Dropping temperatures and the threat for snow showers into the weekend begins Tuesday afternoon.

The National Weather Service has issued a Winter Weather Advisory, which goes into effect at 4 p.m. Tuesday and carries through Wednesday at 12 p.m.

The advisory covers Summit and Portage counties.

The warm, moist air from the Gulf will move out of the Akron-area region by the afternoon on Tuesday. Cooler temperatures are expected into the evening.

"As we head through the evening, we'll see that one to three, maybe four inches of snow accumulated," Tony Jackson said, Weather Channel meteorologist.

After this low pressure system moves out overnight, a new system will move in and could bring lake-effect snow showers through the weekend.
