Recent forecasts from the India Meteorological Department and international models, including the Met Office, indicate a minimum temperature near 26°C overnight into September 19 in Lucknow, supported by persistent cloud cover, high humidity near 70-80%, and light variable winds that limit radiative cooling under typical late-monsoon conditions. These factors position the 26°C outcome as the market leader at 47.5% implied probability, while elevated chances for 30°C or higher reflect uncertainty around daytime heat retention or clearer breaks. The 20°C or below option at 27.5% remains a longer shot given climatological baselines and current steering patterns that favor stable warmth. Updated model runs and official briefings expected tomorrow morning will refine resolution criteria for the daily low.

The resolution source for this market will be information from NOAA, specifically the lowest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=vilk
If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
