Trader consensus on Polymarket reflects tight uncertainty in National Weather Service forecasts for Chicago's highest temperature on April 6, with late-model runs from GFS and ECMWF ensembles clustering implied probabilities around 48-51°F amid persistent cloud cover from recent rounds of showers and thunderstorms through April 2-3. Cool mid-level temperatures aloft from a departing Canadian air mass limit diurnal heating, while southerly boundary-layer winds introduce variability—slight model differences in mixing and afternoon clearing could push peaks one bin higher or lower. Normal highs near 55°F are suppressed by overcast skies; watch NWS updates and 12Z model refreshes Friday for resolution shifts before the event.
