Weather Underground Forecast for Sunday, November 04, 2012.

Expect more rain showers across parts of the Pacific Northwest, while showers and thunderstorms will move into the Southeast on Sunday. A trough of low pressure will move eastward from the center of the nation and will continue pushing a cold front eastward through the Southeast. This system will pull some moisture onshore from the Gulf of Mexico, allowing for scattered showers and thunderstorms to develop from eastern Texas, over the Lower Mississippi River Valley, and eastward into the Carolinas. While strong winds and periods of heavy rainfall are likley, severe thunderstorm development is not anticipated across the Southeast. North of this system, dry and sunny conditions will return to the Northeast as higher pressure builds into the region.

In the Northern Plains, expect another cool day with a combination of rain and snow showers as another trough of low pressure drops southward from central Canada. This will allow for a few overnight and early morning snow showers to develop over North Dakota, which will turn to rain showers during the daytime. This messy combination of snow, freezing rain, and rain will create dangerous roads and travel conditions across the region.

Meanwhile out West, a trough of low pressure moving into British Columbia will extend into far western Oregon and Washington. This will produce a few more rain showers, but most of the precipitation from this system will remain to the north in British Columbia.

Temperatures in the Lower 48 states Saturday have ranged from a morning low of 12 degrees at Gunnison, Colo. to a high of 91 degrees at Edinburg, Texas
