Baltimore started Tuesday, June 23, 2026, under gray, muggy skies, temperatures lingering in the low 70s, and a light mist hanging in the air. The calm, however, is expected to be temporary, with scattered morning showers set to grow into a broader round of rain and thunderstorms later in the day and highs near 79°F.
Afternoon Downpours Could Dump Heavy Rain
Scattered showers are likely between about 8 a.m. and 11 a.m., followed by a more organized stretch of showers and thunderstorms this afternoon, still with a high near 79°F. According to the National Weather Service, some spots in southern Maryland, especially Calvert and St. Mary's counties, could see locally heavy rainfall of up to 3 inches or more in a short period. A few storms could pack damaging wind gusts, mainly between about 2 p.m. and 7 p.m.
Boaters On Alert As Small Craft Advisories Spread
Small Craft Advisories are up for much of the Chesapeake Bay, the Patapsco and Baltimore Harbor, and the tidal Potomac, with advisory times varying by marine zone through tonight and into Wednesday morning. The National Weather Service notes gusts of 15 to 30 knots in some areas and warns that conditions will be hazardous for small craft. Boaters are urged to delay trips and make sure any loose gear is secured before the worst of the weather moves through.
How This Could Snarl Your Commute And Plans
Heavier downpours may quickly slick up the roads and cut visibility, so drivers should expect slower trips and leave extra time, especially this afternoon and early evening. Outdoor plans may need a backup option as storms pass through. Showers are expected to taper off from west to east this evening, with lows near 63°F on Tuesday night, and brighter, warmer weather is on tap Wednesday and into the end of the week.
Staying Weather Aware
Local conditions can change fast when thunderstorms bubble up, so it pays to keep an eye on the latest watches, warnings, and zone-specific advisories before heading out. If you are planning time on the water or running outdoor events, check updated marine messages and forecasts from the National Weather Service for the most current timing and hazard details.
