Trader consensus on Warsaw's March 28 high temperature clusters tightly around 13-14°C (53% combined implied probability), driven by converging 12Z ECMWF and GFS model runs forecasting mild southerly flow under a weak upper-level ridge, with peak heating midday. Differentiating factors include ensemble spread—ECMWF leans warmer at 14°C from stronger solar insolation and lighter clouds, while GFS edges to 13°C anticipating earlier marine influence and diurnally variable boundary layer mixing. Recent developments, like yesterday's observed +12°C anomaly versus March norms (~9°C), bolster optimism, though 10-20 hPa geopotential uncertainty could swing outcomes by 1-2°C; monitor IMGW hourly updates for resolution criteria based on official airport observations.
