'Bright intervals.'

On Oct. 14, 1987, the British national weather service, among the world's best, issued its forecast for the following day: "Light showers, bright intervals and moderate winds."

CHAPTER 10 Those gray and stormy days were, like my life, punctuated by what the weather men call "bright intervals."

Bright intervals are possible and apart from the chance of a light shower it should stay dry milder than of late with a top temperature of eleven celsius fifty two fahrenheit in a moderate south easterly wind.

One may say, for example, that certain English expressions belong to the official style of weather forecasting ( "bright intervals", "scattered showers", etc), while other expressions ( "lovely day", "a bit chilly", etc) belong to the style of everyday conversational remarks about the weather.
