Kansas City is starting Tuesday with clear skies and temperatures near 68 degrees, but the comfortable morning will give way to a warmer, more humid afternoon. The high is expected to reach 89 degrees, with the heat index climbing as high as 96. Winds should remain light from the east.

Afternoon Heat Builds Across Kansas City

Partly sunny skies will dominate much of Tuesday, and rain chances will stay near zero through the afternoon. Humidity will increase as temperatures rise, making the late-day heat feel more intense than the thermometer suggests. The National Weather Service says no watches, warnings or advisories are currently listed for the area.

Storm Chances Stay Limited

A slight chance of showers and thunderstorms arrives after 8 p.m. Tuesday, with a 20% chance of precipitation overnight. Wednesday brings another limited storm chance and a high near 89, but any rainfall should be light, with new amounts expected to stay below a tenth of an inch. Wednesday night should see temperatures fall.

Brief Cooldown Before Weekend Heat

Thursday offers the week’s nicest break from the heat, with sunny skies and a high near 86. Friday stays sunny and warms to about 88, giving outdoor plans a relatively comfortable window before temperatures climb again. Overnight lows will generally remain in the mid-60s to around 70.

Sunday Looks Hottest

Saturday is expected to reach the lower to mid-90s, followed by a mostly sunny Sunday with a high near 96 and a low around 78. The National Weather Service discussion says heat index values could approach or exceed 100 degrees Sunday afternoon as humidity returns. Hot and humid conditions are likely into early next week.
