 As a result, an expansive area of precipitation is forecast from the Ohio Valley to New England. Snowfall will continue over parts of the Ohio Valley, central Appalachians and Michigan, tapering off Wednesday morning. Snow accumulations are expected between 1 to 4 inches, with locally higher amounts possible. Meanwhile, light to moderate rain and showers will continue from eastern Great Lakes through New England. Heavier rains are likely just along and ahead of the cold front. Much of the precipitation should diminish by Wednesday evening, except a few snow showers over northern Appalachians.
Moving to the West, the Pacific system off the British Columbia will push southeast into northwestern U.S. Wednesday morning and rapidly dissipate. At the same time, a strong cold front will push through
the northern Intermountain West. 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
Wednesday through Thursday across much of the West.
Temperatures in the Lower 48 states Tuesday have ranged from a morning low of 1 degrees at Crane Lake, Minn., to a high of 86 degrees at Harlingen, Texas.
