Joplin's weather is affected by its location in the Midwest, where cold air from Canada meets warm air from the Gulf of Mexico, causing changing air pressure.
The city's geography, with the Ozark Mountains to the south and the Great Plains to the north, blocks or redirects air masses, making air pressure rise or fall.
In winter, cold air dominates, bringing low pressure and cold fronts with snow and freezing rain. In summer, warm air takes over, causing high pressure and hot, humid days.
