UPDATED by WeatherBug Meteorologists
One final disturbance in what has been a parade of weather disturbances will spread snow across the Midwest and into the Mid-Atlantic and southern New England this weekend. Lake-effect snow will also develop downwind of the Great Lakes this weekend.
A weak but fast moving low pressure system will move out of the northern Plains this morning and across the Ohio Valley this afternoon. With plenty of cold air in place and a sufficient supply of moisture, and fresh swath of snow will extend from the Plains this morning across the Ohio Valley this afternoon and into the Mid-Atlantic and southern New England later this evening into Sunday morning.
Snow accumulations will generally be in the 2 to 5 inch range this morning from eastern Montana into Iowa, with similar snow totals spreading eastward from Illinois to southwestern Pennsylvania and West Virginia this afternoon.
East of the Appalachian Mountains, snow will begin later this evening and will continue through the morning across northern Virginia to Massachusetts. A general 2 to 5 inches of snow is also expected Sunday morning, including cities such as Washington, Philadelphia, and New York City.
Winter Storm Warnings are in place across much of Montana, with Winter Weather Advisories in effect across South Dakota, central Iowa, central Illinois, central Indiana, central to northeastern Ohio, northern Kentucky, and western Pennsylvania. More Winter Storm Warnings have also been issued across portions of central Indiana, southern Ohio, West Virginia and southwestern Pennsylvania. Winter Weather Advisories also stretch from northern Virginia to southeastern New York.
As if that weren’t enough, an Arctic air mass will lead to a resurgence of lake effect snow this weekend across the Great Lakes. The lake-effect snow machine will keep chugging along the shores of the eastern Great Lakes. Snow accumulations of around 6 to 12 inches will blanket the primary snowbelts of northeastern Ohio, northwestern Pennsylvania, and southwestern and northern New York. Here, Lake Effect Snow Warnings and Winter Weather Advisories are in effect.
It’s never too early to have a supply kit packed in case of inclement weather. A simple kit including a weather radio, water, blankets, batteries, and non-perishable food items will go a long way in the event of a power outage. It’s always best to avoid travel in rough weather as the roads will be dangerous.
