The mild temperatures the Ann Arbor area experienced most of today are dropping slowly for the rest of the day, the National Weather Service says.

A high of 57 degrees Fahrenheit Thursday — just four degrees under the record high of 61 set in 1933 — is dropping during this breezy afternoon. A southwest wind of 10 to 20 mph was expected to change to a west wind of 15 to 25 mph, with gusts up to 30 mph.

Bryan Tilley, a meteorologist with National Weather Service in White Lake Township, says a cold front is moving through the area in place of the warm air that's been hovering the past couple days.

Friday will be mostly sunny with highs in the upper 30s. The December average is 36 degrees.

Looking ahead to the weekend forecast, Tilley said more average weather is expected: highs in the mid to upper 30s on Saturday and highs in the upper 30s Sunday. There may be occasional snowfall, too, with the chance around 40 percent. Tilley said there likely won't be any accumulation of note.

Meteorologists are currently tracking a weather system out west that may affect the Great Lakes early next week, although Tilley said they're still not sure of the track it will take. That system may bring a some notable snow showers on Monday and Tuesday.
