The National Weather Service has issued a wind chill advisory throughout the day for many counties throughout Illinois, Iowa and Missouri, including Washington County.
According to the advisory, the advisory remains in effect until noon, with bitterly cold wind chill temperatures from -15 to -28 expected throughout the area. Light snow will spread into the western part of the outlook area, after 10 p.m., when it is expected to move eastward across the rest of the impacted area into Thursday morning. The Washington area is expected to see snow after midnight. Generally light snow accumulations are expected, but areas north of Interstate 80 and west of the Mississippi River may receive 1 to 2 inches of snow by sunrise Thursday.
Snow-induced slick spots and temporary reduced vision may be expected for the Thursday morning commute.
The service also reports light snow is expected through Thursday morning with up to an inch of accumulation possible east of Dubuque to Princeton, Illinois. A band of light snow will then move to the northeast of the area. Thursday afternoon and early evening, snow showers may develop ahead of an incoming frontal system. If these snow showers develop, they may be able to produce temporary reduced visibilities and localized additional accumulations.
More light snow is expected Friday, especially south of Interstate 80, where an inch or two is possible. There is a low chance of additional light snow Saturday in the far southern portion of the outlook area.
People should expect additional periods of bitterly cold conditions late this week and into the weekend. Wind chills of 15 to 25 below will be common Friday, Saturday, and Sunday nights.
Very cold wind chills continue through today. The cold wind chills will cause frostbite in as little as 30 minutes to exposed skin. Expect wind chills to range from 15 below zero to near 30 below zero throughout all of Eastern Iowa, northeast Missouri, and northwest Illinois. A Wind Chill Advisory means that cold air and the wind will combine to create low wind chills. Frost bite and hypothermia can occur if precautions are not taken. Make sure you wear a hat and gloves.
