This Evening and Tonight:

A fine end to the day, with plenty of evening sunshine. Staying dry with clear skies for many overnight with just the odd patch of low cloud developing, especially towards the east by dawn. Turning chilly with patchy frost. Windy. Minimum temperature 0 °C.

Saturday:

A chillier start, with patchy low cloud clearing fairly readily to leave a dry and sunny day. Feeling less warm than on Friday, still with a brisk easterly wind. Maximum temperature 18 °C.

Outlook for Sunday to Tuesday:

Remaining dry and settled on Sunday and into next week. Chilly nights, though daytime temperatures edging back up and feeling warm in the sunshine. Breezy at first, then winds easing.

High pressure expected to prevail early in this period maintaining largely settled conditions. This should result in largely dry weather with plenty of sunshine for most. Daytime temperatures will depend on the wind direction and cloud amounts, but most places will be warm for most of the period, and very warm days most likely will be further inland. Coasts with an onshore flow tending to be cooler. Overnight frosts are possible on clear nights where winds fall light. There is also the chance of some areas of low cloud or fog, notably around the east coast. Towards the middle of April, the weather is likely to turn more unsettled for a time with a greater chance of showers or longer spells of rain for all regions.

An unsettled period is likely around mid April, with showers or longer spells of rain at times for most. Despite being unsettled, there will be fair conditions between weather systems. A return to higher pressure is favoured later in the month with some settled spells likely to return. Temperatures are likely to be around average at first, before above average temperatures become more likely again later in the period.
