Is a mid December iceing headed our way?

December 11, 2016 – About five days from now, say along about Saturday, December the 17th or so, the weather may take an interesting turn, as a vigorous and fast moving system swings across the Midwest. This from the NWS: 'Will there be winter travel weather problems on Saturday? While the post frontal precipitation won't be overly heavy, global models do indicate a potential light wintry mix quickly transitioning from rain, to freezing rain, to snow (or freezing drizzle if we lose cloud ice). Will mention this in very general terms in the forecast in the coming days. Given how cold it will become, some degree of travel impacts could be possible.'

Update: Dec 15 - Snow chances dissipating! As a matter of fact, we may not experience hardly any precipitation until our next frontal system pushes through the region on Saturday. The GFS and ECMWF still indicate a band of snow developing behind the front, potentially bringing only a dusting to some locations with the highest chances along and to the north of the I-44 corridor. Many areas may not receive any accumulation at all given the very progressive nature of this band of snow. However, there will likely be the wind gusts, reaching 30 mph at times behind the arctic front with frigid wind chill values not seen thus far. Wind chills near -15F will be very possible!
