A powerful Pacific low pressure system, accompanied by a strong cold front, pushed east across south central Arizona during the early morning hours on November 29th. Due to elevated levels of both wind shear and instability, the cold front spawned a pair of tornadoes which moved northeast through communities to the north of central Phoenix, including Deer Valley, Glendale and North Scottsdale. The tornado that moved across Deer Valley was short lived, with a narrow path width, and was classified as an EF0. The second tornado that moved through North Scottsdale area had a path length over 8 miles, produced significant damage and was classified as an EF1.

A powerful Pacific upper level low and associated cold front moved east across central and northern portions of the greater Phoenix metropolitan area during the early morning hours on November 29th.

According to a NWS storm survey, the tornado had a path length more than 8 miles and was estimated to be an Ef1 in strength. The tornado began just west of Phoenix Mountain Park and ended near the west side of the Scottsdale TPC Golf Course. There were a number of damage reports associated with the tornado along its path.
