A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. The chance of wet days in Franklin varies throughout the year.

The wetter season lasts 4.2 months, from April 19 to August 26, with a greater than 33% chance of a given day being a wet day. The chance of a wet day peaks at 44% on May 29.

The drier season lasts 7.8 months, from August 26 to April 19. The smallest chance of a wet day is 21% on January 28.

Among wet days, we distinguish between those that experience rain alone, snow alone, or a mixture of the two. Based on this categorization, the most common form of precipitation throughout the year is rain alone, with a peak probability of 44% on May 29.

Rainfall

To show variation within the months and not just the monthly totals, we show the rainfall accumulated over a sliding 31-day period centered around each day of the year. Franklin experiences significant seasonal variation in monthly rainfall.

Rain falls throughout the year in Franklin. The most rain falls during the 31 days centered around May 18, with an average total accumulation of 3.6 inches.

The least rain falls around January 29, with an average total accumulation of 1.6 inches.

Snowfall

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. Colder, drier snow tends to be on the higher end of that range and warmer, wetter snow on the lower end.

As with rainfall, we consider the snowfall accumulated over a sliding 31-day period centered around each day of the year. Franklin experiences some seasonal variation in monthly liquid-equivalent snowfall.

The snowy period of the year lasts for 4.8 months, from November 11 to April 6, with a sliding 31-day liquid-equivalent snowfall of at least 0.1 inches. The most snow falls during the 31 days centered around February 11, with an average total liquid-equivalent accumulation of 0.7 inches.

The snowless period of the year lasts for 7.2 months, from April 6 to November 11. The least snow falls around July 10, with an average total liquid-equivalent accumulation of 0.0 inches.

The length of the day in Franklin varies significantly over the course of the year. In 2017, the shortest day is December 21, with 9 hours, 28 minutes of daylight; the longest day is June 21, with 14 hours, 52 minutes of daylight.

The earliest sunrise is at 5:52 AM on June 14, and the latest sunrise is 1 hour, 55 minutes later at 7:47 AM on November 4. The earliest sunset is at 4:55 PM on December 5, and the latest sunset is 3 hours, 50 minutes later at 8:45 PM on June 28.

Daylight saving time (DST) is observed in Franklin during 2017, starting in the spring on March 12, lasting 7.8 months, and ending in the fall on November 5.

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.

Franklin experiences significant seasonal variation in the perceived humidity.

The muggier period of the year lasts for 3.3 months, from June 5 to September 15, during which time the comfort level is muggy, oppressive, or miserable at least 10% of the time. The muggiest day of the year is July 24, with muggy conditions 39% of the time.

The least muggy day of the year is February 23, when muggy conditions are essentially unheard of.

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 Franklin experiences mild seasonal variation over the course of the year.

The windier part of the year lasts for 5.7 months, from November 8 to April 29, with average wind speeds of more than 2.9 miles per hour. The windiest day of the year is February 24, with an average hourly wind speed of 3.8 miles per hour.

The calmer time of year lasts for 6.3 months, from April 29 to November 8. The calmest day of the year is August 13, with an average hourly wind speed of 1.9 miles per hour.

The predominant average hourly wind direction in Franklin is from the west throughout the year.

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 experiences significant seasonal variation over the course of the year.

The brighter period of the year lasts for 3.9 months, from April 29 to August 26, with an average daily incident shortwave energy per square meter above 6.0 kWh. The brightest day of the year is June 23, with an average of 7.0 kWh.

Temperature and Dew Point

There are 4 weather stations near enough to contribute to our estimation of the temperature and dew point in Franklin.

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

The stations contributing to this reconstruction are: Grant County Airport (29%, 42 kilometers, north); Jennings Randolph Field (33%, 53 kilometers, northwest); Shenandoah Valley Regional Airport (24%, 57 kilometers, southeast); and Ingalls Field Airport (13%, 88 kilometers, southwest).

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.
