Sunrise & Sunset with Twilight and Daylight Saving Time
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.
Fort Leonard Wood experiences extreme seasonal variation in the perceived humidity.
The muggier period of the year lasts for 4.2 months, from May 17 to September 25, during which time the comfort level is muggy, oppressive, or miserable at least 18% of the time. The muggiest day of the year is July 22, with muggy conditions 73% of the time.
The least muggy day of the year is January 15, when muggy conditions are essentially unheard of.

This report illustrates the typical weather in Fort Leonard Wood, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016.
Temperature and Dew Point
There are 3 weather stations near enough to contribute to our estimation of the temperature and dew point in Fort Leonard Wood.
For each station, the records are corrected for the elevation difference between that station and Fort Leonard Wood according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations.
The estimated value at Fort Leonard Wood is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Fort Leonard Wood and a given station.
The stations contributing to this reconstruction are: Waynesville-St. Robert Regional Airport (98%, 5.0 kilometers, north); West Plains Regional Airport (1.3%, 95 kilometers, south); and Springfield-Branson National Airport (0.9%, 121 kilometers, southwest).
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.

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.
