Discussion

A significant cold air outbreak is headed to the Mid-Atlantic/NE US from the northern part of Canada at the end of the work week and another is coming for the early part of next week. As high pressure ridging intensifies across Alaska and western Canada, the upper-level air flow will develop in such a manner that will allow for the transport of air from way up in Canada to the central and eastern US. As the cold air pushes to the southeast late this week, moisture will push northeast along the advancing frontal boundary zone and rain is likely here late tomorrow into tomorrow night. The rain could change to snow showers late tomorrow night in the I-95 corridor and there will be accumulating snow from western New York State to the upper part of Maine with this influx of cold air. Next week's cold blast could bring a threat of snow to the Mid-Atlantic region and northeastern US.
