National Outlook

Outlook: It'll become more mixed to end the week and as we move into the Bank Holiday weekend and it'll become less warm too, but still with temperatures above average generally for a time. There'll be a gradual shift to generally more unsettled conditions then over the weekend with a mobile Atlantic regime taking over, with temperatures continuing to taper back a little bit further.



Wednesday night: There'll be clear spells and the likelihood of some scattered thundery showers for a time on Wednesday night. Cloud will increase in the south and west bringing a little patchy drizzle and mist and with some fog too, especially in the south. Lowest temperatures of 11 to 16 in mostly moderate east to south-east winds, fresher at times in eastern coastal parts.

Thursday: While there'll still be some sunny spells for a time in parts of the east and north, it'll become rather cloudy generally, with a little patchy light rain, drizzle and mist in places. It'll stay mainly dry in the east though. Later in the day it'll brighten up a little from the west. It'll be less warm than recent days with highest temperatures of 17 to 24 degrees, warmest further east, in moderate, occasionally fresh south to south-east winds, veering southwesterly

Thursday night: Becoming mainly dry for a time with clear spells as the patchy light rain and drizzle clear to the northeast. However some scattered showers will move into parts of the northwest. Lowest temperatures of 10 to 13 degrees in mostly moderate south-west winds, fresh to strong in coastal parts of the northwest.



Friday: There'll be a few scattered showers for a time, mainly in Ulster, otherwise it'll be a dry day with some pleasant sunny spells. Highest temperatures will range around 17 to 22 degrees, warmest in the east. It'll be a little cooler in coastal parts of the west and northwest, in moderate, occasionally fresh southwest to west winds, stronger for a time in northwestern coastal parts, but the winds will ease light to moderate later.



Saturday: It'll start off mainly dry at first on Saturday with some sunny spells in the east. However, outbreaks of rain will move into the west early on and spread eastwards through the morning and afternoon, with some of that on the heavy side later, especially further north. A clearance to sunny spells and scattered showers will start to follow from the west later, some of those possible heavy, and with the chance of a thundery downpour later in the north. Highest temperatures of 16 degrees along the west coast to around 21 degrees in the east with southerly winds gradually increasing moderate, occasionally fresh, and veering southwesterly later.

Sunday: There'll still be some lingering scattered showers on Sunday, especially further north, but these will become isolated into the afternoon, with a good lot of dry weather overall and with some spells of sunshine. Highest temperatures of 15 degrees in the west up to 19 degrees in the east, in moderate, occasionally fresh, westerly winds.

The rain will clear eastwards with sunshine and scattered showers following. Highest temperatures of 15 degrees in the west and up to 20 degrees in the east.
