Can storms produce there own cold air?

hello everyone , been getting some questions and also noticing on social media about this weekends storm being able to produce its own cold air. The process you are referring to is called adiabatic cooling. when a storm gets so strong at the low & mid levels a void in the atmosphere is created. To balance out this void , cold air is drawn into the center of the low from aloft and at the surface. Air warms adiabatically when pulled down , so the atmosphere must be unstable for this process to cool the lower atmosphere. bottom line here , you must have enough instability to produce a rapid cooling process , but keep warming from that sinking limited. FWIW , this is more advertised for precipatation intensity not changeover!
