Dry, Less Humid Air Heading for Great Lakes, Appalachians

Less humid and rain-free weather is expected to move into the Great Lakes region and much of the Northeast towards the end of the week and into the weekend.

A storm system in Canada will drag a cold front through the region, ushering in a drier and more comfortable air mass.

Areas around the Great Lakes to the Appalachians will notice the biggest difference in humidity levels while areas along the coast might not be as lucky.

As the front advances to the coast, it may slow down and potentially even stall, limiting the amount of relief for areas from Boston to New York City, Philadelphia, Baltimore and Washington, D.C.

The drier air may have a tough time moving into these areas and the risk of a spotty shower or thunderstorm will remain with the front stationed nearby.

Folks that are most sensitive to high humidity may feel some relief, but for most, the subtle changes early in the weekend may go unnoticed.

As for places farther west, an area of high pressure is expected to form over the Midwest and slide eastward through the weekend providing sunnier skies and a break from the rain for areas around Detroit, Cleveland, Pittsburgh, Buffalo, Burlington, Vt., Albany, N.Y., Scranton, Pa., Hagerstown, Md., and Charleston, W.Va.

In Toronto, conditions will improve, which will be greatly welcomed after Monday's drenching storms. Pearson International Airport received 4.96 inches of rain (126 mm), making it the rainiest day ever for the city. The old record was during 1954's Hazel.

Places towards the coast, such as New York, Philadelphia and Washington, D.C., may eventually experience improving conditions, if the area of high pressure slides eastward and the front slowly pushes off the coast during the course of the weekend.

It has been a wet summer so far for much of the region and any kind of relief from rain and high humidity will be welcomed by most.
