Scorching temperatures and high humidity descend upon Kansas City. How hot will it get?

Dangerous heat and humidity is expected to build into the Kansas City area over the next few days, bringing the hottest weather conditions so far this year to the metro, the National Weather Service said.

A heat advisory has been issued for parts of the Kansas City area as hot and humid conditions are expected to send heat index values as high as 105 degrees for the rest of the week, according to the weather service.

The heat advisory begins at 1 p.m. Wednesday and continues until 7 p.m. Friday. Portions of east-central and northeast Kansas and central, north-central and west-central Missouri, which includes the Kansas City area, are under the advisory.

“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 said in the advisory. “Young children and pets should never be left unattended in vehicles under any circumstances.”

Those working or spending time outside should take extra precautions, possibly rescheduling strenuous activities to early morning or evening. Workers should schedule frequent rest breaks in shaded or air conditioned environments.

Temperatures are expected to be in the upper 90s on Wednesday and exceed 100 degrees on Thursday and Friday. Thursday will likely be the hottest day, according to the weather service. Muggy conditions will prevail across the metro, as dew points are expected to be near 70 degrees.

In general, when dew points reach between 55 and 65 degrees in the summertime, conditions become “sticky” or muggy. Dew points above that means there’s lots of moisture in the air and conditions are becoming more oppressive, according to the weather service. Dew points less than or equal to 55 degrees will make conditions feel dry and comfortable.

Overnight temperatures are expected to be in the mid- to upper 70s, which will provide some relief from the heat, according to the weather service. Temperatures need to drop to at least 80 degrees for people’s bodies to begin to recover from dangerous daytime temperatures.

A cold front is expected to move through on Friday. The timing of the front will determine how hot it gets on Friday. A few strong storms might be possible Friday night north of Interstate 70, according to the weather service.
