Midweek Heat to Be Temporarily Erased in NYC, DC, Boston

After several days of summerlike warmth, a push of cooler and more pleasant air will greet folks in the Northeast to end the week.

A cooler and more comfortable air mass originating out of Canada will be on the heels of a cold front that will slowly drift across the region through Friday.

A drop in temperature and humidity due to this new air mass will bring about a rather pleasant end to the week across the eastern Great Lakes, New England and mid-Atlantic.

The air mass will not provide a deep chill in relation to August standards, but temperatures will be noticeably cooler in the wake of the recent warm stretch.

"It's not going to get anywhere near as cool as it was in other episodes earlier this summer," said AccuWeather Senior Meteorologist Elliot Abrams.

High temperatures will likely bottom out in Pittsburgh, Buffalo, and other locations west of the Appalachians on Thursday. Meanwhile, Washington, D.C., Philadelphia and Boston will likely have their coolest day on Friday.

People who may have outdoor activities scheduled on Thursday and Friday will find the weather to be very cooperative.

High pressure will influence the region and will help keep precipitation and most clouds away.

Beachgoers may find the weather to be perfect but are urged to use caution if they head to the water. Cristobal, although staying well away from coast, will produce dangerous rip currents and rough surf.

Folks are reminded to apply sunscreen if they are planning on being outside for extended periods of time. Even though summer is on the wane, the sun's ultraviolet rays are still rather strong.

Although the bulk of the summer has been on the cooler side, the beginning of the week gave folks across the region a taste of the summertime steaminess that they've mostly missed out on this season.

High temperatures climbed into the upper 80s to near 90 in many locations on Tuesday. An uptick in humidity accompanied the warmth, making it feel more like the middle of summer.

Temperatures on Wednesday are forecast to hit 90 in several Northeast cities, something that hasn't occurred as often this summer as it normally does.

New York City has only had four days with temperatures reaching or exceeding 90 degrees, an occurrence that typically happens 12 times a summer.

That number will not be increasing for the end of the week as high temperatures dive down into the upper 70s to lower 80s.

The cool and dry spell will only last a couple days. "It looks like warmer weather will take over for Labor Day weekend and into early next week," added Abrams.

Steamy air is set to move back in for the holiday weekend with thunderstorm chances increasing.
