Some changes coming up.
A cold front crosses the region Wednesday night, brining a chance of freezing drizzle and light snow to the area before it passes; accumulations should be very light.
A trough of low pressure will hang back from the low as the system continues east.
As this previous low pressure departs, a new low will form along this trough someplace around Davenport, Iowa.
At the same time a weak low pressure may be sinking south across the Dakotas.
The models bring the Dakota low south and the Iowa low strengthens as it moves north over Lake Superior. This will bring North and Northwest winds across the region beginning the invasion of arctic air. Initially this cold air will bring another round of lake-effect snow to the south shore of Lake Superior on Friday.We will have to watch how much snow may fall.
Cold Temperatures on their way.
Temperatures will begin to drop after the Dakota and Iowa low pressures. The map (to the right) is a screenshot from the NWS Graphical Forecast, showing expected low temperatures on Saturday morning.Most of Wisconsin will be be between 0 and -15, with colder temperatures even farther north. International Falls has a forecast low of -24.
This clip (to the left) is from today's WGN blog from Chicago.
It's a great visual to show where our cold air will come from -- that top blue arrow comes from Siberia, across the Arctic Ocean, down through northern Canada and into the north-central States.
