It looks like next Monday a deep depression will form over the near Atlantic and move close to or over Ireland during Tuesday. Its exact path and depth are still unsure but it should be enough to bring some closure to a pretty benign couple of months' weather.
The current setup shows a deep trough over the Canadian Maritimes and a 1030 hPa Azores anticyclone, both causing a warm humid southeasterly flow over the western Atlantic. The jet is strengthening, and a surface low is now forming and will move towards Iceland over the weekend. The key feature is an upper shortwave trough following from behind, which will tighten the gradient further and form a 180 kt jet streak late on Sunday and will cause a second surface low to form and deepen rapidly during Monday. Depending on the rate of occlusion of this low, it will dive southeastwards and will pass very close to or over Ireland during Monday night and Tuesday.
A wet and windy day is in store, with strongest winds probably on the storms western flank. It's not worth noting exact details at the moment but it is one to keep an eye on over the next few days.
The GFS paints the most severe picture, but I would imagine it will step this down slightly in future runs. But it looks like the start of a much more mobile Atlantic phase.
