Baltimore rolled into Wednesday, May 27, 2026, under muggy, near-70°F air, low clouds and pockets of fog, and the threat of storms building as the day goes on. Rain showers are likely this morning, with the main thunderstorm window expected between 11 a.m. and 3 p.m. The high should climb to around 82°F.
Afternoon Storm Window
Thunderstorms this afternoon could fire up quickly, packing brief but heavy downpours and damaging wind gusts. With soils already saturated in some spots, localized flooding is on the table. A Flood Watch remains in effect for parts of western Maryland and the upper Potomac Highlands through this afternoon. Most areas are expected to see a quarter to a half-inch of new rain, with isolated higher totals possible, according to the National Weather Service Baltimore/Washington.
Timing And Rainfall
Forecast guidance points to the highest odds of thunder around midday, with hourly chances peaking from roughly 1 p.m. to 3 p.m. Showers and storms should wind down by late evening, though a chance of additional showers hangs on into the overnight hours before 4 a.m.
Commute And Outdoor Plans
Drivers should be ready for wet roads, ponding in low spots and reduced visibility in heavier downpours. Plan on a slower-than-normal afternoon commute and have a backup plan for outdoor activities in case storms roll through at peak heating. Avoid driving through standing water and keep an eye on radar updates and local alerts, since conditions can change in a hurry.
Clearing By Thursday
Once the front pushes through, drier air filters in on Thursday with afternoon highs near 80°F and gusty north winds. A dry, seasonable stretch is expected into the weekend. For the latest watches and timing, check updates from the National Weather Service Baltimore/Washington.
