FWIW, the last few runs of the HRRR want to maximize lift in the DGZ for the NW suburbs for several hours with temps near freezing. If this comes to fruition then we certainly could see some problems with power lines and the roads.
Starting to get some Jan 27, 2011 vibes for the NW crew. You have:
1.) A dynamic, strengthening system moving through to the south.
2.) Rain to start so no pretreatment can be put down on roads.
3.) Heavy rates.
