Autumnlike Cool Will Change to Summery Heat From Kansas City to Minneapolis

The heat that has been building up over the central Plains will push eastward into the Midwest late this week and early this weekend.

This will be a big change from the bout of cool weather the region experienced earlier in the week, when highs were mainly in the 60s and 70s. Forecast high temperatures in many locations will be 10 to 20 degrees higher compared to this past Monday and Tuesday.

Humidity will be higher as well, making it feel even warmer.

High temperatures in Omaha, Neb., will be in the middle 90s Friday and upper 90s Saturday. AccuWeather RealFeel temperatures, which factors in other parameters such as humidity and wind, will peak around 102 degrees Saturday afternoon. The average high in Omaha this time of year is in the lower 80s.

The high temperature this past Monday in Minneapolis failed to reach 70 degrees. Highs late this week and early this weekend will be around 90 degrees. This will be well above normal for early September, with the average high in the middle 70s. RealFeel temperatures will be in the lower 90s.

It will be a similar story for places like Des Moines and Kansas City.

Temperatures Friday and Saturday in Des Moines will soar into the low to middle 90s with RealFeel temperatures in the middle to upper 90s.

Highs Saturday and Sunday in Kansas City will challenge the record of 97 and 98, set in 1978 and 1983 respectively. RealFeel readings will around 100 degrees over the weekend.

While the Kansas City Chiefs will open their NFL season on the road Sunday, it will take them to the heat and humidity of Jacksonville, Fla., to take on the Jaguars. Temperatures will be near 90 degrees at kickoff with RealFeel temperatures in the middle 90s.

The early week cooldown was a break from the intense heat wave that gripped the Plains and Midwest last week. This provided an opportunity for people to open the windows and give air conditioners a rest.

Last Friday, the thermometer in Des Moines soared to 104 degrees, establishing a new record for the date. Temperatures were at or above 90 degrees each of the last nine days of August.

Air conditioners will be back on full blast late this week and into the weekend. This will certainly contribute to a higher electric bill for many people.

If you will be working outside in this heat, it is important to take frequent breaks. Drinking plenty of water is of utmost importance to avoid becoming dehydrated.

The NFL season kicks off Thursday evening in Denver, Colo., with the Baltimore Ravens making a return to the Mile High City.

Temperatures at kickoff will be in the middle 80s under partly cloudy skies. Dry weather is expected throughout the contest

During last season's playoffs, the Ravens and Broncos met in Denver on a bitterly cold day in January.

It was the coldest postseason game in Broncos' history with a kickoff temperature of 13 degrees according to National Weather Service Meteorologist Jim Kalina.
