Rapid intensification of jet stream winds and the evolution of a large scale trough across the central part of the U.S., in concert with an unusually warm and moist air mass more typical of springtime, led to the development of widespread strong to severe thunderstorms during Tuesday and continuing into Wednesday. Storms produced 3 short lived tornados in far Eastern Oklahoma and Northwest Arkansas Tuesday afternoon.
