Trader sentiment favors 88°F or higher in Los Angeles on March 25 at 37.5% implied probability, propelled by the latest GFS and ECMWF ensemble forecasts showing a robust upper-level ridge over the Southwest, promoting adiabatic warming and offshore Santa Ana winds that erode the coastal marine layer. National Weather Service outlooks align with highs in the low-to-mid 80s under clear skies and low humidity, well above the March climatological average of 68°F. Divergent model runs introduce uncertainty, with 25.5% odds on 69°F or below if onshore flow strengthens, while mid-70s bins like 74-75°F cluster around 17% reflecting baseline variability. Watch 00Z model updates for wind shear refinements that could pivot probabilities.
