Early Tuesday, light rain fell in Washington. It was not enough to measure, but it went into the records as a “trace.” It meant that we could claim a continued wet streak.

With Tuesday’s trace of rain, it became possible and plausible to say that raindrops — possibly many of them, or maybe only a few — fell from our skies on five successive April days.

At Dulles International Airport, a trace also fell. There it meant raindrops came down on six straight days. That may enhance expectations for May flowers.

From the Wonderopolis website, we learn that a connection between this month’s moisture and next month’s efflorescence has a long history, traceable to a line in a 1610 poem that reads: “Sweet April showers, do spring May flowers.”

It was not clear whether “spring” was intentionally used in a double sense. But Tuesday was a pleasant spring day — cloudy in the morning, sunny in the afternoon.
