Southern Arizona/far southeast California

A closed upper low west of the Baja Peninsula will become somewhat more progressive as it evolves into an open wave through early Thursday morning while approaching the northern Gulf of California. Preceding it, a plume of sufficient low to mid-level moisture across the peninsula and gulf will support periods of showers and embedded thunderstorms mostly across the northwest portions of Mexico and adjacent waters. Some of this activity will spread across the international border, mainly later this afternoon through tonight across southern Arizona. Severe thunderstorms are unlikely owing to meager buoyancy and weak low-level winds.
