Charts ( up to T120) Winter 2025/2026 **READ MOD NOTE IN FIRST

As the cold spell gradually eases and the Atlantic reasserts itself, aided by a jet stream energised by cold air over North America, the risk of low pressure systems barrelling toward Ireland increases. One such system is indicated for Sunday night into Monday morning, bringing the potential for strong winds, particularly in the northwest. The outlook for next week is unsettled, with further spells of rain and occasional strong winds likely to persist.

A rare Red Alert in place for southwest Cornwall and the Isles of Scilly. Gusts of 100 mph+ expected

Only an amateur learning as I go along but firstly going by the ECM as a guide the indices which are showing the potential for mixed wintry precipitation crossing the country tomorrow evening with freezing rain in places. So to my knowledge you are looking at surface temperatures in places at around freezing or below with Dew Points below freezing and above the surface level you have a shallow inversion of warmer air and above that you have the colder column of air aloft getting cooler with height ( On the skew-T chart the red line leaning to the right is the inversion before turning to the left -getting cooler with height ).

A feature like a decaying occluded front or / and trough are set to cross the country tomorrow evening ( bearing in mind that the 528dam line is down over much of the country, polar airmass, bringing the the 500mb layer down lower ; aiding snow development but not always so ), possibly only a relatively small amount of precipitation but when it falls it could fall as rain, sleet or snow depending on elevation and local conditions and also fall as freezing rain in places i.e. the precipitation initially falls as snow or a form of ice and liquifies when passing through the inversion layer closer to ground level but remains supercooled and freezes on impact when it reaches the freezing surface.

Not a lecture just qualifying my earlier post and I am sure there are much more learned people out there with more a scientific insight 🙂

A few showers moving inland tonight could fall as freezing rain locally i.e. over a relatively small area.

That could be freezing fog up in Northern counties tomorrow evening with temps set to get as low as -3 or -4C quite early in the night.

As WolfEire said above becoming unsettled and getting windy later Saturday through Sunday and into early Monday . Models seem to be pulling the strongest winds offshore on latest runs , will see in further runs but still might be expecting yellow wind warnings up along the W, NW

Temperatures set to be relatively mild getting up over 10C along the Western coasts Sat night and 8 or 9C inland, Sunday could see temps getting up as high as 11 or 12C or a bit more in a few places.

Highest rainfall accumulations along Coastal counties.
