Purpos:
Apply the optimal settings for the region of interest that was
determined with:
~/papers/Extreme-WTs-US/programs/Extreme-WTs/SearchOptimum_ExtremeEvent-WeatherTyping.py
1) Read the PRISM and ERA-Interim data
2) Calculate the WT centroids
3) Plot the Centroids
3) Calculate Eucledian Distances for each day
4) Plot ED vs. PR accumulation
