Around 2120Z – interesting structure on a storm SE of KMXX.   Can see in Azshear – inflow from the south immediately ahead of the gust front.  However, behind this feature – can see an area of enhanced Azshear.  Question would be – how much would the PBL be worked over – cooled – and how might that influence tornadic potential?  Yet – another easy depiction on what is going on with storm evolution.
