March 21, 2026 (09:40 - 17:15), the price of '18°C' crashed from 27.5c to 7.5c, while '20°C' surged from 33.5c to 44.5c. The reason is that intraday weather model updates (likely 12z data) on the 21st contradicted earlier cold forecasts, confirming a warmer trend. March 19 - March 20, 2026, the price of '22°C' dropped from 19c to 7.5c as early models ruled out high heat (>22°C) approaching the date, compressing expectations into the lower-mid temperature range.

Significant divergence exists. Previous official forecasts (IMS) indicated a high of only 16°C, and the market priced 18°C highly until the morning of March 21. However, the sudden price shift on the afternoon of March 21 suggests that the latest real-time meteorological data has severely deviated from the older official forecast (16°C). The market is aggressively repricing based on a newer warming trend rather than adhering to outdated official guidance.

March 22, 2026 - March 23, 2026, the price of '76-77°F' surged from 5.5c to 22.2c, as meteorological models closer to Monday showed intensified cold front effects, triggering panic buying of cooler ranges. March 22, 2026, the price of '84°F or higher' crashed from 32.5c to 3c (rebounding slightly to 5c), as Sunday's live forecasts completely ruled out the possibility of extreme heat on Monday. March 22, 2026, the price of '80-81°F' briefly spiked to 34.5c before pulling back, indicating market hesitation to fully embrace this range as the 'new favorite,' with capital diverting towards 78-79°F and 76-77°F.

Significant market divergence exists. Although the resolution source Wunderground previously forecast 78°F, the market currently prices '80-81°F' as the top favorite (~29.5c) instead of the source-aligned '78-79°F' (~23.2c). This suggests the market is lagging in reacting to the speed of the cooling trend or is still anchored to outdated, warmer AccuWeather forecasts.

While generic algorithmic models (e.g., Google/TWC) forecast a high of 75°F, biasing the market towa...

2026-03-21 11:50 - 17:15, the price of '78-79°F' saw high volatility, crashing from ~23c to 9.5c before rebounding to 21c; simultaneously, '76-77°F' spiked to 33c. This was likely driven by an intraday model run suggesting an earlier cold front passage (cooling bias), which was later corrected by authoritative updates (like NWS confirming heat remains for Monday), causing capital to flow back into warmer ranges. 2026-03-19, the price of '84°F or higher' collapsed from 25.5c to single digits as forecast horizons narrowed, ruling out extreme heat scenarios.

Significant divergence exists. The market currently favors the 76-77°F range (~35%), aligning closely with generic weather app forecasts (e.g., Apple Weather/The Weather Channel at 75°F). However, professional meteorological sources (NWS Atlanta) and local media (WXIA, Fox5) are distinctly warmer, forecasting 78°F to low 80s. The market is over-indexing on generic algorithmic data while ignoring expert adjustments for pre-frontal heating and local heat island effects.

According to the latest Google Weather forecast (sourced from The Weather Channel, parent of Wunderg...

There is a distinct contradiction in the rules. The resolution source link points to the Wunderground 'History' page, which displays actual observations. However, the rule text states 'recorded... by the Forecast', which is terminologically conflicting (History/Actuals vs Forecast). This is likely a copy-paste error intending to mean 'recorded by the Station', but a literal interpretation could cause disputes. Additionally, reliance on a single specific station (LTAC) carries risks of data gaps or temporary outages on the specific platform.

From March 21 to March 23, 2026, the price of 12°C plummeted from 35.5c to 16.5c, while 11°C surged from 19c to 42.5c (before settling at 35.5c). The reason is that as the event date approached, weather models converged, ruling out warmer air masses (12°C+), forcing a violent market correction towards the cooler range (10-11°C). Notably, 9°C has also started to bid up from the bottom (4c to 9c), reflecting the latest rainy/cooler forecasts.

Significant divergence exists. The market prices 11°C as the favorite (35.5%), followed by 10°C. However, the specific forecast for the airport location (Çubuk) from the resolution source's parent company (The Weather Channel/Google) is 9°C. The market appears anchored to AccuWeather's higher forecast (10.5°C) or Ankara city center temperatures (typically warmer), ignoring the resolution-source-specific microclimate data (rain/9°C).

Core Reasoning: Meteorological data strongly supports '51°F or below'. The latest NWS discussion (is...

2026-03-22 14:55 - 2026-03-22 18:10, the price of '51°F or below' surged from 37c to 59.5c. The reason was that as Sunday progressed, short-range models and real-time radar reassured traders that the cold front would pass on time, reducing panic about a 'midnight high' and causing prices to revert toward meteorological fundamentals. 2026-03-22 10:35 - 2026-03-22 14:55, the price of '51°F or below' dropped from 48.5c to 37c, due to brief market panic that the cold front might be delayed, causing capital to hedge into the '52-53°F' option.

Significant divergence exists. Mainstream weather forecasts (Google, AccuWeather, Weather.com) consistently predict a high of 43-44°F for NYC on March 23, falling squarely within the '51°F or below' range. However, Polymarket prices imply only a ~56% probability for this option. This divergence stems from prediction market participants over-hedging against a 'Midnight High' (temps at 00:00-01:00 AM exceeding daytime highs), ignoring the latest NWS guidance that the cold front will clear before midnight.
