Moderate rain and even some high-elevation snow would fall in northern California north of the San Francisco Bay Area. In addition, sloppy weather in the form of rain and high-elevation snow was expected to fall in Idaho and Montana. The storm would also allow cool air to sweep into much of the West, including the Southwest, where seasonably warm conditions had remained for the past few days.

A storm that brought wintry weather to coastal areas of New England on Sunday would continue moving northward along the coast and into the Canadian Maritimes. Thus, precipitation would diminish in New England in the early morning hours. Thus, a high pressure system anchored over the Southeast was expected to dominate the weather in the East. Dry conditions were expected in the eastern half of the country. Also, a pool of cold air was forecast to move off the eastern seaboard, allowing warmer air to move into the Southeast from the southern Plains.

The Northeast was expected to rise into the 40s and 50s, while the Southeast would see temperatures in the 60s and 70s. The southern Plains would rise into the 70s and 80s, while the Southwest would see temperatures in the 80s and 90s.

Temperatures in the Lower 48 states Sunday ranged from a low of 16 degrees at Grayling, Mich., to a high of 102 degrees at Mesa, Ariz.
