A secondary low-pressure system was analyzed in Tennessee with a central pressure of 1000mb (29.53 in Hg).

Additional accumulations of up to 1 foot is expected across the region, with locally higher amounts possible, especially along the northeastern shores of Minnesota, where onshore flow and orographic lift may lead to snow totals exceeding 2 feet. Light freezing rain accretions will also be possible across north-central Wisconsin and Michigan during the overnight hours with up to 0.1" possible. On Friday, impacts are forecast to spread eastward as a secondary low pressure tracks across the Southeast and moves northeastward along the East Coast, bringing winter impacts to interior portions of the Mid-Atlantic and Northeast. Potentially significant freezing rain accretions of 0.5"+ are currently forecast along an axis extending from northern Virginia and far western Maryland northward across west-central Pennsylvania. Further north, temperature profiles will be cold enough to support accumulating snow across the interior Northeast and New England, with snowfall accumulations up to 12-24" possible through the weekend. As a result of multiple days of snow, blowing snow, and freezing rain across a broad swath of the country, travel may become dangerous or impossible at times, so be sure to refer to WPC or your local NWS office to access the latest forecasts and learn about potential impacts to your area. The next Storm Summary will be issued by the Weather Prediction Center at 700 AM PST. Please refer to your local National Weather Service office for additional information on this event. Russell $$
