Inclement weather watch Thurs 12th / Fri 13th March 2026

At the moment looking rather windy over the Northern half of the country later Weds night into Thurs morning, a blustery day Thurs and possibly getting quite windy in the Southern half later Thurs, spells of windy weather through Fri night into Fri in places but models still getting a handle on it. Currently the stronger winds look like getting into the yellow warning level in my opinion.

Rainfall amounts fairly high up to Fri especially along the Western half of the country more so towards the coastal counties with Thurs looking like the wettest day. Later Thurs into Fri the very cold airmass moves across Ireland with the 528dam line well South across the Atlantic and in over parts of Ireland. The unstable active atmosphere introducing many showers of rain , sleet, hail and snow with thunderstorms a possibility especially later Thurs into Fri more so towards Atlantic coastal counties.

Models predicting snow showers which might accumulated later Thurs night into Fri morning but temps not staying cold enough for much to settle into Fri so may be a slushy wet mix on the roads for a time, as always any falling on higher ground might last longer. Could be some heavy hail showers also making local conditions tricky at times. Some of the wintry precipitation may be accompanied by windy conditions adding to difficult visibility and slippery roads.

Showers convective in nature so might produce heavy local blustery precipitation .

Temperatures falling quickly from the West Thurs afternoon as it gets increasingly wintry , initially maybe up to around 12C but getting down to low single digits by nightfall, maybe as low as 3C or 4C , some frost in sheltered areas, cold day on Fri especially feeling cold / raw in the wind with frost overnight into Sat morning in some areas.

Cold fronts , troughs and unstable airmass spreading in from the Atlantic over Ireland later Weds through Thurs becoming increasingly cold later Thurs into Fri as the 528dam line moves over the entirety of Ireland with wintry showers of rain, sleet, snow and hail with possible thunderstorms .

I see above Met Eireann giving a country wide yellow warning over Ireland, probably wise as the winds sweep across the country beginning in the NW and could get fairly strong as the day progresses for a time. Very hard to accurately predict timing at this stage and some areas may lull for a time . The very nature of the convective showers also giving locally strong blustery and squally downdraughts.

24hr rainfall accumulations don't seem to be too bad for now, widespread 10 to 15mm, touching around 20mm in places along Atlantic coastal counties especially over higher terrain, some models showing Donegal getting high precipitation totals.

Snowfall looking heaviest atm in the NW/ N but the W could also get a bit of a covering in places for a time as could areas down along the Atlantic Seaboard but amounts small but could be nuisance to transport early Fri morning as the showers could be blustery making driving a bit difficult. Very noticeable windchill Fri.

Very big seas also developing and over the weekend also.
