Kansas City is waking up Saturday, but temperatures will rise through the day. Temperatures will climb into the upper 80s to mid-90s by afternoon, setting the stage for several days of near-100-degree heat across the metro.

Saturday Starts The Heat Buildup

Saturday's Kansas City aviation forecast called for scattered to broken clouds, not an explicitly mostly sunny sky, with southerly winds initially at 7 to 12 knots, increasing to near 15 knots, with gusts of 20 to 25 knots. The forecast identified a 15% to 25% chance of showers or thunderstorms across northern Missouri overnight into Sunday morning, according to the National Weather Service.

Saturday night will remain warm and breezy, though the overnight forecast does not specify a sky condition, low temperature or evening heat-index value.

Sunday Through Wednesday Stay Near 100

Sunday's forecast calls for temperatures in the mid-90s to near 100 degrees, with heat-index values from 95 to 104 degrees. Monday's forecast calls for mid-90s to near 100, followed by mid-90s to near 100 Tuesday and Wednesday.

Kansas City has also experienced periods of heat.

The forecast included 15% to 25% precipitation chances in northern Missouri overnight into Sunday morning, plus another 15% to 25% chance Wednesday night into Thursday. The forecast indicated 15% to 25% shower and thunderstorm chances extending into Thursday night and Friday, with temperatures described as mid- to upper-90s rather than exact highs of 97 degrees Thursday and 95 degrees Friday.

Plan Around The Afternoon Heat

No watches, warnings or advisories are posted for Missouri or Kansas in the current forecast, but the prolonged heat still calls for basic precautions. Outdoor work and exercise will be safer earlier or later in the day, while anyone spending time outside should drink water, take breaks in shade or air conditioning, and check on older neighbors, children and pets.

Extreme heat combined with high humidity can harm human health.

With temperatures hovering near 100 for much of the week, a parked car can become dangerous quickly. Never leave people or animals inside a vehicle, even for a short errand.
