I thought this article from the Denver Post was interesting. I think the last El Nino had incredible March snow falls and water levels were really high in the Spring. Hopefully that will happen again. As the article says, don't get discouraged if December-January snow is light.
Scientists are predicting that Colorado's late-fall snowstorms could disappear by mid-December as a result of El Niño, which occurs when Pacific Ocean surface temperatures are warmer than normal.
El Niño is gaining strength, said Klaus Wolter, a scientist at the University of Colorado at Boulder and the National Oceanic and Atmospheric Administration.
Consequently, dry midwinter conditions will probably develop for Colorado and then disappear by late February or early March.
"March has a tendency to produce copious snow amounts with El Niño," Wolter said. "And another characteristic of El Niño is that the Front Range is more than likely to be on the wet side."
