Baltimore could set a record this week for consecutive days of rain.
Through Sunday, it had rained for 12 straight days at Baltimore/Washington International Thurgood Marshall Airport, starting April 27. A total of 2.66 inches of rain fell over that span.
A sunny Mother's Day on Sunday nearly broke that streak, but 0.01 inches fell before the sun rose.
Baltimore could tie a record for consecutive days of measurable rain (at least 0.01 inches) on Tuesday, and break it on Wednesday.
The longest streak on record is two straight weeks of measurable rain from Aug. 10-23, 1873, according to the National Weather Service's Baltimore/Washington forecast office.
No rain accumulation had been reported at BWI on Monday as of noon, but there was light rain threatening to keep the streak alive. More chances for showers are forecast Tuesday and Wednesday.
When considering streaks that include days with at least a trace of rain (when rainfall is observed but less than 0.01 inches of precipitation is measured), the record is 17 days, from March 31-April 16, 1935, according to the weather service.
A record has already been set in Washington, D.C., The Washington Post's Capital Weather Gang reported, with 13 straight days of rain there.
