- Weekend forecast calls for a return of mid- to upper 90s temperatures and high humidity.
Hot and muggy weather will tighten its grip on Kansas City on Wednesday, with heat index values expected to reach around 105 degrees, according to the National Weather Service.
Temperatures are expected to be slightly higher, climbing to around 96 degrees under sunny skies. The average temperature for this time of year in the metro is 89 degrees.
A heat advisory remains in effect until 7 p.m. for the metro and parts of east-central and northeast Kansas and north-central, northeast, northwest and west-central Missouri. The hot and muggy weather might cause heat illnesses, the weather service said.
“Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors,” the weather service advised.
Overnight temperatures will provide little relief from the heat.
Storms could bring torrential rains
A cold front is expected to move into the area overnight on Wednesday, bringing the threat of thunderstorms that are expected to be efficient rain producers. The heavy rainfall could lead to flash flooding, the weather service said.
The National Weather Service’s Weather Prediction Center has placed the metro and parts of northeastern Kansas and northern Missouri at a slight risk of excessive rainfall on Thursday and northern Missouri on Friday.
There is concern that the storms may move slowly or even stay over the same area for a while, the weather service said.
While severe weather is not expected with the storms, between 1 and 3 inches of rain is possible, with a few areas potentially seeing 3 to 6 inches, the weather service said.
With the ground already wet from previous rain, there’s a chance for flash flooding. A flood watch might be needed for Thursday and Friday, the weather service said.
The storms will bring a brief respite from the heat for some areas, with temperatures expected to climb into the low 90s on Thursday and Friday.
Hot, humid weather returns for weekend
The heat will again become a concern as hot and humid weather returns for the weekend, and is expected to continue into early next week, the weather service said.
Temperatures are expected to be in the mid-90s on Saturday, upper 90s on Sunday, and near 100 degrees on Monday. The last time Kansas City reached 100 degrees was on Aug. 25, 2023. Dew point values, a measure of humidity, will also be in the mid-70s.
Generally, during the summer months, dew points have to climb between 55 and 65 degrees before the weather feels sticky and muggy, according to the weather service. Dew points above 65 degrees make the heat oppressive and uncomfortable due to the high level of moisture in the air.
Heat index values could climb back in the 100 to 105 degree range, approaching heat advisory levels.
