Snow Across the Midwest and East, Icy in the South
January 18, 2024
By WeatherBug Meteorologist, Rob Miller
More wintry troubles are expected today and Friday for areas of the Midwest into Tennessee Valley, while wintry troubles move through the East on Friday.
A fast moving upper-air disturbance will bring a swath of snow across the Plains this morning and across the Midwest and Ohio Valley into Friday morning. The snow is expected to be the light, powdery type, with a general one to three inches expected from Iowa and northern Missouri eastward through southern Michigan, Ohio, western Pennsylvania, and into the Central Appalachians.
Farther south, as slightly milder air interacts with the disturbance, leading to snow and freezing rain will fall across portions of the Lower Mississippi Valley into the Tennessee Valley and southern Appalachian Mountains. While snow amounts are expected to be under 1 inch in most areas, a glaze to 0.05 inches of icing will be possible today, resulting in dangerous travel conditions.
Winter Weather Advisories have been issued across portions of southwest North Dakota, much of South Dakota, northeastern Nebraska, much of Iowa, northern and central Illinois, northern and central Indiana, and into northwestern Ohio. Another swath of advisories extends across eastern Arkansas, southeast Missouri, Tennessee, northern Mississippi, northern Alabama, northeastern Georgia, much of Kentucky, southern Illinois, Ohio, western Pennsylvania, western Virgnia, and into the southern Appalachian Mountains. There are even some Winter Storm Warnings scattered about through the central Appalachians, downwind from Lake Erie and Lake Michigan, and around the Philadelphia metropolitan area.
As this disturbance continues to move eastward later tonight and Friday, snow will spread across portions of the Mid-Atlantic states into southern New England. A general one to three inches of snow will be possible by Friday evening, including around Washington, Philadelphia, and New York City.
Winter Weather Advisories have also been issued across southern and eastern Pennsylvania, Delaware, Maryland, northern Virginia, and New Jersey for this portion of the event.
Following this disturbance, lake-effect snow showers will persist into the weekend where several inches of additional snow accumulation is expected.
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.
