Drier air and clearing skies are setting up another frosty Saturday morning across the Adirondacks.
A Frost Advisory covers parts of northern New York and Vermont, with temperatures forecast to drop as low as 32 degrees.
Where and When
The NWS Burlington office has the advisory in effect from 2 AM to 9 AM EDT Saturday.
In New York, it covers southeastern St. Lawrence, southern Franklin, western Clinton and western Essex counties. In Vermont, it’s Essex County.
Lake Placid, Saranac Lake, Tupper Lake, Star Lake, South Colton, Dannemora, Ellenburg, Newcomb, Lunenburg and Island Pond are all inside the advisory area.
Drier Air Sets the Stage
Forecasters were tracking this setup well before the advisory went up.
Drier air holds less heat than humid air, so once the wind shifts and skies clear out, overnight temperatures can fall fast, especially in low-lying valley terrain like the Adirondacks.
What Frost Can Do
Frost can harm sensitive outdoor vegetation. Plants left uncovered overnight may not survive until morning.
What to Do Tonight
Take steps now to protect tender plants from the cold.
Potted plants have it easiest: just move them indoors or into a garage for the night. Anything still in the ground needs a cover, a bedsheet, towel or frost cloth draped down to the soil traps enough ground heat to make a real difference.
Skip plastic sheeting directly on the leaves, though. It conducts cold rather than blocking it, and can do more harm than the frost itself.
Looking Ahead
Not everywhere in the region will see frost. Areas outside the advisory, including spots closer to Lake Champlain, should stay in the mid to upper 30s to mid 40s.
Saturday’s cold snap looks like a one-night event tied to this drier, clearer stretch, rather than the start of a longer pattern.
