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 Howard Lake is gradually increasing during May, rising from 0% to 4% over the course of the month.
For reference, on July 20, the muggiest day of the year, there are muggy conditions 36% of the time, while on November 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 Howard Lake is decreasing during May, decreasing from 11.8 miles per hour to 10.3 miles per hour over the course of the month.
For reference, on April 2, the windiest day of the year, the daily average wind speed is 12.4 miles per hour, while on August 2, the calmest day of the year, the daily average wind speed is 8.4 miles per hour.

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 Howard Lake typically lasts for 5.3 months (160 days), from around April 28 to around October 5, rarely starting before April 10 or after May 15, and rarely ending before September 17 or after October 23.
The month of May in Howard Lake is more likely than not fully within the growing season, with the chance that a given day is in the growing season rapidly increasing from 60% to 100% over the course of the month.
Time Spent in Various Temperature Bands and the Growing Season in May
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 Howard Lake are increasing during May, increasing by 280°F, from 117°F to 397°F, over the course of the month.

Temperature and Dew Point
There are 5 weather stations near enough to contribute to our estimation of the temperature and dew point in Howard Lake.
For each station, the records are corrected for the elevation difference between that station and Howard Lake 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 Howard Lake is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Howard Lake and a given station.
The stations contributing to this reconstruction are: Maple Lake Municipal Airport (30%, 21 kilometers, north); Buffalo Municipal Airport (29%, 21 kilometers, northeast); Hutchinson Municipal Airport (15%, 33 kilometers, southwest); Glencoe Municipal Airport (14%, 34 kilometers, south); and Litchfield Municipal Airport (13%, 35 kilometers, west).
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.
