Forecast summary

Regional forecast for Wales

Becoming unsettled, and turning colder by Thursday.

This Evening and Tonight:

Generally cloudy with occasional rain and drizzle this evening and at first tonight, before this becomes more persistent and a bit heavier through the early hours, especially across west-facing hills. Another very mild night to come across Wales. Minimum Temperature 8 °C.

Tuesday:

A damp start, but the rain will ease for a time, with perhaps a glimmer of brightness around lunchtime. Some rain and strengthening winds returning later on. Mild once again. Maximum Temperature 13 °C.

Outlook for Wednesday to Friday:

Rain clearing south on Wednesday, before further wet and potentially very windy weather arrives overnight into Thursday. Brighter, but colder with a few wintry showers to end the week.

UK forecast for the next 5 days

Becoming unsettled with rain and strong winds.

This Evening and Tonight:

Mild, breezy and largely cloudy across southern areas with occasional rain or drizzle, this becoming more persistent across parts of Wales. Colder further north with a touch of frost, and a few showers across northern Scotland.

Tuesday:

A cold start in the north, then turning wet, windy and milder from the west later. Another mild day to come further south, though rather cloudy and damp at times.

Outlook for Wednesday to Friday:

Unsettled with spells of rain, accompanied by strong winds, initially in the north, but more widely on Thursday. Drier, but colder on Friday, though some wintry showers in the north.

Outlook for the UK over the next 6-30 days

UK Outlook for Saturday 25 Feb 2017 to Monday 6 Mar 2017:

Late February and early March look generally mild, changeable and at times unsettled, with Atlantic depressions pushing across the UK. This means spells of rain, some of which could be heavy across high ground in the north and west, and accompanied by windy conditions, perhaps with gales at times, again more likely in the north and west. Showers in between these Atlantic systems could be wintry over northern hills. Some wind and rain is likely for the south and east too, though with more prolonged spells of drier and brighter weather in-between. Throughout this period there remains a lower chance that high pressure centred to the southwest of the UK may become more dominant and this would mean rather more settled conditions establishing themselves, with some overnight frost.

UK Outlook for Tuesday 7 Mar 2017 to Tuesday 21 Mar 2017:

For March there is a fair amount of uncertainty, but the weather is most likely to be unsettled at first. There will be spells of wet and windy weather, interspersed with brighter and showery conditions with some snow possible across the north of the UK. There will, however, also be some drier and brighter spells, particularly in the south and east where we may see some local frost and fog at times overnight. Temperatures are expected to be a little above normal for the time of year but there remains a small chance of seeing a more prolonged cold spell, which is most probable later in the period, particularly if settled conditions develop more widely.
