Two Snow Chances

A cold front will shove the unseasonably warm 60F temps off the coast early Friday and a couple of fast moving weather disturbances might have enough cold air to produce a few flakes around here.  The chances aren’t great (20% – 40%), and these aren’t big storms, but at least snow lovers have something to watch.  The first system is associated with a jet streak passing south of Maryland Friday night (see above).  This jet streak should produce a wave of low pressure that will move northeast along the cold front as it settles down into North Carolina Friday night.  This one might be too weak, too far south, and too warm to produce a serious snow threat around here, but there is a slim chance that some moisture will make it far enough north to produce some light rain or snow in areas south of Baltimore between 6pm and 11pm Friday.

The second chance is slightly more promising.  A strong jet streak diving southeast from western Canada is expected to push a fast moving clipper-type weather disturbance through the area early Sunday (see above).  This one will have colder air to work with and it looks a little more energized.  However, clippers are usually very dry and so it might only be able to generate a few flurries or snow showers.

Snow amounts with either of these slight snow chances would be light, but our in-house RPM model does suggest a trace to an inch of snow is possible for parts of northern Maryland by noon on Sunday, and 2-4″ is possible in far western Maryland.
