PAGE NOTES:

  1. Graphs along with daily and monthly tables are updated every 5 minutes. Yearly tables are updated at the top of every hour.
  2. "NWS" averages are the sum of the daily high temperature & daily low temperature divided by 2. This is the National Weather Service method used for climatological summaries. All other fields labelled "avg" contain integrated averages using one minute samples.
  3. "Wind Dir" is a scalar average of direction irrespective of speed. However, calm winds do not have a valid direction and are not included in the average.
  4. "Wind Run" uses the 10 minute wind average.
  5. "Low 10 Min Avg" & "Low Max" wind values are omitted from yearly summary table since every field equals 0.
  6. In the daily and monthly summaries, "Wind Chill" appears only October through April. It is calculated when the temperature is 45 or below and average wind speed is at least 3 mph. Otherwise, it equals the temperature. Likewise, "Heat Index" appears only May through September. It is calculated only when the temperature is 80 or above. Otherwise, it equals the temperature.
  7. "Liquid" precipitation in the winter is the amount of melted snow and/or ice.
  8. Snow measurement began in October 2017.
  9. Since January 15, 2018, pressure is recorded in altimeter format. The home page, however, continues to display "Barometer" in MSLP formulation by default.
