Recent Met Office guidance and ensemble forecasts point to building high pressure over northwest Europe, promoting warm southerly flow and clear skies that support peak temperatures near 30–31°C in London on July 6. This setup favors strong daytime insolation and subsidence warming, though slight differences in the precise position of the ridge and any residual Atlantic moisture create spread across models, with some runs capping the maximum at 29°C and others briefly touching 32°C. Current trader positioning aligns closely with these central tendencies while assigning low probability to extremes, reflecting the inherent uncertainty in 48-hour convective details and boundary-layer mixing ahead of the next forecast cycle.
