Discussion              

An Arctic air mass has pushed into the Mid-Atlantic region and the next couple of days will feature well below-normal temperatures for the latter part of January.  The core of the coldest air will be in place late tonight and late night temperatures lows will likely drop to the lower teens in much of the region.  Low pressure will form near the southeastern US coastline on Friday and enter a rapid intensification phase as it moves to the northeast at week’s end.  Snow is likely to break out here later Friday and continue into Saturday from what is looking increasingly likely to be an unfolding intense ocean storm with wide-ranging impacts. It is still a bit too early to determine the ultimate storm track and exactly when the explosive intensification will take place, but all residents in the Mid-Atlantic/Northeast US should continue to closely monitor this unfolding situation.
