Recent National Weather Service forecasts for Los Angeles point to persistent onshore flow and a marine layer stratocumulus deck that is expected to limit afternoon warming, positioning the 66-67°F bin as the leading outcome with 51% implied probability. Cool coastal sea surface temperatures sustain overnight cloud cover, delaying solar insolation and holding highs below the May climatological average of 69°F at official stations like KLAX. Model runs from GFS and ECMWF show modest spread in boundary-layer mixing depth, with lighter winds or drier aloft air potentially allowing earlier burn-off and a shift toward the 68-69°F range now at 33.5%. Traders are weighting these near-term atmospheric conditions over longer-term warming trends, as the marine influence typically dominates mid-May coastal readings. Overnight forecast revisions will refine the resolution criteria ahead of final observations.

The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the Los Angeles International Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/us/ca/los-angeles/KLAX.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C.
This market can not resolve to "Yes" until all data for this date has been finalized.
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.
Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.
