens. At BWI Marshall Airport, the mercury dropped to 12 degrees early Wednesday, the coldest temperature recorded there in almost two years exactly -- it fell to a low of 8 degrees Jan. 24, 2011.
Skies should be sunny but winds still gusty, with 15-20 mph breezes making it feel as much as 15 degrees colder.
