NOAA, National Centers for Environmental Information PAGE Note : The hourly and daily precipitation totals are printed in the last 2 columns and hi-lighted in red when they disagree. NWS does not edit ASOS hourly values but may edit daily and monthly totals. Hourly, daily, and monthly totals are printed as reported by the ASOS site.

3 REFERENCE NOTES & SUPPLEMENTAL SUMMARIES * = Extreme for the month (last occurence if more than one). T = Trace precipitation amount. + = also occurs on earlier date. FG+ = Heavy fog, visibility.25 miles or less. BLANK entries denote missing or unreported data. Resultant wind is the vector sum of the wind speeds and directions divided by the number of observations. Wind direction is recorded in tens of degrees (2 digits) clockwise from true north. '00' = calm, 'VR' = variable. Precipitation is for the 24-hour period ending at the time indicated in the column heading. Ceilometer (30-second) data are used to derive cloudiness at or below 12,000 feet. This cloudiness is the mean cloud cover detected during sunrise to sunset (SR-SS), or midnight to midnight (MN-MN).

Clear = 0-2 oktas, Partly Cloudy = 3-6 oktas, Cloudy = 7-8 oktas. A Heating (Cooling) Degree Day is the difference between the average daily temperature and 65 degrees F. The HDD season begins July 1, the CDD season begins January 1. Snow Depth, Snowfall, and Sunshine data may come from nearby sites that the National Weather Service deems Climatologically representative of this site.
