A coastal low pressure system will deepen today just off the coast of New England, producing substantial amounts of rain, ice, and snow across the Northeast U.S. and the Canadian Maritimes. Northern New England will see the brunt of the snowfall, especially across the higher elevations, with over a foot of accumulation possible. Many areas in the valleys and lower elevations in central/northern New England will receive significant ice accumulations, with over 1/2 inch of accumulation possible. As the low pressure area deepens this afternoon/evening and moves towards Cape Cod, winds will increase across the region, leading to power outages in the hardest hit areas from ice. A regional radar loop from this morning is shown below:


The RUC forecast for 2300 UTC this evening shows the low pressure center just west of Cape Cod, with an MSLP of 996 mb. While this doesn't seem like a very deep system based on surface pressure, it is a fairly strong system when viewed relative to the surrounding anticyclones. Stay tuned for updates on the snowfall and ice totals from this textbook coastal storm.
