Recent National Weather Service forecasts and model consensus for Los Angeles International Airport indicate an overnight low in the mid-60s Fahrenheit on September 22, driven by clear skies, light westerly winds, and typical late-summer marine layer moderation along the coast. This positions the 66-67°F range as the market leader at 75% implied probability, with adjacent bins like 64-65°F reflecting residual uncertainty in exact minimum readings from official hourly data. Historical September climatology at LAX shows average lows near 65°F, and absent any incoming frontal systems or heat anomalies, the current atmospheric setup favors this narrow band over lower thresholds that would require unusual radiative cooling or higher ones inconsistent with observed dew points around 60°F. Updated NWS guidance tonight and early tomorrow will provide the final resolution data.

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.
