The plots below show the 24-hour precipitation from 8 November 18z to 9 November 18z for ECMWF HRES. The first plot shows the observations. Please note the observation of 37 mm over Stockholm, either indicating a very localised maximum or observation errors for that observations or the nearby ones (heavy snowfall is problematic for automatic stations). The model developed convection over the warm sea in all forecasts but missed the amplitude of the event over Stockholm.
