Freezing rain possible for Blount County and northeast Alabama

The National Weather Service has issued a freezing rain advisory overnight for Blount County and all points to the northeast within Alabama,

Forecasters are saying that light rain will move into the area during the overnight hours. As that rain falls along a cold front, it will cool the atmosphere to freezing temperatures or below. Precipitation that falls as liquid will then freeze on contact with surfaces such as roads and vehicles.

The NWS says that the geographic line where rain stays as liquid and where it begins to freeze will be hard to pin down exactly due to the nature of the weather system, But for the moment the freezing line is forecast to be from Blountsville and Oneonta northward. However, minor shifts in the cold air could move it all the way to the Blount-Jefferson line, or could move it in the other direction out of Blount County altogether.

If freezing rain does occur, the weather service says that ice accumulations will be light, less than a tenth of an inch for Blount County. However, even a very thin coating of ice on roadway surfaces can wreak havoc with travel,

For now, Jefferson County is not affected by this advisory. Temperatures there are not expected to fall to 32 degrees or below.

There have been no preemptive closings of schools announced so far.
