St Catherine's Bay (Orkney Islands) weather

Headline:

Haar and low cloud with some heavy showers.

This Evening and Tonight:

Some evening sunshine for Orkney, but haar before spreads north late evening and overnight, becoming extensive across eastern Orkney and western Shetland. Mainly dry but a few isolated showers, mainly towards the end of the night. Minimum temperature 13 °C.

Saturday:

Haar soon clearing west coast of Shetland, but likely to affect Orkney for much of the day, most extensive in the east. A few heavy showers. Maximum temperature 18 °C.

Outlook for Sunday to Tuesday:

A few showers but these will be interspersed with warm and sunny spells. Low cloud could be extensive at times with occasional haar.

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.
