Caernarfon (Gwynedd) weather

Headline:

Storm Dave brings disruptive winds later Saturday, quietening down thereafter.

This Evening and Tonight:

Some breaks in the cloud possible giving a brighter end to the day, perhaps an isolated light shower. Skies turning cloudy again towards dawn. Blustery winds gradually easing through the evening, remaining lighter overnight. Minimum temperature 4 °C.

Saturday:

Cloud and light patchy rain quickly spreading northwards, some brighter spells possible from afternoon onwards. Turning increasingly windy as Storm Dave arrives with gales developing from mid-afternoon. Maximum temperature 13 °C.

Outlook for Sunday to Tuesday:

Bright but blustery on Easter Sunday, with scattered showers. Winds easing leaving a drier, brighter, and warmer Easter Monday. Generally settled on Tuesday, potential for cloud and isolated showers later.

Rather changeable conditions are expected through this period, as Atlantic frontal systems track eastwards across the UK, accompanied by some strong winds at times. These will bring occasional spells of rain or showers, heaviest and most frequent in the west and northwest, with longer drier interludes likely in the south and sheltered eastern areas. Whilst temperatures will be close to average for the period as a whole, there may be opportunities for some short-lived warm spells in the south and east. Conversely, occasional colder interludes in the northwest will bring the chance of some wintry showers, especially to hills, and overnight frost.

It is probable that more blocked, or at least slowly evolving, weather patterns will become increasingly dominant through the middle of the month. Whilst confidence is low, this may result in more settled and drier conditions overall. There may, however, still be some more unsettled interludes at times, especially in the south and southwest. Temperatures will probably be around or a little above normal for the period as a whole, and its possible we may see some pleasantly warm spring weather at times.
