RAIN FALL
Terms such as slight chance of rain (10 to 20%), chance of rain (30 to 50%) or rain likely (60 to 70%) are used when there is uncertainty of receiving measurable precipitation anywhere in the forecast area (such as Eastjutland). For instance, if there is only a 30 to 50 percent chance that rain will fall anywhere in Eastjutland, then the forecast will call for a chance of rain.
