This warmer air aloft moving atop cold air near the surface results in what is known as a temperature inversion. Basically, we have a layer of warm air in the atmosphere that acts like a lid, trapping in clouds and fog near the surface.
Why are there so many cloudy days in the winter?
During colder weather, temperatures are more likely to reach the dew point temperature, producing saturated conditions and clouds are more likely to form. Also, a more active storm track causes storm systems to move through more often, making clouds more common.
Is Wisconsin always cloudy?

Why is the Midwest so cloudy in the winter?
The cold air several thousand feet above the ground associated with these low-pressure systems creates instability, generating a deck of stratocumulus clouds that can lag behind the storm for a day or so. Any brief peek of sunshine is quickly filled in by more stratocumulus clouds.
Is it warmer when it’s cloudy in the winter?
This leads to warmer temperatures. However, if skies are cloudy, some of the sun’s rays are reflected off the cloud droplets back into space. Therefore, less of the sun’s energy is able to reach the earth’s surface, which causes the earth to heat up more slowly. This leads to cooler temperatures.
Why is it so foggy in Wisconsin?
On Wednesday and Thursday, the air over southern Wisconsin was fairly moist, which is typical of late spring and early summer, Cronce said. “When you have moist air over this relatively cool water, that generates fog,” Cronce said. “This is common occurrence in the spring and early summer.”

How do people survive winter in Wisconsin?
Layers are important. Start with a base layer (merino wool or long underwear is a good option), add a mid-layer of fleece or wool, and finish with a windproof layer. Mittens are better than gloves, since they trap heat from your entire hand, and a hat is better than a headband, for the same reason.

Which state is the sunniest?

There’s a reason why so many people migrate to Arizona and don’t fly back for the winter. Phoenix, Tucson, and Flagstaff are all in the top 25 sunniest cities in the US, and Phoenix ranks #1 with an annual sunshine rate of 85.8%.
Why is the Midwest so GREY?
The atmosphere grows colder, and the coldest layer of air is at ground level. Colder air under warmer is stable, and condensation and cloudiness tend to be horizontally stratified, resulting in widespread and long-lasting overcasts.
Why is it not sunny in winter?
In contrast, when that spot on the earth is tilted away from the sun in the winter, the sun is in general lower in the sky, and it receives less direct sunlight. Less direct sunlight means that the sunlight is coming in at a low angle, so that it is smeared across a greater area when it hits the surface.
Why is it less sunny in winter?
During winter, the Northern Hemisphere leans away from the sun, there are fewer daylight hours, and the sun hits us at an angle; this makes it appear lower in the sky. There is less heating because the angled sun’s rays are “spread out” rather than direct. (Shadows are longer because of the lower angle of the sun.)
