Temperatures across Alabama are expected to be above average — for even mid-June — over the next few days.

The National Weather Service is warning Alabamians to take precautions this weekend, because it’s early for this kind of mid-August heat in the state.

Temperatures on Friday were expected to rise into the 90s statewide, and some places in south Alabama will see the upper 90s (see today’s forecast at the top of this post).

Saturday and Sunday could be even hotter, with several areas expected to come near to or break the triple-digit mark.

Here is the forecast for Saturday:

And here’s the Father’s Day forecast (Sunday):

The National Weather Service cautioned that many may not be acclimated to this kind of heat so soon in the summer.

Combining the expected temperatures, the time of year, overnight lows and CDC research results in what the weather service said was an elevated risk for heat illnesses or other related effects this weekend in parts of Alabama.

NOAA is expanding the use of an experimental heat risk gauge — called HeatRisk — that aims to provide guidance for those who are particularly vulnerable and may need to take extra precautions in extreme heat.

Here’s the heat risk map for today:

* Areas in yellow, or Level 1, have a minor risk for heat-related impacts.

* Areas in orange, or Level 2, have a moderate risk.

* Areas in red, or Level 3, have a high risk.

There is also a Level 4, or extreme risk, which signals a period of rare or long-duration extreme heat with little or no relief overnight.

The heat risk forecast for Saturday shows an expansion of Level 3 risk in Alabama:

The heat risk forecast for Sunday shows some parts of Alabama reaching that Level 4, or extreme risk, partly because it’ll be the third day of above-average heat:

The weather service said that while the heat index (or “feels like” temperature) won’t be at extreme levels, “that only tells part of the story … this heat wave being early in the season and persisting for several days could lead to higher heat-related impacts than we typically see at these same heat index values.”

The weather service is forecasting heat levels to come down some by Monday, when highs are expected to be in the low 90s for much of the state:

Unfortunately there are no signs of a cool snap in the immediate future. NOAA’s Climate Prediction Center is forecasting an increased probability of above-average temperatures for Alabama through the rest of the month and into July.
