Dec 23 2015 Tornado Information (Graphic and Survey information)

National Weather Service Memphis Damage Survey for December 23, 2015, Tornado Event

Overview of Event:

A strong system with record warm temperatures along with impressive upper level wind fields provided the ingredients to produce 5 tornadoes across the Mid-South on Dec. 23, 2015, including two long tracked violent tornadoes.

Below is the morning surface analysis map showing a strong low pressure system over Kansas with an occluded front and cold front extending to the south with a stationary front extending east. 

The warm sector, defined by the area between the fronts, had temperatures at 6 a.m. local time (CST) in the mid-60s with dew points in the low 60s. The very moist airmass, especially for December, provided the fuel (instability) needed for robust storm development and eventually deadly long lived tornadic supercells.
