Low so far set at 6:52 AM. Same station and day as the high; closes in 17 h 47 min.
From KDCA's NWS climate reports (via the Iowa Environmental Mesonet) and Kalshi's settlements and stored prices. Facts about past days, not forecasts.
Live prices in all 24 cities (these are 30 minutes late), 12 weather models' forecasts for this station (KDCA) on the chart and in a table, whether today is running hotter or cooler than they expected, and how each model has done here.
Model record: in our test the market's prices were more accurate than the model (log loss 1.26 vs 1.48 a day ahead, 0.92 vs 1.25 on the day; lower is better).
Every report from the station today (a ), in exact whole °F. “6 h max” is the station's own highest reading over the past 6 hours, which can catch a peak between hourly reports.
