TONIGHT will be clear at first with haze, then fog and mist may become fairly widespread at least in the east and north. Lows 10 to 14 C.

SATURDAY and SUNDAY will continue similar to today, perhaps about a degree cooler in most areas, and in the north there may be more persistent cloud at times with isolated outbreaks of drizzle or light rain. Lows 9 to 13 C for Sunday morning, and highs both days 22 to 25 C in central and western counties, 18 to 22 C east and north.

MONDAY to THURSDAY will continue this fine spell of weather although there could be a very gradual decline in temperature back towards more normal values, but even so, highs 21 to 24 C are possible in some parts of the west, south and midlands. Highs 17 to 20 C will be more typical for Leinster and Ulster, at least closer to the coasts.
