Winter Weather Advisory through Monday

Weather

A Winter Weather Advisory has been issued for all of northern Illinois and southern Wisconsin beginning at 9pm Sunday night, lasting through Noon Monday. Temperatures across the area are currently in the mid and upper 30s, but are falling to the north into the 20s. A strong, Arctic cold front came through early Sunday morning but the cold air is lagging a little behind the front.

Where the snow is beginning to develop is where the leading edge of the cold air is currently. Temperatures are expected to fall through the rest of the evening, overnight and into Monday morning down into the low 20s. Initially, precipitation across the local Stateline may begin as drizzle or light rain showers early Sunday evening, but by 9pm/10pm the majority of precipitation should be coming down as snow. Light to moderate snow will continue through Monday morning before ending from north to south early afternoon.

A total of two to five inches of snow will be likely, with two to three inches falling during the overnight, and another two to three inches falling through the morning. Impacts to the commute Monday are likely with slick roads and reduced visibility. North winds will at times be gusting 25-30mph, and this will cause the snow to blow around as it falls, but also cause snow to drift and blow across roadways even after it stops.

Roads will likely be slick in the morning so give yourself the extra time you need to get to work, school, appointments, etc. There will likely be some impacts to the late afternoon and evening commute, especially for more open and rural roads/areas.
