What counts as the highThe day's official high for the station, as The Weather Company publishes it for Kalshi (weather.com/kalshi) for events from Aug 14, 2026. It has matched the NWS climate report's official high on 1,587 of 1,588 settled days, and that high counts a peak between hourly reports.The highest reading in the "Temp" column of NOAA's time-series page for the station, using its hourly data, in whole degrees. A peak between two readings isn't in that column, so it can come out lower than the official high.
The dayMidnight to midnight local standard time, so 1 AM to 1 AM while clocks are on daylight time.Every time listed on that day on NOAA's page, which shows the station's local clock time.
The rangesTwo-degree brackets, with an open bracket at each end. Where the brackets start moves from day to day (61°–62° one day, 62°–63° another).Two-degree ranges that start on an even number (62°–63°), with an open range at each end.
