Did you know that we’re entering the “Foggy Season” in the Midwest? Yes, there is such a thing. During November, December, and January, we have the lowest sun-angle of the year. You will notice this by the long shadows you have even during the middle of the day. The sun is near to the horizon these days and those less-direct sun rays aren’t enough to burn off the fog quickly in the mornings.
But even though we have longer days and stronger rays in January and February, we stay in the Foggy Season. That’s because we get a lot more moisture above the ground during the late-winter months. This is due to snowmelt and the fact that the ground is often times frozen. Warm days melt off the moisture on the surface which produce higher relative humidity levels in the atmosphere. This air can become saturated, causing us to have more foggy mornings in January, February, and March.
By April, our foggy days become fewer and fewer as we have less moisture and more intense sun rays.
Today is Day #2 of fog! While the fog won’t be as bad as yesterday, we will still have some thick spots so drive safely!
