Weather Underground Forecast for Wednesday, November 30, 2011.
The storm system over the lower Great Lakes will lift northeast Wednesday and the associated cold front is expected to sweep through norther England.

Moving to the West, the Pacific system off the British Columbia will push southeast into northwestern U.S. Wednesday morning and rapidly dissipates.

Together, they will continue to support snow and low elevation rain over the Pacific Northwest and northern Intermountain West. Snow coverage will expand eastward into the Upper Midwest and southward across the Four Corners by Thursday. Apart from the precipitation, this cold front will also cause a significant wind event across much of the West Wednesday through Thursday.
