Persistent high pressure over the Hudson Bay region is sustaining northerly flow and cooler-than-normal air across the Midwest, driving the market's concentration around 68–73°F for Chicago's June 26 high despite a climatological normal near 83°F. Recent NOAA and NWS model runs show limited diurnal mixing and potential afternoon cloud cover or weak frontal passages that cap daytime maxima in the low to mid-70s, aligning with the heaviest trading in the 70–71°F bin at 26.5%. Key variables include ridge strength and position, steering pattern shifts that could briefly enhance warming, and any timing changes in boundary passage. With 48-hour forecast uncertainty remaining, traders assign lower probabilities to extremes while awaiting updated short-range guidance.
