Heads UP! Squall line between 6 and 7pm for east coast, earlier DC, later New England

The National Weather Service is timing the vicious squall line to come through the NYC metro area between 6 and 7 pm, with driving rains and strong, gusty winds.

The squall is losing some of its energy since it is moving far ahead of the major upper air systems that gave birth to it and kept the squall line so intense in the southern states.

There will be more rain and strong winds overnight, with the approach and passing of the cold front.
Strong winds will continue on Thursday, and the temperatures will mostly fall all day into Friday morning. Winds will taper off during Friday.

For the extended outlook through the middle of next week, numerous waves in the upper air will produce small to moderate storm systems.
It’s hard to tell, given the jumble of upper air impulses which one might be an old-fashioned winter storm, so watch the weather forecasts.
