Here is today's video forecast. With each weather system changing character as it moves, it's a good idea to keep checking back for the latest info from AccuWeather.com.
With very warm air across the southern Plains and cool air farther north, the setup favors the development of showers and thunderstorms in the contested zone. As a series of cool air pockets aloft moves over this zone, a new batch of storms takes shape with each disturbance. The result is heavy rain, with the most at locations with multiple events. This map shows one-week rainfall totals from last night's ECMWF (European) mode. Note how varied the prediction is for the Middle Atlantic coast. Only a small change in the size or track of any disturbance during this period could produce a very different result.
On the south side of each new thunderstorm-producing disturbance, violent thunderstorms will erupt.
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.
