Trader consensus on Polymarket narrowly favors a Seattle high of 46-47°F at 30.1% implied probability over 48-49°F at 28.0%, driven by the National Weather Service's latest guidance projecting upper 40s to near 50°F on March 29 under a developing upper-level ridge over the Pacific Northwest. Cool Puget Sound sea surface temperatures near 48°F cap daytime heating by stabilizing the marine boundary layer, while light northerly winds and potential lingering morning stratus clouds versus afternoon clearing create the tight split between bins. Recent highs reached 56-58°F mid-week amid transient ridging, but models now converge on subdued insolation with minimal disagreement in ensemble means around 47-48°F. Watch NWS Seattle's evening forecast discussion and 00Z model runs for updates on cloud trends ahead of resolution at KSEA.
