Another round of cold temperatures and winter snow showers greeted those in the East early Monday, while rain was in store for the Southeast and clear skies dawned over the West.

Several areas of low pressure will produce a mix of rain and snow showers across the Great Lakes, Northeast and the mid-Atlantic.

Beginning in the North, an area of low pressure located over the Great Lakes will advance eastward into the Northeast by the afternoon. As the system progresses, it will pull cold northern air across the warmer lake waters to produce moderate lake-effect snow bands across areas of northwestern Indiana, Michigan and the lower Great Lakes.

To the east of this system, another area of low pressure will produce significant snow shower activity across New England. This winter storm system is expected to produce up to 5 inches of snow as it moves over eastern Maine.

A third low pressure system was expected to produce mixed precipitation across the Ohio Valley and mid-Atlantic. Light rain showers will develop along an associated cold front as it sweeps through the Southeast.

The West was expected to remain dry due to a strong high pressure system, producing fair conditions with above normal temperatures across California and the Southwest.

Temperatures in the Lower 48 states on Sunday ranged from a low of minus 30 degrees at Caribou, Maine, to a high of 87 degrees at Santee, Calif.
