Freezing Rain Advisory for Chicago 1/21

Freezing Rain from Iowa to Indiana

If you have plans to fly into O’Hare Airport or Midway Airport, deicing will be needed today the 20th into Thursday  the 21st.  I used to work on the ramp for America West Airlines at O’Hare  Yes, I wore a burgundy jump suit and had a blast driving the tugs/carts and talking to the pilots on the headsets while pushing back the plane.

Last check, the temperature was 32, the freezing mark in Chicago, with moisture moving into the city.  A Freezing Rain Advisory started at 3pm and goes until 6 am on Thursday the 21st of January.  Ice accumulations of around one tenth on an inch is the forecast, the evening commute will likely be slick. Be alert when driving or walking

What’s causing the Freezing Rain ?  Well, high pressure will remain parked over SE Canada, this high will feed the cold low level air in on pretty strong easterly winds.  Low pressure over Northern Missouri will pump in the moist air and that moisture will override the cold air at the surface producing the freezing rain event.
