More heavy rain expected in the Northeast on Wednesday

/by

A complex storm system will continue its evolution throughout the United States from later Tuesday into Wednesday. The first round shifted northeast of the Mid Atlantic this evening, moving towards Southern New England. A strong low level jet associated with this system aided in the development of widespread heavy rain, with many areas receiving well over 1″ of rainfall by the time the system ended.

Another disturbance, embedded within the same storm system, will approach the Northeast US on Wednesday. Ahead of its arrival, southwest winds will commence and warm, moist air will push northeast late Tuesday Night into Wednesday ahead of a warm front. This will allow some areas of dense fog to develop during the overnight period and into the morning hours of Wednesday.

Multiple rounds of heavy rain likely in the Northeast this week

/by

An expansive and multi-faceted storm system will develop throughout the United States during the early and middle part of the upcoming week. Multiple pieces of energy will move from the Plains through the Mississippi and Ohio Valley’s and eventually towards the Northeast — each disturbance aiding in the development of heavy rain over a relatively large area. While wintry precipitation and severe weather are both possible in the Central United States, the main focus in the Northeast will be periods of heavy rain — much needed in many areas.
