Most areas of New York and New Jersey are under their first frost warning of the season, effective Tuesday night through Wednesday morning. Meteorologists warn that temperatures will drop by 20 to 30 degrees.
If the mercury drops to 32 degrees or lower anywhere in the region, that would mark the first official freeze of the season.
After the warmest October in at least 119 years, upstate New York and the metropolitan region will experience the first freezing temperatures of fall during the first week of November.
The coldest air since April begins to leak in, bringing low temperatures of 30 degrees at night and even the possibility that there will be enough snow in some areas of the north of the state with lake effect to break the blades.
