The nation's weather

[January 04, 2011]  (AP)  The West will see another chilly day, while scattered snow showers develop across the Great Lakes on Tuesday.

A trough of low pressure that brought light snow to the northern Plains and upper Midwest will continue making its way eastward and toward the northeastern U.S. The system will continue pushing a front eastward with it, which will trigger snow showers as it moves over the Great Lakes. Snow showers will remain light as this is a relatively weak system and has little moisture associated with it. However, the eastern shores of the Great Lakes may see periods of heavy lake-effect snowfall as flow from the west picks up additional moisture from the Great Lakes. Expect most areas to see between 1 to 3 inches of snow, while areas along the shores may see up to 5 inches of snow.

In the South, expect another dry and mild day as high pressure dominates from the southern Plains to the Southeast and Mid-Atlantic states. This will allow for seasonable temperatures with highs in the 60s and 70s. Clear skies will also create chilly nights with overnight lows dipping into the mid-30s.

In the West, California will finally dry out as a low pressure system offshore diminishes. High pressure over the West Coast will bring a sunny day while flow from the north will push in more cold air. Expect highs to range from the 30s to 50s across the West Coast. Freeze advisories have been issued over the coastal regions of the Pacific Northwest as overnight lows dip into the upper 20s again Tuesday night. Another cold front was approaching the region, produced by a low pressure system in the Gulf of Alaska. This system will bring increasingly cloudy skies to Washington state, but precipitation will remain to the north in British Colombia on Tuesday.

Temperatures in the Lower 48 states Monday ranged from a morning low of minus 32 degrees at Bigfork, Minn., to a high of 79 degrees at Hollywood, Fla.
