A fast-moving Canadian clipper system will keep us cold and bring us some Wednesday night snow showers from about 10pm to 4am. For Burlington and north and northwestward, a good dusting to a half inch or so should fall. Accumulating snow will sharply cut-off heading southward to Fort Madison and especially Keokuk. If you’re holiday traveling — north to Interstate 80, including the Quad Cities, a good 1 to 2 inches should be common Wednesday night into early Thursday morning.
Thursday will then feature some cloudiness and an opportunity for some flurries and a few isolated snow showers. Thursday night will be dry.

Friday, another snowy wave dives in from the north. It’ll be more ambitious than the one for Wednesday night. Between about 9am and 9pm Friday, I’m anticipating 1.5 to 3.5 inches of snowfall for most of us.
There may end up being a very narrow band of slightly higher amounts. Temperatures will be cold and range from around 10 to 18 degrees as this snow falls. That automatically adds more room for error in snowfall forecasting. Through that temperature range, you get a snow-to-melted-down-water ratio of 18-30 to 1 — much more impressive than most snow we see around here at our typical snowfall temperatures in the upper 20s to lower 30s that have snow to water ratios of 10 to 1. Then, it depends on how much of the storm occurs at various temperatures — lots of moving parts.
That gets us to Friday night when snow will be tapering down earlier in the evening. We’ll be on the northern fringe of minor snow to our south this weekend. You’ll want to keep an eye on weather forecasts if you’re traveling toward Kansas City.
Cold for how long?
It could be a while. Our current weather pattern combined with any fresh new snow will ensure temperatures will not make it above 20 throughout the entire week ahead. At the moment, computer models don’t show us even approaching the freezing mark until the weekend of January 6th and 7th. That would be among our longest of cold stretches.
