Cool Start To Week: Mount Vernon's Work Week Weather

MOUNT VERNON, 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 in northern Westchester and points up the Hudson River.

"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."

Temps will be in the lower 40s before sunrise on Tuesday and Wednesday. If you've got sensitive plants still outside, cover them or consider bringing them in.

Here's what the National Weather Service says about the work week for southern Westchester:

• Today: Partly sunny, with a high near 60. Northwest wind around 17 mph.
• Tonight: Mostly clear, with a low around 40. Northwest wind 11 to 17 mph.
