Week to End Dry, Cool in Philly, DC, NYC

After a drenching past few days, much of the Northeast will turn dry and cool for the end of the week.

A push of dry Canadian air will put an end to the flooding rain that targeted much of the mid-Atlantic and New England the past few days.

A breezy northwesterly wind will form in the wake of the departing storm system, ushering in dry Canadian air over the next couple of days. Some sunshine will return in many places that have been left underneath the clouds lately.

However, with cool air flowing in aloft, the sunshine could create enough instability to set off spotty showers Thursday and perhaps Friday, although most folks should remain dry.

Cooler air will accompany the dry push. High temperatures are expected to be 5 to 10 degrees below normal for many locations, perhaps even close to 15 degrees for some.

Light jackets and sweatshirts will need to be pulled out of the closet at night. Temperatures will drop into the 40s across the interior Northeast, readings that are typical for late September. Meanwhile, much of the I-95 corridor will see lows in the 50s to around 60.

The arrival of dry air will certainly be seen as a relief for most, after many communities were submerged in water over the past few days.

A rather potent storm system and cool front brought widespread torrential rainfall to many places, shutting down major highways and shattering rainfall records.

Some of the worst flooding occurred in or near major cities such as Detroit, Michigan; Baltimore, Maryland; New York City, New York; and Portland, Maine.

Detroit and Baltimore were the target for flooding rains on Monday and Tuesday. Several major highways in and out of the cities were shut down as high water turned them into rivers and lakes. Water levels could be seen approaching the rooftops of cars.

The morning commute deteriorated rather quickly across Long Island on Wednesday as heavy rain quickly filled up streets and roadways. The Long Island Expressway was shut down as high water stranded motorists. Several water rescues were conducted by local fire departments.

The rainfall gauge at Islip recorded 13.57 inches of rain, shattering the New York state 24-hour precipitation record.

The system responsible for the flooding rain is now gone from the Northeast, turning its focus on eastern Quebec and the Canadian Maritimes for Thursday. However, the system will weaken as the week closes, producing lower rainfall amounts.

Despite morning fog, Friday and Saturday will be rather pleasant across the I-95 corridor and mid-Atlantic.

For those who may have been stuck inside due to the recent soakings, the next several days should provide great weather for outdoor activities.

However, unsettled weather will return to the region late Saturday and into Sunday. Another storm system will begin to move in from the west.
