Winter’s going to be colder than usual and next summer hotter.  So says the Old Farmer’s Almanac, the familiar, 223-year-old chronicler of climate, folksy advice and fun facts.  Published Wednesday, the almanac predicts a “super-cold” winter in two-thirds of the country, or what Editor Janice Stillman calls “a refriger-nation.”  Before unpacking the parka, remember “colder than average” is about 2 to 5 degrees difference.  The almanac says summer will be warmer than usual in most places while a drop in rainfall in the country’s midsection could hurt crop yields.  It says next year’s hurricane season isn’t expected to be especially active though a major storm could hit the Gulf Coast in late August.
