    is there some larger force at work in the weather, beside the usual day to day fluctuations that caused such a wet and dreary summer followed by the record autumn we've just experienced.

    i think i can remember johnny eagleton mentioning something about the jet stream having shifted position one night but can't recall his exact words.

    We did have a meridional jet stream for a long time in autumn, unfortunatly its zonal all the way currently - http://squall.sfsu.edu/gif/jetstream_atl_h12_00.gif

    When the jet is over our shores it means a winter like 2006/07 ie:a zonal flow of atlantic storms one after the other crossing close too or over us.

    The only thing different is the jet is not as far north as last winter,so cold will be accompaning mild this time round.
    The further the jet moves south,the more chance that high pressure will build to our north or north west and will allow cold polar air down upon us.Untill then the atlantic is going to be very mobile for the foreseeable.
