Our next weather comes early Friday morning as a low pressure system arrives from the west, bringing some snow on hills on its leading edge in the southern half of the country, in a moderate southerly wind.
The system is currently deepening south of Greenland, as upper divergence increases in the left exit region of a strengthening jet streak.
By 7am Friday morning the system becomes vertically stacked and reaches its minimum pressure of around 988hPa just off the Kerry coast. Precipitation rates will have reached their peak by then and will start to decrease as it pushes eastwards across the country. Still, it will initiall give spells of snow on hills above ~250m, especially in the southwest, but will turn more and more to rain as the warm sector crosses the south.
By midday Saturday, the backbending occlusion should still be giving some spells of precipitation, rain for most, but with snow lowering to around 200m later in the day behind it. By that stage precipitation should be dying out as a transient ridge approaches Saturday night, giving a cold night and a bright start to Sunday.
