Scilly St Marys (Isles of Scilly) weather

Headline:

Further spells of wet and windy weather to come.

Today:

The morning should start dry, but cloud will soon thicken with wet and potentially very windy weather sweeping across the region. The rain will become heavy, but it should turn more showery later. Winds remaining brisk. A mild day though. Maximum temperature 13 °C.

Tonight:

The evening will begin cloudy with blustery showers. Showers should become confined towards western coasts overnight with clear periods developing. Remaining breezy, although this should prevent a frost from forming. Minimum temperature 7 °C.

Friday:

Apart from a scattering of showers, mainly in the west, Friday promises to be a much drier and brighter day with sunny spells. Feeling cool due to the breeze though. Maximum temperature 11 °C.

Outlook for Saturday to Monday:

After a mostly fine start, wet and windy weather will move eastwards across the region on Saturday. Sunday and Monday look cloudy with further patchy rain. The wind easing though.

Unsettled conditions are likely to continue at first, with low pressure probably centred somewhere to the southwest of the UK, whilst high pressure becomes established to the northeast. This means a broadly easterly flow will become increasingly dominant through next week, whilst periods of rain or showers become increasingly confined to southern or southwestern parts. With time, high pressure is signaled to become more dominant with more in the way of dry, settled weather anticipated though there could be some isolated showers to eastern parts, that could perhaps be wintry at times. Temperatures will lower compared to recent weeks, closer to or perhaps a little below average for many. Overnight frost and fog or freezing fog could become more prevalent, though any particularly cold conditions look unlikely at this stage.

High pressure is fairly likely to be close by to the UK at the start of this period, though its exact position is rather more uncertain. This means a continuation of predominantly settled and dry weather for many, albeit with the potential for overnight frost and fog. With colder air likely near to or over the UK, the chance of wintry hazards is higher than in previous weeks. Towards mid-month, there is the potential for rather more changeable conditions to become re-established, although confidence in this aspect of the forecast is currently low.
