Snow and wintry precipitation continued to fall on parts of north Alabama on Monday morning, and it could spread southward and affect more of the state later today and tonight.

Winter storm warnings were in effect for north Alabama, which was expected to see the most wintry precipitation, and winter weather advisories will go into effect through the day in parts of central and even south Alabama.

Areas in north Alabama could get a total of 1 to 6 inches of snow, sleet and ice. Areas to the south may get less snow but enough ice to cause travel headaches.

The forecast for additional snow (not counting what has already fallen) is at the top of this post. Below is the forecast for ice:

The National Weather Service has gotten reports of accumulating snow in areas around north Alabama, and also reports of roads becoming icy and hazardous for travel.

Some of the higher snow reports so far are from Lauderdale County: 4 inches in Waterloo, 3.8 inches near Underwood, 3.75 in Cloverdale in and 2 inches in Florence.

More wintry precipitation was ongoing across parts of north Alabama early Monday:

Temperatures will be falling across the state today and will be especially cold tonight — which could cause icy spots on roads and make travel dangerous.

A hard freeze warning has been issued for north and parts of central Alabama tonight.

It will be even colder Tuesday night, with temperatures in the single digits and teens possible over a large part of Alabama. More hard freeze warnings and wind chill warnings will go into effect then for more of Alabama.

Here’s the low temperature forecast for tonight into Tuesday morning:
