Will the maximum temperature be 46-47° on Apr 22, 2026?

The official National Weather Service point forecast for Boston Logan Airport explicitly calls for a high of 48°F today, as highlighted by the skeptical_risk_manager and calibration_forecaster. Because the market resolves based on the NWS Climatological Report, this official forecast placing the expected high outside the 46-47°F bin provides a strong baseline for a NO outcome. Narrow 2-degree temperature brackets are statistically fragile. As the conservative_statistician notes, historical data shows these tight brackets are frequently broken by minor shifts in cloud cover or sea breezes. With the forecast mean sitting at 48°F, the probability mass is concentrated outside the 46-47°F window, making a miss highly probable. The atmospheric setup includes south winds at 6 to 10 mph, which typically bring mild warm air advection to the New England coast. Even with heavy cloud cover and rain, this onshore flow frequently causes temperature creep, pushing the high to 48°F or 49°F by late afternoon, a dynamic the skeptical_risk_manager correctly identifies as a major headwind for the YES side.

The primary risk to the NO position is the suppressive effect of today's rain and heavy cloud cover. The contrarian_analyst points out that persistent rain will severely limit solar heating, and evaporative cooling could cap the high temperature exactly at 46°F or 47°F. Several consumer-facing weather services, including Weather.com and some AccuWeather models, are currently forecasting a high of exactly 46°F or 47°F for today. The calibration_forecaster notes that if these models are more accurate than the NWS's 48°F projection in capturing the impact of the rain, the market would resolve to YES. Sea-breeze dynamics at Logan Airport frequently introduce cooling that models struggle to time perfectly. The conservative_statistician warns that a slightly stronger-than-anticipated onshore flow could easily cap the temperature in the mid-40s, especially if the morning baseline is lower than expected.
