Wet & mild spell before settled and fresher weather arrives next week – Thurs 7th October
Met Éireann have issued a yellow rain warning for western parts of the country through Thursday and Friday, as prolonged and heavy rain will likely lead to localised flooding and tricky driving conditions.
Met Éireann meteorologist, Paul Downes, said: “Whilst eastern part of the country will see some showers or rain over the next few days, it is the western half of the country that will see a spell of very wet weather with prolonged and often heavy rain. Mountainous regions in the west and southwest of the country will see the heaviest rainfall, with in excess of 70mm falling in some of these areas within 48 hours. This will lead to some localised surface and river flooding especially for hilly areas, with some disruption to transport and tricky driving conditions possible.”
A stream of tropical air will bring mild and wet weather
The reason behind the wet weather is due to a slow-moving weather front from the remnants of ex-Hurricane Sam. This weather front will stall over the western half of the country bringing a spell of prolonged rainfall to western counties, but it could edge over eastern areas at times bringing some spells of rain to eastern counties too.
Meteorologist Paul Downes continued: “Friday evening in particular will see the heaviest rainfall, although this will mainly be focused across western areas before spreading east overnight. Saturday will see another cloudy and damp start but it’ll gradually brighten up from the west as the weather front clears into the Irish Sea, with cooler, drier and brighter conditions following in the east by Saturday afternoon.”
Temperatures on Thursday and Friday will be very mild around 16 to 20°C, the average October temperature in Ireland is around 10°C. Thursday and Friday night will be mild too with temperatures around 12 to 16°C. This mild tropical airmass will be replaced by a fresher polar maritime airmass through Saturday, with temperatures returning closer to normal for the time of year as well as cooler nights.
High pressure building next week
An area of high pressure will gradually build through the weekend bringing more settled and drier weather into next week. There will still be some rain and drizzle around at times, especially in the north, but for many it’ll be dry next week with some spells of Autumn sunshine.
