Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 213 PM EST Mon Dec 30 2019 Valid 00Z Tue Dec 31 2019 - 00Z Thu Jan 02 2020 ...Storm winds down over the Northeast... ...Lake effect snow down wind from the Great Lakes... ...Rain and mountain snows return to the Northwest... The winter storm across the north-central U.S. will begin to wind down while producing heavy snow to portions of the Upper Midwest and Great Lakes through Monday. Additional snow accumulations of 6 to 12 inches, with locally higher amounts, are possible. Gusty winds will create blowing and drifting snow and dangerous travel conditions. The heavy snow and rain/freezing rain winds down across portions of the Northeast and New England through Tuesday as moisture from this system surges northward and a surface low intensifies off the coast. As much as a quarter of an inch of ice is possible in some of the higher terrain of Eastern New York, Vermont, and Western Massachusetts where ice storm and winter storm warnings are currently in effect. Heavy snow is also expected across portions of Upstate New York to Northern New England with accumulations of 6 to 8+ inches possible. Elsewhere, a storm moving towards the Pacific Northwest will bring widespread rain and mountain snows to much of the Northwest beginning on Tuesday and lasting into the New Year. Heavy snow, in excess of a foot, is possible in the highest terrain of the Washington Cascades, and the Northern Rockies. In terms of temperatures across the nation, well above normal conditions across the Ohio Valley and Mid-Atlantic will moderate back towards average (though maybe still slightly above) by Tuesday following the passage of the cold front. In the West, temperatures are expected to be 10 to 15 degrees below normal from the Desert Southwest to the Central Rockies. The west coast will trend near average through the short range ahead of the approaching cold front. Ziegenfelder Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
