Warm and more humid air will continue to flow across Texas into Saturday.

During Friday, severe thunderstorms will affect part of the northern Texas Panhandle to south-central Nebraska.
During Saturday, building warmth will lead, in part, to severe thunderstorms from southwestern Wisconsin, Iowa and northwestern Illinois to north-central Texas.
The most intense storms are likely to focus over portions of Iowa, western Missouri and eastern Kansas. 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.
