The nation's weather

More rain is in the forecast for the East on Sunday, while the West remains dry and warm. A nearly stationary low pressure system continues spinning over the Great Lakes and the Northeast.

While a slow-moving cold front will shove eastward and away from the East Coast, the system will produce another front that will move over the Midwest and Ohio River Valley. This will trigger more scattered showers and thunderstorms as it pulls moisture in from the Gulf of Mexico. The tail end of this system will stretch into the Ozarks, where the system may produce severe thunderstorms with strong winds, large hail and heavy downpours.

Out West, a large high pressure ridge continues to build over the Rocky Mountains and Plains. This will pull in warm air from Mexico and allow for some unseasonably warm temperatures across the central and northern Rockies. Daytime temperatures will approach record breaking highs, reaching into the 80s and 90s.

Meanwhile, a cold front associated with a low pressure system off the West Coast will advance onshore. This front is expected to scatter showers around the Pacific Northwest and northern California.

Temperatures in the lower 48 states ranged Saturday from a morning low of 26 degrees at Angel Fire, N.M., to a high of 102 degrees at Palm Springs, Calif.
