Good Morning and happy new year, everybody. I hope you all got 2017 off to a good start, and your new year’s weather was better than mine, which amounted to freezing fog, sub-zero temperatures, and snowfall at the airport on the way back. Anyway, as far as Ireland is concerned, the cold spell over the past few days is coming to an end as a large, but weak low pressure system tracks northwards from the Azores. At the same time, a high pressure wedge centered north of Ireland will track eastwards towards Norway, clearing the way for more turbulent Atlantic weather patterns.
For most of Wednesday, this does not amount to much. We’re still in the grip of the high pressure area, meaning that rainfall is pretty much out of the question, despite a pretty much solid cloud cover. It will also remain cool, with daytime highs struggling to exceed 5°C for most of the day, before dropping back to just above freezing for the first half of the night. Things will start to change overnight, though, as the high starts to move off.
Temperatures will rise on Thursday, reaching 6-7°C in the morning, and peaking at 9°C at midnight. Some early fog should clear quickly in the morning. It will remain dry for most of the day, however by the evening, a band of rain associated with a warm front will move into Cork. This will stay overnight and yield some impressive rainfall totals, so spot flooding is possible. At around the same time, winds will swing around to a southerly direction and freshen up to around Force 6-7, although gale to storm force gusts are also possible.
Friday will continue to be wet, although not quite as windy, with Force 4-6 winds expected. The worst of the rain will have moved off by Friday morning, however drizzles and light showers are possible throughout the day. It will be mild, though. Daytime highs will be around 11°C, with low temperatures at night not falling below 7-9°. The weekend looks like it will be more of the same, with Sunday appearing to be the better day.
