Dr. Orf's Alternative Theory on Tornadogenesis

Jul 2, 2014
The RFD is basically an extention of the FFD, there’s no real “clear” boundary between the two. The real difference is when you have a strong VPGF it will tend to bring down drier air from aloft hints the “Clear Slot”. I think as long as you have a source of baroclinic vorticity on either flank and a strong enough vertical pressure pertabation, then tornadogeneisis becomes increasingly more likely.
