As a steady rain fell Monday afternoon, Fourth of July celebrations around the region were canceled or postponed. But the city's marquee fireworks show in the Inner Harbor will go on as scheduled.

Rain moved into the region by 3 p.m., with about a quarter of an inch reported at Baltimore/Washington International Thurgood Marshall Airport by 6 p.m. Radar showed that bands of precipitation had moved east of the city by 6 o'clock, but more scattered showers were moving in from the west.


"There looks to be a window [for fireworks]," said Bryan Jackson, a meteorologist at the National Weather Service's Baltimore/Washington forecast office.

Some scattered showers and thunderstorms could pop up after the bands of afternoon rain move through, he said. Another half an inch to three quarters of an inch of rain is possible during the overnight hours as a warm front passes through the region.

In Baltimore, fireworks display organizers are preparing for wet weather. City officials said just after 5 p.m. that celebrations scheduled in the Inner Harbor, with musical performances starting at 7 p.m. and fireworks at 9:30 p.m., would go on as planned, so long as no thunderstorms move into the area.

"As long as it's just straight rain, we're good," said Tracy Baskerville, a spokeswoman for the Baltimore Office of Promotion and the Arts.

The U.S. Navy Band Cruisers had been scheduled to perform at the Inner Harbor amphitheater at 7 p.m. but would not go on until 8:30 p.m. because of the rain, Baskerville said.

Officials elsewhere made calls to cancel or postpone festivities.

In Dundalk, officials made the call Sunday night to postpone fireworks until Tuesday.

The Baltimore Symphony Orchestra said Monday afternoon it was canceling its "Star-Spangled Spectacular" performance scheduled for 8 p.m. at Oregon Ridge Park in Hunt Valley. The organization said ticketholders would be contacted via e-mail with more details.

Catonsville was holding its annual Fourth of July parade on Monday as planned, but the town's fireworks display has been postponed until Tuesday night.

Organizers of Towson-area fireworks, launched from Loch Raven Technical Academy, said those festivities were also postponed until Tuesday night.

In Annapolis, a 6:30 p.m. parade was canceled but a 9:15 p.m. fireworks show is set to go off even if it's raining, officials said Monday morning. But if there are thunderstorms, all activities will be postponed or canceled, they said.

For any celebrations that do go off, temperatures will be chilly. At 5 p.m., it was 71 degrees at BWI, some 15 degrees below normal. Temperatures were forecast to hold steady through the evening.
