The members on the weather forum I belong to are snickering their heads off over the Accuweather winter forecast. They are commenting on its low caliber and erroneous graphics; the bit about 75% of 0 inches for Miami snowfall has come in for a lot of sniping. Basically Accuweather is generating sloppy, purposely vague predictions, and trying to drum up paying customers.
If you want more accurate analysis, you might want to check out NOAA and NWS [winter predictions should be out by the end of Oct] and the following sites: http://www.wxrisk.com/
or if you want to find the comments of a several top mets and some very good amateurs then join http://www.easternuswx.com/bb/index.php?
which is the best by far the best option. I never use Accuweather; historically, their long range predictions [1-2 weeks] have usually busted. Thing is you never suspect that because they tweak the predictions daily so the original prediction is always overwritten.
I use EasternUSWx forum posts to guesstimate a couple of weeks ahead whether conditions will be good for a long weekend at SS. It takes a little work, but so far, the system has been right on the money and we have had totally awesome conditions during our trips!
