Divergent short-range model ensembles from NOAA and ECMWF are fueling the tight trader consensus on Seattle's April 7 high temperature, with implied probabilities clustered around cooler bins like 53°F or below (29%) and 56-57°F (26.5%), nearly matching the outlier 72°F or higher (25.5%). Recent National Weather Service guidance shows partly sunny conditions with highs near 57°F through the weekend amid lingering marine clouds and light rain chances from a weakening trough, capping temperatures close to April climatological normals of 56-58°F. Warmer scenarios hinge on ridge amplification aloft, potentially yielding clear skies and downslope enhancement from the Cascades, though Puget Sound stratus often moderates extremes. New 12Z model runs and NWS updates expected today could sharpen the outlook amid typical day-4 uncertainty.
