The first round of light snow Monday night brought generally an inch or two to the Mississippi and Illinois Valleys.
Officially, in the Quad Cities, in Moline, Illinois, 1.6″ fell.
This brings us up to 13.8″ for the month of December, making it the 15th snowiest December on record, and more snow is on the way later today!
A “Winter Weather Advisory” goes into effect at noon Tuesday and will continue through noon Wednesday for the counties shaded in light blue north of the Quad Cities. This is where the heaviest snow over the next 30 hours will fall.
However, we’ll all see snow.
Since this will be a light, fluffy snow, we’ll have to deal with blowing snow, too.
It’ll be very cold Wednesday night through Friday night. However, the coldest air of the season arrives early next week!

Happy Eve of New Year’s Eve!
It’s snowing in the Quad Cities, just as I predicted, so I thought I’d give you a quick update.
The snow is moving rather quickly through the area and should be out of here by midnight. Accumulations tonight will be generally less than one inch.
Our next clipper system arrives tomorrow afternoon with more snow likely.
A “Winter Weather Advisory” goes into effect at 3 p.m. Tuesday through noon Wednesday for the purple shaded area north of the Quad Cities above. This is where the heaviest snow will fall through noon Wednesday.
This long duration snow event will finally come to an end late Wednesday night or early Thursday morning.
Beyond noon Wednesday, we could still see accumulating snow.
When the snow finally ends late Wednesday night or early Thursday, the heaviest snow will across the north.
From around Maquoketa and Dubuque, Iowa, eastward to Galena and Mount Carroll, Illinois, 4-6″ of snow are likely.
Along and just north and south of Interstate 80 in Iowa and Illinois, including the Quad Cities and Galesburg, Illinois, 2-4″ are likely.
South of the Quad Cities, from Burlington, Iowa, to Macomb, Illinois, you may only see about an inch or two of snow.
With any snow event, there could be isolated higher totals in any of these locations.
Glancing at the late afternoon forecast models, the NAM (shown above at noon Wednesday) is definitely generating more snow that the GFS.
Since this is a long duration, three-day event and several pieces of energy are involved in the snow production, make sure you join me early Tuesday morning on CBS4 from 5-7 a.m. for the latest on Tuesday’s and Wednesday’s snow.
