“Around the middle of next week, pressure will build – the Azores high,” said BBC weather presenter Cecilia Daly, who is based in Belfast
“This would allow our weather to take on more normal summer characteristics.”
The jet stream has been stuck hundreds of miles further south than normal this year.
But it’s about to move north – and could bring much warmer and drier weather.
Forecasters are hoping it will move north enough so that we here in Donegal also see the benefit of the weather change.
Met Eireann is forecasting much drier and sunnier weather for Friday and Saturday.
BBC Northern Ireland says Thursday should be much better too.
Sky weather presenter Jo Wheeler said: “The blame for the current dismal summer has been laid squarely at the foot of the jet stream which is far further south than we’d expect at this time of year.
“This has left Britain and Ireland at the mercy of active frontal systems coming off the Atlantic, and continues to do so.
“The hope is, that the jet stream will move further north, allowing high pressure to build in the south which will give us some defence against changeable conditions.
“There was some hope that that would happen this week, but it didn’t. And that shows how difficult it is to forecast.”
