Trader consensus has converged on a daily high temperature of 90–91°F for Chicago on June 10, as confirmed by National Weather Service observations at official recording stations. This outcome reflects the influence of a warm air mass advecting northward under southerly flow, producing above-average readings across the Midwest during the period. With the calendar day complete and raw data collected, the market-implied probability now stands at essentially 100 percent for that narrow range. Only an unusual post-processing adjustment by the agency could alter the final value, though such revisions occur infrequently for well-monitored urban sites once preliminary reports are issued.
