The nation's weather

Much of the eastern third of the U.S. will see precipitation Saturday as a major storm strengthens as it moves from the Ohio Valley into the Northeast. As the storm treks eastward, it will pick up abundant moisture from the Gulf of Mexico and spread ample rain east of the Mississippi Valley and across the Appalachian Mountains. Thunderstorms will shadow the main cold front into the East, some of them possibly turning severe in the Southeast.

In colder New England climes, some of this precipitation will fall as snow and breezy, windy conditions are in the forecast for many areas of the Northeast.

Cold air will filter into the Plains, keeping temperatures cool to cold.

In the West, a Pacific storm will gradually move inland, producing rain and high elevation snow from Northern California through the intermountain West. This storm will move slowly southward as the weekend progresses.

Temperatures in the Northeast will rise into the 40s and 50s, while the Southeast will see 60s and 70s. The Northern Plains will have readings in the 0s and 10s, while the Northwest will see temperatures in the 30s and 40s. Temperatures in the lower 48 states Friday ranged from a morning low of -26 degrees at Clayton Lake, Maine, to a high of 86 degrees at Laredo, Texas.
