The nation's weather

Scattered showers and thunderstorms will continue developing across the Northeastern U.S., while the West will see some light precipitation Tuesday.

A low pressure system and associated cold front that brought heavy rain, strong winds, and some thunderstorms to the Eastern Valleys will continue triggering storms. The system will slowly push off the Mid-Atlantic and New England shore, but flow around the system will continue pulling moisture onshore, kicking up scattered showers and thunderstorms from the Tennessee Valley to the Northeast. If storms turn severe, they will most likely develop along the Eastern Seaboard.

Behind this system, a ridge of high pressure quickly sweeps through the Central U.S. This ridge brings sunny skies and above seasonal temperatures to the Plains and Midwest, but is pushed eastward by another incoming system. Highs will range in the 60s and 70s in the North, while the Southern Plains will remain in the 70s and 80s. A low pressure system moving eastward through Canada will push a cold front through the High Plains and into the Upper Midwest. This is expected to trigger a few rain and snow showers over the Northern Rockies and High Plains throughout the day. Meanwhile, the West Coast will see a mild day as a weak ridge of high pressure builds northward from the Southwest.

Temperatures in the Lower 48 states Monday ranged from a morning low of 10 degrees at Leadville, Colo., to a high of 95 degrees at Edinburg, Texas.
