A retrograding cutoff low will continue to meander northwest-ward around Nova Scotia today. At the same time, another storm system will remain well to New England’s south as it slides away from the east coast. Between these systems is a wedge of very dry, almost desert-like, air. This air mass over much of New England will preclude showers from the cutoff low for much of New England today.
As the cutoff low continues to drift around the Canadian Maritimes, it will send scattered showers into eastern Maine. The very dry air mass will be eating away at these showers, which will keep precipitation on the light side. Trends over the last 24 hours have been toward a sharper westward cutoff in shower activity as it looks like the very dry air mass will win out and eat away at the showers as they move past eastern Maine. Spotty freezing rain showers remain possible across easternmost Maine this morning before switching to rain showers.
