Strong NW winds on Friday have ushered in a cool autumn air mass, and the stage is set for our first widespread frost tonight and potentially even a hard freeze in some areas.
Winds will die down night, and under clear skies… temperatures in the upper 50s late Friday afternoon will quickly tumble through the 40s, and into the upper 30s after midnight. Data suggests widespread overnight lows between 32° and 37°. This will lead to frost developing, especially north of I-84. As you head into the traditionally colder spots, and the Catskills… low temperatures could briefly dip below freezing before dawn on Saturday. In those areas, a hard… season ending freeze is possible.
Accordingly, Frost advisories and Freeze warnings are in effect overnight. Freeze warnings are confined to Sullivan, Delaware, Western Ulster and Western Greene counties…. with the remainder of the region under frost advisories (Rockland & Westchester counties excluded). If you have sensitive plants, you may want to take precautions, as they could be damaged by tonight’s conditions.
A sign of the changing seasons. Have a nice evening!
