Actual snowfall amounts? 12 to 18 inches... I'd say that's just a little more than what was predicted... :lol:
 
From NWS GRR Area Forecast Discussions Snippets:
WAA/ISENTROPIC ASCENT CONTINUES TO FUEL THE BAND OF SNOW
THE BAND OF SNOW OVER THE NORTH IS ALSO BEING AIDED BY A NICE AREA OF MID LEVEL FGEN IN PLACE. DEFORMATION/TROWAL FORCING.

Possibly some Lake Effect action? Still no reason why the forcast was that far off.

Then again the August 18, 2005 tornado outbreak in WI only had a slight risk put out.

Weather can be mysterious sometimes.
 
"Possibly some Lake Effect action?"

No, this was all overrunning. Just hard to EVER call for numbers that high, let alone without model support.

I had to drive from Davison to Flint this morning, the fog and blowing snow was incredible. I-69 westbound, the entire way, was between 25 and 45 mph driving speed with several vehicles well off the road (I almost slid off twice at overpasses).

We had about a tenth of an inch of ice accumulation and an inch of powdery snow. About thirty miles north, it just dumped. As soon as I heard the thunder, I knew it was going to snow much harder than the NWS had forecasted.
