Ideally, this product is plotted as a meteogram, showing the probabilities of each precipitation type for a specific location. The minimum value of precipitation is determined to be 0.1 mm/h. The product is based on NWP models (ECMWF, HIRLAM and GFS) and the best guess of the FMI’s meteorologists. Outside of Fennoscandia the product utilize only outputs of NWP models. The probabilistic forecast utilize poor man ensemble prognosis system (PEPS) including previous model runs.
