Some humid days south

An ongoing west to southwesterly weather pattern brings periods of wind and rain in from the Atlantic during this week. The most prolonged rain will affect north-western parts of Britain and Ireland, whilst central and south-eastern areas will be often dry. Temperatures varied, occasionally warm humid, but generally cool in the north-west. By the weekend, temperatures may lift more widely.

Slow moving fronts affect north-western areas, bringing heavy rain to western Scotland and Ireland, extending to Cumbria. Rain or drizzle for west Wales. The south-west may be also grey and damp.

A brisk southwesterly wind, strongest around the Irish Sea. Just 15 to 18C or cooler north & west, but up to 25 to 28C south-east.

A cold front passes south-east across Britain overnight and into early Thursday (timing uncertain). Rain for a few hours, some heavy showery bursts with possible thunder. Sunny spells coming through, but further frequent showers are expected in the west & north-west. Brisk west to southwesterly winds, gusty as the front moves through. Fresher air extends to all areas, highs 18 to 23C, warmest south-east. Cooler in western Scotland, nearer 15C.
