Trader consensus on Polymarket centers around 70-71°F (34.5% implied probability) as Atlanta's highest temperature on April 6, driven by the National Weather Service's latest guidance showing a cold front arriving Sunday, cooling highs from recent mid-80s under high pressure (April 3-5 peaks near 81-83°F) back toward seasonal normals of 71°F. Ensemble forecasts from GFS and ECMWF models largely agree on post-frontal stabilization with partly cloudy skies and light northwest winds (5-10 mph), but uncertainty lingers in frontal timing—earlier passage could cap highs at 66-69°F via clouds and showers (24.5% odds), while delays allow more diurnal heating toward 72-75°F (25.6% combined). Key variables include boundary layer mixing, precipitation coverage (15-30% chance), and overnight cloud deck persistence; watch NWS updates at 6Z/12Z for refined model runs resolving the market before observation at Hartsfield-Jackson Airport.
