A bit of snow and slippery spots will precede a cold weekend for the Ohio and Tennessee valleys.
The early stages of a developing storm along the Atlantic coast this weekend will tiptoe through part of the Midwest, interior South and central Appalachians Friday into Saturday in the form of spotty snow, snow showers and mixed snow and rain showers.
In most areas, the snow will not accumulate during the day Friday.
However, where the snow showers occur from Friday evening into Saturday morning, as colder air moves in and road surface temperatures cool, there can be a small slushy accumulation, especially on some bridges and overpasses.
The snow showers will occur in states from Arkansas to West Virginia, including the states of Tennessee and North Carolina.
Over the hilly areas from southeastern Kentucky and eastern Tennessee through the heart of the central and southern Appalachians Friday night into the first part of Saturday, there could be a couple of inches of snow, where the snow showers persist.
As Saturday progresses, the storm will begin to organize along the Atlantic Seaboard. The same storm could evolve into a blizzard over portions of Maine and neighboring Canada Saturday night into Sunday.
Snow showers are likely to continue over the central and southern Appalachians Saturday afternoon.
While the air coming in this weekend will not be the coldest of the winter around the Midwest, it will have a little bite with some wind adding to the chill.
Farther south, along the Gulf Coast to Florida, where skies become clear and winds diminish at night, temperatures could dip to their lowest levels of the season so far with the potential for a frost and freeze.
As the disabled cruise ship reaches the northern Gulf and passengers spend some time in the area, much colder air will be moving in.
