Frontal analysis for 21 Z Thursday 11 Dec shows that the front pasing over New England yesterday has stalled off the coast. A coastal cyclone will track along this front tomorrow, intensifying the precipitation over New England. This indicates that the precipitation pattern over New England will not change much until the cyclone has passed tomorrow evening. This will be a nasty ice storm in coastal Maine, southern New Hampshire, and Western Massachusetts. If you were planning to drive into these regions tomorrow, don't. Roads will be a sheet of ice.
