St. Patrick's Day Climatology for Eastern Utah and Western Colorado

Let's take a look at some "Lucky Data" (aka St. Patrick's Day Climatology) for selected cities across eastern Utah and western Colorado. By far the most impressive St. Patrick's Day took place in 1981 when a late season snowstorm dropped 7 inches of snow in the Aspen area with 6.5 inches in Meeker. Although some snow in the Aspen area in 2022 just surpassed that 7.0 inch record. The lowest minimum temperature on St. Patrick's Day was -7 degrees which occurred in the Meeker area in 1924. The warmest temperature of 82 degrees occurred in the Moab area in 2007.
