Spring Break usually implies going on vacation at some place warmer than home. In this case, I mean spring itself is taking a break. Not that it needed one, of course. The very cold air mass now dwelling in the Great Lakes and Northeast will actually be reinforced as a large high pressure area from northwest Canada arrives on the scene tomorrow night and Wednesday.
With a powerful storm off the Northeast coast interacting with the big high, it will feel as cold as some of the coldest days we had in midwinter. However, the high will move off the coast Thursday and a rapid warmup will follow. This video has more. It should reach the 50s in New England and 60s farther south.
Until the actual storm takes shape tomorrow, there will be some uncertainty about snow amounts. Our thinking has been that the very worst of the storm is offshore. However, even a small amount of snow tomorrow night can cause slipping and siding on streets and sidewalks.
Some bands of rain broke out in the I-95 corridor, the most important of which brought a batch of heavy rain to the New York City area between 8:30 and 10 a.m.
in response to the approach of a deepening trough from the Plains, a Midwest low pressure area will grow stronger as it moves east to arrive on the New England coast Saturday morning.
In the I-95 corridor from D.C. to NYC, temperatures will be up past 80 this afternoon. However, between now and Saturday, a major change is on he way.
In eastern New England, an onshore flow of cool damp air prevailed all morning. There could be a last-minute warmup this afternoon. The affected areas will certainly be warmer tomrrow morning than they were this morning.
Now, out-of-season warmth is set to be the rule through midweek from the Ohio Valley to much of New England. Peak leaf color in Pennsylvania and New Jersey ranges from now northern mountains) to Halloween (in parts of South Jersey).
The Pacific storm caused some strong thunderstorms in northwest Oregon yesterday, bringing an end to a very long hiatus in the need for tornado warnings there. Note also the lack of tornadoes in eastern Tennessee.
