Weather Underground Forecast for Monday, January 23, 2012.

The strong storm system of the Plains will continue to provide active weather to the East on Monday as the system lifts northeastward from the Central Plains to Wisconsin by the morning and Lake Superior by Monday evening. Moderate to heavy snowfall will fall in the northern edge of this system from the Mid-Mississippi Valley through the Upper Great Lakes. Meanwhile, abundant moisture ahead of this system will trigger a mix of rain, freezing rain, and snow in the Upper Peninsula of Michigan. Significant ice and snow accumulations will be possible by Monday evening. To the south, widely scattered showers with periods of heavy rainfall and thunderstorms will develop ahead of an associated frontal boundary moving through the Eastern Valleys and Gulf Coast States. Light to moderate showers will also be possible in the Mid-Atlantic, to the north of an associated warm front.

In the West, a powerful storm system carrying a significant plume of moisture will provide more rain showers and heavy high elevation snowfall to northern and central California. Isolated thunderstorms will also be possible across much of central California with locally heavy rain, gusty winds and small hail. Precipitation from this system will spread into the Central Great Basin, southern California, and the Southwest. Meanwhile, precipitation is expected to continue in the Northern Intermountain West. Temperatures in the Lower 48 states Sunday have ranged from a morning low of -28 degrees at Clayton Lake, Maine to a high of 84 degrees at Robstown, Texas
