sun break
n.— «My son and his family arrived in Seattle in July and luckily got exposed to the city’s summer sunshine. They are now adjusting to its rainy season, meaning you put on your raincoat, unfurl you umbrella and keep going. Sunshine is so scarce in winter that weather reports refer to it as “sun breaks.”» —“Roberts: From Greensboro to Seattle, with love” by Rosemary Roberts News-Record (Greensboro, North Carolina) Dec. 1, 2006.
