Forecast For Abersoch Issued: Friday 27th November, 2015 at 7.50am By Chas


Headline Summary: Very Windy & Wet For A Time.

General Situation: Another spell of very windy weather has arrived with gales or severe gales possible on each of the next 6 days in the Abersoch area...

Today: Low cloud this morning with some drizzle and then rain arriving during the late morning and lasting into the afternoon. The rain could be heavy for a time before clearer weather arrives sometime after mid-afternoon. Winds will again be a feature with southwesterly gales gusting to 50mph this afternoon before they veer to the west-northwest. Further high gusts are possible late in the afternoon and during the evening. Clear spells this evening, however a further shower cannot be ruled out. Mild temperatures this morning with a much colder feel later, after the rain has cleared through.

Tonight: Clear spells for a time then generally more cloud. Possible showers towards dawn. Strong to gale winds from a westerly quarter.

Saturday: Gales from the west or southwest bringing plenty of showers to the area and the showers could merge to produce some longer, wetter periods, however, there should also be some drier interludes. Those gales could be severe and are expected to gust towards 60mph at times or perhaps a bit higher and it will feel cold.

Sunday: Westerly gales or severe gales for Sunday and some further outbreaks of rain are likely during the day. Winds could gust in excess of 60mph. Feeling chilly.

Outlook: The period from Monday to Wednesday is expected to see further gales or severe gales and very changeable daytime weather. Fairly mild temperatures.

Extended Outlook: The trend for the period from Thursday 3rd December to Monday 7th December is very uncertain this morning as the charts are showing very different evolutions. GFS shows pressure building across Britain and ridging towards Scandinavia bringing fine weather with the potential for some cold-ish continental air eventually arriving. On the other hand, the ECMWF extended charts are suggesting a continuation of the unsettled weather with further gales or severe gales right through the period, with no hint of a pressure rise towards Scandinavia. Which one will be right?

For more info on the outlook from the professionals, the Met Office extended 6 to 30 day outlooks are generally very useful and are updated daily between 11.30 am and 1.30pm. They can can be found on this link here.
