The GFS is the only model really indicating this setup at present. Interesting to see if others will follow suit in the next day or two. |

And so the rollercoaster begins... ECM is now indicating for the first time that colder weather will push westwards towards Ireland as a high build over the arctic and eastern Scandanavia This image depicts upper air (1500m) temperatures |

Here is Peter's take on the latter half of the weekend into the early days of next week. OUTLOOK ... Damp and rather cold in a developing easterly flow. Some risk that this will turn wintry but certainly not very mild (highs at this point would seem to be 4-7 C on average for several days) |

Only issue here is that the GFS is pushing out the extreme cold with every run. They had indicated the 15-17th Feb up to 3 days ago. At least more of the weather models are now in agreement that colder weather is likely after mid month |

Im still optimistic about the cold , the models are changing too often , so thats the sign that tells ya, even the models dunno what the feeek is gonna happen. Hopefully now , we get the Greenland high building up to help us hold back the atlantic for an advance of some siberian air! Until then i shall stay infront of the models all day.... all nite.......

Just looking at the ECMWF in isolation, I am not overly encouraged. The run remains on the cool side throughout but 850 temps are only slightly below normal (between 0c & -4.0c)![]() Chilly at best, non-descript and totally without character at worst. No sign of any major winter storms either. |

The colder air is not to far away in FI but at the min looks like the UK are best positioned to see either a beasterly or a battlefront scenario over them,any one got some straw handy so i can clutch a bit more....... |

So am I Ian, but as you say the models aren't telling us much. [Any more than the models can really tell us about Climate Change]

Yet another rollercoaster ride,I favour another cold blast from the east, which could become fairly dominant for at least 5-10 days ay time from the 20th onwards -c-h-i-n |

Latest from iWeather Online's Peter O'Donnell SUNDAY … Damp and chilly with mixed precipitation possible on higher ground in the north, otherwise cold rain showers and highs of about 5-8 C. OUTLOOK … A rather cold week with winds generally E to SE. Some rain at times, with the risk of sleet or snow but so far this seems mostly marginal or on highest terrain. Much colder weather will be spreading into nearby parts of Europe so this forecast is subject to change as we get closer to the time. |

DelW is right in what he said about trend being your friend. There is a trend for colder weather but the models are not showing up anything dramatic. Next Monday looks like this on the ECM The -4-8c temps in that image relate to the upper air (1500m) temperature. It is generally regarded that uppers need to be around the -8 mark in order for snow to fall. Of course there are many factors but these uppers are a good gauge of whether weather will be cold. |

Would feel a lot better if any of the models had the low in the Atlantic further south than they do,but that's probably me being pessimistic again -c-h-i-n chart watching at it's best

More than likely at low levels,generally snow needs -6 to -10 uppers for snow,as this is coming in from the Atlantic maritime air will be in the equation as well,possibility if heavy enough precip. |

IWO's Peter O'Donnell's take on weather In the pattern developing for Ireland over the next week, there will be a lot of marginal precipitation situations so anyone in higher parts of the north especially should be expecting some snow each time there's mention of sleet or even rain. As temperatures will never drop low enough to allows for sustained periods of snow to develop, wintry precipitation may come and go during the events. Snow is also likely to show up on summits further south too. TODAY ... Mostly dry and rather cold. Some sunny intervals. Light winds. Highs 6-8 C. Rain, with some higher elevation sleet or wet snow arriving in west late this afternoon, wintry precipitation turning to rain this evening. TONIGHT ... Intervals of sleet or rain. Temperatures in the east near 2-3 C for part of the evening, closer to 5-6 C west, but in each case rising somewhat before morning. FRIDAY ... Morning showers, a few sunny intervals later. Highs around 10 C. Becoming foggy in the late evening and overnight. SATURDAY ... A frosty and in some places quite foggy start to the day. Morning lows near -1 C, then brighter intervals to follow, then sleet turning to rain late afternoon and evening ... risk of measurable snow over higher parts of Connacht and Donegal, west Ulster ... highs 8-10 C. SUNDAY ... Rain ending before dawn in west, continuing for part of the day over eastern counties, slow clearing, rather chilly. Lows 2-4 C and highs around 7 C. OUTLOOK ... Showery, cold for several days next week, with winds northwest at first, turning more to east mid-week, possible wintry precipitation over higher terrain, highs only 5-7 C on average. |

This very well could be the extent of any cold spell around mid February Jessie. Having said that weather models all disagree with each other on extent of any warming trend. Keep checking back here for updates. |

OUTLOOK for TUESDAY to THURSDAY … a rather cold and unsettled period, with winds becoming east to southeast … at the moment, it does not look cold enough for snow except perhaps on higher terrain in the north and east, but it may be a close call with highs 5-7 C and overnight lows near freezing, somewhat below in any clearing intervals. This cold spell may end with strong winds and heavy rain as milder air tries to push back in late in the week. |

Latest from accuweather's Joe Bastrdi LONDON NOT AS COLD AS LAST WINTER! We continue to fade as London for the winter is 2.3 below normal while last year at this time it was 3.6 degree below normal. Given the extreme December cold, the reversal has been almost dramatic and driving home the point about the worst of winter being up front. I do think a return lurks in March for a time, but by that time the kind of extremes that would have caused a problem had they returned in mid winter would have been a threat that was merely a ghost. But it is official... last winter was colder than this one. |
