Taipei's climatological May averages consistently show daily highs near 29°C. Current NWM ensemble guidance (GFS, ECMWF) for May 5 robustly projects daytime max temps into the mid-20s, driven by a persistent warm advection pattern. A dominant upper-level ridge will prevent any cold air intrusions, and optimal boundary layer dynamics ensure significant radiative forcing. 18°C is an extreme statistical outlier, totally detached from observed norms and predictive models. 95% YES — invalid if an unprecedented, anomalous polar vortex disruption reaches Taiwan.
