Good evening Western Isles and welcome to your latest Weather Watch blog.

On this Wednesday afternoon we are slowly starting to dry out. The heaviest of the rain for most has now cleared away behind it we are seeing some sunshine and blustery winds. There are a few heavy showers still lingering and winds are still gusting 30 to 40 mph.

The rest of this evening is going to see further sharp showers but these will be fairly scattered we are going to see some sunshine with cloud increasing as the evening progresses winds of 20 to 30 mph and at times gusting 40 mph.

Today’s view from space is showing overcast conditions but you can clearly see the area of low pressure out west.

Thursday across the Western Isles and we are going to see another overcast day with some sunny spells a few showers this will be mainly light and well scattered. It’s going to be another breezy day with strong south-westerly winds and feeling warm warmer than it has done of late anyway.

A little quirk on the surface pressure chart today shows tropical storm Chantal out in the middle of the Atlantic expected to dissipate in the next couple of days.

Thursday across the UK and to be a windy day with a good deal of sunshine and cloud for England and Wales showery for the north and west. Low-pressure for the north and west high-pressure for the south.

Friday across the Western Isles and we are going to see yet again another windy day with further strong winds gusting 30 to 40 mph occasionally reaching 50 mph and further heavy rain.

Tropical storm Chantal still sits out in the north Atlantic with very little or no movement.

Friday across the UK and turning a good deal warmer temperatures reaching the high 20s possibly even 30°C for the south and east. Lighter winds and drier for the north and north-west.

Saturday across the Western Isles and conditions are finally going to become more settled. Light winds mainly dry but the cloud dominating with the weather fronts sitting out west. It should be a warm day.

Saturday across the UK and another largely fine and ride a high-pressure dominates with a cold front sitting out west which will introduce a fair old amount of cloud and some light rain and drizzle.

In global weather news we now have the third name storm of the 2019 Atlantic hurricane season Chantal. This tropical storm is not expected to do much. It will meander out in the Atlantic before eventually dissipating in a few days time.
