Fair Value Reasoning:

Synthesizing the latest forecasts from AccuWeather (59°F), Google/Weather.com (56°F), and Weather25 (57°F), temperatures in Seattle on March 20 will be driven by warm, moist air associated with an incoming Atmospheric River. While high precipitation chances (65-89%) typically limit diurnal heating, strong warm advection will maintain a mild baseline. Models strongly converge on the 56-57°F band, with AccuWeather's 59°F suggesting potential upside. Thus, 56-57°F holds the highest fair value, followed by 58-59°F and 54-55°F. The previously overpriced probability of extreme heat (62°F+) has been effectively ruled out by the rain forecast.

Movers

March 16, 2026 - March 17, 2026, the price of '62°F or higher' crashed from 26c to 8c, as NWS and commercial weather models confirmed a significant rainfall event (Atmospheric River) for March 20. The expected cloud cover and precipitation effectively eliminated the possibility of temperatures breaking 62°F, correcting the market's previous bias derived from the 2019 historical record. March 16, 2026 - March 17, 2026, the price of '58-59°F' dropped from 26.5c to 18.5c, as forecasts consolidated tightly around the 56-57°F median, reducing confidence in the upper-end temperature bands.
