Experimental: An Indicator for March Rockford,ILL / KRFD Snowfall Within The February U.S. Meridional Wind Anomaly Distribution

This is kind of an experiment to see if these type of correlating indicators work as shown by the map. If so, maybe forecasts like this can be used for snowfall, precipitation, and temperature for different cities across the world. This is an example of using the previous months V-Wind across the United States as a harbinger for KRFD Snowfall. Other indicators could be anything from sea-level pressure, SST's, or even stream function on a sigma level. This begs the question about the typical "Correlation With Causation Argument". The March Snowfall Average was calculated using March 1951-2012 Snowfall, which averaged out to 5.5 inches. We'll come back to this to see if it worked or not.......
