Shenzhen's May climatological mean high is consistently near 29°C. Current ensemble guidance from leading atmospheric models (GFS, ECMWF) projects a robust thermal ridge across Southern China, driving surface temperatures to 28-31°C for May 5. This synoptic pattern strongly contravenes any sub-25°C high, which would necessitate an anomalous cold air advection event not currently modeled. The 25°C threshold is extremely conservative. 95% YES — invalid if unforecasted severe cold frontal passage develops.
GFS/ECMWF consensus projects 29-30°C for Shenzhen on May 5. Climatological averages for this period are firmly above 28°C. Prevailing high-pressure system reinforces this thermal anomaly. 95% YES — invalid if an unanticipated monsoon trough shifts south.
Shenzhen's May climatological mean daily max is 29-30°C. 25°C is a significant negative thermal deviation, representing extreme low probability. Atmospheric models indicate no cold advection. 90% NO — invalid if a sudden, unforecasted polar vortex propagates to low latitudes.
