Forecast For Abersoch Issued:
Tuesday 28th March, 2017 at 6.50am By Chas


Headline Summary
Start of A Changeable Few Days...

General Situation: After the fine and settled weather of the last few days, the weather is set to change today to something rather more changeable. The reason for this is that the high pressure that brought the fine spell is now losing its influence and is being replaced by more of an influence from Atlantic low pressure, that will be sending fronts across the area over the next few days. Fronts mean cloud, showers and rain, however there should be some drier and brighter periods too. At the moment, the worst of the weeks weather looks like being during tomorrow and Thursday, with today, Friday and perhaps Saturday seeing something better at times...

Today: Quiet conditions to start the day with very little in the way of wind and some early sunshine. Amounts of cloud are expected to increase through the day with the chance of one or two showers passing through the area, however, the areas of showery rain moving up from the south-southwest today are being modelled as very fragmented so it will be a bit of a lottery as to whether Abersoch sees some, or whether it stays mostly dry, with further bright spells. Winds picking up from the southeast this morning, veering south-southwesterly this afternoon and evening and perhaps gusting to fresh at times this afternoon and evening.

Tonight: Plenty of cloud, breezy, mild with perhaps a drizzly shower or two.

Wednesday: Low pressure to the west of Ireland will be feeding in fronts to the Abersoch area bringing a cloudy and unsettled day, with outbreaks of drizzle or rain on and off throughout and also some strong to gale force southerly winds. Further rain is possible on Wednesday night.

Thursday: A repeat of Wednesday's weather could be on the cards for Thursday as another area of Atlantic low pressure will again be feeding in those rain bearing fronts into the area for much of the time, along with some strong winds from a southerly quarter.


Outlook: Bright and breezy weather on Friday with a mixture of sunny and cloudy spells along with a background risk of showers passing through the area on a strong southwesterly wind. Saturday may see plenty of sunshine, though there will again be the chance of one or two showers passing through NW Wales on a brisk west to northwesterly. High level of uncertainty for Sunday, however, a ridge of high pressure could settle things down for a time.

Extended Outlook: The outlook this morning for the period from Monday 3rd April to Friday 7th April is very uncertain this morning with the period perhaps starting off with high pressure affecting the SE of Britain with more of a southwesterly and changeable scenario for the NW. There are some indications that high pressure could move in for a time during this period, bringing some settled conditions, however, there is perhaps an equal chance of the generally rather changeable, previaling weather conditions to continue.
