A few showers and thunderstorms will continue along the East Coast on Tuesday as a lingering coastal system impacting the area moves further offshore into the western Atlantic Ocean. Waves of low pressure along this disturbance will send moisture from the Atlantic back to the coast, allowing generally light to moderate showers and isolated thunderstorm to continue along the Southeastern and Mid-Atlantic coasts. This activity is expected to spread to the coastal New England areas as the northern wave of low pressure lifts into the offshore Atlantic waters of the Northeast. Meanwhile, the southern portion of this disturbance will linger across the Florida Peninsula with chances of showers and thunderstorms.

Behind this activity, high pressure building into the East will bring clearer skies, light winds, and drier air to much of the region. Areas from the Lower Ohio Valley into the Northeast will start the morning with chilly temperature near the freezing mark and will remain under a variety of Frost Advisories and Freeze Watches and Warnings through the early morning.

In the Midwest, a storm system skirting in the north-central part of the nation will advance into the Upper Midwest on Tuesday with areas of light to moderate precipitation. Much of the north-central U.S. will see a return to colder temperatures on Tuesday as high pressure from the north builds in behind this system with a colder airmass. Colder temperatures in the region will allow for a mix of rain and snow to develop in the Northern Rockies and Northern High Plains.
