Despite abundant sunshine, high temperatures will be around 15 degrees below average with wind chills in the single digits to low teens. After a clear and bitterly cold Tuesday night with low temperatures in the single digits, southerly winds of 12-25 mph will usher more seasonable air back into northern MD and southeastern PA.
