Saturday/Sunday Wintry Potential

Lots of interest this weekend as some cold uppers move over us Saturday night into Sunday. Could be quite a bit of snow falling and possibly lying by the end of the weekend. After such a mild Winter nice to at least see a bit of late potential!

Certainly looks wintry JanuarySnowstor. The charts are starting to show fair accumulations in the North of the Country . I think it was HighDef that pointed out it is a very similar set up as last Sunday but the snow falling more North. This time als the uppers are colder.

Do you think there could be disruptive road conditions for Sunday? Just wondering will a Sunday event in Kildare be impacted.

Thanks!

If it's similar to last weekend, yes it's likely roads conditions (and congestion) will be impacted. What do expect when everyone uses summer tyres all year round??

Like last weekend, it's going to be unpredictable where will and will not get impacted. Nowcasts are likely to be the best info.

Wind gusts from the ARPEGE . Not a storm but quite windy on coasts. Warnings will be issued more than likely, probably yellow for wind , could get a yellow for snow and Ice also.






Quite windy also from the ECM and blustery across the country



ICON looking quite windy Sunday.




a different set up from the WRF - NMM but still showing snow accumulations , even in the SW

HIRLAM HI RES just coming into range .

Models differing, looks like not as much moisture available this time so accumulations may be less but it looks colder so lying snow might last longer.






Accumulations by 07.00 . AROME did well last weekend

Oscar Bravo had posted this already , will add it here also as important to this thread.


--------------------------------------------------------------

From met Eireann

A highly mobile Atlantic regime looks set to dominate our weather pattern through this weekend and the coming week. This will bring a sustained period of unsettled, often very windy and at times wintry weather with showers of hail, sleet and snow.

https://www.met.ie/forecasts/atlanti...ation-pressure

A very strong Jet Stream will help to push some vigorous and potentially disruptive Atlantic weather systems over Ireland during the period.

Strong and blustery winds look likely to feature from Saturday (9th March) through to at least Wednesday (13th) with frequent gales at sea. Sea conditions will be very rough and there will be exceptionally high seas and swell in Atlantic coastal regions at times.

There is certainly potential for warnings to be issued over the coming days, so please do stay up to date with the Met Éireann forecast.

I could be wrong, but I don't think snow will be nearly as widespread as it was last Sunday. Most of the snow looks confined to the North-West and Northern Ireland. By tomorrow evening we should have a better guess at where the snow will fall and by how much.

Looking at the temperatures a bit closer for Sunday and at the moment you would think they are too high for settling snow on lower ground in general during daylight hours. Looks quite cold Sunday morning so snow may be on the ground already in parts of the Northern half of the country, how long it will last ? Looks like a showery day Sunday giving wintry falls. Would expect that if it falls as snow then it would only settle on high ground during the day.

Still a bit to go models still not fully aligned even at this late stage.

Hirlam is going for mostly rain away from the north and high ground locations on Sunday.



GFS shows more snow potential and usually overdoes it



Icon is excluding the snow to Northern Ireland.



Arpege is a rain to snow event with most snow over the north.

I think if its too windy therel be no snow. The last snow we got in NW at end of January was because cold air was calm. This windy weather will bring snow to Northern Ireland but only slight amonts to Sligo.

Dont see many areas outside Ulster getting much.

Very short lived too once the sun gets to work on it Sunday

Still March seems to be our new Winter
