Kansas City’s first shot of summer heat is coming. How hot will the weekend get?
AI-generated summary reviewed by our newsroom.
- Kansas City will see its first prolonged heat event of the season this weekend.
- Heat index values may reach up to 105°F Saturday due to high dew points.
- Relief expected early next week as dew points dip and storm chances rise.
A few lingering showers are expected in the Kansas City area Wednesday ahead of the metro’s first shot of extreme heat moves in for the weekend, according to the National Weather Service.
The better chance of lingering showers will be south of the immediate metro, across Linn County in Kansas, and in Bates, Henry, Pettis, and Cooper counties in Missouri, according to the weather service.
The primary weather concern will be the marginal risk of severe weather in the afternoon along a line from Harrisonville to Macon, Missouri.
“While the severe threat is expected to be low, there could be a few strong to marginal severe storms,” the weather service said.
The main threat will be gusty winds between 40 and 50 mph. The threat of stronger storms will quickly diminish as the sun sets early in the evening.
Temperatures are expected to be around 82 degrees in the metro, which is a few degrees shy of the typical 85 degrees for this time of year in Kansas City.
Heat index values to reach as high as 105 degrees in KC
The first blast of summer-time heat is not far away.
Temperatures on the Juneteenth holiday will be around 89 degrees. The weather is expected to be dry and sunny.
“The larger concern will be the expected longer duration heat in which high temperatures will reach into the 90s across the area, with 95-97F in far northwestern MO on Friday into Saturday,” the Weather Service said.
High dew point values in the low to mid-70s will accompany the heat on Friday and Saturday, allowing the heat index to climb to around 100 degrees on Friday and 105 degrees on Saturday.
“While even these heat indices may be marginal for heat advisory headlines as they must reach 105F for at least 2 hours, this will be the first heat event of longer duration of the season,” the weather service said in its forecast discussion.
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 due to a high level of moisture in the air.
Temperatures on Sunday are expected to be just as hot, climbing to around 93 degrees.
Overnight temperatures are expected to be in the upper 70s on Saturday and Sunday, which could hinder the body’s ability to recover from the hot weather during the day.
Bit of relief from heat expected early next week
Dew points are expected to drop into the mid-60s and lower 70s for Monday and Tuesday, providing some relief with lower heat index values. However, temperatures will remain in the lower 90s.
There will also be an increase in cloud cover, setting the stage for potential thunderstorms to move into the area on Monday. There’s a 20-30% chance of rain in far northwestern Missouri.
The best chance of thunderstorms will be along the Missouri-Iowa border on Tuesday, with a 20-35% chance of rain.
Temperatures are leaning above normal through the end of June, according to the National Weather Service’s Climate Prediction Center. The chance of rain is also leaning above normal for that period.
