Bright sunshine made for a pleasant afternoon in the Washington region Saturday, but not even hours of shirt-sleeve warmth could banish recent signs of the approach of winter.

At Dulles International Airport, the morning temperature fell to one degree above freezing Saturday. The 33-degree reading was the lowest since April, as was Reagan National Airport's 42-degree morning low.

The National Weather Service on Friday posted a frost advisory for northern and western suburbs. A comment posted Saturday on The Washington Post's Capital Weather Gang site reported "the lightest and briefest of early morning frosts" in Centreville.

In a sign of the times, the District's Department of Public Works advised last week that residential street sweeping will end for the season on Friday.

On Saturday afternoon, winter seemed remote, with temperatures in the 70s. But the area had just passed seasonal milestones. The amount of daylight dipped below 11 hours on Thursday; Saturday, the height of the sun dropped to less than 40 degrees.
