Accumulating snows will continue into the evening and overnight hours on Saturday for portions of the Mid-Atlantic and Northeast as an area of low pressure continues to strengthen and track north along the coast. Additional heavy accumulations are possible across portions of Long Island, southern and central New England, as well as coastal and eastern Maine before the system tracks into the Canadian maritime Provinces on Sunday. Lake effect snows are expected to continue in Sunday, with locally heavy amounts possible along the northern shores of the U.P. of Michigan. Lake effect snow warnings are in effect on Sunday for areas east of lakes Erie and Ontario as strong westerly winds will help support narrow bands of heavy lake effect snows, producing areas of low visibility and heavy snow cover. Then Sunday night into Monday, more widespread but generally light snow is expected to spread from the upper Midwest into the Great Lakes region as a clipper system drops out of Canada. Dry conditions, with above normal temperatures are expected to continue across much of the western U.S., as well as the central and southern Great Plains. Critical fire conditions will persist across southern California. Strong Santa Ana winds, along with very low relative humidity, will create critical fire weather conditions for portions of the region on Sunday.
