Huntsville heat wave forecast

1 3 — Triple-digit heat indices are expected over the next few days. (NWS)

The summer heat will be caused by whats known as a “heat dome,” or a strong upper-level ridge of high pressure across the Eastern United States. The high pressure will impact our weather here in Alabama.

The highest temperatures for the week are currently forecasted for Monday, June 29 through Wednesday, July 1 but the heat arrives this weekend. Here’s a look at some of the hottest forecasted temperatures for the week:

Anniston: 95 (Monday)
Auburn: 94 (Monday)
Birmingham: 97 (Tuesday)
Dothan: 94 (Sunday)
Florence: 97 (Wednesday)
Gulf Shores: 91 (Tuesday)
Huntsville: 97 (Wednesday)
Mobile: 94 (Monday)
Montgomery: 96 (Monday)
Tuscaloosa: 97 (Tuesday)

But as anyone in Alabama knows, it’s not just the high temperatures. It will also be the humidity, pushing that “feels like” temperature past the triple-digit mark.

Tips to stay safe in the heat

Until the weather starts cooling off, please make sure and take these precautions:

Slow down. Strenuous activities should be reduced, eliminated, or rescheduled to the coolest time of the day. Individuals at risk should stay in the coolest available place, not necessarily indoors.
Dress for summer. Lightweight, light-colored clothing reflects heat and sunlight, and helps your body maintain normal temperatures.
Limit foods (like proteins) that increase metabolic heat production and increase water loss.
Drink plenty of water or non-alcoholic fluids. Your body needs water to keep cool. Drink plenty of fluids even if you don’t feel thirsty.
Spend more time in air-conditioned places. Air conditioning in homes and other buildings markedly reduces danger from the heat. If you cannot afford an air conditioner, spending some time each day (during hot weather) in an air-conditioned environment affords some protection.
Don’t get too much sun. Sunburn makes the job of heat dissipation that much more difficult.

Reduce body temperature with cool cloths or bath. Use fan if heat index temperatures are below the high 90s. A fan can make you hotter at higher temperatures. Do NOT give fluids.
