WebA supercell is a long-lived (greater than 1 hour) and highly organized storm feeding off an updraft (a rising current of air) that is tilted and rotating. This rotating updraft - as large as 10 miles in diameter and up to 50,000 feet tall - can be present as much as 20 to 60 minutes before a tornado forms. WebWhen a rear-inflow jet descends to the surface (essentially a downburst), the stage is set for a portion of the squall line to bulge forward in response to the surge in low-level winds.
