Though a storm developing off the Eastern Seaboard Thanksgiving week will be very large in area, the impact on New England should be fairly small. The biggest factor in the storm forecast is its position, both as it develops and as it slowly tracks northeast across the Western Atlantic, with rain and wind focused on the north and west side of the storm circulation. This setup means that the Carolinas and Southern Mid-Atlantic (south of hardest hit Sandy areas) should see some downpours and wind through early week, but thereafter, the bulk of the precipitation shield will stay over the Atlantic. In New England, a prolonged east wind eventually may send a deck of marine, low-altitude clouds pivoting westward from the ocean, clouding the skies by Tuesday, and a few showers may even result near the far South Coast Wednesday, but barring a significant change to the forecast evolution of the storm, no greater impacts are expected, and the storm should move even farther east by Thanksgiving Thursday, allowing high pressure to firmly control the Eastern United States, complete with sunshine and somewhat moderating temperatures, with Northeast highs in the 50s.
