The nation's weather

Active weather will linger in the West on Sunday, while the eastern U.S. remains sunny and dry.

A low pressure system in the Gulf of Alaska continues pushing waves of low pressure over the western U.S., creating disturbed weather. The system that brought snow to the Rockies will advance northeastward and move over the Northern Plains and into central Canada on Sunday. Temperatures will remain above freezing, mainly producing rain showers. However, the back side of this system will pull in cool air from the North and churn up a wintry mix of rain and snow over western North and South Dakotas.

A cold front extending southward from this system will spread over the Upper Midwest and into the Mid-Mississippi River Valley. This will kick up some light and scattered rain showers by evening. The tail end of the frontal boundary will reach into the Southern Plains, where it will obtain energy and moisture from the Gulf of Mexico. Expect some scattered thunderstorms across Oklahoma and Texas.

In the East, a large high pressure ridge is the dominant weather feature for the eastern third of the nation. This will create another dry and sunny day, allowing the gradual warming trend to continue.

The Northeast will see highs in the mid-50s, the Ohio River Valley will remain in the 60s, and the South will approach the 70s. Temperatures in the lower 48 states ranged Saturday from a morning low of 1 degrees at Winnemucca, Nev., to a high of 84 degrees at McAllen, Texas.
