The weather forecasts do not use probability percentages but, rather, specific terms that apply to a defined range. The correspondence between the probability ranges and descriptive terms is as follows:
| Probability | Term |
| 0 to 20% | Not excluded or no specific indication |
| 20 to 40% | Possible |
| 40 to 70% | Likely |
| 70 to 100% | Very likely or no specific indication |
A probability applies to a defined region (e.g. eastern Switzerland), i.e. the likelihood of occurrence is representative of the entire region and does not necessarily indicate the probability for a particular location.
Probabilities are sometimes accompanied by a term describing the geographical distribution of the phenomenon. This type of information is generally used for parameters of a random nature, such as sunshine, cloudor precipitation.
