During Friday, severe thunderstorms will affect part of the northern Texas Panhandle to south-central Nebraska.

The risks from the storms include damaging wind gusts, large hail, flash flooding and a few tornadoes. However, locally severe storms can reach as far south as the Metroplex with high winds, hail and blinding downpours.
During Sunday, the main line of storms is forecast to slowly settle to the south and east of Metroplex. However, there may still be some areas in central and northeastern Texas that experience locally strong thunderstorms and the potential for flash flooding.
