Discussion
An Arctic cold front will arrive here tonight and the winds will pick noticeably as colder air begins to pour into the Mid-Atlantic region. This frontal passage will usher in the coldest air mass of the season so far for the end of the work week and beginning of the weekend and temperatures could bottom out near the 20 degree mark by early Saturday morning. Overall conditions will be less harsh on Sunday and Monday, but it’ll remain colder-than-normal for this time of year and there could be some rain to start the new work week from low pressure near the Mid-Atlantic coastline. More cold air outbreaks are destined to follow later this month into the central and eastern US as a “high-latitude blocking” pattern develops way up north.
