This Evening and Tonight:

A fine evening with some sunny spells, followed by clear skies overnight. Winds remaining light and turning chilly by dawn with the odd patch of frost likely. The odd patch of mist, fog, or low cloud also possible. Minimum temperature 2 °C.

Tuesday:

Fine with plenty of warm sunshine, once any early patches of low cloud or fog clear. Feeling cooler in the strengthening breeze, especially along eastern coasts. Another chilly night follows. Maximum temperature 15 °C.

Outlook for Wednesday to Friday:

Dry, sunny and warm Wednesday and Thursday, but cooler in the breeze and chilly overnight. Low cloud or fog perhaps spreading south and west overnight into Friday, and feeling cooler.

High pressure will tend to dominate through this period, often centred to the north or northeast of the UK, maintaining largely settled conditions for much of the time. This should result in lengthy spells of dry and bright weather, but with a risk of patchy overnight frosts where winds fall light. There is also the chance of some areas of low cloud or fog, especially around some coasts. Later in the period, it may turn more unsettled at times as rain or showers try and push in from the west. It will be breezy at times, especially in the southwest early on. Daytime temperatures will tend to fluctuate depending on the wind direction and cloud amounts, with the potential for warm conditions at times but also cooler interludes.

Weather patterns are most likely to remain fairly slow-moving through the second half of April. High pressure may remain centred to the north or northeast of the UK, potentially bringing more fine and dry weather. However, there may also be some interludes of rain or showers, these perhaps more likely to affect southern and western parts of the UK. Temperatures are likely to be around or a little above average overall, and feeling warm inland at times during the day, although some chilly nights are still possible under any clear skies.
