The nation's weather

The Western U.S. remains cool and windy Friday, while showers move into New England.

A low pressure system that brought heavy snow to the Sierras and Cascades, thunderstorms to southern California and strong winds to the Southwest will continue moving eastward over the Rockies on Friday. The system will produce 2 to 5 inches of new snow over the Northern and Central Rockies, while heavy rain will develop across Arizona and New Mexico. Some lingering snow showers are expected across the Sierras with accumulation around 2 inches. Strong winds will also persist across the region with gusts up to 45 mph again. Behind this system, strong flow from the north will create cool spring weather across the West Coast. High temperatures are expected to range between 10 and 15 degrees below seasonal, with highs in the 40s and 50s across most of California.

Meanwhile, in the East, a trough of low pressure pushes a cold front through the Midwest and up the Ohio River Valley into the Northeast. This system will continue producing scattered showers as it slowly moves eastward. This system is capable of producing isolated thunderstorms in the afternoon and evening hours, but severe thunderstorms are not likely. Rainfall totals will remain light, with up to a half of an inch in areas of thunderstorm activity. Some of these showers and thunderstorms may extend southward, edging toward the Gulf and Mid-Atlantic states. Temperatures will remain more seasonal on the Eastern side of the country, with highs in the 50s in the Northeast, to the 80s in the Southeast.

Temperatures in the Lower 48 states Thursday ranged from a morning low of 5 degrees at Mt. Washington, N.H., to a high of 92 degrees at Edinburg, Texas.
