A nor'easter may develop by the middle of the week and it could be a long duration event for some.
An upper-level area of low pressure will slide southeast from the Great Lakes and develop a surface low off the Mid-Atlantic coast Tuesday night. This low will then remain off the New England coast through at least Thursday. The low will also deepen as it meanders off the Eastern Seaboard.
This low will combine with a strong surface high pressure system in eastern Canada to create a tight pressure gradient which will bring strong winds into the Northeast.
The subtropical jet stream will also move north which will bring tropical moisture northward, enhancing the rainfall across the region.
Anywhere from the northern Mid-Atlantic to New England will likely be affected by heavy rain and strong winds. The exact track of the low will determine the timing and location of the heaviest rain and strongest winds.
The strongest winds and heaviest rain will most likely occur on Wednesday and Thursday, with over five inches of rain possible in some areas of Maine.
