Trader consensus on Polymarket reflects the latest National Weather Service forecast models projecting Seattle-Tacoma International Airport highs of 68-71°F on April 6, fueled by a developing upper-level ridge ushering in clear skies and subsidence warming after rainy systems capped recent highs in the mid-50s through April 4. The tight race between 68-69°F (42.5% implied probability) and 70-71°F (35.5%) stems from model disagreements on morning marine stratus burn-off timing and peak afternoon boundary-layer mixing, with GFS leaning slightly warmer than ECMWF ensembles. NOAA's April outlook favors above-normal temperatures amid persistent ridging over the Pacific Northwest. Watch 12Z and 18Z model runs today for potential shifts ahead of resolution.
