Will today be the hottest day of Alabama’s June heatwave?

It could for some spots, but the heat is forecast to hang on into the weekend, according to the National Weather Service.

Forecasters said Friday that plenty of warm and moist air will be available through the weekend for heat indices to be in the triple digits. Severe storms will also be a possibility both today and Saturday.

Parts of west Alabama will be under excessive heat warnings until Saturday night, and a large part of the rest of the state will be under heat advisories.

The air temperature forecast for today is at the top of this post. Below is the forecast for Saturday:

And here’s the Sunday forecast:

The heat index, or “feels like” temperature, could climb as high as 115 in the hottest parts of the state, according to the weather service.

Look for the heat to back off, at least some, by Monday, with more typical summertime temperatures expected next week.
