Rainy stretch nearly matched Hurricane Sandy's deluge

Baltimore's stretch of rain from late last Wednesday night through early Sunday poured a deluge that came a quarter of an inch from matching Hurricane Sandy's rainfall total in the area.

Sandy brought 6.67 inches of rain to Baltimore-Washington International Thurgood Marshall Airport from Oct. 28-30. (The rain was heavier on the Eastern Shore, however, where many areas saw as much as 12 inches, including the town of Bellevue, which saw 12.83 inches, more rain than anywhere else during the historic storm.)

To compare an equal period of time, 6.42 inches fell at BWI from Thursday through Saturday. Rain was also measured Wednesday at the airport, 0.07 inches.

In a normal October, 3.33 inches of rain falls at BWI, while the record for the wettest October in Baltimore is 9.23 inches set in 2005.

That erases concerns of a developing drought. According to the U.S. Drought Monitor, 70 percent of Maryland, including all of the Baltimore region except Harford County, was considered "abnormally dry" as of Tuesday, but that is likely to shrink or disappear when the map is updated with the next week of data, to be released Thursday.

According to National Weather Service models of the precipitation that fell across the state over the past week, the heaviest rainfall was in the western suburbs of Baltimore, including parts of northern Anne Arundel County, western Baltimore County and Carroll and Howard counties. Rainfall totals are estimated in the range of 6-8 inches.

They include reports of 6 inches near South Gate in Anne Arundel County; 5.53 inches near Reisterstown; 3.74 inches in downtown Baltimore; 6.36 inches near Millers in Carroll County; 7.6 inches near Thurmont; and 6.66 inches near Ellicott City.
