St. Louis, Mo. – Missouri residents can expect a mostly dry and cooler-than-normal Labor Day weekend, with the most comfortable weather arriving on Monday. Temperatures will ease down each day, starting in the mid-80s Saturday and dipping into the mid-70s to near 80 by the holiday.
According to the National Weather Service in St. Louis, skies will stay partly sunny Saturday before clouds gradually increase Sunday. By Labor Day, central Missouri could see a 20–30% chance of showers, though most of the state will remain dry. The weekend trend favors cooler afternoons, making outdoor gatherings more comfortable compared with recent late-summer heat.
Travelers heading across I-70 or into central counties such as Boone and Cole should prepare for more cloud cover and the possibility of light, passing rain showers Monday afternoon. However, no widespread storms or hazardous weather are expected.
Residents planning cookouts or outdoor events will likely find Saturday and Sunday the driest windows, with Labor Day Monday leaning cloudier and cooler.
Temperatures are expected to stay below seasonal norms through early next week, and no significant rainfall or heat is on the horizon.
