Forecast For Abersoch : Saturday 27th April, 2024 - Issued at 7.35am by Chas

Headline Summary: Bright At Times But Turning Cloudier.

Bore da - Good morning from Abersoch... Friday was not too bad a day at all, with the glorious early sunshine followed by a mix of sunny and cloudy spells, with sheltered sunny spots feeling very pleasant again, despite a chilly northeasterly breeze. There was rain not too far away to the south of us, but we managed to avoid it up here on Pen Llyn.

The latest precipitation radar images show rain rain affecting the far south of Wales this morning and some rain out to the west in the Irish Sea. The area of rain to the south is expected to edge up towards us during the day, but it will be becoming fragmented, so by the time it gets here, it may have fizzled out to producing not very much at all.

An area of low pressure is expected to move up the eastern side of the UK tonight and on Sunday, bringing rain to central and eastern parts, but out here to the west, we should do OK for sunshine tomorrow, though we will again have a chilly wind with a northerly element.

Thereafter, Atlantic low pressure to the west or southwest of Britain is expected to bring the risk of something rather more unsettled to start the working week, with strong winds from a southerly quarter, followed by the chance of a better second half to the week...

Today: Saturday: Some bright spells this morning with variable amounts of cloud and a low-ish risk of a brief shower. Winds from the east-northeast, moderate to fresh at times, feeding in more in the way of cloud this afternoon. The risk of one or two light showers may increase for the second half of the afternoon and evening- but it should be dry for most of the time. The breeze will feel chilly today, with temperatures still struggling to get much above 10c. Variable amounts of cloud and clear spells overnight with a fresh wind from a northerly quarter.

Sunday: Spells of sunshine on Sunday with the chance of some prolonged spells in the afternoon. Winds from the northwest, up to fresh in strength and backing to the west then southwest later. Air temperatures again struggling during the day, but sheltered spots should do well for warmth in the sunny spells. Clear spells for a time in the evening, but showers are expected overnight.

Monday: Winds gusting to gale and from a southerly quarter, with plenty of cloud and outbreaks of rain.

Tuesday: Strong southeasterly winds on Tuesday and further outbreaks of rain are possible - though the timing of any wetter spells is uncertain. Temperatures milder by this time.

Wednesday: Loads of uncertainty, but perhaps a better day with mild temperatures, with some sunny spells. Rain possible overnight.

Outlook: For the period from Thursday to Saturday, there are some mixed messages from the models, but there are charts suggesting something drier and brighter at times, so a decent few days is a possibility.

Extended Outlook: The outlook for the period from Sunday 5th May to Thursday 9th May ... is very, very uncertain, but there is a suggestion that the start of the period could be OK - which would be good news for the second half of the holiday weekend.

Charts below are a snapshot from the major models. Note that anything beyond about 5 days is pretty speculative - so treat all extended charts with caution...
