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.
