Its will will be mostly cloudy over Connacht and Ulster with some sunny spells across Munster and south Leinster over the day.

Wednesday night will be mostly dry across Ireland with clear spells in most places with the small risk of some drizzle over the northwest for a time. Temperatures over night will range between 8C to 12C.

THURSDAY 27TH SEPTEMBER

A few light showers possible over western and northern parts on Thursday with cloud increasing there over the afternoon over the south and east it will remain dry with sunny spells with some sunny spells also possible across southern connacht. temperatures between 15C to 19C across Ireland.

FURTHER OUTLOOK

Early next week looks set to start of dry across Ireland with high pressure still in place there could be a few light showers now and again but the main outlooks is for very small amounts of rain over the coming week. Later next week it may turn a little more on settled again and also colder as winds turn more northwesterly and northerly in directions taken in a colder air mass with a risk of frost over the start of October.

At the end of the month into October another thing we need to watch out for is Sub Tropical storm Leslie which is current in the tropical waters of the Atlantic with its path not known. the GFS and ECMWF hint it could move near western Europe but where is yet to early to say yet. It can be seen on the above model runs of the west of Ireland into the start of October.

Below you will see the latest track map from the Hurricane center of Sub Tropical storm Leslie

The initial motion is estimated to be an eastward drift, or 090/4 kt within the increasing mid-level westerly steering flow. A turn to the east-northeast is forecast as an approaching mid-latitude trough and associated cold front approaches from the northwest over the central Atlantic. The deterministic guidance indicate that the aforementioned baroclinic system will overtake Leslie near the 48 hour period, and influence a transition to a non-tropical low pressure system. Subsequently, the GFS and the European models still show extratropical Leslie as the primary system and deepening with time. For now, the official forecast will indicate a merging scenario, but succeeding advisories may include extratropical low forecast points through day 5.
