Weather models have shifted the moisture further to the South than forecast on Sunday. As a result, the National Weather Service in Huntsville has adjusted their forecast this morning.
They have issued a Winter Weather Advisory for snow, which is in effect from 6 PM this evening to noon Tuesday. The Winter Storm Watch is no longer in effect.
Snow will develop as early as this evening, but will become more widespread after midnight.
The greatest chance of snowfall in north Alabama is expected south of the Tennessee River. Snowfall accumulations of 1 to 2 inches are possible.
For areas north of the Tennessee River, expect a half inch to 1 inch of snow, with less nearer the Tennessee border.
There remains significant uncertainty with this weather system, including the various precipitation types that could occur.
While snow and sleet appear to be the main weather hazards for North Alabama, freezing rain could also become a hazard if the track of the system varies.
More wintry weather is expected across the area Tuesday night into Wednesday as a stronger system impacts the area. 1-3 inches of snow is possible in Northeastern Alabama, with lesser amounts of 1/2 to 1 inch possible over Northwest Alabama.
