KSTP Chief Meteorologist Ken Barlow said snowfall in the Twin Cities is expected to affect Thursday morning's commute.
The snow, which arrived after midnight, is expected to last through the early part of the morning commute.
Although accumulation is only expected to be between 1 to 3 inches, timing and temperatures could still make for a slow commute.
Because temperatures are expected to be low, there is a chance the snow will glaze into ice once driven over. MnDOT official Kent Barnard also voiced concerns about Thursday's road conditions
"Once we get down around 5 degrees above zero to zero, regular rock salt which is what we have on the roadways quits working," Barnard said.
With nearly two inches forecasted to fall, Barnard said crews will hit the road early, but that they will not be spreading as much as as normal.
The trucks will likely scatter a small amount of salt-brine mixture, but the cold temperatures will slow down how quickly it works.
"We will have some slick spots out there," Barnard said ."We will get what's called refreeze, where the snow will melt from temperatures of tires and vehicles and re-freeze on the roadway."
Temperatures on Thursday are expected to reach a high of 13 degrees. Temperatures on Friday are expected to drop to 4 degrees. Weekend temperatures are not expected to rise above zero degrees.
Meanwhile, the National Weather Service reported International Falls and Hibbing set record low temperatures Wednesday. International Falls, the self-proclaimed Icebox of the Nation, plunged to 37 degrees below zero, while Hibbing bottomed out at 28 below.
