Driving home from rural parts of Carver County late this evening was more interesting than I thought it would be. Had about 1/2 an inch on roads with windblown snow going across the highways already though nothing all that significant at the time. There were already 3 cars off the roads at different points, but the roads really didn't seem to warrant sliding as long as you were driving somewhat cautiously. The visibility was more of a problem than anything causing me and the car in front of me to slow down to 35-40mph(on 55mph hwy) at spots. The car in front also couldn't figure out where the road was, as he drove on the shoulder for much of the time.

Interesting trends here. Rapid intensification can result in some intense winds...and this is already showing. Models have nothing in Iowa right now....already G to 45 at KPRO/sustained at 39 with some RWIS sites reporting 40 G as well.

Ain't a dam thing you can do with a ripping se and east wind a lot of the storm.. Low is just way to close.

That is terrible. I have had that happen to me many times as well. You get excited for the storm and then you are disappointed because it rains by the lake. Good luck to you anyways.

Nice hit for parts of IA/MN/WI/IL.

This is a bit further south than the 12z.

Yeah, it is unfortunate. I could see it coming the whole storm, but I thought the SE trend would allow us to overcome that warm east and southeast wind. This would be a perfect track if not for temps. Pretty similar to the December 9th storm last year, except the low tracked right through MKE.
