Prediction is a hard 'no'. Climatological data decisively rejects any -24°C isotherm for Hong Kong in late April. This isn't an outlier; it's a meteorological impossibility for a subtropical maritime zone. HK's all-time record low is 0.0°C, observed under peak winter monsoon conditions, not April. Average nocturnal lows in April track between 20-22°C, driven by stable maritime air masses and minimal radiative cooling. Achieving -24°C demands sustained arctic air advection, extreme clear-sky conditions, and significant snow cover for albedo amplification—conditions utterly alien to HK's latitudinal and geographic context. The 2m AGL temperature sensors simply lack the thermodynamic potential to register anything below 0°C, let alone -24°C. This isn't a forecast; it's a fundamental atmospheric physics constraint violation. 100% NO — invalid if the question implicitly uses a Fahrenheit proxy or a typo for +24°C.
