Trader consensus strongly favors a high of 64°F or higher in Seattle today, with 99.1% implied probability, aligning with the National Weather Service's latest forecast of mostly sunny skies and a peak near 70°F at Seattle-Tacoma International Airport. This positioning stems from a dominant high-pressure ridge over the Pacific Northwest, ushering in warm, dry continental air that has boosted recent highs—yesterday's models showed similar above-normal readings around 65–71°F. NOAA forecast ensembles exhibit tight agreement on robust diurnal heating from overnight lows near 50°F under clear conditions, well exceeding April climatological averages of 60–62°F. Realistic challenges include an unforeseen marine layer influx or persistent low clouds suppressing temperatures, though steering currents currently favor offshore flow; hourly observations through late afternoon will finalize resolution.
