Weather Extremes and Event Disruptions
On July 4, 2026, a record-breaking heat wave and severe thunderstorms struck the Baltimore metropolitan area. Temperatures climbed to 102 °F at Baltimore-Washington International Thurgood Marshall Airport, surpassing the prior 100 °F record set in 2002. Wind gusts of 60-70 mph downed trees and power lines, prompting the cancellation or delay of several Independence Day events, including the Cherry Hill Arts & Music Waterfront Festival, the Pier Six Pavilion concert, and the Pratt Street Market @ Night. The Inner Harbor fireworks display was postponed by about half an hour but ultimately proceeded.

A severe thunderstorm watch remained in effect until 10 p.m., forecasting hail, damaging winds, and frequent lightning. The storm system also produced flash flooding, a four-alarm fire in Baltimore, and widespread power outages.
