A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. In Stony Plain, the chance of a wet day over the course of January is gradually decreasing, starting the month at 9% and ending it at 7%.
For reference, the year's highest daily chance of a wet day is 35% on July 3, and its lowest chance is 5% on February 12.
Probability of Precipitation in January
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 January in Stony Plain is essentially constant, remaining about 0.3 inches throughout, and rarely exceeding 0.7 inches or falling to 0.0 inches.
The highest average 31-day liquid-equivalent accumulation is 0.3 inches on January 8.
Average Monthly Liquid-Equivalent Snowfall in January
Over the course of January in Stony Plain, the length of the day is rapidly increasing. From the start to the end of the month, the length of the day increases by 1 hour, 18 minutes, implying an average daily increase of 2 minutes, 36 seconds, and weekly increase of 18 minutes, 15 seconds.
The shortest day of the month is January 1, with 7 hours, 35 minutes of daylight and the longest day is January 31, with 8 hours, 53 minutes of daylight.

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 Stony Plain is essentially constant during January, remaining around 0% throughout.
For reference, on July 24, the muggiest day of the year, there are muggy conditions 0% of the time, while on January 1, 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 Stony Plain is essentially constant during January, remaining within 0.2 miles per hour of 9.9 miles per hour throughout.
For reference, on January 30, the windiest day of the year, the daily average wind speed is 10.1 miles per hour, while on August 11, the calmest day of the year, the daily average wind speed is 7.7 miles per hour.
The highest daily average wind speed during January is 10.1 miles per hour on January 30.
Average Wind Speed in January
The hourly average wind direction in Stony Plain throughout January is predominantly from the west, with a peak proportion of 52% on January 3.

Definitions of the growing season vary throughout the world, but for the purposes of this report, we define it as the longest continuous period of non-freezing temperatures (≥ 32°F) in the year (the calendar year in the Northern Hemisphere, or from July 1 until June 30 in the Southern Hemisphere).
The growing season in Stony Plain typically lasts for 4.3 months (131 days), from around May 12 to around September 20, rarely starting before April 23 or after May 30, and rarely ending before September 2 or after October 8.
The month of January in Stony Plain is reliably fully outside of the growing season.
Time Spent in Various Temperature Bands and the Growing Season in January
Growing degree days are a measure of yearly heat accumulation used to predict plant and animal development, and defined as the integral of warmth above a base temperature, discarding any excess above a maximum temperature. In this report, we use a base of 50°F and a cap of 86°F.
The average accumulated growing degree days in Stony Plain are essentially constant during January, remaining around 0°F throughout.

Temperature and Dew Point
There are 3 weather stations near enough to contribute to our estimation of the temperature and dew point in Stony Plain.
For each station, the records are corrected for the elevation difference between that station and Stony Plain 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 Stony Plain is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Stony Plain and a given station.
The stations contributing to this reconstruction are: Edmonton Stony Plain Alta. (65%, 8 kilometers, west); Edmonton / Villeneuve Airport (26%, 18 kilometers, northeast); and Edmonton International CS , Alta. (9%, 37 kilometers, southeast).
All data relating to the Sun's position (e.g., sunrise and sunset) are computed using astronomical formulas from the book, Astronomical Algorithms 2nd Edition , 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.
