The Central Weather Administration's latest forecasts for Taipei project a daytime high range of 23–30°C on April 17 under partly clear skies with possible evening showers or thunderstorms, fueling trader consensus around 28–30°C with implied probabilities tightly clustered at 23–25.5% each for these outcomes, reflecting uncertainty in cloud cover extent and timing, which could limit solar insolation and cap peaks below 30°C or allow brief clearing to push toward 29–30°C amid light winds. April climatology averages 24–26°C highs, but recent days' spikes above 33°C have heightened expectations for urban heat at Songshan Airport station; watch intraday model updates and afternoon observations for shifts, as inherent short-term forecast divergence persists.
