Water vapor satellite shows stormy weather in Plains (dark blue). That's leading edge of arctic air. Notice the big "u" shaped pattern in Pacific...that system heads southeast to Gulf of Mexico and turns up East Coast Sunday and Monday. Away from coast...cold air trapped with result in ice...further north...interior New England gets it's first general snowfall....coastal areas should see rain...starting as snow/sleet.
Above...you see the storm mid section...which heads northeast and allows cold air to move to the East Coast this weekend. Below...amounts of precipitation expected this weekend.
Jet stream map...look in the far upper left. The jet streak coming south will be the instigator for the storm in the East Sunday and Monday.
