The least rain falls around January 22, with an average total accumulation of 1.5 inches.
Average Monthly Rainfall
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. Springfield experiences some seasonal variation in monthly liquid-equivalent snowfall.
The snowy period of the year lasts for 4.3 months, from November 15 to March 25, 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 1, with an average total liquid-equivalent accumulation of 0.4 inches.

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.
Springfield experiences extreme seasonal variation in the perceived humidity.
The muggier period of the year lasts for 4.0 months, from May 22 to September 22, 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 23, with muggy conditions 69% of the time.
The least muggy day of the year is January 31, when muggy conditions are essentially unheard of.

This report illustrates the typical weather in Springfield, 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 Springfield.
For each station, the records are corrected for the elevation difference between that station and Springfield 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 Springfield is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Springfield and a given station.
The stations contributing to this reconstruction are: Springfield-Branson National Airport (93%, 9 kilometers, west); Branson Airport (3.5%, 76 kilometers, south); Waynesville-St. Robert Regional Airport (1.9%, 118 kilometers, northeast); and Lee C Fine Memorial Airport (1.8%, 118 kilometers, northeast).
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.
