Fort Collins has already received 3.64 inches of precipitation in May, exceeding its monthly average by nearly an inch. This surprising early signal for Colorado's monsoon season offers a deceptive sense of relief. The city's May precipitation is almost an inch above its 2.72-inch monthly average, according to The Coloradoan.
However, much of Colorado remains in moderate to severe drought, even as the state is forecast for a wetter-than-normal summer. Fort Collins and much of Larimer County are in moderate drought, while far western areas face severe drought, according to the University of Nebraska drought monitor map released May 21, as reported by The Coloradoan. This localized rainfall creates a dangerous illusion of recovery, masking persistent and severe drought conditions across much of the state.
While this summer's rainfall may offer some immediate relief to parched landscapes and reservoir levels, it is unlikely to fully reverse the effects of decades of drying trends and will require continued vigilance regarding water conservation.
A Wetter Summer Ahead?
Colorado is expected to experience a wetter-than-normal summer with an active monsoon season and developing El Niño conditions, according to The Post Independent. This marks a substantial departure from recent dry summers, offering a potential short-term boost to the state's water resources.
Contrasting with Long-Term Drying
Northwest Colorado summer precipitation has decreased 20% since the 1951-2000 period, according to climate data. This drying trend exacerbates the long-term aridification challenging the state's water security. While a wetter summer, driven by El Niño and an active monsoon, offers a temporary reprieve, it will not reverse the decades-long 20-22% precipitation declines in critical regions of Colorado, as evidenced by climate data.
Regional Hotspots for Heavy Rain
Southwest Colorado spring precipitation has decreased 22% since the 1951-2000 period, according to climate data. This region, alongside southeast Utah, holds the best potential for heavy rain, according to Weather. The historical drying in Southwest Colorado makes this forecast particularly critical for drought relief, though effective water capture remains a significant challenge.
Immediate Forecast: Showers and Variability
An increase in showers and thunderstorms is expected Sunday, according to Weather. This marks the beginning of a wetter pattern for parts of the state. Colorado's water managers face a complex challenge: short-term deluges followed by dry spells will make it harder to capture and store water effectively, exacerbating long-term supply issues.
Will the Wetness Last?
What is the typical start date for the Colorado monsoon season?
Colorado's monsoon season typically commences in early July, bringing increased humidity and daily thunderstorm chances. This seasonal shift is a crucial component of the state's annual precipitation cycle, though its intensity varies year to year.
How does El Niño affect Colorado's weather patterns?
El Niño conditions generally lead to a warmer and drier winter for northern Colorado. However, they can contribute to increased moisture during summer months, especially when combined with an active monsoon. This pattern results from altered jet stream configurations that influence storm tracks.
Will 2026 be a wet year for Colorado?
Despite forecasts for a wetter summer, periods of variability are expected. Drier air is expected to move back into the region Sunday evening and remain through next week, according to Weather. Continuous rainfall is unlikely even in a generally wet season, demanding ongoing monitoring by water resource managers.
