Cold weather ahead
September's sunny spell of Indian summer weather looks to be at an end with Met Éireann forecasting a chilly change that will feature changeable and unsettled weather for the rest of the week and weekend.
Met Éireann says the weather from Tuesday will feature heavy rain, strong winds and cooler than normal temperatures as autumnal Atlantic weather sweeps in over Ireland.
The forecaster expects the wettest days look to be Tuesday, Thursday and perhaps Sunday/Monday.
As for temperatures Met Éireann says the next week will be considerably below what we would expect for late September, generally 2 or 3 degrees below normal. It says Wednesday through to Friday could feature night time temperatures in the low single figures at times with the probability of grass frost. Temperatures will recover to near normal later in the weekend.
In contrast to the last seven days when sunshine levels were double the average in some places, the next week is expected to be closer to or below normal.
The forecaster issued the following summary national outlook on its website on Tuesday, September 22.
"Changeable and unsettled weather for the rest of the week and weekend. Cooler than normal up to and including Saturday, but temperatures will recover a little by the end of the weekend," it said. More below tweet
