Climatological mean for May in CDMX trends 26-27°C. Current synoptic pattern indicates weak high pressure, favoring strong diurnal heating. GFS forecasts 26.5°C. Overlap is strong. 90% YES — invalid if significant cold frontal passage occurs.
Mexico City's climatological normals for May indicate an average high of 26.5°C, peaking before monsoon onset. Current synoptic patterns show stable high pressure aloft, suppressing convection and enhancing insolation. The potent urban heat island effect consistently adds 1-2°C to central station readings. With the 25°C threshold positioned below the typical mean, thermodynamic profiles strongly favor exceeding this mark. This is a clear undershot estimate. 95% YES — invalid if major cold front anomaly.
