Some stormy weather is on the way, and it may not be just rain for at least a part of the region.
High pressure builds in for tonight and the first part of Friday with clear skies, diminishing winds, and chilly conditions. Clouds start to move back in late Friday ahead of a pair of systems. The first, a weak upper-level disturbance moving out of the Great Lakes will bring in some light precipitation before daybreak Saturday. With chilly weather in place, it may start as snow north and west of Boston, with rain to the south. The snow should change to rain before midday, but some minor accumulations are possible, mainly from the hills of Worcester county into the Monadnocks, but also across parts of Southern New Hampshire, where an inch or two is possible. The second system, a stronger low pressure area will move up the East Coast, bringing in some steadier and likely heavier rain late Saturday into Saturday night. Many of the models are showing the potential for 1-3 inches of rain, which could result in some areas of flooding. The storm pulls away early Sunday, but we need to keep an eye on a second area of low pressure that will develop off the Carolina coast on Sunday. It will likely stay too far offshore to have any appreciable impact on the region, but as it meanders around offshore, it could send in some clouds and possibly a few showers to Cape Cod and southeastern Massachusetts later Sunday into Monday. Otherwise, high pressure builds in with dry and cool conditions.
