Trader consensus on Polymarket heavily favors a 12°C high in London on March 27 at 54.5% implied probability, driven by the latest Met Office forecast models showing a high-pressure ridge stabilizing over southern England, delivering mild southerly airflow with partial cloud cover capping daytime heating. Ensemble predictions from ECMWF and UKMO indicate peak temperatures clustering around 11–13°C, aligning with recent observations of similar setups yielding 11–12°C maxima earlier this week amid lingering Atlantic influences. Historical late-March averages for Heathrow (11.5°C) provide baseline support, though low-level jet streams introduce minor uncertainty for slight intensification. Traders await the 00Z model runs tomorrow for potential refinements ahead of the event.
