As clouds exited the region last night, a high pressure will build in today through Thursday, resulting in temperatures warming back up to above average with highs in the mid 80s to near 90 degrees. A cold front will move through on Thursday night, bringing cooler temperatures for Friday and the weekend, followed by a more active pattern towards next week with higher temperatures and an increased risk of rain/thunderstorms (Image credit: PSU e-Wall).
Monday, August 19 Observations:
A weak wave of low pressure exited the area early on Sunday after producing scattered showers, although mainly cloudy skies persisted across the area on Monday, which was more than expected, resulting in cooler high temperatures than forecast. Highs reached the upper 70s across most of the area, with low 80s in northern parts of the area and most of Long Island. The highest temperature was 81 degrees in multiple locations, and the coolest high temperature was 76 degrees in Yorktown Heights, NY.
