An early-season snowstorm has spread into the Plains and Midwest after bringing several inches of snow to the Rockies earlier in the week.
A southward plunge of the jet stream from the Rockies into the central United States has entrenched a pipeline of arctic air over those regions.
An area of low pressure is tapping into that cold air and producing a stripe of snowfall from the Plains to the Midwest.
The Weather Channel has named this system Winter Storm Bessie.
Scattered areas of light snowfall are ongoing this morning from Colorado to northern Illinois.
A burst of heavier snow moved through the Chicago metro area early Wednesday morning. Western suburbs of the city received 1 to 3 inches of slushy accumulation.
Light snow in Denver should continue to taper off through the day. The Mile High City picked up 7.7 inches of snow at Denver International Airport.
The area of low pressure will strengthen near the Great Lakes on Thursday, wrapping in cold air and possibly allowing accumulating snow to fall in parts of Illinois, southern Wisconsin and northern Lower Michigan.
Rain changing to snow could then pivot through parts of the Great Lakes through Thursday night, including Indiana, Michigan, northern Ohio and northwestern Pennsylvania.
