An area of low pressure will move eastward over the upper Midwest on Monday. This system will usher light to moderate showers across the upper Mississippi Valley and the Great Lakes, while light, scattered snow showers will trail this system over the northern high Plains. A cold frontal boundary associated with this system will extend south southwestward over the central and southern Plains. As this cold front shifts eastward, showers and thunderstorms will develop over the upper Midwest, the middle Mississippi Valley and the central Plains. Conditions will remain mostly clear across the southern Plains and the Intermountain West.
Meanwhile, a strong low pressure system will approach the West Coast. This system will influence an onshore flow over the Pacific Northwest, bringing another round of rain to Oregon and Washington. Early morning and late evening snow showers will be possible across the higher elevations of the Cascades. The Desert Southwest will continue to experience dry conditions due to a ridge of high pressure over the eastern Pacific.
