Two of Washington’s wettest days in months followed two of the area’s finest days in at least as long, as the total Thursday-Friday rainfall amounted to about 2.5 inches.

As measured at Reagan National Airport, about 1.65 inches fell Friday alone, more than any day here since October.

High water temporarily slowed traffic, and trees toppled in spots.

Inclement weather was partially blamed for Friday’s 20-mile traffic backup on the way to the Chesapeake Bay Bridge. Washington Nationals games were postponed on successive nights.

The two gray and soggy days seemed the antithesis of Tuesday and Wednesday, with their bright sunshine, blue skies and no more than the merest hint of humidity.
