The wettest May 26

SUN PHOTO/Frank Roylance 

Lots of records broken on Tuesday as Gulf and Atlantic moisture continue to flow into the region and run up against the stalled cold front draped across the Northeast.

BWI recorded 2.28 inches yesterday, washing away the previous record for a May 26 - 1.72 inches, set way back in 2001.

There was a new record set, too, at Reagan National Airport. They received 1.65 inches, beating the old record of 1.49 inches set there in 2003. And out at Dulles International, they more than doubled the old record of 1.59 inches, set in 2002. The total at Dulles yesterday was 3.59 inches.

We have now erased the rainfall deficit accumulated since the first of the year at BWI. The year-to-date total is 17.95 inches, beating the long-term average of 16.68 inches. But we still trail last year's total of 19.78 inches through May 26.

There are no sunny days in the forecast until Saturday. But while we will likely see drizzle and showers and perhaps some thunderstorms for the rest of the work week, they are not likely to produce to sort of rain some of us saw yesterday.

The rain was spotty. Here are some of the heaviest totals from across the region:
