After a brief cooldown late this week, very warm and humid air will bounce back during the Labor Day weekend.
The pattern will be a boost for outdoor summer activities ranging from swimming to cookouts and ball games. Cristobal will have moved well off into the North Atlantic by this weekend, which will allow seas and surf to diminish.
However, seas will get stirred up some again along the mid-Atlantic and Northeast beaches with a moderate rip current threat for a time Sunday through early Monday.
In terms of comfort and dry weather, Saturday will be the best of the three days this weekend.
High temperatures will flirt with or crack the 90-degree mark from Washington, D.C., to Philadelphia and New York City on Sunday and Labor Day. The warmth will be accompanied by a surge in humidity levels and an increasing risk of showers and thunderstorms.
The combination of temperature, humidity, sunshine and other conditions will drive AccuWeather RealFeel® temperatures well into the 90s to near 100 for several hours from the late morning into the afternoon.
People spending time outdoors may have to dodge some rainfall. Spotty thunderstorms are in the offing this weekend in the East, but it should only rain a small fraction of the time.
The bulk of the shower and thunderstorm activity will hold up from the Appalachians to the Midwest through midday Sunday. The best chance of a downpour reaching the I-95 corridor and the beaches is Sunday afternoon and Monday.
While temperatures will fluctuate from one day to the next and will be dependent on the amount of shower and thunderstorm activity, chilly air will not be in a hurry to move in during September.
People in the I-95 East may not want to close the pool or put the air conditioner away just yet.
According to AccuWeather Long-Range Expert Paul Pastelok, "The pattern through the first half of September in the East will generally favor more days with above-average warmth, than days with below-average warmth."
Pastelok expects a push of chilly air to build southeastward from Canada around the third week of September.
"Ahead of that push may be a surge of very warm air into the East during the second week of the month."
The pattern may guide some tropical systems that develop in the Atlantic toward the southern part of the United States, the Caribbean and Mexico.
Storms that may hinder any outdoor plans on the last weekend of official summer will interrupt an otherwise calm stretch of weather with sunny skies.
