High pressure built on either coats early Monday, while a strong storm system moved from the Rockies into the Plains.

Snow was to linger across the Great Basin and northern Rockies through the morning hours, but taper off in the afternoon.

To the east, a cold front associated with the storm will trigger heavy rain and strong thunderstorms throughout the Plains. Precipitation along the length of the front will be bolstered by the remains of Hurricane Norbert which crossed Mexico and pushed into the Southwest on Sunday. The storm lost all of its strength, but will continue to carry additional moisture into the region.

By evening, the storm was expected to push into the western Great Lakes region where more rain and thunderstorms were anticipated.
