Darkening Clouds

Borders Region

These are the skies that made for interesting experiences while I was outdoors all summer on bicycle tours. Showers could pop up anytime unexpected, but often by the time one could get his raingear out, the shower had passed and it was sunny again. After several encounters, through experience, I would know which clouds and which skies justified bothering getting suited for rain. Would this cloud produce an all-day washout or simply a “turnip green shower”?
