The storm tonight, Friday, and possibly Saturday belongs to a decreasing PNA/+AO teleconnection regime, the best pattern for heavy snow in Wisconsin. Next week we head deeper into this pattern with a deeper western trough digging in the southern stream. Mid-range models are not that interesting for Wisconsin. They do show a storm system during the 2/13-2/16 timeframe crossing the country further to the south. Maybe models change to support a bigger storm in future runs? At this moment I'm betting that the peak time for this pattern is our current system as we flux into the western trough. Just not thrilled with next week yet.
