  2. Max and Min Temperature Climo for SLC (red) and Ouray (blue) 1981-2010 • Both basins climos show ‘cold pools’ resulting in colder December-February average temperatures than would be the case at mid-slope locations. • The ‘cold pool’ climatology is colder in Ouray than SLC • during the Dec-Feb period • with nocturnal inversions • particularly stronger • Hypothsized cause the longer duration of Uintah Basin CAPs and associated snow cover Max temp Temp C⁰ Min temp Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec
