A strong storm roaring along the West Coast was forecast to bring more rain and high elevation snow to the region, while heavy rain was expected across the eastern part of the country and the North was predicted to remain cold.

The storm that slammed the West Coast on Saturday was continuing its trek eastward, moving into the Great Basin. Widespread rain and high elevation snow was forecast from California through the Rockies and into the Intermountain West. It was to taper off as the day progresses.

Meanwhile, moist airflow from the Gulf of Mexico into the Southeast was expected to continue producing widespread moderate to heavy rain. Precipitation, including a mixture of rain and snow, was forecast to develop in the upper Mississippi Valley and parts of the Great Lakes.

As the day progresses, a developing front was predicted to sweep through the Northeast and Mid-Atlantic, allowing heavy precipitation to spread through the area. Snow was possible in northern New England.

The coldest air was expected to remain over the Northern Plains, where temperatures were likely to struggle to top zero. The Northeast was forecast to rise into the 30s and 40s, while the Southeast was to see temperatures in the 50s and 60s. The Northwest was expected to be in the 30s and 40s.

Temperatures in the Lower 48 states on Saturday ranged from a low of minus 15 degrees at Pinedale, Wyo., to a high of 85 degrees at Key West, Fla.
