Baltimore woke up to thick patches of fog and swampy humidity on Monday, July 6, 2026, with early morning temperatures stuck in the mid to upper 70s and dew points parked in the low 70s. The city is expected to warm into the upper 80s, and there is a solid chance of scattered showers and thunderstorms, especially this afternoon. The heaviest rain is expected late in the day, with storms capable of dropping about one half to three quarters of an inch of rain in a short burst. That is enough to set up localized flash flooding in poor drainage spots and low-lying streets.
Morning Fog and the Commute
Patchy fog and low clouds could hang around through midmorning, cutting visibility on surface streets and bridges. Drivers should keep headlights on, give themselves extra stopping distance, and expect slower-going until the sun can burn off the low clouds. Light east winds of about 1 to 6 mph will limit mixing early in the day, which means the fog may be stubborn in spots.
Transit riders are not off the hook either. Bus and rail delays are possible once any heavier downpours move in, so riders are urged to keep tabs on service changes by checking MTA Service Alerts for updates.
Afternoon and Evening Threat
Showers and thunderstorms are most likely between about 2 p.m. and 8 p.m. Monday, with the strongest cells expected to flare up in the 3 to 4 p.m. window and again later this evening. A Flood Watch is in effect from late afternoon into the night. The National Weather Service warns that “hourly rainfall rates could push into the 2 to 3 inch range” in the most intense storms.
Slow-moving storms and repeated rounds of heavy rain over the same neighborhoods could quickly overwhelm storm drains and small waterways. Flash flooding of creeks, poor drainage streets, and underpasses is possible, so drivers are urged to avoid going through standing water, no matter how shallow it looks…
