Cold snap Jan 10th onwards: Wintry Showers, Snow Accumulations for some

A westerly just doesn't bring proper snow. 850 hPa temperatures and 500-1000 thicknesses do not guarantee snow. Met Eireann were 100% correct with their "conservative" forecast. Next time maybe people will listen.

If you suspect a rereg then report it - please don't speculate on-thread

Thanks guys

@FWVT So are you saying Monday night/Tuesday will be another non event in your opinion? From the West again but I believe it always meant to be more likely than today

I think you need to grow up a little bit to be perfectly honest.

At no stage did anyone say that any sort of event was going to occur. This thread is also split in to two - one for yesterday, one for midweek but such nuances are conveniently swept aside in favor of attacking other posters, saying things that were never said and taking things out of context (on purpose).

Can we move on now?

Monday evening onward should be the focus now and there is a lot to focus on.

Folks,

Snow showers becoming heavy and frequent in the northwest and north early Saturday morning should extend to many other places (but not all) during daylight hours with the potential for significant falls in the northwest particularly later Saturday evening. The far southeast could stay dry.

I wouldn't be as pessimistic as Iancar29 regarding snowfall at low levels on Saturday nor how widespread precipitation may be given most of the variables are on the right side of favourable but I agree with Redsunset to a certain extent that the bigger "prize" potentially is from Monday night. Lots of interesting outcomes available for the following few days. It's not a question of whether we will get snow but rather how much and in what form because there is a hint around midweek that a secondary low from the southwest might interact with this air mass bringing potentially a longer period of sleet and snow to some places for a while. But it's too early for specifics.

12z's out soon. We can start going in to more detail at this stage for the weekend anyway.

But I know some get frustrated with the language we have to use here at times and how it can seem unclear, indecisive and confusing.

It will turn much colder this weekend with snow showers on Saturday and Saturday night. Most of these in the northwest and down along the west coast so places like Derry, Sligo, Galway, Limerick etc have a real chance of snow but some getting through to other areas as well. Temperatures during Saturday in low single figures. Slightly milder for Sunday and part of Monday before potentially even colder weather returns again bringing more snow showers and low temperatures.

There is little or no difference tomorrow north or south. All the variables are met for showers to be of snow well in to the early hours of Sunday morning. Don't worry

As long as you are away from an immediate windward coast in the west your chances of seeing snow (even in Cork ) are quite high. Obviously showers by their nature are hit and miss but even allowing for this they should be plentiful and heavy and dragged to most places on a pretty strong wind. I think most will at least see snowfall tomorrow. As to whether it settles the northwest is the best hope there. But later tomorrow night there should be settling snow elsewhere as well.

Gone by daylight Sunday - next Tuesday and Wednesday looking ever more interesting though.

As Pistolpete says this is not an "event" and should not be treated as such. Any disruption should be limited to the north west.

From around 9 am on wards away from direct windward coasts that is when the cold air digs in and the showers turn to snow although they will be snow at higher levels before that and that is where the bulk of any accumulation of snow will be.

Through the day the showers will keep coming though the far southeast could stay dry throughout. Favored locations for any significant falls are the north west and just inland of the west coast in Connaught. Showers further east always more scattered and not as heavy.

Progressively colder through the day. To give some idea of the pace of the fall later on it's progged to be around 12c in the east circa 4am and down to 4 or 5c a couple of hours later. It's a fast steep transition. Temperatures gradually rising from the west during the early hours of Sunday morning with showers dieing out and the snow level rising again.

The air mass is not quite as cold as was progged up to yesterday evening (the south and southwest barely touching -5c 850hPa temps) but none the less you can see already how today pans out with frequent showers in the northwest and close to Atlantic coasts, more isolated further inland. For Connaught (away from immediate windward coasts), Ulster and North Leinster it looks like a fun day. The southwest, even inland, is much more marginal now for snow at low levels.
