Snow is still on the way later tonight and early Tuesday, but the start time will be delayed until late this evening.
The storm will begin as a wintry mix of rain, snow, sleet, and freezing rain across the north and it’ll move southward toward the Quad Cities.
It’ll transition to all snow north by this time and it’ll be in the midnight to 6 a.m. time period when the changeover to snow happens for the metro area.
The start of the “Winter Weather Advisory” and the “Winter Storm Warning” has also been pushed back to 9 p.m. It still runs through 9 a.m. Tuesday.
As for snowfall amounts, I’m leaning more to the lower side of the ranges that I presented this morning.
While there could be an isolated 6″ total north, most totals will be 3-5″. In the Quad Cities and north of Interstate 80, an inch or two seems more likely.
More snow is likely Wednesday night and Thursday.

You know you live in the Midwest when you have record warmth one day and a winter storm the next day.
After reaching 66° in the Quad Cities Sunday tying the record high for the date, snow is on the way Monday night and early Tuesday.
We’ll enjoy one more warm day Monday with highs well into the 50s. Some southern hometowns may hit 60° again.
A wintry mix develops across northern hometowns Monday evening and this will start out as rain across southern hometowns.
As a cold front pushes south and low pressure moves across Missouri, colder air will be drawn into the system and that combination of rain, sleet, freezing rain and snow Monday evening will be changing over to snow for most of the area.
A “Winter Weather Advisory” goes into effect at 6 p.m. Monday through 9 a.m. Tuesday for Cedar, Clinton, Dubuque, Jackson, Jones counties in Iowa and Carroll and Whiteside counties in Illinois.
Additionally, a “Winter Storm Warning” has been issued Jo Daviess and Stephenson counties in Illinois.
Snowfall amounts will be heaviest across the far north in the “warning” area. 3-6″ may fall there. Along Interstate 80 northward, 1-3″ seems more likely. South of I-80, hometowns may see anywhere from a trace to an inch.
There’s still some uncertainty as to where the heavy snow bands will set up. That 3-6″ range could shift north or south some later today. Stay up on the latest forecast.
Along with the snow, gusty winds are also going to make it more wintry and more difficult for travelers.
