Wednesday, April 22, 2026, is starting off cool and gray in Baltimore, with temperatures sitting around 536F under mostly cloudy skies and some light showers. A cold front sliding across the region is expected to kick things up a notch, with showers and thunderstorms likely from the morning into early afternoon. Forecasters are eyeing the main action window between about 8 a.m. and 1 p.m.
Timing And Impacts
Showers and thunderstorms are most likely between 8 a.m. and 1 p.m. on Wednesday, April 22, 2026, with the high topping out near 726F. Most neighborhoods should only see light rain on the order of a tenth of an inch or less. That said, forecasters caution that a couple of stronger storms could crank out small hail, brief heavy downpours and wind gusts over 45 mph, enough to send unsecured trash cans rolling and slow the morning commute.
Winds are expected to turn to the northwest this afternoon, which should help settle things down, and most spots are projected to quiet down by this evening. According to the NWS Baltimore/Washington, residents should keep an eye out for any isolated stronger cells that pop up this morning.
Tides, Boats And The Waterfront
Forecasters are also watching the water. Rising tidal anomalies could trigger Coastal Flood Advisories for low-lying spots around Annapolis and Havre de Grace during today’s high tides. Waterfront parking lots, boat ramps and docks are the most at-risk if water levels push up a bit higher than usual.
NOAA tide guidance shows a high tide near 2.9 feet at Havre de Grace this afternoon, and when that lines up with onshore flow it could be enough to cause minor nuisance flooding in exposed areas. Small craft advisories are posted on parts of the Chesapeake through the morning, so boaters are urged to secure loose gear and steer clear of more exposed waters when the winds pick up, in line with local guidance from tide and forecast offices.

Midweek Warmup Then Cooler Weekend
Once today’s front slides through, temperatures are expected to rebound for the middle of the week. Thursday looks warm and mostly sunny, with highs climbing into the upper 70s near 786F. After that, a backdoor front is poised to drag cooler air back into the region and bring another round of showers for the weekend…
