| Episode Narrative | 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. The tornadoes did not result in any injuries or fatalities. Most of the damage reported came in the form of downed trees as well as roof damage. The tornadoes occurred around 0400MST. |
| Event Narrative | 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. Due to elevated levels of wind shear and instability, the front generated several tornadoes in the Phoenix area, including one that tracked to the northeast from eastern Glendale into portions of north Scottsdale. 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. Many of them were related to downed trees including some with diameters up to 3 feet across. A trained spotter 4 miles west of North Scottsdale reported that some trees fell on vehicles causing damage. Additionally, there were reports of roofs removed and damaged along the path of the tornado. Finally, about 6 miles east of Glendale, Channel 3 TV reported that a very large tree fell on a carport and caused it to collapse upon a car. The fallen tree was just south of Northern Avenue, between 7th and 3rd Avenues. Fortunately there were no reports of any injuries or fatalities. |
