By this afternoon, highs will climb into the upper 90s under a partly to mostly sunny sky. When humidity is factored in, it will feel like 105 degrees or higher. This is why heat alerts are in effect to start the week. A rogue shower could develop, but most areas will remain dry, hot, and humid.

Severe storms become possible Monday evening into Monday night as cooler air gradually settles into Siouxland over the next several days.
