[November 13, 2010] (AP) A strong low pressure system was slowly moving eastward through the central U.S. on Saturday.

The cold front associated with this low pressure system was expected to sweep over the Mississippi River Valley. This system was obtaining ample moisture from the Gulf of Mexico, and was forecast to be capable of triggering some heavy rains with strong downpours.

Rainy conditions were expected to stretch from Illinois and Indiana down the Mississippi River Valley into the Gulf states. Expected rainfall totals ranged between 1-2 inches in most areas.

The northern side of this system was forecast to keep pulling cold air in from Canada. As this system takes what was expected to be a more northeastern path, it was forecast to bring more snow to the upper Midwest.

A winter weather advisory was issued for parts of Minnesota and Wisconsin, as snow accumulations may range between 5 and 8 inches. This was forecast to bring dangerous road and travel conditions throughout the day as slow and continuous snowfall was expected. Highs in the Midwest and northern Plains were forecast to remain in the 30s, while the southern Plains were expected to see highs in the 50s and 60s.

In the East, or ahead of the front, southerly flow was expected to keep pushing in some warmer air. Thus, the East Coast was forecast to remain slightly warmer than seasonable on Saturday. High pressure was expected to prevail so another sunny day with highs in the 60s was forecast across New England.

Out West, another trough of low pressure in the Pacific Ocean was pushing a cold front over the Pacific Northwest. This was expected to trigger more showers over Oregon and Washington, with snow developing across the northern Rockies. Snowfall totals were forecast to be light, with near an inch likely.

Temperatures in the Lower 48 states Friday ranged from a low of 3 degrees at Alamosa, Colo., to a high of 82 degrees at Port Isabel, Texas.
