National Weather Service guidance issued early March 28 forecasts a high near 55°F at Seattle-Tacoma International Airport under partly sunny skies with high clouds in westerly upper-level flow, driving the tight trader split between 54-55°F (39.5% implied probability) and 56-57°F (41.5%). Morning observations show temperatures in the low 40s°F amid light winds, with peak heating potential around 2-4 PM PDT if Puget Sound marine stratus burns off fully; however, embedded cirrus and possible low-level moisture may limit warming to the mid-50s, per GFS and ECMWF ensemble means clustering near 55°F. This neutral setup aligns with March climatology (average high 54°F), but intraday cloud variability creates the razor-thin differentiation—watch HRRR refreshes and airport ASOS data for resolution cues.
