There is some snow on the ground early this morning in parts of north Alabama.

But it's not much snow, and it won't stick around.

The National Weather Service in Huntsville early Sunday was watching a band of light wintry precipitation move across north Alabama.

Snow has been spotted in some areas:

Meanwhile, to the south, a cold rain was falling on parts of central Alabama.

Temperatures as of just after 3 a.m. Sunday had fallen to 32-34 degrees across much of north Alabama, the weather service said.

A winter weather advisory was in effect for DeKalb County in northeast Alabama until 7 a.m. Sunday. The advisory for Jackson County was cancelled as of 3 a.m. Sunday.

The weather service was still waiting on more snow reports to come in from observers as of early Sunday morning.

Forecasters had expected the higher elevations of Jackson and DeKalb counties to get up to an inch of snow.

Around a half inch of snow was possible north of the Tennessee River, and a light dusting was possible south of the river.

A few snowflakes could make it into north-central Alabama as well, according to the weather service in Birmingham.

The northernmost part of central Alabama has the best chance of seeing any winter weather, and the main window for the changeover will be just before or around sunrise on Sunday.

No accumulations are expected in central Alabama, forecasters said.

As of 3 a.m. Sunday a thinning band of wintry precipitation was moving through northern Alabama. It appeared the window for snow was over in much of north Alabama.

The weather service said the band moved in faster than anticipated and became more narrow as it progressed eastward. Drier air was filling in behind it.

Temperatures will fall near to below freezing overnight in north Alabama, but they won't stay there for long. Highs on Sunday will reach the 50s in much of Alabama.

More rain enters the forecast again by Monday, and a few snow flurries may be possible in northeast Alabama on Tuesday.

Much colder air will arrive after that disturbance departs, with low temperatures in the middle 20s possible across north Alabama and freezing temperatures possible southward into central Alabama.

The cold snap won't last: Highs will gradually warm up and by next weekend could be in the 60s again.
