Hartselle City and Morgan County schools will be closed Friday due to the threat of snow and ice all day Friday.

A winter weather advisory has been issued for Morgan County Friday from 6 a.m. to midnight.

The National Weather Service is forecasting ice and snow to bring hazardous conditions to southern middle Tennessee and northern Alabama from Friday morning until Saturday morning.

“A developing storm system will quickly spread moisture into the area by early Friday morning,” the weather service said in an advisory. “With abundant cold air in place, it is expected that the precipitation will begin as a period of snow.”

As warm air moves northeast into the area, the snow is expected to transition to a sleet and freezing rain mixture by Friday afternoon and continue into Friday night.

Northeast Alabama and southern middle Tennessee may have a longer duration of sleet and freezing rain from Friday afternoon until Saturday morning.

Ice amounts around a tenth of an inch are expected along and south of a line from Florence to Cullman. Ice amounts greater than a quarter of an inch are expected along and north of a line from Huntsville to Fort Payne Alabama extending northward into southern middle Tennessee.

Accumulations are forecasted to be up to a half an inch of snow and sleet and a tenth to less than a quarter an inch of ice.
