WEATHER NOTES SUMMARY BY HOURS

Wind Direction: Directions are those from which the wind is blowing, | | Averages | |
indicated in tens of degrees from true North: i.e., 09 for East, 18 for | +----+------+---+---+---+-----+Resultant|
South, 27 for West, and 00 or 36 for North. | | | | | | | | |
Wind Speed: The observed one-minute average speed in miles-per-hour. | | | | T | | | | Wind |
Wind Gust: The maximum instantaneous wind speed for the ten minute-period | | | | e | | % | W +----+----+
preceding the observation. | | | | m | D | | i | D | |
Rainfall Rate: The instantaneous rainfall rate at time of observation, | | S | P | p | e | H | n | i | |
calculated by timing consecutive 0.01" pulses from the electronic rain | | u | r | e | w | u | d | r | |
gauge and interpolating this rate for one hour. | | n | e | r | | m | | e | |

During a frozen precipitation event, hourly precipitation totals may not be recorded. In this case, daily amounts are
typically entered in the last column (hour ending at 12 A.M.)
