Friday 10 a.m.
A chilly northwesterly flow of basically dry weather will affect the I95 corridor this weekend. As a high pressure area settles over New York and New England on Monday and Tuesday, it will still be chilly, but probably less windy with more sunshine. The ECMWF model is leading the way on predicting a northeaster at midweek with snow in the mountains and rain in the big cities. See it here:
The European model has a northeaster on the East Coast Wednesday night. The GFS model has the storm offshore. This map shows the European version.
A personal note: meteorologists are always interested in big storms. However, I never want to root for one or cheer it on. The immense human toll of suffering and disruption of the most basic need to live in safety with enough food and water.. in New York City and surrounding areas... reinforces this.
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.
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).
