Air pressure changes affect the town’s weather. High pressure often brings clear skies and light winds. Low pressure can bring clouds, strong winds, rain, or snow. When moist air moves up from the plains toward the nearby mountains, it can produce heavier rain or snow around Lyons.
Lyons sits where the Great Plains meet the Rocky Mountain foothills. The mountains can block or lift moving air, causing more clouds and precipitation than areas farther east. They also help create sudden wind changes. Warm, dry winds flowing down the mountain slopes can raise temperatures quickly, especially in winter.
The local climate is generally dry, with more sunny days than cloudy ones. Temperatures can change quickly because of the town’s elevation and nearby mountains. Snowfall varies from year to year, while summer rain often comes in short, strong storms rather than long periods of steady rain.
