The latest ECMWF 12Z operational run for May 5th unequivocally projects robust thermal advection across Southern Germany, pushing 850 hPa temperatures over Bavaria to an aggressive +14°C. A dominant upper-level ridge is establishing, fostering significant subsidence and clear-sky conditions conducive to maximum surface insolation. This synoptic setup, historically, correlates with high Tmax values. Both the ECMWF and ICON-EU deterministic outputs for Munich on May 5th are firmly in the 23-24°C range. GEFS ensemble guidance further corroborates, indicating an 85th percentile probability of exceeding 21°C, with the ensemble mean Tmax holding a tight 23.2°C. Sentiment: Local Bavarian forecasts are already signaling a marked warming trend, validating the model consensus for May 5th.
