The weather on Saturday was an extremely rare combination of heat, humidity, and strong winds. Typically, those three don't happen simultaneously as strong winds are more limited during the hottest time of the year and strong winds tend to promote lower atmosphere mixing, which lowers afternoon humidity levels as drier air aloft is mixed down to the surface. For some on Friday and now much of the Midwest on Saturday, the combination of high temperatures, high humidity, and strong winds occupied a parameter space unobserved for many of the major airport weather stations. The featured table presents an unofficial IEM accounting of observations without any comparables. This means that no other observation for the site on record had at least the same temperature, dew point, and wind speed combination shown in the table. To clarify, there have certainly been observations with higher temperatures, dew points, and wind speeds, but none occurring simultaneously. Sunday will be a near repeat of Saturday, so will update the table if new extremes are set tomorrow!
