Mount Holly's thoughts on early next week...
By Sunday, high pressure builds offshore of New England, then the front to our south will begin returning northward as an area of low pressure moves out of the Great Lakes and toward the Mid Atlantic. However, the models diverge in how they handle the low. Models differ in how fast they bring the low into the area and how fast the low exits. The GFS brings it in and exits it faster, while the the ECMWF is slower. As the low pressure and associated frontal boundaries affect the area, an extended period of rainfall can be expected. So there will be a chance of rain from at least Sunday, through Monday night, but the chance of rain could last into through Tuesday night.
