Temperatures will average 1 to 2 deg below normal values (more so with daytime highs than overnight lows). Rainfall will average 25 to 50 per cent above normal in the south, near normal in central counties, Leinster and Ulster, and locally about 25 to 50 per cent below normal in parts of Connacht. Sunshine will average only about half the normal amount, and winds will continue mainly rather light, occasionally moderate by the weekend.
TODAY will see another outbreak of heavy showers and local thunderstorms, some producing hail, over the inland southwest but this time they seem more likely to remain in place, moving only very gradually into parts of the southeast by later in the day. Some parts of Connacht and Ulster may have a generally dry day, with a few brighter spells. Leinster will see variable amounts of cloud and isolated showers. Highs for all regions close to 14 C. About 15-25 mm rainfall potential in counties of west Munster, 5-15 mm east Munster into south Leinster.
TONIGHT will bring a gradual end to the showers in the south and some clear intervals with rather cold overnight lows as a result (2-7 C).
WEDNESDAY to FRIDAY the weather pattern will be relatively stagnant with similar outcomes each day, mostly cloudy skies and scattered outbreaks of showers and thunderstorms, some with hail. On the average most places can expect to see 5-10 mm rainfalls each day but this could be locally as high as 15-20 mm. Highs each day will be around 14 C, overnight lows generally around 5 C.
By SATURDAY an approaching Atlantic frontal system will bring intervals of rain, and it will remain showery on SUNDAY with highs both days around 14 C. Rainfalls of about 10-20 mm are likely over the weekend. By MONDAY there could be outbreaks of heavier rain as this next system does roughly the same as the last one, grinding to a halt near Ireland for several days.
The rest of NEXT WEEK then looks unsettled and similar to this week. Longer term guidance begins to show a bit more variation in temperature with warmer air sometimes getting involved although not dominating, so that by the fourth week of May there could be some days reaching highs closer to 20 C.
