Truckers could hit spots of powerful winds and big hail in the southern Plains the next two days.
A cold front moving out of the Rockies will move across the Great Lakes, the Great Plains and the Mississippi Valley. A strong clash of cold and warm air at the ground, instability aloft and plenty of moisture will trigger areas of storms stretching from the Midwest to the Gulf Coast.
Some storms may reach severe limits, especially Wednesday from Oklahoma to northeastern Texas. This is where storms could produce large hail at least 1 inch in diameter, as well as 60-plus mph wind gusts and isolated tornadoes.
