Mexico City's May climatology consistently shows mean maximum temperatures hovering around 27-28°C, making 27°C a highly attainable threshold. Current NWP ensembles (GFS, ECMWF) for May 5 project a robust high-pressure ridge leading to clear skies and high insolation. 850mb thermal profiles indicate strong warming potential, pushing surface temperatures to meet or exceed the 27°C mark. This dry season thermal buildup is well within expectation. 90% YES — invalid if an anomalous southerly advection of cloud cover develops.
