A Cold Weekend Chicago to NYC
A press of cold air will drive southward late this week from the Upper Midwest to the interior mid-Atlantic and New England this weekend.
While the cold push will not last long, it will feel like winter for a few days.
Temperatures may range from 5 to 10 degrees below normal for a two- to three-day stretch from Minnesota, Iowa and Illinois, eastward to Maine, New York and Virginia.
The cold flow over the warm waters of the Great Lakes will set off lake-effect snow, but probably not in traditional areas.
Surface winds will be from the north and northeast and could create some interesting bands of snow on the west side of lakes Michigan and Huron, over north-central Ohio from Lake Erie and between Buffalo and Rochester in New York off Lake Ontario.
The northerly flow of air over the open waters of the Great Lakes will negate the magnitude of the cold over the Ohio Valley states. However, in portions of northern upstate New York and northern New England, it can get mighty cold for a couple of days, since the air will not take a route over the Great Lakes first.
Farther south along the I-95 corridor, the cold press will be less pronounced, delivering near-normal temperatures (highs in the 30s) for a couple of days, rather than the 40- and 50-degree stuff.
A swath of light and generally insignificant snow will run eastward during the middle of the week, well ahead of the main cold push coming late in the week.
As colder air pushes into the Northeast this weekend, it is possible that more than just a few wind-blown flurries are produced in some locations. Concerns range from a swath of a few inches of snow in part of the mid-Atlantic to a snowstorm for part of New England.

Hail is much more common during the months of May and June compared to July and August. The main reason is the fact that the freezing level is usually higher during July and August as pockets of cold air in the upper atmosphere are less common as the jet stream weakens and retreats farther north.
