**A cold air advection event driven by strong southerly winds and a polar air mass shaped trader views on Buenos Aires’ September 12 minimum.** Pre-event forecasts from Argentine meteorological sources projected an overnight low near 4°C under persistent cloud cover, with winds averaging 27 km/h that enhanced sensible cooling and reduced the chance of strong radiational drops. Official model consensus and historical September climatology (typical overnight lows 8–12°C) supported a narrow 4–6°C range, producing the tight market split between 6°C (51%), 5°C (49%), and 4°C-or-below (50%). Post-frontal clearing on the 13th and observed readings near 5°C (41°F) at representative stations further validated the narrow uncertainty band, with resolution hinging on the precise official minimum recorded at the primary synoptic site.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Minister Pistarini Intl Airport Station in degrees Celsius on 12 Sep '26.
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.**A cold air advection event driven by strong southerly winds and a polar air mass shaped trader views on Buenos Aires’ September 12 minimum.** Pre-event forecasts from Argentine meteorological sources projected an overnight low near 4°C under persistent cloud cover, with winds averaging 27 km/h that enhanced sensible cooling and reduced the chance of strong radiational drops.
