A Pacific storm will gradually move onto the West Coast on Sunday, renewing rain and high elevation snow from Washington through northern California. The heaviest precipitation will fall along the coast, while areas as far inland as western Montana will experience showers. As the main cold front moves ashore, cool temperatures will prevail along the West Coast.
Farther to the east, a developing storm will move out of the Rockies and into the Plains. As it moves east, it will pick up moisture from the Gulf of Mexico that will translate to increasing rain from eastern Texas through southern Illinois. Rain and some thunderstorms will spread eastward Monday into the Tennessee Valley.
In the Northeast, scattered snow showers will taper off as the day progresses, leading to dry conditions early Monday.
Northeast temperatures will rise into the 30s and 40s, while the Southeast will see readings in the 60s and 70s. The southern Plains will rise into the 70s and 80s, while the northern Plains will see temperatures in the 20s and 30s. The Northwest will rise into the 30s, 40s, and 50s.
Temperatures in the lower 48 states Saturday ranged from a morning low of 1 degrees at Thief River Falls, Minn., to a high of 89 degrees at Pecos, Texas.
