As red flag warnings crop up across wide swathes of West and North Texas this week, a section east of Dallas-Fort Worth could see another kind of risk on Wednesday afternoon: punishing severe storms.

A “potent” weather system will enter North and Central Texas on Wednesday, steering the development of a dryline, according to the National Weather Service Fort Worth. A dryline is the boundary separating dry and moist air masses, where severe thunderstorms often develop.

A First Alert Weather Day is in effect today for a red flag warning and the low chance of isolated storms in the late afternoon.
