Weather Whys: Why did the snow forecast change so drastically?

Why did our snow forecast change so drastically? It's a question many across southern Wisconsin are asking this morning after we went from the possibility of a good whooping of snow Sunday and Monday morning to hardly any snow by Monday afternoon. It's a question we're answering in today's Weather Whys. 

Meteorologists rely on weather models to make accurate forecasts and for most of Friday, Saturday and Sunday those models were showing a good helping of snow in southern Wisconsin. By Sunday afternoon we started to see a trend with the storm to the south but it still painted a lot of snow in southern Wisconsin. It wasn't until the Monday afternoon weather models that big changes happened. 

Some of our southern communities still have the chance to see a little bit of snow this evening into tomorrow morning. Some light lake effect is also possible. If snow happens, which is still in question, expect less than an inch.
