Central Arizona Severe Weather and Flooding

October 6, 2015

Updated: 1:00 pm MST October 13, 2015

A strong, slow moving cold low pressure system pushed towards central Arizona during the morning hours of Tuesday, October 6th. Sufficient breaks in cloud cover during the late morning allowed the atmosphere to become modestly unstable, and supportive for early afternoon thunderstorm development. Wind shear (that is, the measure of changing wind speed and direction with height) in both the low levels and through the middle of the atmosphere was unusually strong for the area. Developing thunderstorms quickly became well organized with supercellular characteristics producing severe weather and flooding across portions of central Arizona.

Thunderstorms first developed west and south of the Phoenix metropolitan area, but quickly started erupting closer to the western suburbs by noon. Several clusters of strong storms began pushing outflow boundaries towards the Buckeye/Avondale areas, with strong updrafts maintaining storm structure. A couple of these colliding boundaries interfacing with the leading edge of thunderstorm updrafts and low level shear led to at least one landspout tornado in the Buckeye area. A landspout is a violently rotating column of air in contact with the surface of the Earth that ascends to a growing cumulus or cumulonimbus cloud. Landspouts are typically not associated with organized storm-scale rotation and therefore do not arise from a wall cloud (visually) or supercell thunderstorms. Landspout speeds vary from 40 mph for the weakest, and up to 200 mph for greater for the most violent.

Given the impressive wind shear profiles, these storms and their associated outflow boundaries were very picturesque moving through the Phoenix metro. Several excellent pictures were sent along, and you may click on any of the images below for full sized versions.

This wasn't the only storm of the day though. A far larger and more intense supercell erupted near Casa Grande later in the afternoon. A very notable mesocyclone developed within the core of this storm, and the updraft strengthened such that very large hail was circulated through the storm. Reports of golf ball sized hail were received on the eastern edges of Casa Grande, and radar imagery and pictures received implied this storm was more like a storm experienced in the Midwest versus Arizona. Below are radar loops of the base reflectivity and volumetric scans of this intense storm showing the large hail being vaulted well towards the top of the storm.

Localized heavy rainfall also produced flooding through parts of the Phoenix metro and outer suburbs. While highly variable across the city, some isolated locations on the west and north side of town received over 1.50 inches of rain in an hour Tuesday afternoon. Below are county and city images depicting the daily rainfall Tuesday.
