 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
the front 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 ranged from a morning low of
minus 22 degrees at Presque Isle, Maine, to a high of 79 degrees at Harlingen, Texas.
