TODAY will start out rather cloudy with the best chances for morning sunshine in the west and south, as patchy light rain or drizzle moves slowly out of eastern and northern districts. By mid-day the sunshine or at least brighter conditions should spread into the east, but then low cloud and sea fog will begin to drift inland in some western districts, dimming the sunshine at times there. In this rather changeable mix, highs will probably be able to reach 20 or 21 C in some southern and eastern locations, about 18 or 19 C in central parts, and 17 C in the western third as well as across the north.
TONIGHT there may be another interval of cloud and light rain moving across the north and brushing the east coast towards morning. Amounts will be light, around 1-2 mms at most. Many southern and western locations will have some fog or mist but no measurable rain. Lows will be around 11 to 13 C.
MONDAY is likely to bring warmer sunshine to roughly the same parts of Ireland as the previous two days, mainly the inland south, southeast and east, with highs to about 22 or 23 C there. It will likely remain rather foggy with low cloud and drizzle in some western coastal districts, with highs near 17 C, and the north could stay cloudy much of the day with highs of about 18 or 19 C.
TUESDAY the wind direction will reverse from the very light NW'ly flow of previous days, to a slight SE'ly and this will tend to redistribute the coastal fog and low cloud more to the south and east coasts, leaving most inland and western districts sunny, warm and dry. However, there may be some isolated thunderstorms forming in central districts. Highs will be about 24 C inland and west, and 17-19 C south and east coasts.
WEDNESDAY to FRIDAY at present show a tendency for winds to back from southeast to northeast, which will likely take a few degrees off the warmth especially in the eastern third of the country, but in general it should stay rather warm and dry, with a slight risk of showers in one or two locations. Highs should be mainly around 22-23 C, cooler in the north and near the east coast. With this change in wind direction, the south coast could benefit by having a drier and warmer wind off the land rather than sea breezes.
