  1. Looks like the entire “Mitten” of lower Michigan is lake effect snow right now, massive contrast between the lake temperature and air temperature because, although I’m not from Michigan, I grew up in a neighboring state, so I’m gonna wanna say this is about a month early for snow, and especially these frigid temperatures.

  2. Interesting. Now a “ridge” normally refers to warm air aloft and also at the surface. If they are referring to an arctic high pressure area, then it would be called an arctic high (at the surface) underneath a deep upper trough at 500mb. This allows the polar jet to swing south around the base of the trough and allows a flow of arctic air into those regions. At the surface, the strong arctic high building into those areas allows cold air advection to overspread those regions – often accompanied by gusty NW winds and strong pressure rises. If the arctic high settles directly overhead overnight, record lows are possible since the coldest readings are usually near the center of the arctic high during clear skies and calm winds. (when radiational cooling is best)
