Parts of Alabama woke up to snow, ice and very cold temperatures on Tuesday. And the National Weather Service is warning those in part of the state that the coldest temperatures in “decades” will be possible tonight and into Wednesday.

The snow and freezing rain was over for north and parts of central Alabama as of Tuesday morning, but freezing rain was still falling in parts of south Alabama, where winter weather advisories were still in effect.

Here is the forecast for additional ice accumulations through the morning:

The weather service warned Alabamians to only travel if necessary, keep devices charged, check on neighbors and bring pets indoors.

Highs today will not make it above freezing in a large part of the state, which will allow any frozen precipitation that has fallen to stick around into Wednesday.

Here are the forecast highs for Tuesday:

Then the coldest night of the winter is in store for all of Alabama tonight.

The weather service said morning lows in north Alabama are expected to fall into the single digits — or could even go below zero — and wind chills could make it feel like 5 to 15 degrees below zero.

Wind chill advisories and hard freeze warnings will be in effect for much of the state.

Another weather system is expected to move into Alabama Thursday night into Friday, bringing with it another chance of precipitation. As of Tuesday morning forecasters think the chances of additional accumulating wintry precipitation are low.

More dangerous cold temperatures are expected this weekend.

Here’s a look at what the National Weather Service is expecting statewide:

NORTH ALABAMA

The National Weather Service in Huntsville said north Alabama is facing dangerously cold temperatures and wind chills through Wednesday morning. Wind chill warnings and advisories are in effect for the region.

Low temperatures tonight could fall to the single digits or even below zero, and wind chills could make it feel anywhere from 5 to 15 degrees below zero.

The weather service also said temperatures could possibly get above freezing briefly on Wednesday before falling again, which could refreeze any liquid on surfaces on Wednesday night.

Forecasters are also looking at the weather on Thursday and Friday, when rain could arrive and transition to a wintry mix on Thursday night. Forecasters said the chances for snow or ice are low at the moment.

More extreme cold is anticipated this weekend.

Most locations north and west of I-85 will remain below freezing for the entire day, and bitterly cold temperatures are expected areawide tonight.
