Latest National Weather Service forecasts project a minimum temperature near 68°F on September 23 under clear skies and light winds, supporting the market's tight clustering around mid-60s outcomes. Diurnal temperature ranges in Los Angeles during late September typically allow for 15-20°F drops from afternoon highs in the mid-80s, influenced by the urban heat island effect and proximity to the Pacific. Any marine layer intrusion or wind shifts could alter overnight cooling rates, though current model consensus favors minimal cloud cover. Updated forecasts expected from NWS as the date approaches.

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=klax
This market will resolve off of the Hourly Data provided using the "Show Hourly Data" button.
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 US Units w/ kts" button until the relevant table displays °F.
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 Fahrenheit (eg, 21°F). 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.
