York County residents may need umbrellas and jackets to get through the weekend.

Temperatures are expected to take a cool dip starting Saturday, with the high being in the upper 60s, according to the National Weather Service and Accuweather.com.

However, the temperature will lower to the mid-50s Saturday afternoon. Then the low temperature that night will be near 40 degrees, they said.

On Sunday, high temperatures will be around the low 50s. The night will be cooler with 40-degree temperatures, according to the National Weather Service.

The cool air is the result of a cold front moving down and eastward from central Canada, said Tony Mach, meteorological technician with the National Weather Service.

With the cold front comes the rain, said Brian Edwards, meteorologist with Accuweather.com.

There is a chance for showers during the days and evenings of Saturday and Sunday, Mach and Edwards said.

Sunday may be the wettest, as there's 70 percent chance for rain that day, Mach said.

Edwards gave a similar wet-Sunday prediction and said it will be a "very fall-like" day.

"We'll have chilly temperatures, periods of rain," he said. "It will be fairly cool out there. Not a nice day."

Even with the coolness and wetness, the county is still within the normal temperature range for this time of the year, Mach and Edwards said.
