Forecast For Abersoch Issued:
Friday 20th January, 2017 at 7.05am By Chas


Headline Summary
Quiet Weather Again But Brighter.

General Situation: The quiet weather is set to continue today, with some much clearer skies in comparison with recent days and these may continue through tomorrow too. Looking further ahead and there is still some uncertainty as to when the Atlantic will break though the block of high pressure out to the east, however, as low pressure does edge in during next week, whether it breaks through or not, it will bring some very cold feeling and strong winds from the south or possibly southeast and eventually some rain - the timing of which is highly uncertain and could be delayed further. There is a low possibility of southeasterly winds dragging in colder air and perhaps bringing a threat of snow to higher ground of Wales as fronts try to edge in later in the week - only a low possibility, but one to keep an eye on...

Today: Quiet and chilly start with clearing skies bringing colder temperatures before things warm up a little in the sunny spells this morning. Mostly fine this afternoon with the chance of plenty of sunshine and with light breezes, it should feel pleasant. Bit more of a breeze this evening, but perhaps cold enough for a touch of frost in the sheltered spots.

Tonight: Clear skies with a light breeze from an easterly quarter with a ground frost, especially for sheltered spots.

Saturday: Some lovely weather for Saturday with a clear and cold start, with frost possible in sheltered posts and a mostly sunny day is likely with light breezes from the southeast, which may drop out for a time, so potentially feeling pleasant in the sunshine, but cold in the shade. Clear skies and cold temperatures for Saturday evening with perhaps more in the way of cloud overnight.

Sunday: Generally more in the way of cloud on Sunday with a chilly southeasterly breeze and perhaps a very light shower or two running through the area, though it looks like being dry for the majority of the day. The cloud may break up at times to allow through some sunny intervals. Feeling cold.

Outlook: The period from Monday to Wednesday looks like starting dry, bright and chilly with plenty of sunshine for Monday and Tuesday with a noticeably cold wind picking up from the south or southeast. The dry weather may continue on Wednessday, however, that south or southeasterly wind may be gale force by then and if that is the case, then it will feel very cold indeed.

Extended Outlook: The outlook this morning for the period from Thursday 26th January to Monday 30th January is for low pressure to edge in from the west bringing strong or gale force winds from a southerly quarter and eventually some rain, the arrival of which remainbs very uncertain. Perhaps milder for the second half of the period with southwesterly winds.
