Freezing fog a possibility in rural areas tonight. From OKX AFD:
Of particular concern is the potential for freezing fog tonight.
As the high shifts offshore, low level moisture will increase,
especially for western areas. With temperature dipping below
freezing, freezing fog is possible (more likely for the outlying
areas of non-metro northeast New Jersey and the Lower Hudson
Valley). However, there is still a fair amount of uncertainty
with the development of the fog, therefore, only went with
patchy freezing fog.
