Robust synoptic forcing from major GFS and ECMWF models indicates significant thermal advection over Guangzhou. All key meteorological outlets, including AccuWeather and Weather.com, project a high of 28°C for April 29, with lows around 21°C. This strong consensus places the daily maximum well above the 21°C threshold, confirming dominant zonal flow and warm airmass persistence. 99% YES — invalid if a major pattern shift introduces a cold air mass dropping highs below 21°C.
