A low pressure area moving quickly northeastward from the Gulf states will be east of New York City by midday tomorrow and out past Nova Scotia on Thursday. It is likely to bring rainy, drizzle and at times foggy weather to the I95 corridor from DC to New York City, with wet snow more likely as it gets to Boston. In a 50 mile wide zone from northwest to southeast, it may be possible to find results ranging from 4 or 5 inches of snow at one end to more than half an inch of rain at the other. And, even where temperatures are below freezing at the ground, there may be enough warm air aloft to create a sleet or freezing rain situation instead of snow. Here is a projection for snow that was made early this morning:
This video show the rest of the forecast through early next week. I also decided to throw in a wild looking map for January 27th. The only thing I am sure about here is that this outlook will change as we get closer to that date!
A large high pressure area centered over Hudson Bay but extending south all the way to the Gulf states is creating northwesterly flow of chilly air for all of the Northeast.
On the map, one band of rain is along the coast at the north edge of the picture, the second is entering the Sierra range straight east of San Francisco, and the third extends from Los Angeles northeast to Las Vegas and on from there.
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.
