A narrow band of snow (We call these Deformation zones) will set up over northern Colorado Friday night and move from east to west Saturday. These are hard to predict with any deviation of track. This Saturday, the most likely chase spots will range from north of I-70 in Colorado and areas from Sundance in Utah to the I-80 Corridor. This wave will drag over southern California later this weekend.

A storm will work its way into the Rockies from the north this weekend and will stall out over the Southwest through early next week with snow favoring Colorado, and to a lesser extent, Southern California and the Southwest U.S. The East will see a gradual warming trend with snow continuing to favor the Great Lakes region. The Northwest will finally start to see some snow at the end of the month.

Lake effect snow will continue to bring light snow accumulations to the northern Mid-Atlantic on Friday and this weekend. Snow will be heaviest Saturday afternoon through Sunday morning with 5-10+ inches in western NY. Light snow of 1-6 inches will fall in central NY and the higher terrain of the western Mid-Atlantic. More chances of snow north and west will occur to start next week.
