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 Baxter is rapidly decreasing during August, falling from 76% to 56% over the course of the month.

For reference, on July 25, the muggiest day of the year, there are muggy conditions 80% of the time, while on January 14, 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 Baxter is essentially constant during August, remaining within 0.1 miles per hour of 2.0 miles per hour throughout.

For reference, on February 25, the windiest day of the year, the daily average wind speed is 3.5 miles per hour, while on July 30, the calmest day of the year, the daily average wind speed is 1.9 miles per hour.

Average Wind Speed in August

The average of mean hourly wind speeds (dark gray line), with 25th to 75th and 10th to 90th percentile bands.
The hourly average wind direction in Baxter throughout August is predominantly from the south, with a peak proportion of 33% on August 31.

Wind Direction in August

The percentage of hours in which the mean wind direction is from each of the four cardinal wind directions (north, east, south, and west), excluding hours in which the mean wind speed is less than 1 mph. The lightly tinted areas at the boundaries are the percentage of hours spent in the implied intermediate directions (northeast, southeast, southwest, and northwest).

Solar Energy

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 Baxter is gradually decreasing during August, falling by 0.7 kWh, from 6.5 kWh to 5.8 kWh, over the course of the month.

Data Sources

This report illustrates the typical weather in Baxter year round, 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 4 weather stations near enough to contribute to our estimation of the temperature and dew point in Baxter.

For each station, the records are corrected for the elevation difference between that station and Baxter 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 Baxter is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Baxter and a given station.

The stations contributing to this reconstruction are: Crossville Memorial Airport (39%, 55 kilometers, southeast); Smyrna Airport (25%, 80 kilometers, west); Glasgow Municipal Airport (18%, 102 kilometers, north); and Wayne County Airport (17%, 105 kilometers, northeast).

Other Data

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.
