This station reports both the quantity of liquid precipitation and categorical observations of precipitation (e.g., moderate rain, or heavy snow). Both are subject to erroneous reports, but the former is particularly prone to false reports, especially ones indicating an excessive quantity of precipitation. Please bear this in mind when reading the extrema reported in this section.
The day with the largest quantity of precipitation was August 27. That day saw 6.551" of liquid (or liquid equivalent) precipitation, compared to a median value of 0.132". The month with the most precipitation was August, with 11.532", compared to a median value of 6.846".
As determined by quantitative measurements, the longest dry spell was from January 1 to February 5, constituting 36 consecutive days with no measured precipitation. The month January were completely without measured precipitation.
The month with the largest fraction of days with at least some measured precipitation was August, with 58% of days reporting some measured precipitation.
This station reports when significant weather events (including precipitation) are visually observed at or near the station. Such events do not always correspond to measured quantities of liquid equivalent precipitation, such as when the event is near by not at the station, or in the case of solid precipitation that does not melt in the collection basin.
The day in 2012 with the most precipitation observations was August 27. There were 20 hourly weather reports that day (out of a maximum of 24) in which some form of precipitation was observated at or near the station. The month with the most precipitation observations was August, with 128 hourly present weather reports involving some form of precipitation.
As determined by the present weather reports, the longest dry spell was from January 1 to February 5, constituting 36 consecutive days with no observed precipitation. The month January was completely without observed precipitation.
The month with the largest fraction of days with at least some observed precipitation was August, with 71% of days reporting some observed precipitation.
Either snow is exceptionally rare at this location or this station did not reliably report it during 2012.
Humidity is an important factor in determining how weather conditions feel to a person experiencing them. Hot and humid days feel even hotter than hot and dry days because the high level of water content in humid air discourages the evaporation of sweat from a person's skin.
When reading the graph below, keep in mind that the hottest part of the day tends to be the least humid, so the daily low (brown) traces are more relevant for understanding daytime comfort than the daily high (blue) traces, which typically occur during the night. Applying that observation, the least humid month of 2012 was April with an average daily low humidity of 45%, and the most humid month was September with an average daily low humidity of 61%.
But it is important to keep in mind that humidity does not tell the whole picture and the dew point is often a better measure of how comfortable a person will find a given set of weather conditions. Please see the next section for continued discussion of this point.
Dew point is the temperature below which water vapor will condense into liquid water. It is therefore also related to the rate of evaporation of liquid water. Since the evaporation of sweat is an important cooling mechanism for the human body, the dew point is an important measurement for understanding how dry, comfortable, or humid a given set of weather conditions will feel.
Generally speaking, dew points below 50°F will feel a bit dry to some people, but comfortable to people accustomed to dry conditions; dew points from 50°F to 68°F are fairly comfortable to most people, and dew points above 68°F are increasingly uncomfortable, becoming oppressive around 77°F.
To take some examples, and basing our categorization on the daily high dew point in 2012, January had 5 dry days, 25 comfortable days, and 1 humid day; April had 1 dry day, 18 comfortable days, and 11 humid days; July had no dry days, no comfortable days, and 31 humid days; and October had 1 dry day, 7 comfortable days, and 23 humid days.
The highest sustained wind speed was 30 mph, occurring on October 26; the highest daily mean wind speed was 21 mph (October 26); and the highest wind gust speed was 53 mph (May 7).
The windiest month was March, with an average wind speed of 9 mph. The least windy month was September, with an average wind speed of 6 mph.
Visibility is the maximum distance at which a given reference object or light can be clearly discerned. In the United States, visibilities that are greater than or equal to 10 miles are typically reported as 10 miles.
The day of 2012 with the lowest average visibility was August 27, with an average visibility of 6.8 mi. The month with the lowest average visibility was December, with an average visibility of 9.4 mi. With an average visibility of 9.9 mi, the month of April had the highest average visibility.
The cloud ceiling is the altitude of the lowest layer of clouds that are at categorized as broken (mostly cloudy) or overcast (cloudy). If no such cloud layer exists then the ceiling is unlimited and no value is reported.
The day of 2012 with the lowest average cloud ceiling was September 23, with an average cloud ceiling of 100'. The month with the lowest average cloud ceiling was December, with an average cloud ceiling of 4469'. The month of June has the highest average cloud ceiling, with an average cloud ceiling of 5844'.
