LONG ISLAND, NY – AccuWeather reports after powerful thunderstorms struck the Northeast early in the week, the weekend will end up soggy for many with flooding also possible in some areas.
A storm system over Illinois and Indiana will become more organized Friday afternoon and set its sights on the Northeast for the weekend.
Saturday’s rain will mainly focus from southern Ontario to western New York and Pennsylvania, including the cities of Cleveland, Ohio; Buffalo, New York; Rochester, New York; and Pittsburgh and Erie, Pennsylvania.

The heaviest rain is expected Saturday night, shifting from western Pennsylvania to central New York and to the I-95 corridor from Boston to Washington, D.C.
Outdoor events this weekend ranging from camping trips and weddings to pool days could require alternate planning. Baseball games from Friday evening through Sunday afternoon could have rain delays. This includes three home games for the Pittsburgh Pirates against the Braves at PNC Park and games Saturday and Sunday at Citi Field, as the New York Mets take on the Cincinnati Reds.
With this persistent rain, some downpours will also be possible, bringing the risk for flooding.
“With the slow-moving nature of this system and its gradual strengthening, heavy rain is inevitable,” AccuWeather Meteorologist Evan Duffey said.
“Through Saturday and Sunday, a swath of 1 to 2 inches (25 to 55 mm) will be across the Northeast, with locally higher amounts,” Duffey said.
With rainfall totals of this magnitude, some flooding problems may occur.
“We do not expect widespread flooding but more rather small stream flooding in south-central and southeastern Pennsylvania,” Senior Hydrologist at the National Weather Service Middle Atlantic River Forecast Center Scott Kroczynski said.
Heavy rain is likely to fall farther to the west over Pennsylvania, parts of Ohio and western New York. These areas have the potential for flash, urban and small stream flooding.
Flooding on roadways and poor drainage areas is also possible in the heaviest rain. Some major highways where traffic could be affected by downpours in this rainstorm include I-70, I-79, I-80, I-81, I-86, I-88 and I-90 during Saturday and Saturday night. Eastern parts of I-90 and I-87 will have more travel delays Saturday night into Sunday.
By late Sunday afternoon, the heavy rain storms should pass resulting in much cooler temperature which will assist in ending the massive heat wave occurring in the Southeast. Photo: AccuWeather.
AccuWeather Chief Meteorologist Elliot Abrams explained that this rain comes as nature’s way of balancing out the persistent dry weather in the West.
“This setup will end the extreme heat wave that has been baking the Southeast,” Abrams said.
He further explained that the shape of the system in the Northeast and its exact track could make the difference between widespread flooding and just cooler conditions with showers and thunderstorms.
With the track of the system now shifting farther north, the weekend looks like heavy rain will pass through in addition to a more refreshing air mass for much of the East Coast by late Sunday.
