Official observations from the National Weather Service's Automated Surface Observing System (ASOS) at Dallas Love Field confirm the highest temperature reached 62°F on April 21, 2026, aligning with trader consensus at nearly 100% implied probability for the 62-63°F bin and driving market resolution. This unusually cool reading—well below the April climatological average of 78°F—stemmed from a cold front's passage late on April 20, ushering in a stable, cool air mass under persistent overcast skies that suppressed daytime heating, as evidenced by METAR reports showing sustained low-level clouds and southeast winds. Minimal sunshine and lack of solar insolation prevented temperatures from climbing higher, consistent with forecast model consensus from NOAA. Realistic challenges to this positioning would require a rare post hoc data revision by NWS, such as sensor recalibration, though official records are highly reliable and finalizes market outcomes.
