Howdy Ossie,
Here's the latest to rake over us, viewed north westward from the bluff overlooking the Miss river downtown. That is a wall cloud in a single supercell storm with a 50,000 ft cap, 38 miles north to south and 32 miles across. As it was only moving 50mph as opposed to some clocked at nearly 90mph, it had for greater potential for destruction because of lengthy dwell time. We used tornado indexes (VTI) here, 9 means a funnel is lifting your roof top off.
This one started about 45 miles out bearing down on city center with a VTI varying between 7.5 and 8.8 and an incredibly defined bow echo which is where air is drawn in by convective effect to feed it. Many lost electricity and and much damage. Our city is known for its extensive tree canopy, 75 to 100 ft oaks with no tap roots essentialy sitting on top of the soil as clay prevents any root penetration. At this size with massive trunks rising sometimes 40-50 ft before the first branch, they succumb readily to wind and routinely obliterate anything in the path of their fall line, cutting houses to the ground. Averaging weather events on this scale in weekly intervals since early March here, it's the tree issue that is the most wearing for those exposed. My Vin's would be reduced to the film thickness of gold leaf if just one of many surrounding us came down.
