May weather forecast
Colorado, USA

May ushers in a definitive spring feel across Colorado, with a substantial warming trend and an increase in rain rather than snow in the lower regions. In the Eastern Plains, temperatures typically range from 40°F (4.4°C) to 60°F (15.6°C), creating a comfortable and pleasant climate.

Cities like Boulder, nestled in the Front Range urban corridor, enjoy the emergence of green landscapes, blooming flowers, and more consistent spring weather. Yet, the higher elevations, particularly in the Rocky Mountains, might still experience snowfall, allowing ski resorts to operate into late spring.

Precipitation in May shifts predominantly to rain in the plains and lower elevations, nurturing the growth of vegetation. Thunderstorms may begin to occur, a characteristic weather pattern that continues into the summer months.

May represents a noticeable departure from the colder months, leaving behind the significant snowfall and frigid temperatures of winter. Even though the mountainous regions can still exhibit wintry conditions, the majority of the state enjoys the warmth and renewal that define the spring season. The transition from April's more erratic weather to May's steadier temperatures highlights the evolution towards summer in Colorado.
