Regional forecast for Wales

Showers dying out overnight. Drier and brighter much of Saturday.

It will be a drier day across the country with sunny spells. However, cloud will increase from the southwest later in the afternoon with rain arriving during the evening. Maximum Temperature 16C.

Outlook for Sunday to Tuesday:

Rain clearing to blustery showers on Sunday. Showers at first on Monday followed by further heavy rain. Sunshine and heavy thundery showers on Tuesday. Windy at times and mainly cool.

UK forecast for the next 5 days

Drier and brighter on Saturday, though rain spreading north-eastwards later.

This Evening and Tonight:

Showers will gradually become confined to north-western coastal fringes and the far north, giving a predominantly dry night for most. Clear spells will allow temperatures to fall low enough for a local rural grass frost.

Saturday:

Drier and brighter for many with sunny spells. However, showers will affect northern Scotland and patchy rain will reach south-western parts during the afternoon.

Outlook for Sunday to Tuesday:

Rain clearing to blustery showers on Sunday. Showers at first on Monday followed by further heavy rain. Sunshine and heavy thundery showers on Tuesday. Windy at times and mainly cool.

Outlook for the UK over the next 6-30 days

UK Outlook for Wednesday 3 Jun 2015 to Friday 12 Jun 2015:

Many places should be dry on Wednesday with some sunshine, the best of this in southern and eastern areas. More unsettled conditions, with outbreaks of rain and brisk winds, probably spreading into northern areas later on Wednesday and during Thursday, with the south probably remaining dry, and warmer than we've seen recently. Thereafter it looks as though high pressure will become established over northern parts of the UK, bringing generally dry, fine conditions for most. There is a risk later in the period that the south will see some heavy and thundery showers spreading up from the continent. Temperatures generally warm or very warm in most inland areas. Coastal areas in the east, may well be a little cooler at times with winds off the chilly North Sea.

UK Outlook for Saturday 13 Jun 2015 to Saturday 27 Jun 2015:

High pressure looks as though it will be established across the north of the UK during much of this period. This will bring fine and dry conditions to most parts with warmer conditions than of late across the north, and especially the northwest. It is also expected to be very warm in the south, although here there is a risk of some heavy and thundery showers spreading up from continental Europe. Confidence in the forecast evolution declines towards the end of June; however, the general trend looks set to remain similar, with drier conditions in the north, some showers possible in the south, and generally warm temperatures.
