Setup
On the morning of May 1, 2014, the weather setup was ripe for an extremely dangerous weather event across the Midwest. The storm system which produced the previous event was weakening as pushed into Texas. Wind fields over the Midwest were very strong, and at very low levels. A secondary cyclone swung down from the rockies during the late morning which created additional destabilizing of the atmosphere. By early afternoon, the weather system set up perfectly for a severe weather outbreak. The weakening storm system along the coast let out a large area of outflow across Texas, which met with a cooler invading air from the west coast. Then, storms erupted over central Texas, Oklahoma, Kansas, Missouri and Arkansas. Supercells dropped several large tornadoes over the miswest.
