Trader consensus on Polymarket prices a 40.5% implied probability for a high of 68-69°F at Los Angeles International Airport on May 15, driven by persistent marine layer stratus clouds and moderate onshore flow from the cool eastern Pacific, as detailed in the latest National Weather Service Los Angeles/Oxnard forecasts. Recent observations show highs in the mid-to-upper 60s over the past week—such as 66-67°F on May 12—reflecting classic "May Gray" conditions where low clouds trap heat near the surface, limiting daytime warming despite weak high pressure aloft. Model ensembles from NOAA indicate partial clearing possible midday, but with low confidence for exceeding 70°F, positioning 66-67°F (22.5%) and 70-71°F (19.5%) as close contenders. Watch for this afternoon's forecast update and evening model runs, which could refine land/sea breeze timing and cloud dissipation.
