Rules
This market will resolve to the temperature range that contains the lowest temperature reported at Chicago O'Hare Intl Airport (KORD) on 27 Oct '26.
- The qualifying value is the lowest temperature reported in the hourly temperature remark of any routine (METAR) observation for Chicago O'Hare Intl Airport (KORD) on that date, in tenths of a degree Celsius as reported.
- A report whose line begins with SPECI is a special observation and does not count.
- Every other report is routine, including one issued off the nominal hour and one that carries no METAR or SPECI label.
- 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
- The hourly temperature remark is the group beginning with the letter T followed by exactly eight digits.
