ST. LOUIS — A warmer start to the morning will lead to a slightly warmer afternoon as well. The lack of wind has really led to a lack of storm motion and the build up of ozone at the surface. As a result, the Orange air quality alert day is extended through Thursday. This will be a tough pattern to get out of for several more days. Children, active adults that spend a large amount of time outside, older adults and those with lung problems should limit time outdoors during the afternoon and evening hours.
With humidity levels a bit higher into Friday, slight chances for showers and storms will continue during the heat of the afternoon and early evening. While that low chance of rain continues through Friday, not everyone will be getting in on the rain. These showers and storms will be mostly heat and humidity driven, as they often are this time of year. Outside of a random downpour, rainfall will be nearly non-existent for the next week or more.
