The differences in amounts between these news outlets gets ridiculous and is probably the reason why so many people get caught offguard by these storms. Every news station wants to be the best when the ultimate goal should be to come up with the most accurate forecast for the public in terms of snowfall amounts. I mean you have one station calling for 3-6" while another is calling for 8-12" for the same area, to me that is a big difference which has happened plenty of times in the past.. Not everyone will channel through to see the forecasts for different stations and most usually watch only one news outlet.
I really think there needs to be more and better coordination and communication IMO.
