Trader consensus on Polymarket prices a 65% implied probability for Chicago's highest temperature on April 2 reaching 48°F or higher, aligned with National Weather Service normals of 53.7°F for the date and NOAA's spring 2026 outlook favoring above-average warmth in the Midwest due to a developing upper-level ridge and transitioning ENSO-neutral conditions. Recent GFS and ECMWF ensemble runs from late March project highs in the upper 40s to mid-50s amid light southerly flow, though with low-confidence spread reflecting potential cold frontal passages. No major developments in the past 48 hours have shifted models significantly, but daily forecast updates from NWS Chicago and new model cycles through April 1 could adjust probabilities as resolution nears. Historical early April variability underscores uncertainty around cloud cover and timing of any precipitation.
