Arctic Blast Headed for DC Tuesday Night along with the chance for Snow Showers

An arctic front will pass through the Washington Area Tuesday night ushering in scattered snow showers as well as the coldest air of the season.

Our first real chance of widespread snow flurries with embedded snow showers will come on Tuesday night as arctic air plunges into the region. Some locations could pick up a light dusting.

This mornings 12z GFS Operational run continued to show quite the snow storm over the MLK weekend. The latest 18z GFS operational run has a track more suppressed to the south. The Ensembles all have a storm system along the Gulf but there is little agreement as to whether it slides off the coast (no storm for us) or heads up the coast (NAO being negative could favor the snowy scenario). Again as I said yesterday, a Nor’easter is possible… no guarantees, will need to be watched.

    Am hoping that the powerful upper trough going through on Tuesday can give us a quick inch or two, like the Valentines Day event from last winter.

    My opinion is that we will get some type of snow event over MLK weekend. Whether minor or major is the question.
