St Mary's Airport (Isles of Scilly) weather

Headline:

Increasingly cloudy with rain in the west.

This Evening and Tonight:

Mainly dry in the east with plenty of evening sunshine and clear spells overnight. Increasingly cloudy in the west, with fog spreading readily across the Moors, and patchy light rain arriving by dawn. Feeling warm and muggy. Minimum temperature 16 °C.

Friday:

Early cloud breaking and lifting with sunny spells to follow. Mostly dry although occasional showers may pop up through the afternoon. Breezy along the coast but warm in the sunshine. Maximum temperature 26 °C.

Outlook for Saturday to Monday:

Unsettled. Showers may be heavy and blustery at times with the risk of thunder, especially on Sunday and Monday, though some brighter breaks are possible too. Humid and muggy.

Overall a rather more changeable pattern of weather through this period, compared to much of the summer thus far. Tuesday 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 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 average out above normal with some humid conditions possible at times making it feel particularly warm in any sunshine. This broad pattern is likely to continue through to the end of July.

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