With daytime highs mostly in the 20s for the foreseeable future, it's safe to say our unseasonably warm weather is over, at least for now.

We'll need to wear a few extra layers through Friday, as frigid temperatures take over, according to the National Weather Service.

Sunday's high and low will both be a steady 26 degrees.

Monday, New Year's Eve, will be the "warmest" day of the week, with a high near 32 degrees, but wind gusts up to 20 miles per hour will make it feel colder. The low overnight Monday will drop to 17 degrees, with a 20 percent chance of snow.

Then, it's expected to really get cold. Here's a look at the rest of the week:

• Tuesday: First chance to see the sun, but the high is only expected to reach 20 degrees; overnight low around 11.
• Wednesday: Partly sunny, high of 23, overnight low of 15, slight chance of snow.
• Thursday: Partly sunny, high near 22, overnight low around 10, slight chance of snow.
• Friday: Mostly sunny, high near 21, overnight low around 14.
