**Trader sentiment centers on current atmospheric conditions in Panama City, Panama, where the rainy season maintains high humidity and frequent convective activity that limit overnight radiative cooling.** Forecasts from regional models indicate overnight lows near 24–26°C, with the tight clustering around 25–26°C reflecting uncertainty in cloud cover and precipitation timing on September 22. Elevated dew points near 24–25°C reduce the temperature drop after sunset by suppressing longwave radiation loss, while light variable winds (under 10 km/h) provide minimal mixing. Thunderstorm outflows or lingering cloud decks from daytime convection can trap heat and push the minimum toward 26°C, whereas clearer intervals allow modest cooling to 25°C or slightly below. Historical September averages of 24°C lows provide context, but short-term variability in the Intertropical Convergence Zone position and moisture influx keeps probabilities balanced among the leading outcomes without strong divergence in model guidance.

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=mpmg
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.
