Trader sentiment clusters tightly around 14–17°C maxima for Paris on March 21, driven by ensemble forecasts from ECMWF and GFS models converging on mild conditions under a building high-pressure ridge over Western Europe, which favors southerly winds and above-average temperatures. Météo-France's latest runs project a peak near 15–16°C, aligning with the top market-implied odds, while slight divergences arise from GFS's warmer bias and potential overnight cloud cover suppressing extremes. Historical March 21 highs average 12°C but often exceed 15°C in similar ridging patterns; urban heat island effects in Paris could nudge readings higher, though incoming Atlantic moisture introduces 10–20% uncertainty in diurnal heating, keeping lower outcomes viable.
