Due in part to the moist and rich soils that make Iowa an agricultural powerhouse, summers are filled with very humid air. Coupled with heat, this can result in a very high heat index. This can make outdoor life very uncomfortable and sometimes dangerous for those unaccustomed to such conditions, even visitors from hot climates, such as the Southwest, where the heat lacks the coupling of humidity. In the winter, it is not at all unusual to have road closures due to snowfall or ice.
