**Strong southwesterly winds following Sunday's storms are driving cooler air into the region, with models pointing to a minimum near or below 8°C overnight.** Clearing skies after earlier rain allow for enhanced radiational cooling under light winds later in the night, while the post-frontal airmass and gusty flow (often 30-60+ km/h) keep daytime highs modest around 16-17°C. Official Servicio Meteorológico Nacional guidance has cited minima closer to 12-13°C, but international numerical weather prediction runs (including those underlying many forecast services) consistently show overnight lows of 7-10°C, creating the observed market skew. The 50% implied probability on 7°C or below reflects trader emphasis on these cooler model solutions and the potential for the daily minimum to fall at the lower end of the envelope, with 8-11°C outcomes capturing residual uncertainty in exact timing and boundary-layer mixing. Updated model runs and official observations through the night will be key resolution inputs.

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.
