Rime Ice vs Hoar Frost
Rime ice and hoar frost are commonly misidentified. The process in which the ice crystals form are different between the two. Rime forms as super cooled water droplets freeze on contact commonly forming needle like structures. Rime is most common with freezing fog. Ice structures may be wind driven with rime occurring on the downwind side of what the droplets are freezing on to. Hoar frost will occur on clear and cold nights when water vapor condenses directly to the ice phase referred to as deposition, and the ice structures that form during this process are feathered in appearance. It commonly happens on snow fields as water vapor accumulates near the surface as the snow warms up during the day and then deposits at night as temperatures cool (a.k.a. surface hoar). Surface hoar will scatter light in all different directions given off a sparkly sheen to the snow.
Snow Depth
As of Thursday, January 5th, the MSP Airport recorded 16" of snow on the ground. Interestingly, this tied for the 11th greatest snow depth on record for January 5th! My guess is that cross country and snowmobile trails are going to be packed this weekend!
