(TheWeatherSpace.com) — A storm system ejecting out of the Southwestern United States today will set the stage for severe weather across the plains on Saturday.
As of right now there are several dynamics coming into play that will promote severe thunderstorms with mainly a hail and wind threat. Strong instability along the dryline will promote rapid growth around the Texas and Oklahoma borders, west and southwest side of the state.
These storms will be developing in an area of increasing low level shear by the evening which could support a brief tornado chance. There are dynamics such as boundary layer stabilization that will diminish the tornado probability toward the evening and early night hours so again this window is very small.
