A strengthening coastal storm will bring soaking rains to portions of the Mid-Atlantic and Northeast, with accumulating snow likely across the higher elevations of northern New England through Friday. A Pacific storm system will bring heavy low elevation rain, and gusty winds to northern California and the Pacific Northwest, as well as possible blizzard conditions to the Sierra Nevada on Friday.
