An occluded boundary extended southward from the low across Nebraska, before connecting to the triple point near Kansas City, KS. A stationary boundary stretched eastward from the triple point through Missouri and the Tennessee Valley, while a cold front extended southward through Oklahoma and Texas. Meanwhile, a frigid arctic airmass continued to surge south over the central Plains and Intermountain West, with a southward advancing cold front analyzed to the southwest of the main low, ushering in temperatures 10-20 degrees below average behind the front. Current surface observations and RADAR depicted a broad swath of moderate to heavy snow along on axis north of the low, extending from the upper Midwest westward through the northern and central High Plains and Intermountain West, while a transition zone consisting of mixed precipitation and freezing rain was located in western Minnesota and Wisconsin. Moderate to heavy rainfall was also falling along a north-south axis extending from the Midwest southward through the Mississippi Valley. ...Selected preliminary Storm Total Snowfall in inches from 700 AM PST Tue Dec 11 through 600 PM PST Mon Dec 14... ...COLORADO...

GOLD BEACH 3.00 SELMA 2.33 Snow is expected to gradually dissipate across the Intermountain West overnight, while moderate to heavy snowfall and blizzard conditions continue across portions of the central and northern High Plains. A rather broad swath of 12"+ of snow is forecast to fall along an axis extending from South Dakota northward through North Dakota, eastern Montana, and the upper Midwest with localized areas potentially receiving over 2 feet of snow, especially across the western Dakotas and northeastern Minnesota. Freezing rain is also expected to continue in the upper Midwest through Wednesday with up to 0.25" of ice expected to accrue across the region through tomorrow, especially in portions of Minnesota and Wisconsin. On a longer-term scale, impacts are forecast to spread eastward as a 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 are currently forecast along an axis extending from northern Virginia and Maryland northward across western Pennsylvania toward Lake Erie. 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. 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 $$
