Recent forecasts for Lucknow indicate overnight lows near 26–28°C on September 17 amid late-monsoon conditions, with scattered thunderstorms, high humidity above 80%, and variable cloud cover limiting radiative cooling. Persistent moisture from an active monsoon trough and potential overnight rain maintain elevated minimum temperatures by trapping heat and reducing clear-sky heat loss, while any clearer intervals or lighter winds could allow modest drops. Recent observations show minima running 1–2°C above normal, and model consensus points to similar patterns through mid-month before gradual monsoon withdrawal. This mix of thunderstorm timing, humidity levels, and cloud persistence creates genuine uncertainty across the 24–26°C range, supporting the closely matched market-implied probabilities. Updated IMD guidance and local model runs ahead of the date will refine these variables.

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.
