As an upper-level short-wave trough advances over the Rockies, shear and instability will be adequate for supercell development in the high Plains this afternoon and evening. A tornado has already been reported in the recent hot-spot of Goshen County, Wyoming, along with softball-sized hail!

A tornado watch is currently in effect for northeast Colorado, western Nebraska and southeast Wyoming, along with a scattering of severe thunderstorm watches from the Texas Panhandle to the middle Ohio River Valley to the Florida Panhandle. Extremely large hail and tornadoes are most likely in the high Plains, with damaging wind and severe hail being the main threat farther south and east. Storm chasers are already in the field tracking storms, so be sure to follow their progress on the Live Video tab!
