Showers and storms will continue to push east ahead of a frontal band moving from the central and southern Plains into the lower Mississippi valley on Sunday. Further to the north, rains will move from the mid Mississippi valley into the Great Lakes and Ohio valley. Wintry precipitation along the northern extent of the precipitation shield is expected to produce some accumulating snows across portions of northern Wisconsin, northeast Minnesota and the U.P. of Michigan, where Winter Storm Watches and Advisories have been posted for Sunday. This system along with a lingering frontal stretched along the Southeast and Mid-Atlantic seaboard, will help to reintroduce precipitation to the eastern U.S. on Monday. Ongoing heavy precipitation across western Washington will give way to scattered, lighter precipitation as the associated frontal band advances east of the region later today. Meanwhile, precipitation will begin to develop further east, including some heavy snows across portions of the northern and central Rockies. Winter Weather Advisories and Winter Storm Warnings are in effect for portions of southwest Montana southward along the Idaho and Wyoming border, as well as further east from southeast Wyoming into central Colorado. In addition to heavy snow, strong gusty winds will generate very dangerous travel conditions for portions of the area Sunday into Monday. As the front pushes further east on Monday, precipitation is expected to redevelop across the Plains and Mississippi valley. A moist and unstable airmass emanating from the Gulf of Mexico is expected to spread north ahead of the front, supporting numerous shower and thunderstorm development from the central Gulf Coast and lower Mississippi valley northward into the Tennessee and Ohio valleys by late Monday. The Storm Prediction Center is highlighting an expansive Slight Risk area for severe storms across the area, with an embedded Enhanced Risk area centering over the lower Mississippi into the Tennessee valley. The Storm Prediction Center notes that numerous severe storms with the potential for damaging winds and tornadoes are expected Monday evening into the overnight hours across this region.
