Headline:

Storm Amy to bring potential disruption.

Today:

Any early brightness soon giving way to increasingly grey skies as Storm Amy drives rain, heavy at times, across the country with gales developing in the afternoon. A mild day despite the widespread cloud. Maximum temperature 18 °C.

Tonight:

Rain clearing during the evening with scattered showers and clear spells overnight. Remaining very windy with continuing gales, locally severe in exposed areas. Rather humid evening, feeling fresher by dawn. Minimum temperature 7 °C.

Saturday:

Unsettled with showers and longer spells of rain. Sunnier spells are possible, but feeling noticeably cooler than of late with brisk northwesterly winds and further gales. Maximum temperature 14 °C.

Outlook for Sunday to Tuesday:

Winds easing from Sunday as Storm Amy moves away, though remaining breezy. Some sunny spells in the east, but often cloudy further west with patchy rain, chiefly around hills.

A broadly westerly pattern to start, allowing maintain relatively mild conditions, especially by night, and with frontal systems moving in from the Atlantic. These will bring further spells of rain or drizzle and strong winds at times, these more likely affecting northern and western areas, and especially windward high ground. Eastern areas generally look drier. By the following weekend (11/12 October), there is a signal for pressure to build to the west or southwest of the UK, whilst low pressure becomes more prevalent to the east. This means the bulk of the wet and at times windy weather could shift to affect more eastern areas, with the best of the dry weather towards west or southwest. Within this pattern, there is the possibility of slightly cooler conditions developing.

The latter half of October will probably see a transition to more widely unsettled conditions once more. Whether this takes the form of successive depressions moving in from the Atlantic or a rather slower evolving weather pattern remains to be seen, but there is a greater chance of more places seeing more frequent spells of rain or showers and possibly strong winds. Temperatures probably close to average overall.
