Great viewer pics that matched up with 14 Dual Doppler with the supercell thunderstorms that fired up which prompted tornado warnings. These spaceship looking clouds are quite rare in October but tell a severe weather story.
The picture below illustrate veering winds/wind shear...a very unstable atmosphere. The winds are turning clockwise rapidly with height. The surface winds were gusting out of the southeast, wind at the mid-levels were increasing from the southwest, and winds at the upper levels were driving out of the west/northwest. Weather in a 3D environment.

The picture below illustrates the rear-flank downdraft part of the thunderstorm. The cold...dense air descending through the back of the thunderstorm. You can observe the rain shaft to the right. This might look harmless...but tornadoes can form on the southwest side of the storm...many times after it rains.

The photo below illustrates the front of the thunderstorm were you can observe shelf clouds and the gust front. With this supercell storm, cold...dense air moving through the front of the storm.
As the shelf cloud passes, expect an abrupt wind shift and increasing winds.... followed by heavy rain or hail. Wind gusts on Monday...once the shelf cloud has cleared....caused downed trees and power outages. However, zero confirmed tornadoes.
