Dry and windy post-frontal conditions are expected on much of the Plains into the Lower Missouri, Mid-Mississippi, and western Ohio Valleys as north-northwest sustained winds of 15-25 mph gusting 20-40 mph develop amid minimum relative humidity of 12-30%. Elevated to locally critical conditions are most likely from eastern Nebraska and western Iowa through eastern Kansas and much of Missouri. Temperatures will be well below normal across much of Plains, Midwest, Great Lakes, and the Missouri, Ohio, and Mississippi Valleys, especially later in the day and overnight as cold air pushes south from Canada. Above normal temperatures and minimum relative humidity of 8-25% will continue across much of the Inland Northwest, Great Basin, eastern California, and into the northern Rockies. Thunderstorms and showers are likely to continue across portions of New Mexico, west and south Texas, and the Great Lakes, including snow in portions of the northern Great Lakes. Thunderstorms are likely on portions of the Gulf and East Coasts, with showers spreading into the Northeast.
