What is the weather like year-round?

Missouri experiences a humid continental climate with four distinct seasons, characterized by hot summers, cold winters, and moderate spring and fall. The weather varies across the state due to its central location in the U.S., with northern areas generally cooler and southern areas warmer. Summers can be hot and humid, especially in cities like St. Louis and Kansas City, with average highs often reaching the upper 80s to low 90s Fahrenheit (30-35°C). Winters tend to be cold, with average lows in the 20s Fahrenheit (-6 to -1°C), and occasional snowfall, particularly in northern Missouri.
