By sundown today, skies will cloud over and the temperature will drop to 21 degrees, noted weather forecasters.

By tomorrow afternoon, a blanket of snow will cover the area possibly as much as eight inches.

The National Weather Service said snow should move in by early moning and continue throughout the day.

The NWS is predicting four to eight inches locally.

Snow will continue until midnight when the snow will change to freezing rain and sleet, which is expected to continue through overnight hours.

A slight chance of snow is expected to fall on Saturday night into Sunday morning with new precipitation amounts to between a quarter and half-inch possible.

Sunday will be mostly cloudy, with a high near 34. North wind will be 8 to 14 mph, becoming west in the afternoon. Chance of precipitation on Sunday is 20 percent. Sunday night will continue to be partly cloudy with temperatures to drop to 12.

The impending snowstorm isn't taking people by surprise as it has been heavily forecast for much of the week.

According to AARP, drivers can keep themselves safe on the road in winter weather by following these driving tips:

Ÿ Take the time to winterize your vehicle to make sure your brakes, wipers, defroster, headlights and heater are all working properly.

Ÿ Stop your car gently to avoid skidding by pumping your brakes lightly. If your wheels start to lock up, ease off the brake.

Ÿ Be sure to turn on your headlights to increase your visibility to other motorists, and keep your lights clean and free of ice or debris.

Ÿ If you find yourself driving in unfavorable conditions, reduce your speed and increase the distance between your car and the one in front of you. Remember that it takes more time to stop on icy roads.

Ÿ Stay alert. Look ahead to give yourself more time to react safely to situations without suddenly braking or skidding.

Ÿ Before driving, clear snow and ice from your vehicle's hood, windows and roof.

Ÿ Use snow or all-season tires or chains for better traction and smoother slowing. But remember that regardless of the tires you use, no tire allows you to drive on snow or ice at normal speeds.

Ÿ Take extra precautions on bridges, overpasses and shaded areas, which can freeze first and remain icy longer than roadways. A road on which ice and snow are completely frozen is pretty slippery, even though it provides more traction than a road with melting ice.

Ÿ In wet driving conditions avoid driving faster than the windshield wipers can clear water from the windshield. Make sure your wiper blades are in good shape and replace them yearly.

Ÿ Equip your car with emergency supplies such as a blanket, food, water, spare fuses, a flashlight with batteries, an ice scraper, flares and a first-aid kit.
