Click on the thumbnail graphic for the 2003 South Platte Basin High/Low graph. Check out the big snowstorm around St. Patricks Day in 2003. Snowpack that year was ahead of the prior year when that storm hit. All talk of drought ceased afterward. I’ve also posted thumbnails of the current U.S. Drought Monitor map and the current Climate Prediction Center drought forecast map.
From the Associated Press via The Denver Post:
March is a make-or-break month for relieving drought conditions in Colorado. State climatologist Nolan Doesken says a series of snow storms or one monster blizzard, like the one in 2003, would go a long way to improve conditions along the Front Range and Eastern Plains. The month is traditionally a wet one. But last year the state dried out during an extremely dry and warm March, which also marked the start of a deadly wildfire season…
Doesken said this week’s series of storms benefited any areas that got at least 7 inches of snow, the equivalent of about a 1/2 inch of water.
