The merged AzShear is quite useful in this case of a large convective system moving through the region. While single radar is useful, the merged product provides a much better overview of the region. Areas of highest shear are readily identifiable and can then be interrogated further with reflectivity and velocity data. My confidence in the existence of a tornado where the merged AzShear is showing white & yellow on the left image is solidified with the corroborating details in the reflectivity and velocity data.
South of the main tornadic signature in velocity, adjusting the velocity for SRM indicates 2 other weak couplets, neither of which I have high confidence are tornadoes on the ground based on the AzShear products.
