A warm and humid air mass will remain in place through Sunday, with partly to occasionally mostly cloudy skies and isolated thunderstorms on some days. A cold front is expected to move through on Monday, likely producing showers and thunderstorms across the region on Sunday and especially Monday, followed by a cool down for the mid-late week period with temperatures cooling down to near-below average.
Tuesday, August 27 Observations:
Behind Monday night’s heavy rainfall north of NYC, drier conditions and more sunshine returned for Tuesday along with a north wind, with a warm air mass aloft and continued humid conditions leading to warmer than average temperatures, peaking in the mid 80s to near 90 degrees for most except for eastern locations in the mid 70s to low 80s. The highest temperature was 90 degrees in Newark, and the coolest high temperature was 76 degrees in Montauk, NY.
