Cadair Idris (Gwynedd) weather

Headline:

Mostly dry this evening with late sunshine. Showers arriving overnight.

This Evening and Tonight:

Some late spells of sunshine with clear skies for many overnight. Turning cloudier by dawn with a few showers arriving in the east. Warm, muggy, and rather uncomfortable for sleeping. Minimum temperature 14 °C.

Saturday:

A mixture of sunshine and showers, these heaviest and carrying the risk of thunderstorms and hail in the north and east. Some sunshine in the southwest before rain arrives later. Maximum temperature 23 °C.

Outlook for Sunday to Tuesday:

Further showers are expected on Sunday with heavy, thundery downpours. Drier and brighter from Monday although a few heavy showers are still possible. Feeling warm in sunny spells.

Overall a rather more changeable pattern of weather through this period, compared to much of the summer thus far. Wednesday will likely see a continuation of heavy, perhaps thundery showers, although the focus may be more across the north and east by this stage. Thereafter, a general westerly or north-westerly regime looks to become established, with occasional weather systems moving in from the Atlantic. This means further rain or showers and breezy conditions at times, especially in the northwest. This will be interspersed with some drier, sunnier periods. Temperatures are expected to be close to or a little above average for most of the period. This broad pattern is likely to continue through to the end of July.

The rather changeable pattern will likely continue through into the start of August with spells of rain or showers mixed in with some drier, brighter days. However there are signs that high pressure may become rather more dominant, which could bring more in the way dry, settled weather more widely as we progress further into the month. Temperatures will likely continue to be above average overall, with the possibility of very warm or hot spells developing period, especially further south and east.
