Trader consensus on Polymarket reflects tight uncertainty in Buenos Aires' highest temperature today, with 23°C leading at 33.5% implied probability amid forecasts from sources like timeanddate.com and local models projecting a midday peak of 23°C under overcast skies and passing showers. A developing cyclogenesis over the past 48 hours has introduced persistent low cloud cover, southerly winds up to 23 km/h, and light precipitation (0.1-0.3 mm/hour), suppressing solar insolation and promoting evaporative cooling to cap highs at 22-24°C versus April climatological averages near 23°C. Differentiation hinges on afternoon cloud breaks potentially boosting 24°C odds or heavier showers favoring 22°C; hourly observations from Aeroparque or Ezeiza stations through late afternoon will clarify resolution amid inherent short-term forecast divergence.
