Kansas City and the surrounding region faced dangerous early-summer heat in late June and early July, with many area locations reporting heat-index values of 105 degrees or greater.

Regional reporting on July 1 described the conditions as a dangerous heat wave. The heat index, which reflects how hot conditions feel when humidity is considered alongside air temperature, reached or approached the 105-degree threshold at many locations in the Kansas City area.

Forecasts warned of continued hazardous heat i

Before the peak of the event, reporting on June 29 said extreme-heat warnings covered Kansas City and west-central Missouri. Forecast heat-index values were projected in a range of about 105 to 110 degrees.

National Weather Service forecasts cited in local reporting indicated that dangerous heat could continue through the July 4 weekend, with limited chances for storms. Those projections described expected conditions for the broader region; they should not be read as citywide observations for Kansas City, Missouri.

The available reporting does not establish a temperature record, nor does it document a specific number of heat-related illnesses, deaths, power outages or water-system failures tied to the heat wave.

Potential pressure on public systems i

The heat was reported as having the potential to affect transportation, electrical and water systems. That was a possible consequence of the extreme conditions, not a finding that those systems failed during the event.

For people spending time outdoors during the high-activity summer period, the event underscored the importance of hydration, access to cooling and other heat-safety measures. The documented hazard was especially significant because forecasts kept the possibility of dangerous heat in place into the holiday weekend.

Later forecast is separate from the heat-wave reports i

A National Weather Service Kansas City/Pleasant Hill point forecast cited in the source packet covered Kansas City, Missouri, through Aug. 3 and included recurring chances of showers and thunderstorms during its forecast period. That later forecast is separate from the late-June and early-July heat-wave reporting and does not establish that an extreme-heat warning was active on Aug. 3.

The National Weather Service is the relevant local forecasting authority for the area. The supplied materials do not include the issuance time or a specific expiration time for the late-June extreme-heat warnings; they do establish that forecasts described dangerous heat through the July 4 period.
