Recent meteorological forecasts from the European Centre for Medium-Range Weather Forecasts and the Italian Meteorological Service indicate a stable high-pressure system over northern Italy, supporting a maximum temperature of 21°C in Milan on May 17 with high model consensus and limited variability through peak heating hours. This aligns with May climatological norms for the region, where daily highs typically range 19–23°C under anticyclonic conditions and moderate southerly flow. Trader consensus at 98% for 21°C reflects real-time integration of observational data and ensemble outputs, though unexpected increases in cloud cover, localized wind shifts, or measurement discrepancies at official stations could still shift the recorded high by 1–2°C before resolution.
