A strong autumn storm will slam into the West Coast on Sunday, providing widespread moderate and heavy rain along with some high elevation snow through the Northwest, northern California, and the Intermountain West. This storm could produce sustained rain that may cause some localized flooding, especially in northern California. Winter storm warnings were in effect for the Sierra Nevadas and Cascades, where up to 2 feet of snow will fall.
The storm will also generate strong winds. Wind advisories are in effect for parts of northern California, Nevada, and southern Oregon in anticipation of gusts up to 60 mph. In the highest elevations of the Sierra Nevadas, gusts may be up to 120 mph.
As the storm moves inland, precipitation will spread through the Great Basin and Rockies.
Another storm will move into the Upper Midwest, bringing rain and thunderstorms from the Southeast through the Upper Midwest. Some of the thunderstorms in the Southeast may be severe enough to cause hail and wind damage.
Temperatures in the Northeast will rise into the 40s, 50s, and 60s, while the Southeast will see temperatures in the 70s, 80s, and some 90s. The Southern Plains will rise into the 80s and 90s, while the Northwest will see temperatures in the 40s and 50s.
Temperatures in the Lower 48 states Saturday ranged from a low of 22 degrees at Stanley, Idaho, to a high of 92 degrees at Falfurrias, Texas.
