    PS. When you consider that we haven't seen northern blocking during a winter month for NINE years this is a very encouraging chart if you ask me.

    Not strictly true now... a recent example, albeit late in the season.

    the next 6 days look cold with showers or rain/sleet in places, possible hill snow. Milder with south-westerlies from about the 20th of December and very wet up to Christmas Day. After Christmas remains very much up in the air. There is a slight chance of something much colder happening right after Christmas.

    Ah yes, those famously accurate 168 Hour + charts

    they can be inaccurate but sometimes can give a good indication of whats to come. It seems fairly believable that the unsettled theme will continue for the time being with a very active Atlantic since September and very weak signals of northern blocking.

    You don't need northern blocking for the Atlantic to settle down
    A bloated Bartlett high would do it :pac:

    interesting video this evening by Gav.

    Basically there may be hints of a pattern change which could start to happen after Christmas. The AO/NAO may go from positive to negative and the Beijing Climate Center wants to introduce strong northern blocking for January.

    This in no way guarantee's cold for us but I would really welcome a pattern change, like most people i'm completely fed up with all the rain of the past 3/4 months and would love to see the Atlantic shutting down for a few weeks minimum. This could lead to us to something colder and also dryer as we head into the new year.

    I think the Beijing Climate Center has been out on its own predicting blocking for our locale this winter, so kudos to them if it does indeed happen.

    The cold we have had since November is just an annoying cold that doesn't really deliver anything worthwhile. Cold zonal weather often leads to the feeling of real chill, bone shaking damp winds and cold rain which is really not enjoyable. I find if you get a cold easterly, it can be much colder in terms of temperature but the real feel may not feel as chilly, especially if it's a dry easterly with crisp, sunny and frosty conditions, it can even be quite pleasant. Even snowy days from an easterly can often not feel as chilly as a zonal based cold weather and you get the benefit of seeing some beautiful winter postcard scenes around.

    2 more dry days to go and then we are back to square one in terms of rainfall. Milder and very unsettled from Wednesday. Those rainfall spikes look worrying as the land here hasn't really had a chance to properly dry out from the deluges of the past 3 months. It wouldn't take many wet days to bring back the risk of flooding.

    Towards the end of the run we see alot of scatter in terms of temperatures, most are mild but there are a few outlying cold runs which almost get us into the freezer as we head towards New Years Day.

    The rainfall also looks like it will ease a little after Christmas. From Wednesday to Christmas Day looks like a very wet spell indeed. Hopefully we will see the situation after Christmas evolve into a dryer and colder scene.

    I said yesterday I am totally up for a major pattern change which could hopefully bring an end to this incredibly wet and prolonged wet spell. The Atlantic has been raging since mid September with very little let up, I remain hopeful that it will run out of steam during January or February.

    Heavy deluging rain. Dark... drab

    Encouraging signals on the long-term ECMWF this morning that we could be seeing some nice, drizzly, humidity saturated warmth as we head into January. And with the added bonus of not having any Winter storms, or even anything of slightest meteorological interest, to concern ourselves with:

    More runs needed, but the signals are looking good.

    Strange day in cork city. While the stations say 5 degrees etc, my house received no sunlight today (north facing + low winter sun) so theres still frost on my roof + in the garden. Garden thermo says its about 0-1 degrees + some slippy footpaths outside

    the long range models have been signaling a dire winter season filled with mild muck for quite some time now. let's hope they are wrong and fail to the same extent as last winters long range models.
