The Met Office has revealed which areas of NI experienced the warmest weather this week as cooler temperatures move in over the weekend.
This week has been hailed as a bonus week of summer with sunshine across NI.
A large area of high pressure across the UK is contributing to the rise.
The warmest day in Northern Ireland this month was on September 6 which was 27.2C in Killowen, Co Down.
The warmest September day on record in NI was at Castlederg in Co Tyrone on 8 September 2023.
The warm spell began on Monday when the highest temperature was 21.8C in Derrylin.
Temperatures peaked on Tuesday at 23.7 in Magilligan, on Wednesday a high of 22.5C was recorded at Giant’s Causeway and 22.7C in Armagh on Thursday.
Meteorologist Zoe Hutin said: “We are expecting to see a turn to cooler conditions over the coming weekend and into next week, although largely dry and settled conditions are expected for Northern Ireland.
“Mist and patchy fog are likely to form in rural parts on both Friday and Saturday morning, but the first part of the weekend is set to be cloudy and rather calm.
“Generally light winds for most, though breezy along the east and northeast coastlines.
“Overnight on Saturday and into Sunday morning there is a risk that scattered showers may spread into southern parts, however the thunderstorm risk remains low for Northern Ireland.
“Drier conditions are set to return by the afternoon with occasional sunny spells, though expect it to feel cooler going into next week, with temperatures around average for the time of year.”
Heavy rainfall is expected to drench many parts of the UK with up to 70mm of rainfall expected within a few hours after a spell of dry, warm weather.
While some weather warnings are in place, Northern Ireland appears to be escaping the worst of the bad weather.
Meanwhile, there are two yellow weather warnings for thunderstorms for Friday and Saturday, covering most of south-west England, parts of Wales, the Midlands and west London and is in place from 12pm until 8pm.
The second warning is in place all of Saturday from 1am and covers all of Wales and south-west England, the Midlands and parts of south-east England.
