A pause in precipitation ended Baltimore's rainfall streak at 15 days

Baltimore's rainfall streak ended at 15 days on Wednesday.

Despite more cloudy and damp conditions, it did not rain in Baltimore on Thursday, ending a 15-day precipitation streak two days shy of tying a record.

At least a trace of rain fell every day at Baltimore/Washington International Thurgood Marshall Airport from April 27 through Wednesday. Foggy, misty or overcast conditions were reported throughout the day Thursday, yet no precipitation was recorded at BWI.

Only rainfall at BWI counts for Baltimore record-keeping purposes.

Baltimore's longest period with at least a trace of rain falling every day is 17 days, set from March 31-April 16, 1935. (Back then, the point of record was the U.S. Customs House downtown.)

There were some close calls during the recent span. Only one-hundredth of an inch fell on an otherwise pleasant Mother's Day on Sunday, and on Monday, some rain was observed, but not enough to measure more than a trace.

But it has been wet, to be sure. Over the 15-day stretch, 3.68 inches of rain fell, about a month's worth. That is half an inch more rain than normally falls in the month of April and about a quarter of an inch shy of normal rainfall for the month of May in Baltimore.

Dry conditions had been starting to develop across some parts of the state, and a rainfall surplus for the year to date had nearly vanished. Now, rainfall is running a few inches ahead of normal again.

Of course, the rain did not stop for long. A steady rain Friday dropped 0.05 inches at BWI by noon. More showers are likely Saturday.

While sunshine is expected to break through Sunday and Monday, it will be more than 10 degrees colder than normal for this time of year, with highs in the lower 60s. Then, showers are likely again from Tuesday through Thursday, at least.
