  1. We (the North West) can get snow from any angle, some angles favour certain areas more than others, and some seem to cash in no matter what. This year the snow has come mainly from the south as our cold has come mainly from the east and precipiation has been in the form of Atlantic lows coming up and hitting it. This favours the south of the region as the cold to the north east prevents the lows moving too far north, and if they do cross the whole region, they push the cold away turn to rain anyway. In 2009/10 our cold came from the North due to Greenland high pressure, we all cashed in then as the wind was slightly west of north and the Irish sea created convection. That is ideal for the otherwise entirely snowless north and west of Lancashire. In a direct easterly, so beloved of our southern cousins, we are generally sheltered from snow coming off the North Sea by the Pennines, this is also true of a north easterly and even straight northerly's, but the western downslope of the Pennines, like Oldham and Macclesfield can get hit. And there are also places, like Saddleworth, the Buxton area, and the north Pennines around Alston in Cumbria, that get snow regardless of the direction of the wind, due to their greater exposure to easterlies, and added height in marginal westerly types.

    Thanks thats a great post.

  2. Alright folks dont post much on here but like to read the forums, living in Sale south Manchester we rarely

    get any snow here and after the last event it got me asking why. From reading here its the shadow effect but could anyone explain in laymans terms what this is and why Manchester gets rain and not snow? also what weather system do we need to see snow here?

    Thanks guys.
