Frost Advisory Issued: Yorktown's Weather

SOMERS, NY — After a weekend in the 70s, temps in the Hudson Valley are swinging the other way. It's due to a cold air mass blowing in from Canada. And the air is cold enough to bring a Frost Advisory for early Tuesday to northern Westchester.

"October has been a very warm month in the Hudson Valley. Temps half way through the month are a full 8 degrees above average," said Bill Potter of Hudson Valley Weather. "So Monday will feel drastically different, as we see some major changes."

The National Weather Service posted:

• Frost Advisory in effect from October 17, 02:00 AM EDT until October 17, 09:00 AM EDT
• Hazardous Weather Outlook

Temps will be in the lower to mid 30s before sunrise on Tuesday and Wednesday. If you've got sensitive plants still outside, cover them or bring them in.
