The nation's weather

An early season winter storm will continue to pummel the Northeast on Sunday as it moves northeastward and exits the region by Sunday evening.

The strong storm will continue drawing Atlantic Ocean moisture while cool air from Canada filters in behind the system, triggering snow showers across New England and into Nova Scotia by evening.

Heaviest snowfall is anticipated early Sunday from Vermont to Maine with snowfall rates up to 2 inches per hour possible, especially at higher elevations. Snowfall accumulation will be significantly less than Saturday, with most areas seeing 2 to 5 inches of snow. However, higher elevations may see up to 8 inches Sunday.

Behind this system, high pressure will quickly build across the Eastern half of the nation, bringing drier conditions. The Plains and Mississippi River Valley will start to warm up as flow from the south returns. Expect the Southern Plains, Lower Mississippi River Valley, and Tennessee Valley to return to the mid-60s, but the Northeast and Mid-Atlantic states will remain in the 40s.

In the Midwest, a low pressure trough and associated frontal boundary continue moving eastward from the Northern Plains through the Great Lakes. This system will trigger a few light and scattered rain showers as it moves through the Midwest throughout the day.

Out West, another cold front moves into British Columbia and the Pacific Northwest. This will bring more rain showers to Oregon and Washington, with high elevation snow showers in the Cascades. Temperatures in the lower 48 states ranged Saturday from a morning low of 10 degrees at Mt. Washington, N.H., to a high of 87 degrees at Fort Lauderdale, Fla.
