Heat advisories remained in place for much of central and south Alabama on Friday, and some counties have been upgraded to an excessive heat warning.

The National Weather Service said the heat index, or “feels like” temperature, could reach as high as 112 degrees in parts of south-central Alabama this afternoon where the excessive heat warning is in effect.

The rest of south-central and south Alabama will also be under heat advisories through tonight.

Air temperatures are expected to top out in the mid- to upper 90s across those parts of the state this afternoon. That, combined with high humidity levels, will make it feel much hotter.

North Alabama is the only place not under heat advisories today, and that’s because of continued rain and storms that are helping to keep temperatures more in check.

But there could be some stronger storms later today, and parts of the state will have a Level 2 risk for severe weather later this afternoon and into the overnight hours as a frontal boundary sinks southward across Alabama.

Heat levels are expected to back off some more for areas north of the front on Saturday, but temperatures will continue to be very hot for those south of the front in south Alabama.

Here is the forecast for Saturday:
