Many have witnessed a more hazy sky over Missouri and the eastern two-thirds of the country due to wildfires in Canada and the Pacific Northwest.

This hazy sky has actually caused our daytime high temps to be cooler than expected by one to two degrees - less maximum solar radiation (sun's rays) reaching the ground.

By this weekend, we are expecting lesser concentrations of smoke and ash particulate in the atmosphere over Missouri which should lead to a slightly warmer temperature - highs in the lower to middle 90s this weekend.

Big heat and humidity expected for this weekend in Missouri and much of the Midwest. Heat advisories have been issued by the National Weather Service for northern Missouri and the St Louis area. Kansas City is under an excessive heat warning this weekend


Some patchy fog will be possible in the morning followed by a partly cloudy haze. Morning temperatures will be in the lower 70s with highs nearing 90 degrees. Heat Index values will be in the middle to upper 90s.

As heat and humidity return to the region, the heat index will be a major focus during the weekend and next week.

heat index trends

Heat indices will reach the middle to upper 90s Friday and will range from 100 to 105 this weekend and for much of next week. Please take steps to stay cool and hydrated over the next week to avoid heat exhaustion which can eventually lead to heat stroke.
