With more rain in the forecast, Baltimore nearing pace for its wettest year on record

With more rainy weather in the forecast this week, Baltimore is on track for a potentially record-setting year of precipitation.

Through Sunday, there has been almost 51 inches of rainfall at Baltimore-Washington International Thurgood Marshall Airport in 2018.

That is 9 inches more than the region gets in a full year, on average.

So far, 2018 ranks second in the region’s record books for precipitation over the first three-quarters of the year. It is behind only 1889, with 51.17 inches of precipitation from January through September.

That total could be surpassed before this month is out.

Moisture-laden air that made for a rainy Sunday is forecast to bring more showers Monday, and then a pair of fronts are forecast to bring more unsettled weather through the end of the week.

Steady rain is expected Tuesday before a warm front lifts into the region Wednesday morning, and then a strong cold front is forecast to pass through Wednesday night, according to the National Weather Service. Brief heavy rainfall is possible as that front passes, and then more showers are possible into Thursday.

By the time skies begin to clear Friday, this September could itself rank as one of Baltimore’s wettest on record.

There has already been more than 7 inches of rain this month at BWI. September rainfall has surpassed 8 inches in Baltimore only 10 times on record.

Baltimore’s wettest year on record is 2003, followed closely by 1889. Both years saw more than 62 inches of precipitation.
