Trader consensus on Polymarket closely splits probabilities across 64-69°F outcomes at 35.5% each, reflecting National Weather Service forecasts and model ensembles like GFS and ECMWF projecting a high near 66-68°F for downtown Los Angeles on May 4 amid persistent coastal marine layer. This low marine inversion layer, fueled by cool Pacific sea surface temperatures and moderate onshore flow (5-10 mph), traps stratus clouds through midday, capping solar heating and keeping highs below seasonal averages of 72-74°F seen in historical May 4 data. Differentiating factors include burn-off timing—delayed clearing under stronger winds favors 64-65°F, while earlier dissipation in lighter flow pushes toward 68-69°F—highlighting short-range uncertainty ahead of evening forecast updates.
