How this weekend’s storm differs from past two

There will be another storm this weekend, but, unlike the past two weekends, rain looks like it will be a much bigger factor in Southeastern New England. The weather setup is not as favorable for snow near the coast, and some areas may see mostly or all rain depending on the storm’s track.

Basic Weather Setup

The basic setup has the big storm that is moving through the Midwest today heading into the Great Lakes and weakening by early Saturday. At the same time, a southern branch storm developing over the Southeast goes from the Mid-Atlantic to south of Long Island by Saturday night. High pressure situated to the east-northeast of the system will not do a great job of holding any cold air in near the coast, and an easterly wind will likely lead to a changeover or mainly rain. Comparing the weather maps for the past two weekend storms to this storm, it’s clear that this is not the same setup as either of the past two weeks.

Last weekend's E MA blizzard - storm developed farther out at sea, wind was north-northwest, lots of cold air behind the storm.

This weekend - weakening low over the Great Lakes draws milder air north. High pressure over Nova Scotia is moving offshore, allowing for an easterly wind to develop and not holding in the cold air over SNE as the storm tracks close to the coast.
