Please put this forecast in context. Central Arkansas averages 3.5 inches of snow per year. If Joe forecasts 150 to 200% of average, that's roughly 5-7 inches. I have seen that much snow fall in just a few short hours. As far as temperatures are concerned, he is forecasting seasonal temperatures about 3 degrees below average. That's chilly!
There's no doubt you will hear the term, "El Nino" in the media, but that's only one piece of the puzzle. There are other factors influencing our weather. I'll give you an example. A few years ago, a La Nina was occurring. Forecasts were for a dry and mild winter, but it turned out to be one of the coldest and snowiests in more than 20 years. Why? The Arctic Oscillation was strongly negative for most of the winter and that tends to suppress the storm track pushing cold air deep into the south. The AO is tough to forecast more than a couple weeks out.
Again, Joe has done a great job and his forecasts deserve you attention. Check out his blog at Weatherbell.com and follow him on twitter @BigJoeBastardi.
