What's Ahead This Week After Jonas

While much of the East is still digging out from Winter Storm Jonas, other parts of the country will see more snow this week. By midweek, a frontal system is expected to move toward the East Coast with rain and a touch of wintry weather. Will low pressure off the Eastern Seaboard be anything to worry about?

Before we look ahead to that, let's discuss a pair of other weather-makers at the beginning of the week.

First Snowmaker: Plains, Upper Midwest, Great Lakes

Low pressure will track from the Great Lakes into eastern Canada Tuesday.

Light snow will linger in the western Great Lakes Tuesday. In the eastern Great Lakes and parts of the interior Northeast, some rain and patchy freezing rain will change to light snow, and may linger into early Wednesday.

Additional snow accumulations should remain much less than 6 inches in most of these locations. The peak snowfall total so far early Tuesday morning was 5 inches in Appleton, Wisconsin.

Midweek Front: Rain Spreads Through the South

Rain showers will move from the lower Ohio Valley into parts of the Northeast and Mid-Atlantic. Although some light snow or ice is possible across the higher terrain of Pennsylvania, Upstate New York and northern New England, temperatures should rise into the 40s across the region, supporting mainly rain from this next round of precipitation.

Since rain is forecast to be fairly light, most of the fresh snowpack should be able to absorb the rainfall without any significant flooding concerns.

Forecast: Baltimore | Nashville | New Orleans

To the south, showers and a few rumbles of thunder will be possible from the Tennessee Valley to the Gulf Coast. The threat for any severe thunderstorms is fairly low, although a few storms could feature gusty winds and briefly heavy rainfall.

By Wednesday, the front sweeps off the East Coast, but stalls over the Florida peninsula. 

Across the Southeast, rain showers with temperatures rising into the 40s and 50s are expected. Warmer, somewhat unstable air across Florida may support a few thunderstorms, some of which could become severe.

A combination of snowmelt and some rainfall could lead to some ponding of water and spotty poor-drainage flooding in parts of the Appalachians of Virginia and North Carolina, but 

The front will linger across Florida and near the Southeast coast into Thursday bringing more rain along with potentially a few severe thunderstorms to Florida.

Late Week: Likely an East Coast "Near-Miss"

With the front located near or just offshore, a dip in the jet stream is expected to dig a trough of low pressure into the northeastern states at the end of the week. Low pressure should develop and intensify off the coast, especially if the approaching trough can catch up with the front.

If this "capture" of energy occurs too late or well offshore, then any coastal storm would likely pass out to sea, largely missing the Eastern Seaboard. This would result in few, if any, weather impacts along the East Coast. 

However, if low pressure gets pulled back closer toward the East Coast, then we could see some snow, a wintry mix or rain in portions of the Mid-Atlantic and Northeast. 

Mainly light snow is expected in the interior Northeast from Maine to Upstate, western and central New York to the Appalachians of Weste Virginia with a cold front Thursday night into Friday. The Interstate 95 corridor should only see gusty northwest winds behind the front, with little to no snow.
