Snow falls early Sunday, March 17, 2013, as an Amish family travels to church services near Maysville, Ky.
A pair of storm systems that were moving across the country on Sunday could join forces to bring snow to the Northeast — even as the official start of spring approaches next week.
One storm was spreading snow showers from the Cascades and northern Rockies into the northern Plains and was expected to bring snow to the Dakotas, Minnesota and western Wisconsin tonight, the Weather Channel said.
There was also a chance of snow in West Virgina, southwest Pennsylvania and northwestern Virginia Sunday night, according to meteorologists.
Another storm system was moving over the Ohio Valley Sunday and was expected to continue moving east, joining the northern system to produce a "fairly potent storm off the New England coast Tuesday," the Weather Channel said.
In addition, severe thunderstorms were in Monday's forecast from southern Ohio down into Kentucky, Tennessee and parts of Alabama, Mississippi, Louisiana and northeast Texas.
Snow was expected to close in on parts of the Northeast as the work week gets underway. The Weather Channel said the best chance for accumulating snow and freezing rain was in New England and other interior sections of the Northeast.
Snow is also possible on the I-95 corridor from Washington to Philadelphia Sunday night and from New York to Boston Monday night.
The National Oceanic and Atmosphere Administration called for a chance of rain in New York City Monday, with showers also forecast for Tuesday. NOAA also forecasted snow early Tuesday morning in Boston, but little accumulation is expected as the precipitation turns to sleet and rain during the day.
Wednesday marks the first official day of spring.
