A storm forecast to spread rain from the Mississippi Valley on Sunday to the Atlantic coast on Monday may bring a brief period of snow to parts of the Great Lakes and interior Northeast early next week.

A storm will progress eastward across the central and eastern United States this weekend to next week. For the most part, the storm will produce wet road conditions. However, motorists over the northern edge of the storm may have to contend with snowy travel.

While far from a blockbuster storm, the feature will bring some rain to areas that experienced flooding in recent days and weeks over the Central states.

Not enough rain is expected to fall to aggravate river flooding, even though some rivers such as the lower Missouri and middle Mississippi will rise from prior snowmelt and rainfall.

Locally heavy thunderstorms will accompany the storm as it progresses eastward into the lower Mississippi and Tennessee valleys and Southeastern states.

While rain is expected to be the only form of precipitation over the Ohio Valley and much of the mid-Atlantic states, just enough cold air may seep into the tail end of the storm near the northern edge to bring a period of snow.

How much cold air presses in will determine how quickly the changeover takes place, how long it lasts, how much snow will fall and how far north or south that band of snow extends.

At this time, the swath of snow is expected to be mainly light and on the order of a coating to a few inches from portions of New York state and New England to perhaps the Interstate 80 corridor of Ohio, Pennsylvania and northern New Jersey.

The timing of the storm may impact how much snow accumulates on the roads. Where light snow falls during the midday or afternoon, roads may be just wet. Where the snow falls on Sunday night or first thing Monday morning, roads may be slushy and slippery.

Snow may accumulate at any time over the higher elevations, bridges and overpasses and in areas that do not receive direct sunlight during the day. Any accumulation will not last long, as sunnier, milder weather builds through midweek.

The storm will follow a major storm that brought everything from flooding rain to heavy snow and high winds into the first weekend of March.
