The heat will continue to crank up in Alabama on Saturday, and heat advisories will be in effect for a big chunk of the state.

The National Weather Service is forecasting air temperatures to climb into the 90s today in central and south Alabama, and that combined with high humidity levels will send the heat index — or “feels like” temperature — as high as 109.

Here is the air temperature forecast for Saturday:

There will be two heat advisories in effect for Alabama on Saturday:

*One heat advisory will be from 10 a.m. until 9 p.m. Saturday for Lamar, Fayette, Walker, Pickens, Tuscaloosa, Jefferson, Shelby, Sumter, Greene, Hale, Perry, Bibb, Chilton, Coosa, Tallapoosa, Chambers, Marengo, Dallas, Autauga, Lowndes, Elmore, Montgomery, Macon, Bullock, Lee, Russell, Pike and Barbour counties.

The weather service said heat index values up to 107 are expected in those areas this afternoon.

* Another heat advisory will be in effect from 11 a.m. until 7 p.m. Saturday for Choctaw, Washington, Clarke, Wilcox, Monroe, Conecuh, Butler, Crenshaw, Mobile and Baldwin counties.

The weather service said the heat index values of 105 to 109 are expected in those areas.

The heat isn’t going anywhere anytime soon. Look for highs to climb a little each day through midweek next week, when they could top out in the mid- to upper 90s, according to weather service forecasts.
