A cold front moving through the nation's midsection brought scattered rain showers to the central plains and upper Mississippi Valley after earlier dusting parts of Nebraska, Wyoming and Colorado with light snow. Elsewhere, low temperature records were broken or tied in West Virginia and a gale warning was posted in Virginia and North Carolina. The showers were scattered primarily from northern Illinois and southern Wisconsin to eastern New Mexico, with showers also reported in southern South Dakota and western Nebraska. Light snow was reported at Sidney, Neb., and Cheyenne, Wyo., and parts of Colorado, the National Weather Service said. Ahead of the cold front, strong and gusty southerly winds prevailed across much of the Great Lakes region, and from southern Kansas to the western two-thirds of Texas. Much of the eastern United States shivered overnight, but sunny skies allowed the temperature to reach the 50s and 60s by early afternoon.
