Monday, July 27, 2026: Baltimore rolled out of bed into a wall of muggy, low‑70s air and is on track for a sultry start to the week, with afternoon highs near 88°F and humidity turning the city into a full-on sweat test by later in the day. Forecasters flag a slight chance of an isolated shower around early afternoon, with a growing chance of scattered showers and thunderstorms as the day wears on; any stronger cell could dump heavy rain and kick up gusty winds. Overnight lows only slip back into the low 70s, so evening plans might get briefly interrupted by passing showers or storms. If you are heading out, keep an eye on the radar and be ready to duck inside for a bit.
Afternoon Storms Possible
Humidity teaming up with a southerly flow will juice up the atmosphere this afternoon, bringing roughly a 35–40% chance of showers and thunderstorms, mainly between mid‑afternoon and early evening. Highs are expected to top out near 88°F with southwest winds around 0–5 mph, and any heavier downpour could wring out new rainfall amounts of about a tenth to a quarter of an inch. An umbrella will not be overkill for afternoon errands, as brief bursts of heavy rain could cut visibility on city streets, according to the National Weather Service.
Severe Threat Tuesday
The real troublemaker shows up Tuesday, July 28, as a cold front barrels through the region. Forecasts call for a high near 85°F and a 90% chance of showers and thunderstorms, with new rainfall totals of about a half to three‑quarters of an inch possible. The National Weather Service warns that "Damaging wind gusts continue to be the primary hazard type expected," and forecasters also flag a risk of large hail and a brief tornado along the surface low track during convective activity. South winds on Tuesday could gust into the 20s, so conditions may flip from calm to chaotic in short order during the afternoon and evening. Make sure you have a quick path indoors if warnings pop up and double‑check local alerts before heading out.
Tides And Boat Owners
Tidal anomalies working with persistent southerly winds have nudged water levels higher around the Severn River, and early Monday readings put Annapolis at or near minor flood levels while the National Weather Service hoisted a Coastal Flood Advisory for the morning high tide. Mariners and waterfront property owners should be ready for higher‑than‑normal tides and take precautions; NOAA Tides & Currents shows recent elevated readings for Annapolis. If your boat is sitting in the harbor, it is a good day to delay nonessential trips and stay alert for quick wind shifts and lightning.
Plan Ahead
Build in extra time for any afternoon or evening driving, tie down or bring in loose patio furniture, and keep a charger handy if you will be outside, since brief outages are on the table with stronger gusts. If you have outdoor events lined up later today or Tuesday, keep checking updated forecasts and county alerts so the weather does not end up making your plans for you.
