Minor Snow For Sunday Night Into Monday

8:32 PM

For the past several days I have advertised the idea of a light snow developing Sunday night through Monday morning for southern portions of the forecast area, specifically for southern New Jersey.  

Moisture is now starting to develop over Nebraska and expand eastwards towards the north/central Plains.  As this moisture moves eastwards towards the Ohio Valley, a mid level disturbance will intensify.  Tomorrow afternoon, the disturbance will begin to interact with the Appellation Mountains and the moisture will begin to dry out due to a typical down sloping effect.  As the disturbance begins to interact with the Atlantic, moisture will redevelop over southeastern Pennsylvania, central and southern New Jersey, and eventually the immediate New York City metro area.  The following precipitation map will show what I think will be the impact areas.

Grey:  No precipitation is expect in these areas.

Light Blue:  Generally snow flurries are expected with possibly a dusting at most by Monday morning.

Blue:  The mid level forcing will be more organized in these areas as a band of light snow develops over this location by early Monday morning.  The snow accumulations are generally expected to range from a dusting to an inch.  An isolated two inches will be possible should a small band of moderate snow develop due to some weak Ocean enhancement at 850 MB.  This is not likely, but still possible.
