:. Missouri Weather And Climate .:

Missouri Weather is determined by the competition between tropical airflows from the south and artic air flows from the north. Temperatures are higher when the tropical airflow is dominant and lower when the artic airflow is dominant. Storms, in the form of snow or rain, result when the two airflows collide. However, winters are normally dry and snowfalls are typically light.

Another characteristic of Missouri Weather is variability. Since there are no large bodies of water nearby and elevation isn't a factor, temperatures can vary by as much as 40° in a 24-hour period.

Tornadoes can be devastating, and Missouri averages 90 a year.
