About Great Falls weather

Great Falls is in Cascade County, Montana, United States at 47.50°, -111.30°. Right now it’s 47° and clear; today’s high is 78° with a 0% chance of rain.

Montana's climate is defined by its position as a gateway between the Pacific maritime influences from the west and the harsh continental climate of the northern Great Plains. The state holds the record for the largest 24-hour temperature change in U.S. history, when Loma experienced a 103-degree rise from minus 54 to 49 degrees Fahrenheit in January 1972. The Continental Divide runs through the western mountains, creating dramatically different weather on either side.
