A storm forecast to spread rain from the Mississippi Valley on Sunday to the Atlantic coast on Monday may end as a period of snow from parts of Ohio to parts of Massachusetts 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. The situation will be watched closely on a daily basis for the potential for localized severe weather from the lower Mississippi and Tennessee valleys to the Southeast 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 and may be close to the Interstate 80 corridor from Ohio to northern New Jersey.
The snow may extend as far south as I-70 in Ohio and western Pennsylvania and as far north as the New York Thruway.
In southern New England, this snow swath is likely to extend along portions of I-90 but could sneak to part of I-95.

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 at night or first thing in the 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.
This does not appear to be the type of storm that will bring down power lines, due to a generally light accumulation.
However, 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.
