Russians had their meteor on Friday and astronomers their asteroid. At the same time, Washington beheld still another indication of the inexorable workings of the cosmos: signs of spring.

As measured at Reagan National Airport, the mercury soared to 60 degrees, Washington’s warmest reading this month. Also, Friday’s 6:59 a.m., sunrise was the first one earlier than 7 a.m. since late December, according to official figures.

For much of the afternoon, Friday showed the glow and blue-sky sparkle of spring, as the Northern Hemisphere continued tilting away from the gloom of winter, and the sun climbed higher.

With little swagger or suggestion of daring, many people shed winter coats. But before the sun set, dark clouds arrived and cold winds showed that spring may be coming, but it is not yet here.
