A storm gathering moisture over the Southwest Monday has the potential to put down a swath of snow during the middle of the week from part of the Ohio Valley to part of the mid-Atlantic.
The storm is forecast to bring snow to portions of Oklahoma, northwestern Texas and southern Kansas Tuesday spreading to northern Arkansas and southern Missouri Tuesday evening according to Meteorologist Kristina Pydynowski.
The same storm will continue to move along an east to northeast path through the middle of the week.
Part of Kentucky and northern Tennessee are likely to have a mixture of snow and rain for a few hours Tuesday night. Where the precipitation comes down hard and switches over to all snow, there can be a couple of inches of accumulation. Rather mild conditions are in store during the day Tuesday for this area, but it will trend cold enough at night to allow snow to at least mix in at some locations.
Farther east, the storm system will push through part of the central Appalachians of West Virginia, Virginia and Maryland Wednesday. While wet snow is the favored form of precipitation in the mountains with up to a few inches possible, it could turn cold enough to allow a mix of snow and rain even in the valleys.
Marginal temperatures will continue to be an issue with rain versus snow for this storm as it pushes toward the upper coast of the mid-Atlantic later Wednesday and Wednesday night. The track of the system will also be crucial as to how much moisture is thrown into the northern mid-Atlantic.
The first part of the storm would be rain for areas from Washington, D.C., to Philadelphia and perhaps as far north as New York City, Long Island and southern New England. However, it is possible that just like over part of Kentucky earlier, that a change from rain to a period of wet snow takes place Wednesday night.
At any rate, it does not appear that the storm will bring widespread heavy snow from Kentucky to the mid-Atlantic, but pockets of a few inches of snow are indeed possible, where the rain switches over to wet snow quickly.
A storm tracking farther north in the East would mean a band of moderate to locally heavy snow would set up from the central Appalachians to southern New England, because such a storm would be somewhat stronger than a system passing by farther south.
AccuWeather.com meteorologists continue to monitor the potential for a larger storm during the weekend in much of the eastern half of the nation.
The atmosphere appears to be building a pipeline of storms for the next few weeks.
