About Saint Charles weather
Saint Charles is in Saint Charles County, Missouri, United States at 38.78°, -90.48°. Right now it’s 60° and clear; today’s high is 89° with a 1% chance of rain.
Missouri has a humid continental climate in the north and a humid subtropical climate in the south, placing it at the convergence of multiple weather influences. The state's central location means it receives weather from every direction — Arctic cold from Canada, Gulf moisture from the south, and dry air from the west. This produces highly variable weather and the common saying among Missourians to wait five minutes if you don't like the weather.
