Beijing's climatological normals for late April pinpoint mean daily highs around 20-23°C. The 22°C mark aligns precisely with the expected seasonal thermal progression, indicating no major synoptic anomalies are forecasted. Extended range models (GFS/ECMWF analog consensus) show no significant cold advection or anomalous warm airmass build-up. Isothermal analysis confirms stable thermal gradients. This is a high-probability event, squarely within the standard diurnal range. 95% YES — invalid if a strong polar vortex lobe or Saharan dust plume affects the region.
