A deep plume of moisture from the subtropical Pacific Ocean was being drawn northeastward along a frontal boundary stretched from the Louisiana Gulf Coast north and east to the Carolina coastline. Several ripples of low pressure were riding along the boundary, and should be in the vicinity of Cape Hatteras later this morning. The entire system is then forecast to move northeastward and out to sea during the day today.
After a slick morning commute, conditions should start to slowly improve through the day as the region lies in between the departing the storm and another approaching disturbance from the upper Great Lakes. This disturbance will send a cold front through the region Thursday morning. Chances for snow shower activity will increase during the late night hours tonight and into Thursday morning with the passage of the system. High pressure will build in behind it, along with some chilly air to close out the work week.
A series of systems looks to cross the region over the weekend. Chances for some light snow showers cannot be completely removed for the weekend thanks to this parade of systems. A more powerful cold front, associated with more of an Arctic airmass, looks to push through the region during the afternoon and evening hours on Martin Luther King, Jr. Day. A round of snow showers, increasing winds, and winter's chill look to be in the air thereafter, as a bitterly cold airmass looks to take aim at the region in the wake of the Arctic front.
