    Will wait for a Kermit thread before getting excited. Looks like marginal stuff so far. West coast might get some slushy white gold at times.

    It is marginal but I think that the northern third could have a high chance of seeing snowfall, especially in such a showery setup.

    I wanted to let people know that the Netweather posts aren’t reflective of the forecast situation on our island.

    ECM's 0Z showing snow potential Thurs with what looks like a wave feature forming from NW to SE over Southern half of Ireland and deepening, followed by another disturbance later from N to S. Difficult to know if this will happen like this but something like it could happen. Mid levels very cold showing getting down to -5C, -6C and cold uppers. DP's coming right down during the day to below freezing by early night.

    Certainly looks wintry, probably something like rain to sleet to snow to sleet and rain, wet snow on the ground on hilly areas, snow on mountains. Early yet to know but has the signs of getting the first taste of winter proper.

    Very cold night to follow into Fri morning so there could be some lying snow possible and icy roads.

    Not sure what happened to the icon? The cold comes in on Wednesday and then disappears? Hopefully just a blip.

    I will watch the 18z with baited breath.

    The ECM is showing it colder than ICON at this stage, still holding on to -5, -6C 850hPa temps. ECM not as snowy on this run, more in the way of rain and sleet but I'm sure twists and turns will happen over the coming days.

    GFS coming in on the act showing snow potential for the SE , the timing for this run is snow later Thurs night into Fri morning.

    There are going to be bands of precipitation, troughs and convective showers all in the mix, timing is impossible atm. Wont know with any degree of certainty up until a day or so beforehand and then it will be a nowcast in such a marginal set up but interesting nonetheless.

    The ICON 18Z has went back to the previous pattern. The cold arrives in on Wednesday morning (for Ulster) and leaves on Friday.

    It appears Ulster and some places south of that have a very high chance of seeing snow showers between Wednesday and Friday, but no lying snow.
