Cloud Cover Categories in December
A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. In High Level, the chance of a wet day over the course of December is gradually decreasing, starting the month at 13% and ending it at 11%.
For reference, the year's highest daily chance of a wet day is 28% on July 4, and its lowest chance is 10% on February 18.
Probability of Precipitation in December
We report snowfall in liquid-equivalent terms. The actual depth of new snowfall is typically between 5 and 10 times the liquid-equivalent amount, assuming the ground is frozen. As with rainfall, we consider the liquid-equivalent snowfall accumulated over a sliding 31-day period centered around each day.
The average sliding 31-day liquid-equivalent snowfall during December in High Level is essentially constant, remaining about 0.5 inches throughout, and rarely exceeding 1.2 inches or falling below 0.1 inches.
Average Monthly Liquid-Equivalent Snowfall in December
Over the course of December in High Level, the length of the day is gradually decreasing. From the start to the end of the month, the length of the day decreases by 22 minutes, implying an average daily decrease of 45 seconds, and weekly decrease of 5 minutes, 12 seconds.
The shortest day of the month is December 21, with 6 hours, 19 minutes of daylight and the longest day is December 1, with 6 hours, 49 minutes of daylight.
Hours of Daylight and Twilight in December
The earliest sunrise of the month in High Level is 9:12 AM on December 1 and the latest sunrise is 26 minutes later at 9:38 AM on December 27.
The earliest sunset is 3:54 PM on December 15 and the latest sunset is 11 minutes later at 4:05 PM on December 31.
Daylight saving time is observed in High Level during 2017, but it neither starts nor ends during December, so the entire month is in standard time.
For reference, on June 21, the longest day of the year, the Sun rises at 4:40 AM and sets 18 hours, 21 minutes later, at 11:00 PM, while on December 21, the shortest day of the year, it rises at 9:37 AM and sets 6 hours, 19 minutes later, at 3:56 PM.
Sunrise & Sunset with Twilight and Daylight Saving Time in December
We base the humidity comfort level on the dew point, as it determines whether perspiration will evaporate from the skin, thereby cooling the body. Lower dew points feel drier and higher dew points feel more humid. Unlike temperature, which typically varies significantly between night and day, dew point tends to change more slowly, so while the temperature may drop at night, a muggy day is typically followed by a muggy night.
The chance that a given day will be muggy in High Level is essentially constant during December, remaining around 0% throughout.
For reference, on July 26, the muggiest day of the year, there are muggy conditions 0% of the time, while on September 15, the least muggy day of the year, there are muggy conditions 0% of the time.

This section discusses the wide-area hourly average wind vector (speed and direction) at 10 meters above the ground. The wind experienced at any given location is highly dependent on local topography and other factors, and instantaneous wind speed and direction vary more widely than hourly averages.
The average hourly wind speed in High Level is essentially constant during December, remaining within 0.1 miles per hour of 4.4 miles per hour throughout.
For reference, on January 30, the windiest day of the year, the daily average wind speed is 4.8 miles per hour, while on July 21, the calmest day of the year, the daily average wind speed is 3.3 miles per hour.

This section discusses the total daily incident shortwave solar energy reaching the surface of the ground over a wide area, taking full account of seasonal variations in the length of the day, the elevation of the Sun above the horizon, and absorption by clouds and other atmospheric constituents. Shortwave radiation includes visible light and ultraviolet radiation.
The average daily incident shortwave solar energy in High Level is essentially constant during December, remaining within 0.1 kWh of 0.3 kWh throughout.
The lowest average daily incident shortwave solar energy during December is 0.3 kWh on December 21.

Temperature and Dew Point
There is only a single weather station, High Level Airport, in our network suitable to be used as a proxy for the historical temperature and dew point records of High Level.
At a distance of 12 kilometers from High Level, closer than our threshold of 150 kilometers, this station is deemed sufficiently nearby to be relied upon as our primary source for temperature and dew point records.
The station records are corrected for the elevation difference between the station and High Level according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations.
Please note that the station records themselves may additionally have been back-filled using other nearby stations or the MERRA-2 reanalysis.
All data relating to the Sun's position (e.g., sunrise and sunset) are computed using astronomical formulas from the book, Astronomical Tables of the Sun, Moon and Planets , by Jean Meeus.
All other weather data, including cloud cover, precipitation, wind speed and direction, and solar flux, come from NASA's MERRA-2 Modern-Era Retrospective Analysis . This reanalysis combines a variety of wide-area measurements in a state-of-the-art global meteorological model to reconstruct the hourly history of weather throughout the world on a 50-kilometer grid.
Land Use data comes from the Global Land Cover SHARE database , published by the Food and Agriculture Organization of the United Nations.
Elevation data comes from the Shuttle Radar Topography Mission (SRTM) , published by NASA's Jet Propulsion Laboratory.
Names, locations, and time zones of places and some airports come from the GeoNames Geographical Database .

We draw particular cautious attention to our reliance on the MERRA-2 model-based reconstructions for a number of important data series. While having the tremendous advantages of temporal and spatial completeness, these reconstructions: (1) are based on computer models that may have model-based errors, (2) are coarsely sampled on a 50 km grid and are therefore unable to reconstruct the local variations of many microclimates, and (3) have particular difficulty with the weather in some coastal areas, especially small islands.
