GOLD BEACH 3.00 SELMA 2.33 Snow is expected to continue gradually dissipating across the Intermountain West through today, while moderate to heavy snowfall and blizzard conditions continue across portions of the central and northern High Plains. An additional few inches of snow is forecast to fall along an axis extending from Minnesota through the Dakotas and into Nebraska as the snow starts to clear out through tonight. Snow will intensify in the upper Midwest as a secondary low forms over Great Lakes region and enhances lift. Additional accumulations of up to 1 foot is expected in this area, with locally higher amounts possible. Freezing rain is also expected to continue in the upper Midwest through Wednesday with up to 0.1" possible across north-central Wisconsin and Michigan. Tonight into tomorrow, impacts are forecast to spread eastward as another secondary low pressure develops in the Southeast and tracks northeastward along the East Coast, bringing winter impacts to interior portions of the Mid-Atlantic and Northeast. Potentially significant freezing rain accretions of 0.1"+ are currently forecast along an axis extending from northern Virginia and 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" possible tomorrow and into this 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 PM PST. Please refer to your local National Weather Service office for additional information on this event. Genz $$
