NEW YORK (WABC) -- After severe flash flooding walloped parts of New York City and New Jersey Saturday afternoon, the rest of the day's storms were not nearly as wild, with a cold front finally ushering in a much nicer air mass.
With the last of the storms gone, Sunday will be sunny and less humid and will feature better air quality, the skies significantly cleansed of noxious Canadian wildfire smoke. There will still be enough particulate matter in the air to be a problem for sensitive groups.
Central Park saw 1.62 inches of rain, but some areas had more, with Newark reporting 2.38.
Now, under Sunday's clear skies, areas hard-hit by the storm's flooding must focus on cleanup, as the city's aging infrastructure once again endured another test.
Eyewitness News and ABC 7 for the latest.
Northeast Corridor and North Jersey Coast Line westbound rail service had to bypass the EWR station due to flooding conditions.
Eastbound customers are advised to transfer at Elizabeth station for eastbound service to EWR.
More than 1,000 flights have been cancelled and over 4,000 delayed due to weather across the Northeast. According to the FAA, thunderstorms impacting the New York and Philadelphia metropolitan areas have resulted in ground stops at major airports throughout the region.
Airports currently under a ground stop due to thunderstorms include, BOS, EWR, LGA, JFK, PHL, DCA, IAD and BWI.
Most impacted airports:
-LGA: 264 cancellations- flights out of airport seeing delays of about 4 hours

Drivers in Newark are asked to avoid the following locations due to the potential for flooding:
A Tornado Watch has been posted for parts of the area until 9 p.m. ET. Widespread damaging wind gusts up to 70 mph, and a few tornadoes are possible within the watch area in the coming hours.
Severe Thunderstorm Watches have been posted for a large area, stretching from eastern Illinois to upstate NY down into the mid-Atlantic. Strong, potentially damaging wind gusts are the primary concern for these locations.
The flash flood threat continues across several states as well with Flood Watches from DC to Philly to NYC.
Rounds of heavy rain and thunderstorms will continue to sweep across these regions through the afternoon and evening hours.
