The northern Indiana office of the National Weather Service issued an Area Forecast Discussion this afternoon that reveals meteorologists thinking about the coming winter storm. Here are some highlights (translating contractions as necessary):

“Concerns loom that models are not capturing full potential of the system and that much more snow could occur than presently forecast as well as track further northwest.”

“At this time the highest is confined to southeastern half of the (office’s forecast) area but as noted genuine concerns that this axis could be shifted northwest.”

“Travel Sunday into Monday will likely become difficult if not impossible especially in rural areas where significant drifting will occur.”
