Forecast For Abersoch : Tuesday 19th March, 2024 - Issued at 7.45am by Chas

   

 

 

Headline Summary: Some Fine Spells Today - Rain Tonight.

 

The forecast is back after a few weeks of illness and I hope to be able to maintain daily updates again going forward - fingers crossed!!

 

Bore da - Good morning from Abersoch. It is a fine start to Tuesday and this comes after a pretty decent Monday, which also saw some spells of sunshine coming and going, before some evening rain, however, temperatures struggled to get to 11c. This was in contrast to the north coast of Wales which saw warmer temperatures, with the Bangor area seeing closer to 14c.

 

Rain will return tonight and may linger through tomorrow morning, with something drier for the afternoon. We then have changeable and very windy weather on Thursday, followed by a bright and breezy, shower lottery on Friday.

 

This morning's models continue to show chillier northwesterly winds for next weekend, so there should be drier and sunny spells, but also some showers and at the moment, the highest risk of showers may be on Saturday, with the best of any sunshine on Sunday...

 

Today: Tuesday: Potentially OK during the daytime period today, with morning sunshine and patchy cloud coming and going. More of the same this afternoon for a time, but generally cloudier later. Winds from the west-southwest, but the breeze should fall lighter as the day goes on and drop out later. Temperatures up to 11c during the day. Rain is expected to arrive later in the evening and last on and off through the night. An easterly may pick up later in the night.

 

Wednesday: Morning rain or drizzle giving way to drier and brighter weather during the afternoon. Timings uncertain, but at the moment the wet weather may last into the early afternoon, with any sunshine coming during the second half of the afternoon / early evening. Winds from the north or northwest during the afternoon, gusting moderate to fresh. Max temperatures up to about 10c. Light winds overnight and temperatures could come down close to grass frost levels.

 

Thursday: Perhaps a spell of early cloud and showers, then a good chunk of the day could be OK with variable amounts of cloud. The risk of showers may increase again later - timings very uncertain. Winds increasing from southwest during the day and bcoming gale force. Milder later after a chilly start to the day. Some rain overnight.

 

Friday: A blustery day with strong to gale force westerly winds and a shower lottery scenario, but there should be some spells of sunshine too. Feeling chilly.

 

Saturday: A cold and gale force northwesterly wind feeding in variable amounts of cloud, sunny spells and the chance of heavy, blustery showers. Temperatures may not get to 10c.

 

Outlook: Sunday may be OK, with a northerly breeze, with the shower risk perhaps lowering and we may see some decent spells of sunshine, however, temperatures will remain fairly subdued. High levels of uncertainty by Monday and Tuesday with some mixed messages from the models, but some charts show some quite cold conditions arriving.

 

Extended Outlook: The outlook for the period from Wednesday 27th March to Sunday 31st March... is for very changeable weather, with a mixed bag of conditions and low pressure in the ascendancy. Some charts suggest quite a chilly few days too.

 

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...
