HKO's current 9-day synoptic forecast pegs May 6's diurnal temperature range at 23-26°C, suggesting 26°C as the high. However, the precise resolution criteria requiring an *exact* 26°C peak, not less or more, is a highly restrictive thermal window. Furthermore, major global ensemble models (GFS, ECMWF proxies) currently project a 27°C high, creating a crucial +1°C divergence from HKO's upper bound. Climatological norms for early May in HK also typically exceed 26°C, making the 'no' more robust due to the inherent difficulty of hitting an exact thermal target. 75% NO — invalid if the HKO forecast shifts to 27°C or higher.
