The near-unanimous trader consensus at 100% for a Seattle high of 52-53°F on March 22 stems from the National Weather Service's latest short-range forecast, projecting a daytime maximum near 52°F amid partly cloudy skies and persistent onshore flow from the Pacific. Ensemble models like GFS and ECMWF converge on this mild outcome, aligning with Seattle's maritime climate where March highs typically average 54°F but are suppressed by cool marine layers this week. Recent soundings confirm stable low-level moisture capping warmth. Challenges could arise from unexpected ridging aloft or sudden clearing, allowing 5-8°F solar heating gains, though model spreads indicate under 1% likelihood for 54°F+.
