**Market-implied odds reflect substantial uncertainty in the overnight minimum temperature for Buenos Aires on September 17.** Current forecasts from multiple models project lows of roughly 10–14 °C under clear to partly cloudy skies, with light northerly or northeasterly winds and high pressure supporting gradual warming after recent cooler conditions. Spring variability in the region allows for potential cold-air advection from the south or stronger radiational cooling under calm winds that could push readings toward single digits, while any delay in the nocturnal temperature drop or warmer boundary-layer air could keep the minimum above 15 °C. Model spreads in boundary-layer mixing and dew-point forecasts create the balanced 40 % probabilities on the extreme tails, with finer bins clustered around 8–11 °C capturing the central tendency. Updated runs overnight and early-morning observations will likely narrow the range 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.
