- The qualifying value is the highest temperature reported in the hourly temperature remark of any routine (METAR) observation for Warsaw Chopin Airport (EPWA) on that date, in tenths of a degree Celsius as reported.

- For How to Read the METAR Report, see: https://polymarket-upload.s3.us-east-2.amazonaws.com/market_products/Weather/How+to+Read+the+METAR+Report.pdf
