Weather Underground Forecast for Tuesday, Jan. 7, 2014

An area of moisture will push across the Great Lakes on Tuesday, while a high pressure system will usher below normal temperatures across the central U.S.

Moisture will push across the Great Lakes on Tuesday, triggering a lake effect snowstorm across the region. Heavy snow is forecast to impact portions of western New York and northwestern Pennsylvania, while widespread light snow can be expected across Michigan, the northern Ohio Valley and into the Northeast. Meanwhile, temperatures will drop 20 to 40 degrees below normal across the northern Plains, the upper Midwest and across the Mississippi Valley on Tuesday. The majority of the Gulf Coast and the Southeast will stay clear of wet weather, although an onshore flow from the Gulf of Mexico will initiate light rain across southern Texas. Similar conditions will push across southern Florida as well.

An area of low pressure will drive light snow showers across the northern and central Rockies on Tuesday, while a separate low pressure system will approach the Pacific Northwest. Light rain is forecast to push into northwestern California, western Oregon and western Washington, while high elevation snow will drive through the Cascades. The Southwest will stay clear of wet weather on Tuesday due to a ridge of high pressure along the eastern Pacific.

Temperatures in the Lower 48 states Monday have ranged from a morning low of -36 degrees at Crane Lake, Minn. to a high of 84 degrees at Immokalee Regional Airport, Fla.
