While a winter weather advisory goes into effect at 6 a.m. for Jackson and DeKalb counties, some areas of north Alabama may be getting more snow than expected on Tuesday.

The National Weather Service forecast office in Huntsville raised the projected snowfall amounts to as much as 1 inch for north-central Alabama - including the city of Huntsville.

On Monday, those projections were for a half-inch of snow for all of north Alabama except the winter weather advisory areas.

While 1 to 2 inches is still expected Tuesday in Jackson and DeKalb counties, the weather service said the following counties may now receive a half-inch to 1 inch of snow: Madison, Marshall as well as the eastern half of Morgan, Cullman and a sliver of Limestone.

Essentially, points east of the I-65 corridor may get as much as 1 inch of snow while points west will likely receive less than a half-inch.

The weather service said that snow bands will likely make for inconsistent snowfall - meaning that some areas may only see some flurries while another location a few miles away may get a quick inch of accumulation.

The winter weather advisory for Jackson and DeKalb is set to expire at 6 p.m. No other north Alabama counties have been added to the advisory.

Whether it snows or not, it's going to be cold with temperatures expected to top out in the mid-30s Tuesday.
