Latest ensemble forecasts from the Finnish Meteorological Institute and ECMWF project afternoon highs of 16–17°C in Helsinki on May 17 under partly cloudy skies and light southerly flow, keeping trader consensus tightly clustered around those two outcomes. Subtle model differences in boundary-layer mixing, solar insolation duration, and thin high-cloud timing create the narrow spread that separates 16°C from 17°C, while May climatology near 15°C and recent spring warmth anomalies support the elevated probabilities. Resolution hinges on the official 24-hour maximum at Helsinki-Vantaa Airport, with the next FMI briefing tomorrow morning likely to refine any last adjustments before peak heating.
