Hail Fog

Fog sometimes forms after a good round of hail. The hail doesn’t have to be large, there just has to be a lot of it. Hail will cool down the air immediately above it, bringing the air temperature down to the dew point and causing saturation and in turn, fog. Hail also contributes moisture to the hail as it absorbs heat, melts, and evaporates. On some occasions, hail fog can make for very abrupt and dangerous drops in visibilities on roadways due to the isolated nature of where hail falls.

The following photos were taken near Wabasha by Joe Dick today at 5:30 pm, on County Road 30 from US 61 to upper County 24.
