After a brief spell of late-summer heat, a couple of rounds of thunderstorms will roll through the New York area, followed by some of the coolest weather of the season so far.
New York Central Park hit 90 degrees for the first time since Aug. 21 on Wednesday, but the clock is ticking on the hot, humid weather. Temperatures will peak close to 90 degrees on Thursday before storms come calling.
Storms will tend to be very spotty into Thursday midday. Most of the storms during this time will occur to the Appalachians to the north and west. However, storms Thursday afternoon and night will occur on a regional basis, reaching the I-95 corridor.

Any storm through Thursday can be locally strong with blinding downpours and gusty winds. A few areas could be hit with travel delays and sporadic power disruptions.

The storms will not break the hot and humid conditions until Thursday night.
With the humid air and spotty rain around Wednesday night, some areas may start foggy Thursday morning.
By Friday, Canadian air will settle in over the region with much lower temperatures and humidity, as well as a gusty breeze. Some people will feel refreshed, while others may mind the sudden chill. That breeze should prevent fog Friday morning.
The pattern Friday into the weekend could yield some of the lowest temperatures of the season so far for the metro area and the region in general. High temperatures may fail to reach 70 degrees in some locations.
Meanwhile, Gabrielle is forecast to remain well offshore of New Jersey, New York and New England waters this week, but affected Bermuda Wednesday with showers, gusty winds and rough seas.
Windswept rain from Gabrielle are forecast to spread from Nova Scotia to Newfoundland, Canada Friday into Saturday.
