Most of the showers and thunderstorms are on the way out of the region currently, leaving only BRO to be affected at the time of writing. However that should come to an end soon. A mixture of VFR to MVFR ceilings should occur for the next several hours before going to mostly VFR with light winds for the rest of the afternoon. Some MVFR ceilings could creep in again during the overnight hours, but should quickly turn back to VFR a little after sunrise tomorrow.

MARINE

Issued at 145 PM CDT Wed May 27 2026

Hazardous marine conditions are expected to persist through most of tonight in the wake of the line of convection that passed through this morning.

Winds are generally expected to be between 20 to 25 knots with some stronger wind gusts possible up to 30 knots. However, adverse conditions are likely to occur behind the front as well as the winds will take some time to come down below 15 knots. By tomorrow afternoon, favorable conditions should return through the weekend. By Monday, the environment will become more favorable for the development of showers and thunderstorms that could produce some heavy rainfall and locally elevated winds and seas.
