Weather Underground Forecast for Saturday,April 9,2016

An area of low pressure will move over the Southwest on Saturday, while unseasonable cold conditions persist across the Northeast.

A Pacific low pressure system will shift slowly eastward across southern California. This system will interact with subtropical moisture over the region, which will lead to moderate to heavy rain and isolated thunderstorms across southern California and portions of the Desert Southwest. By the second half of the day, wet weather will shift north and eastward over northern California, the southern tier of the Pacific Northwest and portions of the Intermountain West. High elevation snow is expected for the Sierra Nevada, the Wasatch and the Rockies. In addition, subtropical moisture drifting over the southern Plains will bring chances of scattered showers and thunderstorms to Texas, Oklahoma and Arkansas.

Meanwhile, an arctic air mass will remain in place across the eastern half of the country. Temperatures will be 10 to 20 degrees below average for many states across the Midwest, the Mid-Atlantic and the Northeast. Accumulating snow is expected for the upper Midwest and the central Appalachians, while mixed precipitation affects the Mid-Atlantic and New England.
