Humidity levels will be climbing along with the mercury today, and heat advisories will be in effect for part of Alabama.

The National Weather Service is expecting air temperatures to climb into the mid- to upper 90s again on Thursday:

Those temperatures, combined with more moisture in the air, will make it feel even hotter, and the heat index could climb as high as 108 degrees in some areas.

The heat advisories have been issued for parts of north and central Alabama, while south Alabama has avoided them so far.

Here are the heat advisories for north Alabama:

Here are the heat advisories for central Alabama:

Several cities in Alabama cracked the 100-degree mark on Wednesday afternoon, though no records were broken.
