Recent ensemble forecasts from the European Centre for Medium-Range Weather Forecasts and Germany's DWD indicate a daytime maximum of 17–19 °C in Munich on May 19, aligning with the tight clustering of market-implied odds around those outcomes. An active Atlantic frontal system is expected to deliver variable cloud cover and scattered showers, which can limit solar heating and cap temperatures near 17 °C if precipitation arrives earlier than modeled. Conversely, brief clearing periods could allow modest warming toward 19 °C under the same mild air mass. These short-range uncertainties, typical this close to the event, explain why probabilities remain distributed across the three central bins rather than converging on a single value.
