Isolated thunderstorms are possible along the Gulf Coast on Saturday. Severe storms are not expected. ...Synopsis... Diffuse mid-level troughing over the eastern US is again expected Saturday as a secondary shortwave trough moves out of the Rockies and over the Plains. Ahead of the western trough, a lee low will deepen over parts of the central Plains, north of a stalled front along the Gulf Coast. High pressure over the southeastern US will weaken as a cool polar air mass slowly modifies. As the surface low moves south toward the Gulf Coast late Saturday, weak inland moisture advection is expected over parts of coastal southeast TX and southern LA into early Sunday. Isolated thunderstorms are possible given the ascent and weak buoyancy that develops. However, most if not all of the convection should remain offshore. Thus, while some elevated storms are possible inland, the severe risk appears low. ..Lyons.. 12/04/2025 $$
