First taste of dangerous summer heat descends upon Kansas City

It’s about to get hot, Kansas City — dangerously hot.

The rains have kept the early season heat away. But now that the rains have moved out, the heat is headed in. And come Saturday, Kansas City will see its first dangerous temperatures of the season, according to the National Weather Service.

Friday appears as if it will be the coolest day for the next several days. Highs are expected to be in the upper 70s to middle 80s.

“Main story heading into the weekend will be the arrival of the heat monster as a plume of very warm air aloft begins to move over the area by Saturday,” the National Weather Service said in its area forecast discussion report.

The five-county Kansas City metropolitan area will be under a heat advisory from noon until 9 p.m. Saturday.

The National Weather Service is warning that Saturday afternoon temperatures will range from the lower to middle 90s. But because of the humidity, the heat index values will hover around 105 degrees.

The heat and high humidity could result in heat-related illnesses. Also, vehicle interiors can reach lethal temperatures in minutes, so people should not leave children or pets in unattended vehicles.

The National Weather Service is advising those who work outside to take frequent breaks in shaded or air-conditioned areas.

Also late Saturday afternoon through the evening, there is a chance for severe weather north of a line from St. Joseph to Macon, Mo. Large hail and damaging winds are the primary threats.

Warm, muggy conditions are likely to hang around into next week as highs are expected to top out in the 90s every day through Wednesday. The heat index values are expected to be near 100 degrees each day.
