Current forecasts from agencies including Argentina’s Servicio Meteorológico Nacional point to a daily minimum near 11–12 °C on 24 September, driven by northerly advection of warmer, moister air following the polar outbreak that produced 5–7 °C lows earlier in the week. Model consensus shows light northerly winds, mostly clear to partly cloudy skies, and dew points rising into the 8–10 °C range, limiting radiational cooling. This places the most probable outcome in the 11–13 °C band, consistent with climatological spring warming trends after early-season cold fronts. Trader positioning remains nearly even between sub-8 °C and 17 °C+ bins, reflecting residual uncertainty in overnight boundary-layer mixing and any last-minute model shifts before resolution.

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.
