Answer:
Snow is difficult to predict due to several factors, including the variability of atmospheric conditions that lead to snowfall, the difficulty of measuring snow accumulation, and the fact that small changes in temperature can cause snow to change from rain to snow or vice versa. Additionally, forecasting snowfall requires accurate and detailed information about both the temperature and moisture content of the atmosphere, which can be challenging to obtain and interpret. All these factors contribute to the uncertainty and difficulty of predicting snow.
