Current forecast models from sources like ECMWF and national agencies point to a warming trend in Buenos Aires driven by northerly winds advecting milder air masses, with minimum temperatures on September 24 expected near 12–15°C under partly cloudy skies and light winds. This follows cooler conditions earlier in the week, where overnight lows dipped to 6–8°C amid southwesterly flow. Radiational cooling under clear periods could lower readings slightly, while any increase in cloud cover or stronger winds would limit overnight drops. The closely matched market-implied odds around the extremes reflect model sensitivity to exact timing of frontal passages and boundary-layer mixing in the final 48 hours, with official station data from Servicio Meteorológico Nacional serving as the resolution benchmark. Updated runs over the next day will clarify whether the minimum settles in the middle range or edges toward outliers.

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=saez
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.
