Graphical Model Predicted Average Snowfall Error/Bias For PHL For This Cold Season

Recommended Posts

This is the average forecast bias for each event (or non event).  In order to qualify some model had to predict at least .1" water equivalent and some snow in one of their forecasts.  The snowfall algorithmic methodology is not the same across the board, so this should be used more as a general idea, than an absolute value.  I couldnt get the models stacked up against each other, I am not good with excel graphics. 

The white arrows separate the models.  I did one for the GFS by itself too.
