Now that the wintry mix has transitioned over to all snow and temperatures are slowly starting to fall, the snow will quickly add up.
Earlier today, I was forecasting 1-3″ for the Quad Cities. I think it’ll be on the higher end of that range and there could be some isolated 4″ totals.
Be safe this evening and early Tuesday morning on area roadways.

Power outages are becoming more widespread as we head toward the noon hour with the winds really beginning to howl and shake the ice-coated limbs and power lines.
As of 11:30 a.m., more than 4,400 MidAmerican Energy customers are without electricity. Ameren Illinois is reporting about 6,500 customers in our area without power, but Peoria is the hardest hit with more than 12,000 customers in the dark!
Freezing rain, sleet, and snow is coating everything. This is how my car looked in Rock Island around 10 a.m. after more than six hours of freezing rain and sleet.
Many reports of one-quarter to almost an inch of a freezing rain and sleet combination with almost two inches of snow covering the ground around Cedar Rapids.
This is the radar around 10:25 a.m. this morning and it shows there’s still plenty of moisture heading toward the Mississippi and Illinois Valleys.
This will come down as a combination of freezing rain, sleet, snow, and rain this afternoon before changing to snow tonight.
Here’s how much of a snow and sleet mixture may accumulate before it ends early Tuesday morning.
Be safe out there today in this icy and dangerous mess.

The much advertised winter storm is already glazing roadways, trees, and power lines across the Mississippi and Illinois Valleys. This started late Sunday night and by the early morning hours, the wintry mix had reached the Quad Cities.
A “Winter Storm Warning” remains in effect for much of Monday and Monday night and runs through 6 a.m. Tuesday for most of us. It expires this afternoon across the southeast around Galesburg, Illinois.
Here is how big the surge of moisture the storm has to with to produce freezing rain, sleet, snow, and rain. This was 3 a.m. Monday morning.
Temperatures early this morning are already below or near the freezing mark and that will make the commute dangerous from Interstate 80 southward.
The northward progression will worsen driving conditions across the north throughout the morning.
As temperatures warm into the 30s today, the wintry mix could change over to rain, at times, in the Quad Cities and for several hours across the south and help to melt away some of the early morning ice.
However, as temperatures drop again this evening, the rain, freezing rain, sleet, and snow combination will change to all snow and continue through part of the night.
On top of the more than one-quarter of an inch of ice, we could see snow accumulations of 1-5″. One inch totals down around Galesburg, to 1-3″ in the Quad Cities, and maybe 3-5″ totals around Iowa City and Galena.
The higher totals (4-8″) will be well northwest of the Quad Cities.
If this wasn’t bad enough winds of 20-40 miles-per-hour and gusts to 50 will be whipping around the ice covered limbs and power lines causing power outages.
Much colder air arrives by the middle and end of the week with a little bit more light snow Wednesday.
Be careful out there today, tonight, and tomorrow. This isn’t just a typical Midwestern winter storm with the ice.
Winter has returned.
