Flood advisories have been the main topic of weather discussion in Alabama for the past few weeks, but this week some of the rain gives way to extreme heat.

Unless you suffer from agoraphobia and haven't left the house in a few days, you've noticed the extreme heat in Tuscaloosa. Warm temperatures along with high humidity have lead to heat indices approaching or exceeding 105 degrees over much of Central Alabama since Monday and it isn't letting up.

The National Weather Service in Birmingham has issued a heat advisory for most of Alabama. The advisory reads,

...HEAT ADVISORY NOW IN EFFECT UNTIL 7 PM CDT WEDNESDAY...

* WHAT...Heat index values 104 to 108 each afternoon.

* WHERE...Portions of west and south central Alabama.

* WHEN...Until 7 PM CDT Wednesday.

* IMPACTS...Hot temperatures and high humidity may cause heat illnesses to occur.
