Northern Arizona Chance of Rain Increasing Today - Tomorrow
Featured

15 May 2015   Dr. Curtis James

It’s cold for May. And it’s not going to warm up much in the near future.

Discussion: An unusually cool and unsettled weather pattern will continue as a large-scale trough will remain over the Southwest for at least the next week. Three back-to-back troughs will move through Arizona during this period, the first moving across the state today and Saturday dropping between 0.25 and 0.75” of rain across portions of northern Arizona (snow levels above 6,500’). Two more systems could affect the state next Monday-Tuesday and again next Friday to Saturday with at least a slight chance of measurable precipitation.

NWS Open House:The National Weather Service will host an Open House for the general public at their office in Bellement (about 13 miles west of Flagstaff) on May 30 (see the attached flyer). The emphasis of this open house will be fire weather, and you can also enjoy watching a weather balloon. Embry-Riddle’s Applied Meteorology program will present a booth at the Open House.

Weather Spotters:If any of you would be interested in becoming a trained weather spotter for the National Weather Service to help provide forecast and warning verification and ultimately help improve the accuracy and timeliness of weather warnings for your local area, you can complete a FREE online training athttps://www.meted.ucar.edu/training_course.php?id=23.
