Latest forecast model ensembles from ECMWF and GFS converge on a high temperature near 13°C in Munich on May 15, driven by a persistent cool westerly flow channeling Atlantic moisture, fostering widespread cloud cover and scattered showers that limit solar insolation and suppress daytime heating. Trader consensus reflects this clustering, with 13°C at 32.5% implied probability edging 14°C at 25%, as minor differences hinge on the timing and intensity of precipitation—prolonged overcast skies could cap peaks at 12°C (18.5%), while brief clear intervals might push toward 15°C (15.5%). Deutscher Wetterdienst observations today confirm ongoing instability, cooler than May climatological norms of 18–19°C highs; expect refined guidance from afternoon model updates ahead of resolution.
