Cold sets in, dangerous wind chills possible
The National Weather Service in the Quad Cities has issued a hazardous weather outlook for portions of north central Illinois, northwest Illinois, west central Illinois, east central Iowa, northeast Iowa, southeast Iowa, including Jefferson County, and northeast Missouri.
Gusty northwest winds associated with an arctic cold front will combine with very cold temperatures to produce dangerous wind chill values Wednesday night and Thursday.
Wind chills may range from 20 to 30 below zero during this period across most of the outlook area. Some areas north of Interstate 80 may even have wind chills colder than 30 below zero Thursday morning.
A clipper type low pressure system will bring the chance of light snow accumulations to the outlook area Friday night.
Gusty northwest winds behind this system also may produce some drifting snow late Friday night and Saturday morning. This may produce localized slick spots.
Longer range indications suggest that more arctic air and gusty winds surging into the area will bring the threat for additional rounds of dangerous wind chills from Sunday into Monday.
