Chilly air sweeping across the Midwest and Northeast will allow thundershowers with hail in some areas and the return of snow to other locations during the middle of the week.
Part of Interstate-95 Corridor May Receive Hail Wednesday
Following a sunny start, colder air moving in aloft will allow clouds and showers to develop in part of the Interstate-95 corridor on Wednesday.
According to AccuWeather.com Senior Meteorologist Alex Sosnowski, "Areas from Washington, D.C., to New York City and Hartford, Connecticut, could experience a brief thundershower during the midday and afternoon hours on Wednesday."
The thundershowers are most likely to occur where the sun is out for a few hours during the morning hours, which will allow temperatures to climb into the 60s.

"While the storms are not likely to be severe, some areas of the mid-Atlantic states to southern New England can be hit with a gusty thundershower that delivers small hail," Sosnowski said.
As chilly air works its way down to the surface, snow showers will expand from the Great Lakes to the interior Northeast later Wednesday and Wednesday night.
The rapidly changing weather conditions may catch some people off guard. As the drenching showers and thundershowers sweep through, temperatures will be slashed by 15-20 degrees in a matter of minutes.
Midweek Snow to Coat Upper Great Lakes to Northern Appalachians
Farther to the northwest, where colder air has taken root, snow showers will continue to pivot southeastward across the upper Great Lakes, including Marquette, Michigan, through Wednesday.

According to AccuWeather.com Meteorologist Steve Travis, "Rain showers will spread [southeastward] across the region during the day Wednesday, then as temperatures fall to near freezing Wednesday night, some snowflakes will mix in."
Wednesday night is the most likely time for wet snow to be seen over parts of the central Appalachians to northern New England. Snowflakes can fall as far south as the West Virginia mountains, and as far east as the Poconos, Catskills and Berkshires.

"Most places will not see any accumulation; however, a few areas over higher elevations could pick up a coating on grassy surfaces," Travis said.
The areas with the greatest chance for a coating of wet snow will be across the northern and Upper Peninsula of Michigan and the Adirondack, White and Green mountains.
Due to the recent warm spell across the region, any snowflakes that fall will quickly melt on roadways with no accumulation expected, even if temperatures dip a couple degrees below freezing.
