Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 303 AM EST Sun Dec 02 2018 Valid 12Z Sun Dec 02 2018 - 12Z Tue Dec 04 2018 ...Winter storm across the Plains and Midwest will wind down today... ...Severe weather and potentially heavy rain are possible in the Southeast to Carolinas today... A surface low pressure system will continue to track northeastward over the next couple of days, moving across the Great Lakes region and into Ontario and Quebec. Snow is forecast to continue on the north and west sides of the low, but snow is expected to wind down across the Plains as the low pulls away. A cold front is forecast to form across the Great Lakes region to Ohio and Middle Mississippi Valleys, which will lead to continued chances for light snow there through Sunday night. Farther east, snow of 1 to 4 inches is expected especially downwind of the Great Lakes, as well as in northern New England closer to the low track. Freezing rain is also likely in northern New England, with a tenth of an inch of ice possible in some areas. Farther south, rain and thunderstorms are forecast ahead of the cold front associated with this low pressure system. The Storm Prediction Center has a Slight Risk of severe weather in place for parts of the Southeast into the Carolinas on Sunday--please see their website for more details on the severe threat. There is Marginal Risk of flash flooding outlooked in the same general area on Sunday, where storms could move slowly and train over the same locations. Most of the region will dry out on Monday after the frontal passage, though rain and thunderstorms will continue across Florida through Monday night as the front lingers. A low pressure system will move across the Southwest and Southern Rockies on Sunday, leading to snow the Southwest and Intermountain West, with higher totals in higher elevations of the Wasatch and San Juan Mountains. Northern Arizona could receive 6 to 10 inches of snow in mountain peaks, with 4 to 8 inches in the Wasatch. Widespread Winter Weather Advisories are in effect there, before snow chances wind down Monday morning. Another low approaching the West Coast will help create more chances of rain and snow in California and the Intermountain West by Monday night. Temperature-wise, the eastern U.S. will be mild for the beginning of the week, with high temperatures 10 to 20 degrees above average expected in the Tennessee and Ohio Valleys eastward on Sunday, and along the Eastern Seaboard on Monday (while the Tennessee and Ohio Valleys become closer to normal on Monday due to a cold frontal passage). Record warm temperatures are expected, particularly for high minimum temperatures on Monday morning. Colder than average temperatures are forecast for the western and central parts of the U.S. Tate Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
