After drenching rainfall fell across the Northeast on Thursday, the next storm system will bring another round of rain and chilly conditions this weekend.
"While it seems the Northeast has been locked into above-normal warmth for the past few weeks, the coming storm this weekend will bring a much more comfortable air mass to the region," AccuWeather Meteorologist Evan Duffey said.
While there will not be the threat for any widespread severe thunderstorms across the Northeast, rain will be heavy at times.
Many locations across the Northeast will still be drying out after a soaking rainfall on Thursday. Some locations received more than their normal rainfall for the entire month of September in only one day.
City, State | Rainfall (inches) | City, State | New Record |
Philadelphia, Pa. | 4.76* | JFK Airport, N.Y. | 1.18* |
Harrisburg, Pa. | 4.37* | LaGuardia, N.Y. | 1.04 |
Islip, N.Y. | 2.30* | Newark, N.J. | 0.98 |
Trenton, N.J. | 1.90* | Hartford, Conn. | 0.86 |
Central Park, N.Y. | 1.58* | Providence, R.I. | 0.77 |
Allentown, P.A. | 1.43 | Pittsburgh, Pa. | 0.24 |
Reading, P.A. | 1.40 | Boston, Mass. | 0.17 |
Bridgeport, Conn. | 1.26 | Washington, D.C. | 0.11 |
Rainfall amounts could reach up to 2 inches in places this weekend. Any additional rainfall in the hardest hit areas from earlier this week could lead to localized flooding issues.

A dip in the jet stream will also lead to chilly conditions across the Northeast through the weekend.
"Temperatures in the Northeast really won't get far below normal, especially along the Interstate 95 corridor, but the difference between the recent air mass and the new one over the weekend will feel noticeable cooler," Duffey said.
While high temperatures will remain seasonable along the Interstate 95 corridor, the interior portions of the Northeast including State College, Pennsylvania, Pittsburgh; Charleston, West Virginia; and Syracuse and Buffalo, New York, will fail to get out of the 60s Fahrenheit this weekend. Average high temperatures across the Northeast are typically in the 70s F by the middle of September.

"Temperatures will fall below normal across the Great Lakes and lead to the possibility of lake-effect showers," Duffey said. "A waterspout or two over the Great Lakes is not out of the question this weekend."
High pressure will build across the eastern U.S. early next week and bring a stretch of dry, pleasant weather through late in the week. Temperatures will slowly moderate each day next week, but not to the extreme heat from the week before.
