A soaking rain storm is unlikely to unfold in the eastern U.S. this week, impacting the Mid Atlantic and Northeast with two waves of significant rainfall. With cold air absent from the region, this will be an all-rain event with snow confined to central and northern Maine.

A wet weather pattern is in store for large areas of the lower 48 to the east of the Mississippi River over the next few days. This will be along and to the east of a slow moving frontal boundary stretching southwest to northeast from the Southern Plains into the Mid Mississippi Valley, Ohio Valley and into the Northeast and ahead of two areas of low pressure moving from the central Gulf coast up along the east coast. According to the National Weather Service, moisture values are expected to be much above average along and to the east of this front and ahead of the two areas of low pressure moving along the east coast, supporting the potential for widespread regions of precipitation.

The heaviest rainfall totals expected from the central Gulf coast, across portions of the Southeast and Mid-Atlantic where the two areas of low pressure are expected to move across. The lead area of low pressure will spread rains across the Mid-Atlantic Monday night and into the Northeast on Tuesday. This will be followed by another low moving from the central Gulf coast Tuesday night, into the Southeast Wednesday and the Mid-Atlantic Wednesday night.

The heaviest rain is expected Wednesday night into early Thursday, with portions of New Jersey, Delaware, and eastern Pennsylvania and New York seeing the heaviest totals.
