After looking at tonight's data I'm lowering the snow forecast for the Quad Cities slightly. Quite honestly I don't like to change the forecast right before a storm arrives but I can't just ignore what I've seen so far this evening. It will still be a decent snow in the metro area, but instead of 5-7 inches it's now looking more like 4-6".

Now for the all-important question - how much snow? In the Quad Cities everything is coming together for a total of 5-7" and there could be some higher amounts just down to the SE. Conversely, slightly lower totals are likely NW of the metro area...
