Traders' near-even split on 14-16°C highs for Madrid on March 21 stems from ensemble forecasts like ECMWF and GFS converging on a 15°C mean, amid a transitional Atlantic weather pattern bringing cooler northerly flows after milder early March conditions. AEMET's latest guidance points to 15-16°C maxima under partly cloudy skies and light winds, with diurnally driven variability creating the tight spread—lower 14°C odds reflect persistent cloud-induced suppression, while 16-18°C gains from potential clearer intervals boosting insolation. Historical March norms at 16°C provide baseline context, but recent cold air advection caps upside, heightening model divergence as key differentiator ahead of final runs.
