Recent forecast model runs for Warsaw show a tight cluster of maximum temperatures between 19–23°C on August 22, with ensemble guidance indicating possible thundery showers and increased cloud cover that could cap daytime heating. Surface pressure patterns and light westerly flow favor modest instability, while boundary-layer moisture and precipitation timing introduce uncertainty across European models. This spread explains the near-even market-implied odds across those five outcomes, as traders weigh the potential for 1–2°C differences driven by convective development versus clearer intervals. Historical August averages near 22–23°C provide context, but short-term variability in steering patterns keeps lower and higher thresholds at minimal implied probability ahead of the next model updates.
