Trader sentiment for Seattle's March 23 high temperature hinges on NOAA ensemble models implying a peak near 51°F, with 50-51°F (29.5%) edging 52-53°F (27.0%) due to persistent marine stratus limiting diurnal heating. Cool Pacific air advection and a weak high-pressure ridge foster cloud cover, capping highs below seasonal norms of 55°F; GFS 12z runs forecast 50-52°F maxima, while ECMWF shows minor spread toward 52°F on potential afternoon clearing. Recent overnight updates stabilized odds by confirming low-level inversion strength, differentiating bins by slim 1-2°F margins amid 70% probability of overcast skies. Key watch: NWS 18z forecast for resolution triggers.
