Forecasters are predicting a mixture of rain, snow and sleet across parts of northern Alabama Tuesday before the precipitation changes to all snow late Tuesday night.
The National Weather Service predicts less than a half-inch of new snow and sleet accumulation in cities such as Huntsville and Florence. Higher amounts will be possible at higher elevations of northeast Alabama, such as areas near Lookout Mountain.
Forecasters say that some icy and slick spots on roads will develop, especially on bridges, overpasses and less-traveled secondary roads.
A spokesman says Alabama state troopers were caught off guard by last week's snow, which caused an overnight traffic jam on Interstate 65.
Trooper spokesman Curtis Summerville says road conditions worsened faster than officials expected once the snow began coming down.
Summerville tells The Decatur Daily (http://bit.ly/1416Bez ) authorities are looking at ways to do things better in case of a repeat. He says possibilities include using billboard or twitter to inform motorists of blocked roads.
