On the 2 nd, a cold front moving across the western U.S. brought light rain showers to north central Arizona, including Flagstaff, Cottonwood, Sedona, and Bellemont. A second, stronger cold front moved through on the 5 th, lowering temperatures into the upper 7 s across the state, and dropping.2 of rain at Page, and.5 at Canyon de Chelly in the northeast. High pressure and clear skies returned to the state on the 7 th and 8 th, with temperatures climbing back into the lower 8 s in the southwest deserts.

The relative heat wave melted most of the snow that had fallen earlier in the month. November 25 th 3 th : On the 25 th, a cut-off low pressure system (an area of low pressure with a closed circulation, cut off from the jet stream, so that it moves very slowly, eventually losing energy as the moisture is lost through rain or snowfall http://www.usatoday.com/weather/tg/wcutoffs/wcutoffs.htm). This system had significant moisture from the eastern tropical Pacific Ocean, and brought heavy rain to the lower elevations and snow to the higher elevations. The system remained over Arizona and the southwestern U.S. until the 3 th, when if finally dissipated. The north rim of the Grand Canyon had 4. of snow while the south rim had 1.5, Williams had 2., and Mount Lemmon had 4..
