1 Arizona Climate Summary December 28 Summary of conditions for November 28 November 28 Temperature and Precipitation Summary November 1 st - 11 th : November began with high pressure over the western U.S., which brought clear skies and warm temperatures over all of Arizona. 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. Another very cold lower pressure system swept through form the 9 th through the 11 th, dropping snow at the higher elevations, and lowering temperatures into the s and 5 s at the higher elevations, and the 7 s in the deserts. The north rim of the Grand Canyon received 4 of snow, while Bellemont, near Flagstaff received 3.2. Lower elevations received light to moderate rainfall. November 12 th - 24 th : By the 12 th, a strong high pressure system set up off the California coast, keeping the storm systems well north of Arizona, and bringing clear skies, dry conditions, and warmer temperatures to the state through the 24th. time temperatures rose into the s and 7 s in northern Arizona and at higher elevations, while the southern deserts and lower Colorado River had daytime temperatures in the mid to upper 9 s. 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 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.. Show Low received 1.8 of rain, Yuma 2.23, Tonto Natural Bridge 2.15, Seligman 1.93, Sedona 1.2, Prescott Airport.92, Phoenix Airport.49, Payson 1.77, Flagstaff Airport.97, Bullhead City 1.65, Canyon de Chelly.74, Bisbee 1.9, and Tucson Airport.28. In This Issue: Graphs of the November daily maximum and minimum temperatures, precipitation, and mean daily dew points for Flagstaff, Phoenix, and Tucson; graphs of 28 dew points and cumulative 28 precipitation for Tucson, Phoenix and Flagstaff; November climate statistics for Phoenix, Tucson and Flagstaff; daily maximum and minimum temperatures and precipitation for 7 stations across Arizona; maps of the mean maximum and minimum temperatures and precipitation across the state for November and for the calendar year January through November; maps of the departure from average temperature and percentage of average precipitation; graphs of the November precipitation for the period of record, and the average monthly temperature and precipitation for Phoenix, Flagstaff and Tucson. Climate calendars for Flagstaff, Phoenix, Tucson, Prescott, Winslow and Yuma, including daily and monthly normals and extremes, for each month of the year, can be downloaded directly from the State Climate website.

2 Flagstaff, Phoenix and Tucson. **Note: The discrepancy between the Statewise Temperature and Precipitation values for Phoenix, Flagstaff and Tucson and the daily values in their graphs are due to the reporting times. The Statewide Temperature and Precipitation values are taken at 5pm, while the official daily records at the airports are taken from Midnight to Midnight. Monthly Temperature and Precipitation for Flagstaff, Phoenix, and Tucson Maximum temperatures began the month near average across the state, and became significantly warmer than average in mid-november as a strong high pressure system dominated the western U.S. High maximum temperature records were set in Phoenix on the 17 th and 18 th. Nighttime temperatures were near or above average in all three cities, with a few high minimum records tied or set in Flagstaff, Phoenix, and Tucson. No precipitation records were set in Flagstaff, Phoenix, or Tucson. Flagstaff had only 6 days of precipitation, Phoenix had 2, and Tucson had 4 days. Flagstaff and Tucson are still below their annual average precipitation amounts, while Phoenix has had above-average precipitation so far in Flagstaff November Maximum Temperature Flagstaff November Minimum Temperature Max Record Max Normal Max Record Lo Max 28 Min Record HiMin Normal Min Record LoMin 1 Phoenix November Maximum Temperatures 75 Phoenix November Minimum Temperatures Max Record Max Normal LowMax 28 Min Record HiMin Normal Min LowMin Tucson November Maximum Temperature Max Record Max Normal Max Record Low Max Tucson November Minimum Temperature Min Record HiMin Normal Min Record Low Min 2
