Latest guidance from major forecast models, including those reflected in Accuweather and international ensembles, positions Paris's highest temperature today at around 11°C with 79.5% market-implied probability, due to persistent mostly cloudy skies, morning showers, and thundershowers under a yellow warning that suppress diurnal heating. A cool maritime air mass from the Atlantic, combined with moderate westerly winds, has limited solar insolation and surface warming, keeping peaks below the May climatological average of 19°C. Morning observations confirmed subdued early highs around 10°C, prompting traders to adjust odds downward from prior 12°C favoritism; remaining hours feature ongoing precipitation risks, though brief clearing could nudge toward 12°C (22.5%). Official Météo-France measurements at central stations will resolve the market by midnight.
