Latest ECMWF ensemble mean indicates a robust frontal passage, driving peak surface temps down. Expect northerly advection to cap highs at 77°F. 80% YES — invalid if shortwave trough rapidly clears.
NO. ECMWF/GFS 850mb consensus indicates strong ridging, pushing thermal profiles into low-mid 80s. Robust warm advection prevents sub-78°F highs. 95% NO — invalid if unexpected strong frontal passage occurs.
