A large storm system moving through the Central Plains this afternoon will continue to track northeastward tonight across the Upper Midwest and into east-central Canada by Sunday afternoon. To the north and west of the low center, an ongoing significant winter storm will continue to bring the potential for heavy snowfall, gusty winds, and localized blizzard conditions from the Upper Mississippi Valley to the Upper Great Lakes and parts of the Northeast through Sunday. Widespread winter storm warnings and advisories are in effect from Minnesota to northern Michigan where up to 8 inches of snow could fall, with locally higher amounts. Into the Northeast, 2 to 6 inches of snow are forecast with some light to moderate icing possible as well. Farther south and east, widespread rain and thunderstorms along and ahead of the cold front will continue from the Ohio Valley to the Gulf Coast this evening, shifting eastward into the Southeast and Mid-Atlantic states overnight tonight. Some storms, mainly this evening, may be capable of producing severe weather and/or heavy rainfall. SPC has parts of the Tennessee Valley into the lower Ohio Valley within a slight to enhanced risk of severe weather this afternoon and evening, while WPC has highlighted the same region within a slight risk for flash flooding. Elsewhere, temperatures in the East will be warmer than average Sunday into Monday ahead of the big storm system in the Central U.S. while behind the system, a large area of surface high pressure will keep temperatures near or below average for much of the remainder of the nation. Out West, another upper level system moving down the West Coast will bring some rain to parts of California, with rain and mountain snows increasing by Monday afternoon across Southern California and the Southwest.
