Wales weather forecast
Headline:
An overcast and damp few days.
Today:
A wet start for many, though the far north may remain dry much of the morning despite being mostly overcast. Drier briefly everywhere around lunchtime, before a renewed spell of rain sweeps in mid-afternoon. Feeling muggy under the thick cloud. Maximum temperature 20 °C.
Tonight:
Remaining wet throughout the night for most parts. The persistent rain may be replaced by heavier, more showery rain and gusty winds in the far south later in the night. Minimum temperature 12 °C.
Thursday:
Another predominantly overcast day with patchy rain around for most, though there will be drier interludes from time to time. Some brightness creeping into the far west during the evening. Maximum temperature 20 °C.
Outlook for Friday to Sunday:
Friday looks brighter with sunny spells, though with a few showers. Mainly dry with sunny spells for the weekend, which will also gradually become warmer.

UK long range weather forecast
Through the majority of this period, it will be mostly dry and settled for many areas, especially in the south of the UK. More unsettled conditions with spells of rain and strong winds may affect the north and northwest at times. These unsettled conditions could spread to other parts of the UK later in this period, but widespread unsettled conditions are unlikely. Temperatures are likely to be mostly around normal, although it may become warm for a time in the south and perhaps very warm in the southeast. Towards the end of the period, conditions may start to trend towards more generally settled weather for most areas, but with the possibility of the occasional bout of wetter weather.
Updated:
Although confidence remains low throughout this period, the preferred scenario favours a more settled regime. There should be plenty of dry, fine weather around, though there is still the risk of occasional bouts of rain and strong winds. Such spells are mostly likely across the north and west, but they could spread to other areas at times. Temperatures generally around average, with any periods of particularly warm weather most likely being short-lived.
