"If the suck zone"
The WHAT????
"According to Rasmussen, "Early in a tornadic thunderstorm, the pressure falls due to increasing rotation. This causes the inflowing wind near the ground to accelerate as it rises toward the updraft. This is what our fictional counterparts in Twister called the tornado's 'suck zone'." A few thousand feet above the ground, this inflowing updraft of air collides with air overtaking the storm from the rear in a region where evaporating raindrops are cooling the air, causing a strong downdraft to form."
