Folks along the I-81 corridor and beyond should prepare for the first big winter storm to hit in more than a year.
The National Weather Service in Baltimore offered the following forecast:
Snow before 4pm, then snow, possibly mixed with rain. The snow could be heavy at times. High near 34. Calm wind becoming southeast around 6 mph in the morning. Chance of precipitation is 100%.
Saturday Night
Rain and snow likely, possibly mixed with freezing rain before 1am, then a chance of rain and snow between 1am and 4am, then a chance of snow after 4am. Mostly cloudy, with a low around 28. Chance of precipitation is 70%.

Accuweather says how much snow falls will depend on the track of the storm and how much of a breeze off the mild Atlantic Ocean will develop.

“The odds favor a wintry mix that includes some rain, sleet and snow around the city from Saturday night to Sunday evening with mostly rain to the east and south. Where temperatures will be slightly lower to the north and west, the chances are higher for accumulating snow and dangerous ice.”

Local weather forecaster Will Astle of West Virginia Eastern Panhandle Weather said  although it was too early to nail down exact numbers, he predicts the snow will be “shovelable and sledable.”

Accuweather says there is the potential for significant travel delays to ramp up later Saturday with the worst conditions possible from Saturday night to Sunday.

1. Stay Informed: Stay abreast of local weather updates and advisories.
2. Emergency Kit Essentials: Assemble a supply of non-perishable food items, bottled water, flashlights, batteries, blankets, and a basic first aid kit. This preparation is paramount in the event of power outages or disruptions.
3. Home Preparations: Safeguard your residence by insulating pipes, allowing faucets to drip, and addressing drafts around windows and doors. Ensure your heating system is operating efficiently to maintain a warm and secure home environment.
4. Winter Supplies: Equip yourself with rock salt or ice melt for sidewalks, driveways, and steps. Have a snow shovel or snow blower on hand to facilitate safe mobility.
5. Car Check-Up: Prioritize vehicle maintenance by inspecting tires, brakes, and fluid levels. Maintain a filled gas tank and equip your vehicle with an emergency kit containing essentials such as blankets, a flashlight, and snacks.
