Rest of the work week: Unsettled conditions continue

Jared Smith / May 25, 2026 at 10:26 PM

Unsettled weather will continue for the rest of the abbreviated work week as we remain on the periphery of Atlantic high pressure, with plenty of moisture available for the seabreeze and other boundaries to kick off showers and thunderstorms each day. Some much-needed rain will fall, and those chances will improve heading into next weekend.
