National Outlook

Overview: A gradual transition to less warm and humid conditions takes place this weekend as Atlantic influence increases, bringing lower temperatures and more changeable conditions.

Friday Night: Most of the showers will die out on Friday evening and night leaving clear spells for many, at least for a time. Cloudier conditions near the south coast with patchy rain and drizzle will gradually extend northwards over the country overnight. Still rather mild and muggy with lowest temperatures of 15 to 17 degrees, and moderate southerly winds, fresher on some southern and western coasts.

Saturday: Cloud and outbreaks of rain in the west will gradually spread eastwards over the country on Saturday. Some heavy bursts are possible. There will still be some drier and brighter interludes, these probably at their best in the east and northeast during the morning. Highest temperatures of 17 to 23 degrees, warmest in the east and northeast, with moderate to fresh southerly winds easing light to moderate in the evening. Cloud and outbreaks of rain will give way to showers and clear spells spreading from the west on Saturday night. Lowest temperatures of 11 to 15 degrees in light to moderate southwesterly winds.

Sunday: Sunday will bring a mix of sunny spells and scattered showers, occasionally heavy. The showers will be mainly in the west and north at first but they'll spread elsewhere in the afternoon and evening. Highest temperatures ranging from 15 degrees in the west to 20 degrees in the east in light to moderate southwest to west winds.

Monday: Current guidance suggests a mix of cloud and hazy sunny spells and just well scattered showers for much of Monday. Cloud and rain may start to advance from the Atlantic in the evening though. Highest temperatures of 16 to 20 degrees. Light to moderate southwest winds will ease light southerly or variable in the evening.

Further Outlook: A changeable Atlantic regime looks set to persist. Temperatures will be near average for the time of year, with values typically in high teens or low 20's.
