Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 259 PM EST Sun Dec 08 2019 Valid 00Z Mon Dec 09 2019 - 00Z Wed Dec 11 2019 ...Accumulating snow with bitter cold temperatures for the north-central U.S... ...Above average temperatures for the eastern third of the nation along with rain through Tuesday... A storm system which entered California on Saturday will exit out into the Great Plains tonight. Moderate to heavy snow will spread eastward from the northern High Plains into the Upper Mississippi Valley tonight. Storm total snowfall of 4 to 8 inches is expected by Monday evening from North Dakota into north-central Minnesota and northern Wisconsin. Locally heavy snow up to about a foot will be possible in and around far northwest Wisconsin into the western U.P. of Michigan where lake enhancement will combine with a favorable low track to the southeast of the region. Snow will end from west to east during the day on Monday. In addition to the snow up north, a strong cold front will allow modified arctic air to filter down into the northern and central Plains bringing high temperatures roughly 15 to 25 degrees below average from the Dakotas into the Upper Mississippi Valley. It will be windy in the wake of the initial cold frontal passage but winds will pick up with a secondary surge of colder air to reach the north-central U.S. Monday evening. This will generate dangerously low wind chill values of -20 to -3o degrees from the eastern Dakotas into the Upper Mississippi Valley. High temperature departures from average will range from -10 to -20 behind the cold front as far south as Texas for Tuesday. Out ahead of the cold front, temperatures will warm rather anomalously for December. High temperatures well into the 50s are forecast for the Ohio Valley and portions of New England on Monday with low 80s for portions of Texas. By Tuesday, 70s are expected for the Mid-Atlantic region with 50s and 60s for the Northeast. With the warmer weather will come rain however, with over 1 inch of rain possible for portions of the Upper Ohio Valley into New England through Tuesday evening.
