The United States could be in line for an above-normal tornado season this spring in a repeat of what happened in 2011 when a La Nina weather pattern combined with an active jet stream to create record cold temperatures during the winter before the severe storms hit, meteorologists fear.
“Severe weather season is really a collection of several short weather events, and anticipating individual events at long lead times is usually tricky,” Sam Lillo, an atmospheric researcher at the University of Colorado Boulder, told CNN.
