Baltimore is getting the classic summer two‑for‑one this week: a pretty solid Sunday, then a potentially rough Tuesday as stronger storms move in.
The city woke up mostly cloudy and muggy on Sunday, July 19, 2026, with temperatures in the mid 70s, about 77°F, and a stronger, sunnier afternoon on tap. Expect highs around 87°F with northwest breezes of 6–9 mph, so it will feel like a warm summer day without extreme heat. If you are picky about the heat, aim outdoor plans for the morning or late afternoon when it is a bit more comfortable.
Afternoon and Tonight
Skies should gradually clear through the morning into a mostly sunny afternoon, with peak heat in the mid to upper 80s and lower humidity by evening. Tonight is expected to be mostly clear with lows near 67°F and light north winds, a relatively comfortable night compared with some of the recent July heat. A stray shower is possible this morning, although precipitation chances remain very low today.
Midweek Storm Threat
A strong cold front is forecast to move through Tuesday, July 21, 2026, bringing a high chance of showers and thunderstorms, with highs near 88°F and widespread precipitation chances around 80–90%. According to National Weather Service guidance, damaging straight line winds and localized flash flooding are possible with the most intense storms, and the threat could linger into Wednesday, July 22, 2026. If you have outdoor plans on Tuesday, build in backup options and be ready for later day severe thunderstorm warnings.
Impacts and Preparedness
Southerly channeling ahead of the front may raise bay and tidal levels Tuesday, with water levels possibly approaching minor flood stage at Annapolis, so boaters and anyone along the water should keep a close eye on conditions. Per the city's Code Red release, cooling centers and other resources are available to vulnerable residents this summer, with details in the city release at Baltimore City. Check updated forecasts and consider moving outdoor events if thunderstorms look likely Tuesday afternoon into the evening.
Plan Ahead
Bottom line, enjoy the mostly sunny and warm weather today, but keep an eye on forecasts for Tuesday, July 21, 2026. Have a quick plan for sudden storms, move electronics indoors, secure loose patio furniture, and if you are on the water or the roads, be ready for gusty winds and brief heavy rain.
