Wet summer possible across much of Colorado
FRISCO — El Nino may bring above average rainfall to Colorado this summer, Grand Junction-based forecasters with the National Weather Service said in their latest update. The cyclical shift in Pacific Ocean sea surface temperatures affects the path of moisture moving off the Pacific and across the western U.S.

Based on computer model projections and comparisons with past years under similar emerging El Niño conditions, probabilities are tilted toward above-average precipitation for much of the summer, especially in late summer going into early autumn.
The biggest effects of El Niño are often felt during the winter months, but right now it’s unclear how strong this year’s El Niño will be or how long it will persist. Looking at the series of most recent El Niños, forecasters detect an overall trend of drier than average conditions, with periods of good snowfall scattered throughout the winter months.
Strong storms in late fall can put down a good base in the Colorado mountains, but El Niño winters are also often marked by long spells of dry weather in between stormy patterns.
