In recent years the interest in the prediction and prevention of natural hazards, related to hydro-meteorological events, has increased the challenge for numerical weather modelling, in particular for limited area models, to improve the Quantitative Precipitation Forecasts for hydrological purposes. In mountain river basins where snow dynamics can affect both precipitation (snow accumulation) and runoff (snow melting), air temperature uncertainty has to be thoroughly investigated. The analysis focuses on two Piedmont basins, located in the North-West Italy. The aim of this work is to assess the reliability of a real time flood forecasting system, coupling meteorological and hydrological models, analysing the forecasting precipitation and temperature fields at different spatial scales, and in different weather conditions.
