Not only is it hot, it also is humid this week. The heat index, which is a “feels like” temperature, looks at how hot and humid it is outside. When the air is moist and it is hot, our bodies can overheat because it is harder for sweat to evaporate (this evaporation helps cool our bodies). The heat index for the first half of the week will likely stick to the middle to upper 90s.
