This NOAA satellite image taken Sunday, Jan. 15, 2012 at 12:45 a.m. EST shows mostly clear skies domiate the East Coast as a trough of low pressure slowly moves away from the Northeast. This allows for snow showers to diminish over the Great Lakes, as drier air moves in from the north. Meanwhile, another trough moves into the Northern Plains, bringing light rain and snow showers with it. (AP PHOTO/WEATHER UNDERGROUND)

Snow showers continue to taper off over the Northeast and Great Lakes, but more wintry weather is expected to spread across the West on Sunday. A low pressure system arising from the Gulf of Alaska will continue advancing into the Pacific Northwest.
Several cold fronts associated with this system will continue moving from the Pacific Northwest and the northern Rockies into the Great Basin late Sunday night. Snowfall totaling 2 to 5 inches is expected across Idaho and Montana, while the Cascades may see another 3 to 6 inches of new snow.
Only 1 to 2 inches of snow are expected across northern Utah. Expect temperatures to remain 10 to 15 degrees below seasonable across the U.S. Northwest. The tail end of one cold front will sweep through far northern California and the northern Sierras and may trigger some rain showers and high-elevation flurries.
At the same time, the cold front will produce strong winds around the region. Due to prevailing dry conditions across California, these strong winds will increase the fire danger. Expect wind gusts to range from 30 to 40 mph, up to 50 mph gusts are likely across higher elevations.
In the East, snow showers will diminish across the Great Lakes, Ohio River Valley, and Northeast as a strong low pressure system continues moving farther away and into eastern Canada. Elsewhere, a high pressure will continue to build in from the Plains and Mississippi River Valley, allowing for drier and calmer conditions.
Cool temperatures and breezy conditions will persist through the extreme Northeast through Sunday evening. Temperatures in the lower 48 states ranged Saturday from a morning low of -14 degrees at Pellston, Mich., to a high of 80 degrees at Alexandria Esle, La.
