Baltimore woke up Friday, March 6, 2026, to a gray lid of low clouds, patchy to locally dense fog, and temperatures stuck in the mid 40s (about 46°F). Visibility is reduced in low-lying neighborhoods and along the Inner Harbor, so the morning commute is likely to crawl. Light showers are possible on and off through the day, and highs should still top out near 50°F.
Foggy Mornings, Slow Commute
A Dense Fog Advisory is in effect into mid-morning for parts of the region, with the worst visibility west of the Blue Ridge. Conditions are expected to improve after 10 a.m., although fog could redevelop tonight. IFR to LIFR flight conditions are possible at area terminals, including BWI, and drivers are urged to use low beams and leave extra stopping distance, according to the National Weather Service Baltimore/Washington.
Afternoon Showers And Saturday Storm Risk
A backdoor front will keep a sharp temperature split in place today, holding the immediate Baltimore metro near 50°F while milder air lingers to the south and west. Showers become more likely after noon, and forecasters are watching for steadier rain and a few thunderstorms late Saturday into Saturday night, with the greater severe threat west of the Blue Ridge. For background on yesterday's fog and commute impacts, see how Baltimore's rush hour turned into a slow-motion slog.
Weekend Warm Up Then A Brief Cooldown
Forecast guidance points to a warm surge Saturday night into Sunday, with highs climbing into the upper 60s and low 70s early next week. Another front may bring showers by midweek. Calmer, sunnier stretches are expected Monday and Tuesday, but outdoor plans should stay flexible since the timing and the warmest corridor could still shift, according to the National Weather Service Baltimore/Washington.
What To Do Today
Give yourself extra travel time, use low beams in fog, and slow down on bridges and interchanges where visibility drops. Boat operators on the northern Chesapeake and tidal Potomac should be especially cautious: keep a GPS plotter on, monitor marine forecasts, and consider postponing nonessential trips until visibility improves.
