Humidity values will remain intact so it will be muggy through the evening. EXTENDED: As we head into the middle of the week, the heat and humidity continue. High temperatures will reach the mid to upper 90s Wednesday with heat indices near 105 in the afternoon.

A few more storms could develop again late in the day Thursday but will become more likely Friday as the cold front moves south across all of Mid-Missouri. Temperatures will still be hot Thursday, depending on cloud cover from storms. Areas north of I-70 will stay in the low 90s but farther south, mid 90s will be reachable with heat indices at 100-104.
