A Pacific storm that moved over the West Coast on Saturday will continue moving inland Sunday, producing high-elevation snow through the Northern Rockies. By Sunday afternoon, this storm will begin to pull into the Plains, increasing precipitation in Kansas and Nebraska.
Late in the day, yet another wet Pacific storm will slam into the Northwest coast, bringing rain and high-elevation snow from Washington state through northern California. This has been a very wet March for the Golden State, but Sunday may be the end to the precipitation for a few days.
Farther to the east, a spring storm will develop in the Southeast, pulling considerable moisture northward from the Gulf of Mexico. This moisture will translate to widespread thunderstorms and rain through the Southeast late in the day and into Monday.
The Northeast will remain cool with temperatures in the 30s, while the Southeast will see temperatures that range from the 50s to the 80s. Temperatures in the Southern plains will rise into the 80s and maybe even some 90s, while the Northwest plains will see temperatures in the 20s and 30s. The Northwest will rise into the 30s in the higher elevations and into the 40s and 50s elsewhere. Temperatures in the Lower 48 states Saturday have ranged from a morning low of -13 degrees at Tomahawk, Wis. to a high of 90 degrees at Laredo, Texas.
