The nation's weather

Wet weather will move into the central U.S. on Wednesday, as a trough of low pressure moves into the Plains from the Rocky Mountains.

A trough of low pressure in the East will pull eastward and away from the East Coast. This will bring an end to rain, freezing rain, and snow showers over the Central and Northern Appalachians and the Northeast. In parts of upstate New York, lake effect snow showers will persist along the downwind shores. In the South, a cold front extends southward from this system and pushes off the coast of the Mid-Atlantic states. This front will linger over Florida and southern Georgia, triggering widespread showers and thunderstorms. Some of these storms may turn severe as it moves into the Lower Mississippi River Valley. Rainfall totals will vary around an inch, with up to 2 inches likely in areas of thunderstorm activity. Expect strong winds and large hail to accompany this system. The northern edge of this system remains cooler, which will allow for snow showers to develop across the Northern Plains and Upper Midwest. Snowfall accumulation will be light in most areas.

In the West, a low pressure system slides through the Pacific Northwest, over northern California, and into the Great Basin. This will produce gusty winds with rain and high elevation snow showers as it passes southeastward throughout the day. Temperatures in the Lower 48 states Tuesday have ranged from a morning low of -22 degrees at Presque Isle, Maine to a high of 79 degrees at Harlingen, Texas.
