The nation's weather

[January 28, 2011] (AP) Expect more wintry weather across the northern U.S. as another series of low pressure systems move in from the north Friday.

A low pressure system and associated cold front that kicked up light snow over the Great Lakes will continue moving eastward and move up the Ohio River Valley into the Northeast. This system has little moisture associated with it, so is not expected to bring significant snow to the Northeast. Snowfall totals will remain light, with accumulation ranging from a dusting to an inch. Higher elevations of the Virginia may see up to 3 inches of snowfall.

This will be a nice and short break from significant snowfall for the Northeast and New England, as another low pressure system dips in from Canada shortly behind this system. Also known as an Alberta clipper, the system will dip into the upper Midwest from Saskatchewan. As this system creates a cold front that stretches to the south, it will kick up 1 to 3 inches of snow as it sweeps through Minnesota and Wisconsin, then quickly moves over the Great Lakes. High temperatures across the northern U.S. will remain in the 20s and 30s.

In the South, a ridge of high pressure builds over the Gulf of Mexico and will bring dry and mild weather to the southeastern U.S. Expect highs ranging in the 60s and 70s under mostly sunny skies.

In the West, a dominant ridge of high pressure over the West Coast will bring more warm and dry weather to California and the Southwest. However, a trough of low pressure moves into the Pacific Northwest from a low pressure system in the West, allowing for widespread scattered rain showers to develop across western Washington and Oregon.
