Fair Value Reasoning:

Latest meteorological consensus (NWS, AccuWeather, KING5) explicitly targets a high of 58°F for Seattle on March 19. While Google/The Weather Channel still shows 56°F with rain (which typically suppresses heating), the NWS guidance of 'High near 58' is a strong anchor. The market currently prices 56-57°F as the favorite (27c), while pricing the more data-supported 58-59°F lower (22.5c). While rain justifies keeping 56-57°F competitive, 58-59°F is currently undervalued and represents the highest fair value bracket.

Movers

March 16, 2026 - March 17, 2026, the price of '58-59°F' saw significant volatility, surging to 31c on updated NWS forecasts before correcting down to 21c, as the market weighed the cooling effects of persistent rain against model highs. March 15, 2026 - March 16, 2026, the price of '62°F or higher' crashed from 26.5c to 12.5c as near-term models confirmed incoming rain bands, effectively eliminating the chance of anomalous heat. March 15, 2026 - March 16, 2026, the price of '54-55°F' dropped from 25.5c to 14c before rebounding on the 17th, reflecting the market's tug-of-war between the '58°F model forecast' and the 'rain suppression' thesis.

Divergence

Significant divergence exists. Major meteorological agencies (National Weather Service, AccuWeather, Local KING5) all forecast a high of 58°F, directly aligning with the '58-59°F' option. However, the prediction market currently favors '56-57°F' (27c) over '58-59°F' (22.5c). This suggests traders are either leaning towards The Weather Channel's lower forecast (56°F) or over-hedging against rain-induced cooling, creating a mispricing where 58-59°F is undervalued relative to the consensus data.
