Recent forecasts from Argentina’s Servicio Meteorológico Nacional and global models show a strong southerly flow and high pressure (around 1034 hPa) advecting cold air into the region, with clear skies promoting radiational cooling overnight. Official guidance points to an early-morning minimum near 3 °C, though several numerical runs and station observations indicate localized readings dipping to 0–2 °C under light winds and low dew points. This supports the market’s heavy weighting toward 0 °C and –1 °C as the most probable recorded low for September 6. Warmer advection begins midday, limiting further drops, while wind-chill values near –2 °C have no bearing on the official dry-bulb measurement used for resolution. Updated model runs and the 9 a.m. local observation will provide the final confirmation.

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.
