Temperatures are expected to dip into the mid to upper 20's in northern Westchester.
Skies will be clear with the windy conditions of the day calming down, creating favorable conditions for frost to form on vegetation and crops.
Sensitive flowers, vegetation and crops should be covered or, if possible, brought indoors as the frost could kill them, according to the National Weather Service.
Temperatures are forecast to return to the low 60's over the weekend.
